What are the missing coefficents for the following equation? __N2+__H2->__NH3
vivado [14]

Answer:

1, 3, 2

Explanation:

N2 + H2 → NH3

I usually find that the best way to systematically balance an equation by inspection is to start with the most complicated-looking formula and then balance atoms in the order:

  1. All atoms other than O and H
  2. O
  3. H

(a) The most complicated formula is NH3.

(b) Balance N.

We have 1 H in NH3, but 2 N on the left. We need 2 N on the right. Put a 1 in front of N2 and a 2 in front of NH3.

1N2 + H2 → 2NH3

(c) Balance H.

We have fixed 6 H on the right, so we need 6 H on the left. Put a 3 in front of H2.

1N2 + 3H2 → 2NH3

The equation is now balanced, and the coefficients are 1, 3, 2.

How are the formulas and names of ionic compounds written
MA_775_DIABLO [31]
Put the cation (a positive ion, the metal in this case,) without changing anything, then the nonmetal, or anion. For the nonmetal, change the ending to -ide. For example, if you have potassium and chlorine, you would have potassium chloride. Hope this helps!

What may cause some short term environmental changes how would organisms respond to these changes
jolli1 [7]

Answer:

Refer to explanation

Explanation:

Weather is the main cause behind most short term environmental changes

For example, a period of heavy rain may lead to a pond overflowing, and flooding the nearby shrubbery

Animals in the area would adapt to this by trying to keep away from the flooded area until it dries out, once the rain ends
