WHat's a concept map again?
I forgot...
Answer:
Explanation:
B because it has a lower activation energy
Answer:
HNO3 and NaOH
Explanation:
A neutralization reaction is a reaction that occurs between an acid and a base to form salt and water only.
Neutralization reactions are commonly carried out by method of titration. That is, a measured volume of acid of unknown concentration is made to react with a known volume of standard base solution or vice versa.
Two reactants that could be titrated to obtain sodium nitrate are nitric acid and sodium hydroxide.
The reaction equation is as follows;
HNO3(aq) + NaOH(aq) ----> NaNO3(aq) + H2O
Answer:
930 g
Explanation:
D = m/V Multiply both sides by V
m = VD
<em>Data:
</em>
V = 372 cm³
D = 2.70 g/cm³
<em>Calculation:
</em>
m = 372 × 2.50
m = 930 g
The mass of Al is 930 g.
