For the reaction 2hbr(g)⇌h2(g)+br2(g), k= 2.00×10−19 at 298 k what can be said about this reaction at this temperature? hints fo
Olin [163]

The equilibrium constant k is actually the ratio of the concentration of the products over the concentration of reactants at equilibrium. So if the concentration of products < concentration of reactants, therefore the constant k will be small. But if the concentration of products > concentration of reactants, the constant k will be large. In this case the value is too small (x10^-19), therefore we can say that the reaction favors the reactant side:

 

the equilibrium lies far to the left

A block has a mass of 25 grams and a volume of 24.5 cm3 what is the<br> density of the block?
schepotkina [342]

Answer:

<h3>The answer is 1.02 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass of block = 25 g

volume = 24.5 cm³

The density of the block is

density =  \frac{25}{24.5}  \\  = 1.020408163...

We have the final answer as

<h3>1.02 g/cm³</h3>

Hope this helps you
