Properties of lonic compounds are_____
at room temperature.
Compared to H2S, the higher boiling point of H2O is due to the
1.
greater molecular size of water
2.
stronger hydrogen bonding in water
3.
higher molarity of water
4.
larger gram-formula mass of water
Answer:
2, stronger hydrogen bonding
Explanation:
[tex]\rm H_2O[/tex] has higher boiling point than [tex]\rm H_2S[/tex], as there has been stronger hydrogen bonding in [tex]\rm H_2O[/tex]. Thus, option 2 is correct.
The boiling point has been the temperature at which the liquid has been converted to the gaseous form. The boiling point has been based on the intemolecular attractions between the atoms.
Higher boiling pointBased on the intermolecular interactions, the compound with higher intermolecular force required more energy to break the bond and change the state, and thus have high boiling point.
The hydrogen sulfide and water has hydrogen bonding. The hydrogen bonding has been based on the electronegativity of the atom involved. The more electronegative atom, stronger will be hydrogen bonding and thereby higher boiling point.
In [tex]\rm H_2S[/tex] and [tex]\rm H_2O[/tex], the oxygen has been more electronegative than sulfur and thus results in stronger hydrogen bonding.
Thus, [tex]\rm H_2O[/tex] has higher boiling point than [tex]\rm H_2S[/tex], as there has been stronger hydrogen bonding in [tex]\rm H_2O[/tex]. Thus, option 2 is correct.

The Texas high plains region does not revive much rain. It is reasonable to predict that this region, compared to other ecoregions, would have
Answer:
Less soil erosion
Explanation:
Due to the low amount of rainfall in this region, it is easier to say that the region compared to other ecoregion will suffer less soil erosion.
Erosion is usually the washing away of the top layer of the soil. Rainfall is one of the most important element that causes erosion. Surface runoff for an extended period of time can remove the topmost layer of the earth on which plant can grow. This starves the soil of its rich nutrients and minerals.

Describe the relationship between Chemistry and PCR test
Answer:
In Chemistry, proteins are defined as biomolecules that are essential for the human body to maintain homeostasis. In a PCR test, short for Polymerase Chain Reaction test, scientists are tracking for a certain chemical substance in our body that may be present in the process of protein synthesis or DNA replication that could possibly show if a person is positive for the Corona Virus.Therefor, the relation between Chemistry and the PCR test is that, without Chemistry, the PCR test would not be able to stand on its own, which in other words means the PCR test is dependent upon the presence of Chemistry.

a.the gas y is a water vapor.
b.water is an element.
c.the gases x and y are compounds.
d.the gases x and y are elements
Answer:
d.the gases x and y are elements
Explanation:
Since it is impossible to further break down the gases produced during this electrolytic process, we can conclude that the gases x and y are elements.
An element is a distinct substance that cannot be split up into simpler substances. Such substances are made up of only one kind of atom.
It is impossible through chemical reactions split an element into simpler units.

how many grams of molecular oxygen (O2) is produced from 13.8 grams of calcium chlorate (Ca(ClO3)2)in the following chemical reaction?Ca(ClO3)2→CaCl2+ 3O2
Answer:
6.72 g
Explanation:
Given data:
Mass of calcium chlorate = 13.8 g
Mass of oxygen produced = ?
Solution:
Chemical equation:
Ca(ClO₃)₂ → CaCl₂ + 3O₂
Number of moles of calcium chlorate:
Number of moles = mass / molar mass
Number of moles = 13.8 g/ 206.98 g/mol
Number of moles = 0.07 mol
Now we will compare the moles of oxygen and calcium chlorate.
Ca(ClO₃)₂ : O₂
1 : 3
0.07 : 3×0.07=0.21 mol
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 0.21 mol × 32 g/mol
Mass = 6.72 g
A seismograph is usually placed on the surface of the ground to feel any vibration.
True
False
Answer:
So yes it True.
Explanation:
A seismometer is the internal part of the seismograph, which may be a pendulum or a mass mounted on a spring; however, it is often used synonymously with "seismograph".
Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic network. The earliest "seismoscope" was invented by the Chinese philosopher Chang Heng in A.D. 132. This did not, however, record earthquakes; it only indicated that an earthquake was occurring. The first seismograph was developed in 1890.
A seismograph is securely mounted onto the surface of the earth so that when the earth shakes, the entire unit shakes with it EXCEPT for the mass on the spring, which has inertia and remains in the same place. As the seismograph shakes under the mass, the recording device on the mass records the relative motion between itself and the rest of the instrument, thus recording the ground motion. In reality, these mechanisms are no longer manual, but instead work by measuring electronic changes produced by the motion of the ground with respect to the mass.
A seismogram is the recording of the ground shaking at the specific location of the instrument. On a seismogram, the HORIZONTAL axis = time (measured in seconds) and the VERTICAL axis= ground displacement (usually measured in millimeters). When there is NO EARTHQUAKE reading, there is just a straight line except for small wiggles caused by local disturbance or "noise" and the time markers. Seismograms are digital now - there are no more paper recordings.

