Answer:

answers are in attachment

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.

gThe mole fraction of potassium nitrate in an aqueous solution is 0.0194. The solution's density is 1.0627 g/mL. What is the mol
xxMikexx [17]

Answer:

0.595 M

Explanation:

The number of moles of water in 1L = 1000g/18g/mol = 55.6 moles of water.

Mole fraction = number of moles of KNO3/number of moles of KNO3 + number of moles of water

0.0194 = x/x + 55.6

0.0194(x + 55.6) = x

0.0194x + 1.08 = x

x - 0.0194x = 1.08

0.9806x= 1.08

x= 1.08/0.9806

x= 1.1 moles of KNO3

Mole fraction of water= 55.6/1.1 + 55.6 = 0.981

If

xA= mole fraction of solvent

xB= mole fraction of solute

nA= number of moles of solvent

nB = number of moles of solute

MA= molar mass of solvent

MB = molar mass of solute

d= density of solution

Molarity = xBd × 1000/xAMA ×xBMB

Molarity= 0.0194 × 1.0627 × 1000/0.981 × 18 × 0.0194×101

Molarity= 20.6/34.6

Molarity of KNO3= 0.595 M
