Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question we have

We have the final answer as
<h3>6.93 cm³</h3>
Hope this helps you
Br2 is the correct answer
B) 40%
The balanced equation indicates that for every 3 moles of H2 used, 2 moles of NH3 will be produced. So the reaction if it had 100% yield would produce (2.00 / 3) * 2 = 1.333333333 moles of NH3. But only 0.54 moles were produced. So the percent yield is 0.54 / 1.3333 = 0.405 = 40.5%. This is a close enough match to option "b" to be considered correct.
A substance that consist of two elements is one IN WHICH THE ELEMENTS ARE CHEMICALLY COMBINED IN A FIXED PROPORTION.
A compound is a substance that is made up of two or more elements which have undergone chemical reaction together and their individual properties have been lost during the reaction, thus a compound has properties that are different from those of its constituents elements. Compounds are usually combined in specific fixed ratio.<span />
90 degrees
As temperature increases, rate of reaction increases :)
