Answer:
d
Explanation:
they either gain valence electrons or share them depending on what elements or compound they are reacting with
Answer : The rate order of reaction is, second order reaction.
Explanation :
Rate of reaction : It is defined as the rate of change in concentration of reactant or product with respect to time.
Order of reaction : It is defined as the sum of the exponents or powers to which the molar concentration in the rate law equation are raised to express the observed rate of reaction.
As per question the reaction will be :
The given rate expression is,
From this expression we conclude that the power of concentration of reactant A and B are 1, 1.
The sum of power of concentration of reactant A and B = 1 + 1 = 2
That means it is a second order reaction.
Hence, the rate order of reaction is, second order reaction.
Answer:
a. endothermic
Explanation:
- Endothermic reaction: is a chemical reaction that absorbs heat or energy through the reaction.
- While, exothermic reaction: is a chemical reaction that releases energy through light or heat. It is the opposite of an endothermic reaction.
<em>So, Any reaction that absorbs 150 kcal of energy can be classified as </em><em>a. endothermic.</em>
Answer: Acidic liquids have low pH levels. Many fruit juices qualify as acidic liquids. Some of the more acidic fruit juices are orange juice, lemon juice, grapefruit juice, tomato juice and red currant juice.
