Answer:
The catalyzed reaction will take time of 
.
Explanation:
According to the Arrhenius equation,
The expression used with catalyst and without catalyst is,
where,
= rate of reaction with catalyst
= rate of reaction without catalyst
= activation energy with catalyst = 59.0 kJ/mol = 59000 J/mol
= activation energy without catalyst = 184 kJ/mol = 184000 J/mol
R = gas constant
T = temperature = 
Now put all the given values in this formula, we get:
The reaction enhances by 
when catalyst is present.
Time taken by reaction without catalyzed = 3900 years
Time taken by reaction with catalyzed = x
The catalyzed reaction will take time of .
Their is 2 valence electrons
Newton's first law of motion states that an object at rest will remain at rest unless an unbalanced force acts on it. If you apply balanced forces on the object there would be no net force. The body does not accelerate but instead stays at rest.
Another way to look at this problem is to use Newton's second law of motion. The first law states that 
, where 
is the acceleration
is the net force and 
is the mass of the object.
When F is zero, the acceleration of the object is zero. This means that if the object had a velocity of zero before the balanced forces started acting, the velocity will stay at zero after the balanced forces begin to act. If the object was moving at a constant velocity before the balanced forces started acting on it, it would continue at that constant velocity after the balanced forces begin to act.
An average quality lawn captures 4 times the carbon output of a typical gasoline-powered mower.
Answer:
It is important to collect all data first, or else your guesses could purely be the opposite of the right answer. If you make inferences of what might happen, your guesses may be purely fictional, and totally off-topic. During experiments, this step is important.
