<span>Scientists ignore the forces of attraction between particles in a gas under ordinary conditions</span><span> because the particles in a gas are apart and moving fast, rather than clustered and moving slow, therefore the forces of attraction are too weak to have a visible effect.</span>
The answer to the question is Eight
Answer:
1. C. take in carbon from the air. The carbon is used to make energy storage
molecules.
2. b Carbon is moving into the air and out of the air at the same time
Explanation:
Question 1:
Trees are plants, which are autotrophic organisms i.e. set of organisms that are capable of producing their own food via a process called PHOTOSYNTHESIS. This photosynthetic process produces sugars (glucose) in the presence of SUNLIGHT. According to this question, the sun has been up for several hours, and has been shining on these trees. This means that the trees can take in carbo dioxide (CO2) in order to perform the process of photosynthesis. Also, the number of energy storage molecules in the trees (ATP) will INCREASE.
What can the trees do because they are in sunlight? What does this mean for the ?
Answer : The value of rate constant is, 
Explanation :
First we have to calculate the rate constant, we use the formula :
Expression for rate law for first order kinetics is given by:
where,
k = rate constant = ?
t = time passed by the sample = 20 min
a = let initial amount of the reactant = 100 g
a - x = amount left after decay process = 100 - 85 = 15 g
Now put all the given values in above equation, we get
Therefore, the value of rate constant is,
