Answer:
The answers to the question are as follows
a. True
b. True
c. True
d. false
Explanation:
The requiredrelation is
Where R = The gas constant
T = the temperature in kelvin
m = molecular mass
= root mean square speed
From the above relation on the kinetic energy of a gas we have the following true statements
a. When the temperature of either of the sample of gas increases, the root-mean-square speed increases.
This statement is true as the root means square velocity is directly proportional to the square root of the temperature a. is true
b. If both gases are at the same temperature, they have the same average kinetic energy.
From the equation for the average kinetic energy 
we see that the kinetic energy is directly proportional to its Kelvin temperature and hence b. is true
c. When the temperature of either sample of gas increases, the number of particles with average kinetic energy increases.
This statement is true as shown in the kinetic energy equation
d. If both of the containers are at the same temperature, they will have the same root-mean-square speed.
This statement is false as xenon and helium have different, molecular masses
1.512 x 10^5
You simply move the decimal point to the left until you get a number greater than or equal to one, and less than 10, then take that number, and the number of decimal places you moved is the exponent.
Answer:
<u>The answer is 6.55 * 10⁻⁷</u>
Explanation:
Let's write 0.000000655 mL in scientific notation:
The first step is you have to move the decimal place until you have a number between 1 and 10. If you keep moving the decimal point to the right in 0.000000655 you will get 6.55.
Now, the second step is you count how many places you moved the decimal point. You moved it 7 places to the right to change 0.000000655 to 6.55.
Finally, You need to show that you moved the decimal point 7 places to the right by noting that the number should be multiplied by 10⁻⁷ because a power of ten with a negative exponent, such as 10⁻⁷, means the decimal was moved to the right.
<u>The answer is 6.55 * 10⁻⁷</u>
Answer:
A and B as well C are the compounds.
Explanation:
- A seems to be a compound, very least, it appears to contain carbon and oxygen.
- C seems to be a compound, containing respectively oxygen as well as carbon.
- B isn't always described by that of the information provided, it is therefore presumably a compound because there are few components as white solid particles.
So that the above is the correct answer.
The pH of water is 7
5.3 to 4.3 is more acidic. 1 pH is more acidic than 2 pH The base starts at 8.
