Answer:
The solution is neither acidic or basic. An acid is a substance that donates hydrogen ions. ... Because the base "soaks up" hydrogen ions, the result is a solution with more hydroxide ions than hydrogen ions. This kind of solution is alkaline. Acidity and alkalinity are measured with a logarithmic scale called pH.

Answer:
0.5 mole
Explanation:
C=12u
O=16u
1 mole carbon dioxide=44 grams
so 22grams = 0.5 mole
When reactants are mixed and heated and liquid collects in the sidearm of the apparatus, a chemical reaction is occurring.
<h3>What is a chemical reaction?</h3>
A chemical reaction is said to occur when reactants are combined to form products. We must note that the formation of products is evidenced by;
- Appearance of a liquid
- Appearance of a gas
- Appearance of a solid
Hence, when reactants are mixed and heated and liquid collects in the sidearm of the apparatus, a chemical reaction is occurring.

Answer:
22s
Explanation:
Given parameters:
Acceleration = 25m/s²
Final velocity = 550m/s
Initial velocity = 0m/s
Unknown:
Time taken = ?
Solution:
To solve this problem, we are going to use one of the motion equations:
v = u + at
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time taken
550 = 0 + 25 x t
550 = 25t
t = 22s
