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.
Barium has to give up 2 electrons to be like the nearest noble gas.
Answer:
d. carboxyl
Explanation:
The presence of carbonyl group (>C=O)) and a hydroxyl group ( (−OH) on the same carbon atom is called a "carboxyl" group. A carboxyl group is represented as COOH and acts as the functional group part of carboxylic acids.
For example:
- Formic acid or Methanoic acid (H-COOH)
- Butanoic acid (C3H7-COOH)
Hence, the correct option is "d. carboxyl ".
Answer:
1. 0.023 M H3O+.
2. pOH = 5.52.
3. pH=9.45
4. 0.0018 M OH-
Explanation:
Hello,
In this case, such order could be computed by means of the pH, the lower the pH the more acid the solution, thus:
1. 0.0018 M OH-:
2. 0.023 M H3O+
3. pH=9.45
4.
Therefore the order is
1. 0.023 M H3O+.
2. pOH = 5.52.
3. pH=9.45
4. 0.0018 M OH-
Best regards.
