Chemical equation
Explanation:
A chemical equation is an expression that represents a chemical reaction. The formula of the reactants are connected by an arrow with the formula for the products.
Chemical reactions are made up of reactants and products which all together forms a chemical equation.
- The reactants are positioned on the left hand side of a chemical equation. It is the specie that forms the product.
- The products are on the right hand side and they are the result of a chemical change.

The answer is Computer game.
Scientific modelling is an experimental enterprise, the purpose of that is to make a distinct section or piece of the universe accessible to recognize, describe, quantify, imagine, or invent by connecting it to existing and customarily ordinarily allowed information.
Answer:
513 m
Explanation:
We have;
final speed of the airplane = 193.0 km/h * 1000/3600 = 53.6 m/s
acceleration of the air plane = 2.80 m/s2
initial velocity of the airplane = 0 m/s
length of the runway = distance covered
v^2 = u^2 + 2as
v^2 - u^2 = 2as
s = v^2 - u^2/2a
s = (53.6)^2 - 0^2/ 2 * 2.80
s = 2872.96/ 5.6
s = 513 m
It be desirable to use an energy resource that does not produce greenhouse gases because it contribute to climate change
.
Option C
<u>Explanation:</u>
Greenhouse gases are the toxic gases that contribute to the "greenhouse effect". Greenhouse gases have the ability to absorb and emit some of the outgoing energy that is radiated by the Earth's surface, eventually causing the heat to get accumulated in the "lower atmosphere". It is always beneficial to use Renewable Energy sources such as Wind, solar and water which gives no harm to the environment and climate with no greenhouse gas emissions.
<u>For example:</u> If we have to generate electricity, there will be no greenhouse gas production at the beginning and a very less amount of production at the entire life cycle.
