Answer:

A. 14/15

B. 17/14

C. 5/12

Explanation:

Convert all so that the denominators are the same.

A. 3/5 + 1/3 = 9/15 + 5/15 = 14/15

B. 5/7 + 1/2 = 10/14 + 7/14 = 17/14

C. 1/6 + 2/8 = 4/24 + 6/24 = 10/24 = 5/12

The continued use of fertilizer can cause a change in the pH of the growing medium. Which of the following materials will make t

salantis [7]

Answer:

B. Calcium nitrate

Explanation:

A soil will have an increase in pH if calcium nitrate is added to it. Calcium nitrate typically increases the alkalinity of soils when added to it.

Alkalinity is the degree of hydroxide ions concentration in the soil. This leads to increasing pH which tends towards the region of more bascity.

When calcium nitrate is added to the soil, the plants uses an hydrogen ion to take up nitrate.
Then an hydroxyl ion is excreted or released into the soil into the process.
Nitrate based fertilizers do not acidify soils.
