Answer:

D. 2NH₃(g) ⟶ N₂(g) + 3H₂(g)

Explanation:

A chemical equation must show the correct formulas for reactants and products.

A and B are wrong, because they have NH₃ as a product.

C is wrong. H₃ does not exist.

A is correct. The equation for the decomposition of ammonia is

2NH₃(g) ⟶ N₂(g) + 3H₂(g)

Find the equation of the line passing through the points (2, 1) and (5, 10).​
Vedmedyk [2.9K]

The equation : y=3x-5

<h3>Further explanation </h3>

Straight-line equations are mathematical equations that are described in the plane of cartesian coordinates

General formula

y-y1 = m(x-x1)

or

y = mx + c

Where

m = straight-line gradient which is the slope of the line

x1, y1 = the Cartesian coordinate that is crossed by the line

c = constant

The formula for a gradient (m) between 2 points in a line

m = Δy / Δx

  • Gradient

\tt \dfrac{10-1}{5-2}=3

  • Equation

\tt y-1=3(x-2)\\\\y-1=3x-6\\\\y=3x-5
