Answer:
The sources of solid waste include residential, commercial, and industrial activities.
Residences and homes where people live are some of the major sources of solid waste. Garbage from these places include food wastes, plastics, paper, glass, leather, cardboard, metals, yard wastes, ashes and special wastes like bulky household items like electronics, tires, batteries, old mattresses and used oil.
Answer:
Nitrogen A would be more nucleophilicity (figure 1.)
Explanation:
In the <u>DMAP </u>molecule we will have 2 nitrogens label as "nitrogen A" and "nitrogen B". For nitrogen B we will have more<u> steric hindrance</u> due to the 2 methyls groups and the benzene ring. What will hinder the attack from this nitrogen (nitrogen B) to an <u>electrophile</u>. On the contrary, the attack of nitrogen A could easily occur.
Answer : The correct expression for equilibrium constant will be,
Explanation :
Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.
The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.
As we know that the concentrations of pure solids and liquids are constant that is they do not change. Thus, they are not included in the equilibrium expression.
The given equilibrium reaction is,
The expression of will be,
Therefore, the correct expression for equilibrium constant will be,
Answer:
A
Explanation:
Ball bounces because of the difference in the air pressure on the outside of the ball, and opposite the point of impact, and the pressure inside of the ball. This means that the inside of the ball now has less space to contain the air molecules contained inside the ball, increasing the pressure inside the ball.
<span>The best answer among
the choices is the first option. The chemical property of soda is that it is a
highly basic substance. It's chemical name is sodium carbonate. It is more
basic than sodium bicarbonate. Adding soda ash in a solution would increase the
pH of the solution.</span>
