Answer : The correct option is, (C)
Explanation :
A. 
This is synthesis reaction in which the two or more reactant react to give a single product.
B. 
This is combination reaction in which the two reactants combine to form a single product.
C. 
This is a neutralization reaction in which an acid react with a base to give a salt and water as a product.
D. 
This is a double displacement reaction in which the positive cation and negative anion of two reactants exchange their places to give two new products.
Hence, the reaction (C) is a neutralization reaction.
Answer:
moles of water in 1 ml = 1/18 mol.
take 1 ml and calculate it by 30
1 ml x 30= 30 ml
Explanation:
Acid + base = water + salt
KOH + HCl = H₂<span>O + KCl

Answer:
- <em>The percent error</em>, % error, is <u>2.1%</u> (option f)
Explanation:
<u>1) Data:</u>
<u></u>
a) Experimental value, m₁ = 105.2 amu
b) Known value, m = 107.5 amu
b) % error = ?
<u>2) Formulae:</u>
a) absolute error = | experimental value - known value|
b) % error = [ absolute value / known value ] × 100
<u>3) Solution:</u>
a) absolute error = | m₁ - m | = | 105.2 amu - 107.5 amu | = 2.3 amu
b) % error = [ 2.3 amu / 107.5 amu ] × 100 = 2.1% ← answer
