13 liters is the correct answer
13 liters is the final volume of the gas when the temperature and pressure remain constant.
v1/n1 = v2/n2
where,
v1 = initial volume = 8.5 liter
n1= initial mole of gas = 1.2 mole
n2= final mole of gas = 1.2+0.65= 1.85 mole
v2= final volume = ?
8.5 L/1.2 mol = v2/1.85 mol
7 L x 1.85 mol = v2/1.85 mol x 1.85 mol
13 L = v2
v2= 13 liter
<h3>What is a mole?</h3>
- A mole is an SI unit used to measure significant numbers of subatomic particles, such as atoms, molecules, or smaller particles.
- Any substance has an Avogadro number of molecules in a mole.
- The value of the Avogadro number is 6.02214076 × .
<h3>How much is a mole of gas?</h3>
22.4 L
At STP (Standard Temperature and Pressure = 0 °C, 1 atm), an ideal gas has a volume of 22.41 L/mol.
<h3>What makes something a mole?</h3>
- Chemists use the term "mole" because atoms, molecules, and other particles are all very small and require a large amount to even weigh them.
- A mole is a measurement of the number of particles present, not their mass.

Answer : The limiting reactant is, carbon (C)
Explanation : Given,
Moles of = 2 moles
Moles of C = 5 moles
Now we have to calculate the limiting and excess reagent.
The given balanced chemical reaction is:
From the balanced reaction we conclude that
As, 3 mole of react with 1 mole of
So, 5 moles of react with moles of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.
Thus, the limiting reactant is, carbon (C)
VESPR (<span>Valence Shell Electron Pair Repulsion) is used to determine the shape of the molecules based on their number of electron pairs and how they interact with each other via repulsion. Different numver of electron pairs will form different shapes, e.g. 0 pairs = linear, 1 = pyramidal...</span>
Answer:
All of the following statements are true regarding wood versus metal except:
c) Under sustained loads wood stops to deform
Explanation:
Wood is known to deform under stress. It undergoes warping, thereby, losing its original straight shape when its moisture unevenly dries up. Even concrete deforms under long-time loads. Similarly, wood, under sustained loads, experiences faster deformation than it ordinarily warps. To prevent further wood deformation, it must be treated, and its moisture dried up evenly.
Answer: 225 joules.
Explanation:
If this a one dimension problem, this is the motion is in the same direction of the force, the equation for work is:
Work = distance × force
⇒ Work = 15 m × 15 N = 225 joules.
This is a special case of the general equation
Work = |F| |displacement| cosine (angle between the force and displacement)
When force and displacement are in the same direction, the angle is 0, so cos(0) = 1. This is the two vectors are parellel and the work is just the product of the two magnitudes (force and distance)
