A bunch of ballons contains many different colors. red 17 purple 11 orange 3 green 1 yellow 2 What is the probability that a randomly selected balloon will be red? Write your answer as a fraction or whole number.

1/2

Step-by-step explanation:

Number of red balloons = 17

Number of purple balloons = 11

Number of orange balloons = 3

Number of green balloons = 1

Number of yellow balloons = 2

Total number of balloons = 34

The probability that a randomly selected balloon will be red will be:

= Number of red balloons/Total number of balloons

= 17/34

= 1/2

CH 4 (g) + 20 2 (g)- CO 2 (g) + 2H 2 0 (g)

Explanation:

A balanced chemical reaction equation is one in which the number of atoms of each element on the reactants side is equal to the number of atoms of each element on the product side.

We can balance the equation by carrying out an atom count, that is, we count the atoms of each element on the reactant side and on the products side.

For instance;

Carbon has one atom on both sides of the reaction equation

Oxygen has four atoms on both sides of the reaction equation

Hydrogen has four atoms on both sides of the reaction equation.

Hence we can say that the reaction equation is balanced.
