If 10.0 L of nitrogen gas reacts with 16.0 L of hydrogen gas, how many liters of ammonia gas (NH3) will be
produced?
Volume of ammonia gas : 10.67 L
Further explanationGiven
10.0 L of nitrogen gas
16.0 L of hydrogen gas
Required
Volume of ammonia gas
Solution
Reaction
N₂ + 3H₂ ⇒ 2NH₃
From Avogadro's hypothesis, at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles
Find limiting reactant :
N₂ : 10 : 1 = 10
H₂ : 16 : 3 = 5.3
H₂ as a limiting reactant
So volume of NH₃ based on H₂
= 2/3 x volume H₂
= 2/3 x 16 L
= 10.67 L

A mole of Br2 and a mole of CH2Br2
Select one:
A. have a mass of 1g each
B. contain the same number of molecules
C. contain one molecule each
D. have the same mass
The term mole is defined as the amount of substance of a system which contains as many elementary entities. A mole of Br₂ and a mole of CH₂Br₂ have a mass of 1g each. Therefore, option A is correct.
What do you mean by mole ?The term mole is defined as the amount of substance of a system which contains as many elementary entities.
1 mole is equal to 6.023 × 10 ²³ molecules.
One mole of any substance is equal to 6.023 × 10²³ units of that substance such as atoms, molecules, or ions. The number 6.023 × 10²³ is called as Avogadro's number or Avogadro's constant.
The mole concept can be used to convert between mass and number of particles.
A mole of Br₂ and a mole of CH₂Br₂ have a mass of 1g each. Because one mole of substance is equal to 6.023 × 10 ²³ molecules.
Thus, option A is correct.

A gas that exerts a pressure of
15.6 psi in a container with a volume of
L will exert a
pressure
of
25.43 psi when transferred to a
container with a volume of 1.895 L.
Answer:
V1 = 3.09 L
Explanation:
Initial Pressure, P1 = 15.6 psi
Initial Volume, V1 = ?
Final Pressure, P2 = 25.43 psi
Final Volume, V2 = 1.895 L
The relationship between these quantities is given by boyles law;
V1P1 = V2P2
V1 = V2P2 / P1 = 1.895 * 25.43 / 15.6
V1 = 3.09 L

Element X has three electrons in its outermost orbit.
Element Y has seven electrons in its outermost orbit.
What is the chemical formula of the ionic compound
formed by these elements when they react together?
(Use X and Y as the chemical symbols.)
Answer:
A has 3 electrons in outermost orbit and B has 6 electrons in its outermost orbits. So A can give three electrons to complete its octet and B need 2 electrons to complete its octet. so 2 atoms of A will release 6 electrons and 3 atoms of B will need six electrons to complete their octet So, the formula will be A2 B3.
The chemical formula of the ionic compound formed by these elements when they react together is X₂⁺Y₃⁻.
What is the chemical formula?A compound's makeup is symbolically represented by its chemical formula. It contains charges, ions, etc.
X has 3 electrons in its furthest outer orbit, while Y has 6 electrons there. In order to complete its octet, X can contribute three electrons, but Y requires two electrons.
So, three atoms of Y will require six electrons to complete their octet, while two atoms of X will release six electrons.
Here, the chemical formula is X₂⁺Y₃⁻, as X is donating an electron so it will gain a positive charge, and Y is gaining an electron, so it will gain a negative charge.
Thus, the chemical formula of the ionic compound is X₂⁺Y₃⁻.

What rule/principle States that electrons fill orbital from lowest energy to highest energy?
A: Aufbau principle
B: Hund's rule
C: Pauli exclusion principle
The orbital filling and electron configuration are based on various principles. The Aufbau principle states that electrons fill the orbital from lowest to highest energy levels. Thus, option A is correct.
What is the Aufbau principle?The Aufbau principle is the rule that states about the filling of the electron in the various orbitals of an atom. It defines the filling of the lower atomic orbitals before the higher levels are filled.
This principle allows for determining the electronic configuration of the atom. The rule states that the electron first occupies the lowest energetically unrestricted orbits that can hold a certain number of electrons. The electron can only move to a higher level when the electron is filled in the previous subshell.
Therefore, option A. the Aufbau principle gave the filling of electrons in the lowest energy level.

volume = 22.4 L
1.0 mol of nitrogen and 2.0 mol of hydrogen at 0°C
Required
Total pressure and partial pressure
Solution
Ideal gas law :
PV = nRT
n total = 3 mol
T = O °C + 273 = 273 K
P = nRT/V
P = 3 x 0.08205 x 273 / 22.4
P total = 3 atm = 303,975 kPa
P Nitrogen = 1/3 x 303.975 = 101.325 kPa
P Hydrogen = 2/3 x 303.975 = 202.65 kPa

List four rules for rounding numbers.
Answer:
the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30
Rounding fractions works exactly the same way as rounding whole numbers. The only difference is that instead of rounding to tens, hundreds, thousands, and so on, you round to tenths, hundredths, thousandths, and so on.
By rounding off, you could easily figure out that you would need about $6.00 to pay for your groceries.
