<h3><u>Answer;</u></h3>
increase the temperature from 27 degrees celsius to 37 degrees celsius
<h3><u>Explanation;</u></h3>
- The rate of an enzyme-catalyzed reaction increases as the temperature is raised.
- <em><u>The human body is maintained at 37°C as this is the temperature at which the enzymes in our body work best. Therefore increasing the temperature from 27 degrees Celsius to 37 degrees Celsius increases enzyme activity and in turn increases the production of amino acid in the flask.</u></em>
- Higher temperatures than 37° C which is the optimum temperature, disrupt the shape of the active site, which will reduce enyzme activity, or prevent it from working, in other words the enzyme will have been denatured.
Answer:
Excited state of an electron is the state attained by an electron after it has absorbed energy and it moves further from the nucleus.
an electron is at higher energy when excited and at lower energy when at ground state.
an excited electron is less stable due to the decrease in the nuclear force of attraction and the grounded electron is more stable due to it's close distance to the nucleus.
Answer:
Explanation:
We are asked to find the pressure of a gas given a change in volume. Since the temperature remains constant, we are only concerned with volume and pressure. We will use Boyle's Law, which states the volume is inversely proportional to the pressure. The formula for this law is:
Initially, the oxygen gas occupies a volume of 18.7 liters at a pressure of 1.19 atmospheres.
The gas expands to a volume of 29.4 liters, but the pressure is unknown.
We are solving for the new pressure, so we must isolate the variable 
. It is being multiplied by 29.4 liters. The inverse operation of multiplication is division. Divide both sides of the equation by 29.4 L.
The units of liters cancel.
The original measurements all have 3 significant figures, so our answer must have the same. For the number we calculated, that is the thousandth place. The 9 in the ten-thousandth place to the right of this place tells us to round the 6 up to a 7.
The pressure of the gas sample is approximately <u>0.757 atmospheres.</u>
The more work someone does, the more energy they need. For example, if someone is moving a large couch they are going to use a lot of energy because it is heavy. However, if the couch was smaller, they would be using less energy because it does not weigh as much as they will not become as tired!
