The reaction that describe an acid an acid- base neutralization reaction is
Be(OH)2 + H2SO4 = BeSO4 +2 H2O
Neutralization reaction involve an acid and a base reaction whereby the acid neutralization the base. for the reaction above Be(OH)2 is the base while H2SO4 is the acid thus H2SO4 neutralizes Be(OH)2 to form BeSO4 and H2O
Answer:
B. The substance is in the liquid state.
Explanation:
The symbol (l) in a chemical equation represents that the substance is in liquid state which is one of the physical states of a chemical substance.
58kg
Explanation:
Given parameters:
Mass of bicycle = 8kg
Total force exerted = 191.4N
Acceleration = 2.9m/s²
Unknown:
Naomi's mass = ?
Solution:
Force is a product of mass and acceleration as sated in the second law of newton.
Force = mass x acceleration
Total force on the bicycle = total mass x acceleration
191.4 = (8 + k) 2.9
8 + k = 
= 66
K = 66 - 8 = 58kg
