Answer:
A. Chlorine
Explanation:
Chlorine has 17, Hydrogen has 1, Oxygen has 8, Sulfur has 16.
Soil can get swept away into the water (by wind, gravity, rain, etc) and can increase the water level of the body of water.
Another thing is that if the soil was infected with pesticides from farmer's crops then the toxins that were in the soil can pollute the body of water. hope this helps!!
Answer:
1. 505g is the mass of the aluminium.
2. The answer is in the explanation
Explanation:
1. To solve this question we need to find the volume of the rectangle. With the volume and density we can find the mass of the solid:
Volume = 7.45cm*4.78cm*5.25cm
Volume = 187cm³
Mass:
187cm³ * (2.702g/cm³) = 505g is the mass of the aluminium
2. When the temperature of a liquid increases, the volume increases doing the density decreases because density is inversely proportional to volume. And works in the same way for gases because the temperature produce more collisions and the increasing in volume.
Each unit of pH represents a change by a factor of 10. Thus in a pH of 5, there would be 100x the concentration of Hydrogen ions in solution.
The correct option would be 2.
