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.
Answers
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

A chemical process used to produce ethanol as a fuel additive was expected to produce 5,000 kilograms of ethanol based on the amounts of starting materials used, but only 4,760 kilograms were produced. What was the percent yield for ethanol in this process?
A)1.09
B)4.80
C)95.2
D)105
Answers
Answer:
C)95.2
Explanation:
Given parameters:
Expected yield = 5000kg
Experimental yield = 4760kg
Unknown:
Percentage yield = ?
Solution:
The percentage yield of the substance is determined by find the ratio of the true experimental yield to the expect yield and multiply by 100;
Percentage yield = [tex]\frac{4760}{5000}[/tex] x 100 = 95.2%

C. contain one molecule each
D. have the same mass
Answers
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.

List four rules for rounding numbers.
Answers
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.

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?
Answers
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
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
Answers
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.

How many grams of NH3 can be dissolved in 50 grams of water at 50oC?
Answers
15 grams of NH3 can be dissolved
Further explanationGiven
50 grams of water at 50°C
Required
mass of NH3
Solution
Solubility is the maximum amount of a substance that can dissolve in some solvents. Factors that affect solubility
1. Temperature: 2. Surface area: 3. Solvent type: 4. Stirring process:We can use solubility chart (attached) to determine the solubility of NH3 at 50°C
From the graph, we can see that the solubility of NH3 in 100 g of water at 50 C is 30 g
So that the solubility in 50 grams of water is:
= 50/100 x 30
= 15 grams
