Answer: A material that readily transmits energy is a conductor, while one that resists energy transfer is called an insulator .
i hope this will help u
pls add me as brainliest
Answer:
38.1 L
Explanation:
Data given:
initial volume V1 of a gas = 3 L
initial Temperature T1 of a gas = 21 °C
convert Temperature to Kelvin
T1 = °C +273
T1 = 21°C + 273 = 294 K
final Temperature T2 of a gas = 100°C
convert Temperature to Kelvin
T2 = °C +273
T2 = 100°C + 273 = 373 K
final Volume V2 of a gas = ?
Solution:
This problem will be solved by using Charles' law equation at constant pressure.
The formula used
V1 / T1 = V2 / T2
As we have to find out Volume, so rearrange the above equation
V2 = V1 x T2 / T1
Put value from the data given
V2 = 3 L x 373 K / 294 K
V2 = 38.1 L
So the final Volume of a gas = 38.1 L
Answer:
Add more substrate.
Explanation:
First let's explain why all the other options are wrong:
- The problem states that we <u>have optimum pH and optimum temperature</u>, this means that any change to those factors (increasing or decreasing) would slow down the reaction.
- <u>An inhibitor is called that way because its presence slows downs the reaction</u>, so more inhibitor would not speed up the reaction.
A <em>competitive inhibitor</em> is a substance that resembles the substrate that normally reacts with the enzime, so it binds to the enzime's active sites and prevents the substrate from doing so. Adding more substrate makes it more likely than a substrate molecule binds to an enzime's active site instead of the inhibitor ("it will outcompete the inhibitor and increase the reaction rate").
Answer:
11.7
Explanation:
The pH is the negative logarithm of the concentration of H+ ions. If the concentration is 2×10-¹² the the pH will be -log(2×10-¹²) which is 11.698 which can be round up to 11.7.
