Explanation:
1. Synthesis Reaction: In this type of reaction multiple reactant combine to form a single product.
2. Decomposition Reaction: In this type of reaction single compound or reactant break down into new elements or compounds.
3. Replacement Reaction: In this type of reaction an element replace an element in a compound.
4. Even hydrogen is not a metal but it can act as metal in single replacement reaction.
5. In combustion reaction fuel react with oxygen and give heat and light that increase temperature of surrounding.
6. In in-complete combustion reaction fuel react with in-sufficient oxygen and give carbon monoxide and carbon in form of soot.
7. Base is a compound that liberate OH⁻ ion in water.
8. indicators have different color in acid and base depends on pH of the solution
9. Salt and water are the product of neutralization reaction
NaOH + HCl = NaCl + H₂O
10. The pH of neutral solution is 7.
Answer:
The volume will be 0.031 L
Explanation:
Since temperature is constant, Boyle's law is applied in this case.
Boyle's law States that at constant temperature, the volume of a given mass of a gas is inversely proportional to it's pressure.
From this statement it was deduced that P1V1 = P2V2
From the question, P1 = 1atm, V1 = 1.55L, P2 = 50 atm and V2 is to be calculated.
V2 = P1V1/P2
= 1×1.55÷50
=0.031 L
2 Na + 2 H2O → 2 NaOH + H2 (balanced equation)
The answer would be 2, since 2 in the coefficient of both Na and NaOH
