The volume of a gas is 650.ml at 1.14celsius what will the volume be at 75.0 Celsius?
Triss [41]

Answer: 42763ml

Explanation:

Using Charle's law

V1/T1=V2/T2

V1= 650ml

V2=?

T1= 1.14c

T2= 75c

Substitute the value

650/1.14=V2/75

Cross multiply

650×75=V2×1.14

V2= 650×75/1.14

V2= 42763.16ml

V2= ~42763ml

Which best describes a reaction in a state of equilibrium?
tamaranim1 [39]

The best statement which describes a reaction in a state of equilibrium is letter D.  <span>The rate of the forward reaction equals the rate of the reverse reaction and the </span>concentrations of products and reactants are constant. 

>Chemical equilibrium<span> is defined as<span> the state in which both reactants and products are present in </span></span>concentrations<span> which have no further tendency to change with time. This state results when the forward reaction proceeds at the same rate as the </span>reverse reaction<span>. The </span>reaction rates<span> of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s).</span>
