how much energy is required to change 110 grams of steam at 181 C to 40 C
Answers
Answer:
Q = -64893.84 J
Explanation:
Given data:
Mass of steam = 110 g
Initial temperature = 181 °C
Final temperature = 40°C
Energy released = ?
Solution:
Energy will released in this process because temperature is going to be decreased.
Specific heat capacity of water is 4.184 J/g.°C
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 40°C - 181 °C
ΔT = -141°C
Q = 110 g × 4.184 J/g.°C × -141°C
Q = -64893.84 J

Volatility and vapor pressure are ________. Volatility and vapor pressure are ________. not related directly proportional to one another both independent of temperature the same thing inversely proportional to one another
Answers
Answer:
directly proportional to one another
Explanation:
Volatility refers to how quickly a substance changes from liquid to gas.
If a substance has a high vapour pressure, the substance is highly volatile. Similarly, if a substance has a low vapour pressure, then the substance is much less volatile.
This implies that volatility and vapour pressure gives a direct proportionality.

Answer:
S - waves
Explanation:
Secondary s-waves are elastic waves and they are part of the earliest waves that reach are seismic station.
Both P and S -waves are the first set of waves to reach a seismic station after an earthquake event.
P waves are primary waves and they move through any kind of earth materials. They transmitted longitudinally. S - waves are secondary waves. These waves are shear waves and they cannot be propagated through liquids.Can someone help me please I’m giving the brainliest

Write the information obtained from solubility curves.
Answers
Explanation:
The solubility curve helps us to compare the solubility of difference substances at same temperature. It gives the idea that solubility changes with the temperature. The solubility curve helps us to predict which substance will crystalize out first from hot solution containing two or more solutes.

Explanation:
which period of the periodic table is completely made up of elements with no known stable ions?
Answers
Answer:
I think the answer is period 7
Explanation:
The period in periodic table, in which no stable ions of elements exists is 7th period. They contains actinides.
What are actinides?Actinides are 7th period elements classified to F block of periodic table. A periodic table contains vertical columns called groups and horizontal rows called periods. Each elements are classified into suitable groups based on their similarity in properties with other group elements.
There are four blocks in periodic table which are s, p, d and f block. S block elements are metals and d block contains transition metals and p block have non metals including gases and metalloids.
Actinides are f- block metals. All the elements in the period are radioactive. That's why they don't have a stable isotope or ion. They continuously undergo radioactive decay by the emission of charged particles.
Hence, the period containing unstable elements is 7th one.

21. Why are radioactive nuclei unstable?
a. There is not the proper neutron to proton ratio resulting in a stable nucleus
b. There is too much energy stored in the bonds between atoms
C. They need to gain/lose electrons to have a full valence energy level
d. Protons reverse their charges and begin to repel one another
Answers
Answer:
a. There is not the proper neutron to proton ratio resulting in a stable nucleus
Explanation:
Radioactive nuclei are unstable because they do not have a proper neutron to proton ration that can result in a stable nucleus for them.
Every atomic nucleus has specific neutron to proton ratio. The ratio ensures the stability of the nucleus. Any nucleus with a neutron/proton combination different from its stability ratio will be unstable and split into one or more other nuclei. This is usually with an attendant emission of small particles of matter and electromagnetic ionizing radiation and energy.A 1.5 M solution of NaOH was made in a laboratory. If the solution made had a volume of 4.5 L, how many grams of NaOH were added?
Answers
Answer:
270g
Explanation:
Given parameters:
Concentration of solution = 1.5M
Volume of solution = 4.5L
Unknown:
Mass of NaOH added = ?
Solution:
Concentration is the number of moles of solute found in a solution.
To solve this problem, we need to find the number of moles of NaOH first;
Number of moles = concentration x volume
Number of moles = 1.5 x 4.5 = 6.75moles
Now, to find the mass of NaOH;
Mass of NaOH = number of moles x molar mass
Molar mass of NaOH = 23 + 16 + 1 = 40g
Mass of NaOH = 6.75 x 40 = 270g
