V1= 19.229L

Explanation:

V1/T1 = k

V1/836.06=14.509/625.06

V1/836.06= 0.023

V1 = 19.229L

The temperature of CI₂ is changed from 836.06K to 625.06K. If it's new volume is 14.509L then its original volume in liters was 19.4 L.

The combined gas law is the law of of gaseous state which is made by combination of Boyle's law, Charle's law, Avogadro's law and Gay Lussac's law.

It is a mathematical expression that relates Pressure, Volume and Temperature.

(P1 × V1)÷T1 = (P2 × V2)÷T2

We can also use the following relation-

PV = nRT

According to the question, Pressure is constant and we can write the formula as-

V1÷T1 = V2÷T2

T1 = 836.06 K

T2 = 625.06 K

V1 = ?

V2 = 14.509 L

V1 = 19.4 L

Therefore, The temperature of CI₂ is changed from 836.06K to 625.06K. If it's new volume is 14.509L then its original volume in liters was 19.4 L.

Answer:

Potassium will donate an electron to bromine.

Explanation:

When potassium and bromine come together, the more electronegative bromine will snatch that solitary valence electron from the potassium atom. This will lead to the formation of the potassium cation, K+ , and the bromide anion, Br− .

Answer: Silver has the highest temp. change and water has the lowest temp. change.

Explanation:

According to the specific heat capacity, water  has lowest specific heat and greatest is that of silver owing to their temperature differences.

Specific heat capacity is defined as the amount of energy required to raise the temperature of one gram of substance by one degree Celsius. It has units of calories or joules per gram per degree Celsius.

It varies with temperature and is different for each state of matter. Water in the liquid form has the highest specific heat capacity among all common substances .Specific heat capacity of a substance is infinite as it undergoes phase transition ,it is highest for gases and can rise if the gas is allowed to expand.It is different for different substances.

Answer:

Fluid power systems perform work by a pressurized fluid bearing directly on a piston in a cylinder or in a fluid motor. A fluid cylinder produces a force resulting in linear motion, whereas a fluid motor produces torque resulting in rotary motion. Within a fluid power system, cylinders and motors (also called actuators) do the desired work. Control components such as valves regulate the system.

Explanation:

Based on the data given, the molar mass of the gas is 165.5 g/mol while the molecular weight of the gas is 165.5 amu

The molar mass of a gas can be obtained from density, temperature and pressure using the formula below:

Molar gas constant, R = R = 0.082 L.atm/mol/K.

Temperature = 150 °C = 423 K

Pressure = 785 torr = 1.033 atm

density = 4.93 g/L

molar mass of gas = 4.93 × 0.082 × 423/1.033

molar mass of gas = 165.5 g/mol

Then, molecular weight of the gas = 165.5 amu

Therefore, the molar mass of the gas is 165.5 g/mol while the molecular weight of the gas is 165.5 amu

First find the balanced equation for this rxn

C3H8    +  5O2    ====>     3 CO2    + 4  H2O

To calculate the atoms of an element in a given molecule, we need to multiply stoichiometry by the number that is written on the foot of that element. The correct option is option A.

Balanced equation is the one in which the total number of atoms of a species on reactant side is equal to the total number of atoms on product side. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, displacement reaction.

Propane gas, C[tex]_3[/tex]H[tex]_8[/tex], burns in excess oxygen gas. When the equation for this reaction is correctly balanced and all coefficients are reduced to their lowest whole-number terms, the coefficient for O[tex]_2[/tex] is 5.
