This question uses mole ratios. firstly, we look at how many moles of H2 are produced for every mole of HCl: from 1 Hcl, we get half a mole of H2. therefore, however many moles of HCl are present in the 0.075 L of 1.0M HCl, half that number of H2 moles will be produced.
n=cv
=0.0750 x 1.0
=0.075 mol HCl
n(H2)= 0.5 x n(HCl)
=0.0375 moles of H2
Answer:
Nickel
Explanation:
This element and its alloys are used in pumps, valves, and other components that are in contact with acid and petroleum solutions
Answer:
<span>The energy involved in endothermic and exothermic reactions is Heat.
Explanation:
In Endothermic Reactions the energy required to break the bonds is greater than the amount of energy released on bond formation. This required excess energy is absorbed from surrounding in the form of heat. Hence, the temperature of surrounding drops.
While, </span>In Exothermic Reactions the energy required to break the bonds is less than the amount of energy released on bond formation. This excess energy is released to the surrounding in the form of heat. Hence, the temperature of surrounding rises.
