When the volume of a gas is changed from __ mL to 852 mL, the temperature will change from 315 degrees C to 452 degrees C
The volume of a gas is changed from 691 mL to 852 mL, the temperature will change from 315 °C to 452°C.
WHAT IS CHARLES LAW:Charles law states that the volume of a given gas is directly proportional to the temperature given that the pressure remains constant.
The charles law equation is as follows:
V1/T1 = V2/T2
V1/588 = 852/725
588 × 852 = 725V1
500,976 = 725V1
V1 = 500976/725
V1 = 691mL
Therefore, the volume of a gas is changed from 691 mL to 852 mL, the temperature will change from 315 °C to 452°C.

Answer: 2Li+(aq) + SO42-(aq) + Ca2+(aq) + 2NO3-(aq) = 2Li+(aq) + 2NO3-(aq) + CaSO4(s)
Explanation:
Li2SO4 + Ca(NO3)2 → LiNO3 + CaSO4
Lithium Sulfate + Calcium Nitrate = Lithium Nitrate + Calcium Sulfate
Balanced:
Li2SO4 + Ca(NO3)2 → 2LiNO3 + CaSO4
Write the state for each molecule if as aqueous, solid or liquid. All nitrates are normally soluble and sulfates are also soluble with few exceptions which are partially soluble.
2Li+(aq) + SO42-(aq) + Ca2+(aq) + 2NO3-(aq) = 2Li+(aq) + 2NO3-(aq) + CaSO4(s)
1. A 35.3 g of element M is reacted with nitrogen to produce 43.5 g of compound M3N2 What is (i) the molar mass of the element and (ii) name of the element?
1. The molar mass of the element M is 40 g/mol
2. The name of the element is calcium (Ca)
Description of mole
The mole an element is related to it's mass and molar mass according to the following equation:
Mole = mass / molar mass
How to determine the mass of nitrogen Mass of M = 35.3 gMass of compound = 43.5 gMass of nitrogen =?Mass of nitrogen = 43.5 – 35.3
Mass of nitrogen = 8.2 g
1. How to determine the molar mass of MMass of nitrogen = 8.2 gMolar mass of nitrogen = 14 g/mol Formula of compound = M₃N₂Mole ratio of M to nitrogen = 3 : 2Mass of M = 35.3 gMolar mass of M = y =?Mole of M : Mole of nitrogen = 3 : 2
35.3 / y ÷ 8.2 / 14 = 3 : 2
(35.3 / y) × (14 / 8.2) = 3 / 2
494.2 / 8.2y = 3 / 2
Cross multiply
8.2y × 3 = 494.2 × 2
24.6y = 988.4
Divide both side by 24.6
y = 988.4 / 24.6
y ≈ 40 g/mol
Thus, the molar mass of the element is 40 g/mol
2. How to determine the name of the element Molar mass of element = 40 g/mol Name of element =?From the periodic table, the element having a mass number of 40 is Argon and Calcium. Since argon will not react with nitrogen to produce Ar₃N₂.
Therefore, we can conclude that the element is calcium since it can react with nitrogen as illustrated by the equation
3Ca + N₂ —> Ca₃N₂

Purchasing the correctly sized BMX bike is based on the height of the rider. In order to fit a customer, the salesman can use the equation b=0.29h+1.35 where b is the size of the BMX bike frame in inches and h is the height of the rider in inches.
1. As a rider increases one inch in height, the bike frame increases 0.29 inches.
2. The height of the rider gets multiplied by 0.29.
3. The bike frame increases 0.29 inches for every 1.35 inches of the rider's height.
4. As a rider's height increases 1.35 inches, the bike frame increases one inch.

The property of the gas that was used by the chemist's report is volume. The correct option is D.
What is volume?
Volume is a scalar quantity that is used to measure the space occupied by a three-dimensional object. In terms of liquid and gas, the volume is measured as the capacity of the container that contains a liquid.
Gas is a state of matter that has no regular shape and no fixed volume. They have the lowest density and their moles are farthest from each other.
Gallon is a unity of volume that is used in the metric system of the United States. There are 100 gallons of gas in the container, the volume of gas is the total number of moles of the gas in a container.
Thus, the correct option is D. Volume.

A student correctly determines that 17.1 grams of sucrose are needed to make 50 ml of a 1m sucrose solution. when making the solution in the lab, the student measured 50ml of solution and then adds the 17.1 grams of sucrose to the beaker. the student’s resulting solution was not 1m as intended. after the student mixed the solution, the resulting solution was measured at 62ml.
The initial and final molarity are 0.860 molars and 0.694 molars, respectively.
How to calculate molarity in a solution
In chemistry, molarity ([tex]M[/tex]), in molars, is described by the following expression:
[tex]M = \frac{n}{V}[/tex] (1)
Where:
[tex]n[/tex] - Molar amount of the solute, in moles[tex]V[/tex] - Volume of the solution, in litersThe molar amount of the solute is determined by this formula:
[tex]n = \frac{m}{M}[/tex] (2)
Where:
[tex]m[/tex] - Mass of the solute, in grams[tex]M[/tex] - Molar mass, in moles per gramsIf we know that [tex]m = 17.1\,g[/tex], [tex]M = 397.64\,\frac{g}{mol}[/tex], [tex]V_{1} = 0.050\,L[/tex] and [tex]V_{2} = 0.062\,L[/tex], then the initial and final molarities are, respectively:
[tex]n = \frac{17.1\,g}{397.64\,\frac{g}{mol} }[/tex]
[tex]n = 0.043\,mol[/tex]
Initial molarity[tex]M_{1} = \frac{0.043\,mol}{0.050\,L}[/tex]
[tex]M_{1} = 0.860\,M[/tex]
Final molarity[tex]M_{2} = \frac{0.043\,mol}{0.062\,L}[/tex]
[tex]M_{2} = 0.694\,M[/tex]
