what happens to some of the electrons in an atom when the atom is heated
Answer:
When the electrons in the atom are excited, for example by being heated, the additional energy pushes the electrons to higher energy orbitals. When the electrons fall back down and leave the excited state, energy is re-emitted in the form of a photon

How many kilograms of phosphorous are in a sample containing 1.00E31 phosphorous atoms?
Answer: [tex]5.15\times 10^5kg[/tex]
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number of particles.
To calculate the number of moles, we use the equation:
Putting in the values we get:
[tex]\text{Number of moles}=\frac{1.00\times 10^{31}}{6.023\times 10^{23}}=0.166\times 10^{8}moles[/tex]
1 mole of phosphorous [tex]P[/tex] weighs = 31 g
Thus [tex]0.166\times 10^8[/tex] moles of phosphorous [tex]P[/tex] weigh=[tex]\frac{31}{1}\times 0.166\times 10^8=5.15\times 10^8g=5.15\times 10^5kg[/tex]
A student performed a similar experiment we have done, with Ag and O to produce silver oxide.
Mass of crucible and lid: 29.307 g
Mass of crucible, lid, and silver: 30.958 g
Mass of crucible, lid, and silver oxide: 31.080 g
Use the above data to calculate the moles of the metal used in this experiment. your answer must include correct significant figures and unit.
Answer:
0.0153 mol
Explanation:
Mass of crucible and lid: 29.307 g
Mass of crucible, lid, and silver: 30.958 g
Number of moles = Mass /Molar mass
Mass of Silver = Mass of crucible, lid, and silver - Mass of crucible and lid
Mass of siilver = 30.958 g - 29.307 g
Mass of silver = 1.651 g
Molar mass of silver = 107.868 g/mol
Number of moles = 1.651 g / 107.868 g/mol
Number of moles = 0.0153 mol

explain the variation of basicity in group III A members down the group
Answer:
Explained below
Explanation:
Group 3A elements are made up of the metalloid - boron (B) and other metals such as Aluminum (Al), gallium (Ga), indium (In), & thallium (Tl).
Now, as we go down the group, the size of the central atom will increase thereby causing the lone pair to become delocalized over a larger volume space. Thus, it's not readily available for donation and thus basicity increases

The bond angles around a carbon in a
triple bond are

A. 180, sp?
B. 120, sp
C. 180, sp
D. 120, sp?
Enter
The bond angles around carbon in the triple bond are 180 degrees and it is sp hybridized. option B is correct
What is sp hybridization?This hybridization process involves mixing the valence s orbital with one of the valence p orbitals to yield two equivalent sp hybrid orbitals that are oriented in a linear geometry.
The set of sp orbitals appears similar in shape to the original p orbital, but there is an important difference. The number of atomic orbitals combined always equals the number of hybrid orbitals formed.
The p orbital is one orbital that can hold up to two electrons. The sp set is two equivalent orbitals that point 120° from each other. The two electrons that were originally in the s orbital are now distributed to the two sp orbitals, which are half filled.
Therefore, due to the sp hybrid and 120-degree angle option B is correct

Given the following balanced equation, determine the rate of reaction with respect to [SO3]. If the rate of O2 loss is 3.56 x 10-3 M/s, what is the rate of formation of SO3?
Answer:
7.12 × 10⁻³ M/s
Explanation:
Step 1: Write the balanced reaction
2 SO₂ + O₂ ⇒ 2 SO₃
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of O₂ to SO₃ is 1:2.
Step 3: Calculate the rate of formation of SO₃
The rate of loss of O₂ is 3.56 × 10⁻³ mol O₂/L.s. The rate of formation of SO₃ is:
3.56 × 10⁻³ mol O₂/L.s. × 2 mol SO₃/1 mol O₂ = 7.12 × 10⁻³ mol SO₃/L.s

In an investigation, the volume of a material is measured
as 80.0 cm3 and its mass is measured as 253 g. Which
calculation of density correctly uses the precision rules:
3.1625 g/cm3, 3.163 g/cm3, 3.16 g/cm3, 3.2 g/cm3, or 3
g/cm3?
Answer:
3.2 g/cm3
Explanation:
Mass = 253 g
Volume = 80.0 cm3
Density = Mass / Volume = 253 g / 80.0 cm3
Density = 3.1625 g/cm3
The precision rule means the answer must not have more significant values than the value with the least number of significant figures. In this case, the value with the least number of significant figures is 80.0 with two signiificant figures. Hence;
Answer = 3.2 g/cm3

what is the volume, in liters, of 5.500 mol of C3H3 gas at STP
Answer:
123.2 Liters.
Explanation:
At STP (T = 273K & P = 1atm), one mol of any gas will occupy 22.4 liters.
With the above information in mind, we can calculate how many liters would 5.500 mol of gas occupy:
5.500 mol * 22.4 L / mol = 123.2 L
So 5.500 moles of C₃H₃ would have a volume of 123.2 liters at STP.

Each person in a room is assumed to be producing carbon dioxide at the average rate of 0.0107 cfm (5.0 ml/s) and air with a CO2 concentration of 280 ppm is being supplied to the room at the rate of 6000 cfm (2.8 m3/s). It is desired to keep the concentration level of CO2 in the space below 1000 ppm. Assuming complete mixing, determine how many persons could occupy the room and not exceed the desired CO2 level.
Answer:
404 persons
Explanation:
To get n= number of persons
We use this formula
n = I(Dc - EaC)Eaf
I = 6000 = inflow rate
Dc = desired concentration = 1000
Eac = Exhaled air concentration = 280ppm = 0.00028
Exhaled air flow rate = Eaf = 0.0107
When we put values into the formula above
6000(0.001-0.00028)/0.0107
= 6000(0.00072)/0.0107
= 4.32/0.0107
= 403.7
