Answer: The law that illustrates this is Boyle's Law

Explanation:

Boyle's law: This law states that pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

Mathematically,

$P\propto \frac{1}{V}$ (at constant temperature and number of moles)

Charles' law: This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

Mathematically,

$V\propto T$ (at constant pressure and number of moles)

Avogadro's law: This law states that volume of the gas is directly proportional to the number of moles of the gas at constant pressure and temperature.

Mathematically,

$V\propto n$ (at constant pressure and temperature)

So, when the volume of the air in the gun decreases, the pressure is increased. The inverse relationship between the volume and pressure of the gas is very well illustrated by Boyle's Law.

Hence, the law that illustrates this is Boyle's Law

An extremely soluble salt is added to water, and all of it dissolves. Is it at equilibrium? Explain.

alexdok [17]

Once the substance stops dissolving, the system is at equlibrium with the water and the undissolved salt now, if it is in the process of dissolving because it is completely soluble but has not been able to completely dissolve, it is not at equilibrium

Tim is grilling burgers for dinner. He uses 15.0g of propane. Given that the combustion of propane releases 2,220 kJ/mol and tha

Gwar [14]

Answer:

Heat Enthalpy used = 755 Kilojoules

Explanation:

15 grams propane = (15g/44.097g·mol⁻¹) = 0.3402mol propane

Heat Enthalpy used = 0.3402mol X 2,220Kj/mol = 755 Kilojoules

When the following equation is balanced, what is the lowest whole-number coefficient for SO2? ____ HBrO3(aq) + ____ SO2(g) + ___

lakkis [162]

Answer : The lowest whole-number coefficient for $SO_2$ is, 5

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

The given unbalanced chemical reaction is,

$HBrO_3(aq)+SO_2(g)+H_2O(l)\rightarrow Br_2(aq)+H_2SO_4(aq)$

This reaction is an unbalanced chemical reaction because in this reaction number of hydrogen, bromine and oxygen atoms are not balanced.

In order to balance the chemical equation, the coefficient '2' put before the $HBrO_3$ , the coefficient '5' put before the $SO_2\text{ and }H_2SO_4$ and the coefficient '4' put before the $H_2O$ and we get the balanced chemical equation.

The balanced chemical reaction will be,

$2HBrO_3(aq)+5SO_2(g)+4H_2O(l)\rightarrow Br_2(aq)+5H_2SO_4(aq)$

Thus, the lowest whole-number coefficient for $SO_2$ is, 5

Sodium permanganate and iron(III) chloride are both dissolved in a beaker of water. In a double displacement reaction, two new p

Nastasia [14]

Answer: The balanced chemical equation is written below.

Explanation:

Double displacement reaction is defined as the reaction in which exchange of ions takes place.

$AB+CD\rightarrow CB+AD$

When sodium permanganate reacts with iron (III) chloride, it leads to the production of sodium chloride and iron (III) permanganate.

The chemical equation for the reaction of sodium permanganate and iron (III) chloride follows:

$3NaMnO_4(aq.)+FeCl_3(aq.)\rightarrow Fe(MnO_4)_3(s)+3NaCl(aq.)$

By Stoichiometry of the reaction:

3 moles of aqueous solution of sodium permanganate reacts with 1 mole of aqueous solution of iron (III) chloride to produce 1 mole of solid iron permanganate and 3 moles of aqueous solution of sodium chloride

Hence, the balanced chemical equation is written above.
