The interaction between the substances and stomata is a chemical reaction, light energy strikes at the chlorophyll molecules, whose electrons gets excited to a state of higher energy, and they come back to their state of lower energy by emission of energy, which is accepted by a chain of acceptors, and energy is generated.
The ball's potential energy will decrease, and its kinetic energy will increase.
Explanation:
The ball's potential energy will decrease down the slope and its kinetic energy will increase.
Kinetic energy is the energy due to the motion of a body.
K. E = 
m v²
m is the mass of the ball
v is the velocity of the ball.
Potential energy is the energy due to the motion of a body down slope.
It is expressed as:
P.E = mgh
m is the mass of ball
g is the acceleration due to gravity of the body
h is the height.
We can see as the body drops down the slope, the height diminishes and the velocity increases.

Answer:
See explanation
Explanation:
We know that the process of the oxidation of SO2 to SO3 is catalysed by NO2 gas. It occurs in two stages and i will show the balanced reaction equation of the both stages below;
Step 1
2NO2(g) + 2SO2(g) ------> 2NO(g) + 2SO3(g)
Step 2
2NO(g) + O2(g) -------> 2NO2(g)
So, the overall reaction equation is;
2SO2(g) + O2(g) ------> 2SO3(g)
Answer:
This reactivity order reflects both the strength of the C–X bond, and the stability of X(–) as a leaving group, and leads to the general conclusion that alkyl iodides are the most reactive members of this functional class.
Answer:
45.95 Jkg^-1°C^-1
Explanation:
as specific heat capacity = heat energy / mass × delta
temperature
=52500/10.2×112
=45.95 Jkg^-1°C^-1
