Lithium metal reacts with nitrogen gas to form lithium nitride. identify the balanced reaction that describes this process
Arlecino [84]

Lithium metal reacts with nitrogen gas to form lithium nitride the balanced chemical equation will be 6Li + N₂ → 2Li₃N.

<h3>What is a balanced chemical reaction?</h3>

In a balanced chemical reaction, the number of moles that are present at the side of the reactant must be always equal to the side of product formation this is known as a balanced chemical equation.

The balanced chemical reaction will be 6Li + N₂ → 2Li₃N.

Here 6 moles of lithium is reacting with one nitrogen but as it is in gaseous state it is N₂ after reacting with lithium it will give two moles

Therefore, balanced equation will be 6Li + N₂ → 2Li₃N

An object that has a height of 0.4 meter is placed at a distance of 0.7 meter from a concave spherical mirror. An image is forme
julia-pushkina [17]

Answer: B. 0.6125 m

For spherical concave mirror:

Height of the object, h_o=0.4\hspace{1mm}m

Height of the image, h_i=0.35\hspace{1mm}m

Object distance, u=-0.7 m

we need to find the distance of the image, v.

These are related by the following formula:

\frac{h_i}{h_o}=-\frac{v}{u}\\ \Rightarrow v=u\times\frac{h_i}{h_o}

Insert the values:

v=-(-0.7\times\frac{0.35}{0.4})=0.6125\hspace{1mm}m

Hence, option B is the correct.
