<u>Explanation:</u>

Hydrocarbons are defined as organic compounds which are only made from carbon and hydrogen atoms.

There are mainly 3 types of hydrocarbons:

Alkanes are the type of hydrocarbons where a single bond is present between the carbon atoms. The general formula for these is $C_nH_{2n+2}$ , where 'n' is the number of carbon atoms.

Alkenes are the type of hydrocarbons where at least one double bond is present between the carbon atoms. The general formula for these is $C_nH_{2n}$ , where 'n' is the number of carbon atoms.
Alkynes are the type of hydrocarbons where at least one triple bond is present between the carbon atoms. The general formula for these is [tex]C_nH_{2n-2}, where 'n' is the number of carbon atoms.

The addition of an inert gas has no effect on the equilibrium position of a gaseous reaction because ______. Multiple choice que

boyakko [2]

Inert gas does not affect the equilibrium position:

It is because the partial pressures of the reaction components remain the same.

What is Inert Gas?

Under a given set of conditions, an inert gas is a gas that does not undergo chemical reactions.
The noble gases (helium, neon, argon, krypton, xenon, and radon) were previously known as "inert gases" due to their perceived lack of involvement in any biochemical processes.
Because inert gases are non-reactive, they do not affect equilibrium partial pressures and thus do not affect volume.
An inert gas does not react with the reactants or products; it does not change the concentration of the products and reactants. Furthermore, because the volume is constant, the concentrations are unaffected. As a result, this does not affect equilibrium.

The equilibrium position won't change if an inert gas is added. A volume change won't change the equilibrium position if the total moles of gas in the products and reactants are the same. When the volume is reduced, the process changes to create fewer moles of gas.

Chlorine gas reacts with aluminum metal producing aluminum chloride. What mass of chlorine reacts with 9.00g of Al to form AlCl3

Anit [1.1K]

The mass of chlorine that react with 9.00 g of Al to form AlCl3 is 35.465 grams

Explanation
write the equation for reaction
that is
2 Al + 3 Cl2 = 2 Al CL3
find the moles of Al reacted

moles = mass/molar mass

9 g/ 27 g/mol = 0.333 moles of Al

by use of mole ratio between Al to Cl2 which is 2:3 find the moles of Cl2

mole of cl2 = 0.333 x3/2 = 0.4995 moles

mass of Cl2 is therefore = moles x molar mass

= 0.4995 x71 = 35.465 moles

g Ethanol boils at 78.4 °C with \DeltaΔHvap = 38.6 kJ/mol. A 0.200-mol sample of ethanol is heated from some colder temperature

andrezito [222]

Answer:

8.77 kilo Joules will be the total amount of heat required for both the heating and the vaporizing.

Explanation:

Moles of ethanol of ethanol = 0.200 mol

Heat required to heat 0.200 moles of ethanol = Q = 1.05 kJ

Enthalpy of vaporization of ethanol = $\Delta H_{vap}=38.6 kJ/mol$

Heat required to vaporize 0.200 moles of ethanol = Q'

$Q'=\Delta H_{vap}\times 0.200 mol=38.6 kJ/mol\times 0.200 mol=7.72 kJ$

Total heat required to fore heating and the vaporizing :

= Q + Q' = 1.05 kJ + 7.72 kJ = 8.77 kJ

8.77 kilo Joules will be the total amount of heat required for both the heating and the vaporizing.
