Answer:

option 1

Explanation:

A chemical reaction occurs when two or more molecular structure rearrange causing a change in the chemical transformation of one of the substance. During a chemical reaction, old bonds break and new bonds are formed. The energy is conserved during a chemical reaction. The energy released during breaking of the old bonds are used to form new ones.

Thus. option 1 is correct.

<span>The statement that is true of the energies required to break bonds is this: 

the energy needed to break the required bonds is greater than the energy released when the new bonds form.

Bonds that have been formed during specific reactions require much energy to be broken down again because of the closed atomic bond that have formed during the process.</span>

Komok [63]

Answer:

g = 0.4 m/s²

Explanation:

Given the following data;

Height = 5 meters

Time = 5 seconds

To find the acceleration due to gravity (g) on the planet;

Mathematically, the maximum height of an object is given by the formula;

H = ½gt²

Where;

H is the height measured in meters.

g is the acceleration due to gravity.

t is time measured in seconds.

Substituting into the formula, we have;

5 = ½ * g * 5²

5 = 0.5 * g * 25

5 = 12.5 * g

g = 5/12.5

g = 0.4 m/s²

Kipish [7]

Answer:

shadow length 7.67 cm

Explanation:

given data:

refractive index of water is 1.33

by snell's law we have

n_{air} sin30 =n_{water} sin\theta

1*0.5 = 1.33*sin\theta

solving for\theta

sin\theta = \frac{3}{8}

\theta = sin^{-1}\frac{3}{8}

\theta =  22 degree

from shadow- stick traingle

tan(90-\theta) = cot\theta = \frac{h}{s}

s = \frac{h}{cot\theta} = h tan\theta

s = 19tan22 = 7.67 cm

s = shadow length
