Answer:
Heat required to melt 26.0 g of ice at its melting point is 8.66 kJ.
Explanation:
Number of moles of water in 26 g of water: 26×
moles
=1.44 moles
The enthalpy change for melting ice is called the entlaphy of fusion. Its value is 6.02 kj/mol.
we have relation as:
q = n × ΔH
where:
q = heat
n = moles
Δ
H = enthalpy
So calculating we get,
q= 1.44*6.02 kJ
q= 8.66 kJ
We require 8.66 kJ of energy to melt 26g of ice.
Answer:
It is the total distance traveled over the total time .
<span>The chemical reaction of a reversible reaction is actually
governed by Le Chatelier’s principle. It states that when more reactants are
introduced into the system, the reaction will proceed forward to create more
products. So since Hydrogen is a reactant and Nitrogen is also reactant so
adding more Hydrogen makes more products hence reducing the Nitrogen
concentration.</span>
Turning things to gram so need to convert to the metric system
Magnesium + Hydrocloric acid -> Magnesium chloride + hydrogen
You can observe a single displacement reaction
"Describe to show that the has formed is hydrogen"
I don't know what you mean. I can show the chemical equation though.
Mg(s) + 2 HCl(aq) --> MgCl 2(aq) + H 2(g)
