True. When pesticides make it to a water source, this water source becomes polluted, and unsafe for humans, animals, plants, etc.
Answer:
2.21% wt/v
Explanation:
The mass/volume percentage, %wt/v, is an unit of concentration used in chemistry defined as 100 times the ratio of the mass of solute in g (In this case, CaCl2 = 1.77g) and the volume of solution in mL = 80mL
The %wt/v of this solution is:
%wt /v = 1.77g / 80mL * 100
%wt/v = 2.21% wt/v
A. Oxyacids is the name of acids that contain a polyatomic ion and have oxygen
In a fully inflated basketball, there are more particles of gas.
Answer: Option D.
<u>Explanation:</u>
When a ball is fully inflated, it means it has a lot of air in it. With a lot of air in it, it means that there a lot of gas particles in that ball. With the large amount of gas particles in it, there is a lot of collision among these particles inside the ball.
This collision leads to the pressure on the greater side compared to the ball which has less air in it and is deflated because it has less particles of gas inside.
N. <span>Therefore, the 1p </span>orbital<span> doesn't exist. In the second shell, both 2s and 2p </span>orbitals<span>exist, as it can have a maximum of 8 electrons. In the third shell, only the 3s, 3p and 3d </span>orbitals<span> exist, as it can hold a maximum of 18 electrons. Therefore, the </span>3f orbitals<span> do not exist.</span>