A seismograph is placed on the surface of the ground to detect any vibration. Therefore, the given statement is correct.
What is a seismograph?A seismometer can be described as an instrument that responds to ground noises and shaking such as earthquakes, volcanic eruptions, and explosions. Seismometers are generally attached with a timing device and a recording device to create a seismograph.
The output of such a device is recorded on paper or film, now recorded and processed digitally known as a seismogram. This data is used to locate and characterize earthquakes, and to study the internal structure of the earth.
A seismoscope is used to trigger the device to start recording, and then a recording surface would form a graphical illustration of the tremors automatically.
A seismometer feels the up-down motions of the Earth that move along with any motion detected. The relative motion between the weight and the frame offers a measurement of the vertical ground motion.

Explanation:
An acid (A) will have acid in the name. It will also have a hydrogen bonded to an electronegative compound. A molecular compound (M) will have nonmetals and/or hydrogen. An ionic compound (I) will have nonmetals and first and second column metals. It could also include charged compounds. A transition metal (TM) will have a transition metal in the compound.
The formulas for TM and I are made by balancing the charges of the atoms to equal zero. The formulas for M can be found from the name itself. The formulas for A have to be memorized.
TM ==> copper (II) oxide ==> CuO
A ==> hydrosulfuric acid ==> H₂S
TM ==> iron (III) fluoride ==> FeF₃
TM ==> lead (II) chlorate ==> PbCl₂
A ==> hydrochloric acid ==> HCl
M ==> dihydrogen monoxide ==> H₂O
A ==> sulfurous acid ==> H₂SO₃
I ==> potassium oxide ==> KO
I ==> ammonium hydroxide ==> NH₄OH
M ==> nitrogen trioxide ==> NO₃
I ==> aluminum phosphate ==> AlPO₄
To name ionic (I) compounds, simply put the name of the metal with the nonmetal. But, for the nonmetal change, the ending to "-ide". To name acids (A), say hydro- with the atom/compound it is attached to and end with acid.
I ==> MgSO₄ ==> magnesium sulfate
I ==> HgS ==> mercury sulfide
I ==> Na₂S ==> sodium sulfide
A ==> HF ==> hydrofluoric acid
I ==> KCN ==> potassium cyanide

7.Are there hidden questions? What are they?
8.What operations will use to solve the problem?
9.What is the solution yo the problem?
10.How will you check if your answer makes sense?
Answer: See explanation
Explanation:
Annalyn weighs 45.3 kg.
Roby is 2.56 kg lighter than Annalyn. This means that the weight of Roby will be:
= 45.3kg - 2.56kg
= 42.74kg
Together with Cecille, the three of them weigh 150.09 kg. Cecille weight will be:
45.3kg + 42.74kg + Cecille = 150.09kg
88.04kg + Cecille = 150.09kg
Cecille = 150.09kg - 88.04kg
Cecille weight = 62.05kg
To check of my answer is correct, I'll add all their ages together. This will be:
= 45.3kg + 42.74kg + 62.05kg
= 150.09kg
How many oxygen atoms are there in 98.4g of oxygen gas. Hint: oxygen gas just might be diatomic! Be warned that on a test you will NOT be told if an element is diatomic. You need to memorize the diatomic elements.
Answer:
3.702×10^24 atoms of Oxygen.
Total, 6.15 moles of oxygen atoms in 98.4g of oxygen gas (O₂), which is equivalent to 6.15 × 6.022 × 10²³ (Avogadro's number) oxygen atoms.
Oxygen gas (O₂) is indeed diatomic, meaning it exists as a molecule with two oxygen atoms bonded together.
To calculate the number of oxygen atoms in 98.4g of oxygen gas (O₂), we need to use the molar mass of oxygen and the given mass.
The molar mass of oxygen (O₂) will be 32.00 g/mol.
Number of moles of oxygen gas = Mass (g) / Molar mass (g/mol)
Number of moles of oxygen gas = 98.4 g / 32.00 g/mol
≈ 3.075 moles
Since each molecule of oxygen gas (O₂) contains two oxygen atoms, the number of oxygen atoms will be twice the number of moles of oxygen gas.
Number of oxygen atoms = 2 × Number of moles of oxygen gas
Number of oxygen atoms ≈ 2 × 3.075 moles
≈ 6.15 moles
Therefore, there are approximately 6.15 moles of oxygen atoms in 98.4g of oxygen gas (O₂), which is equivalent to 6.15 × 6.022 × 10²³ (Avogadro's number) oxygen atoms.
