Water is not found on the periodic table because it does not consist of a single element.
Answer :
The pressure of carbon dioxide in the atmosphere in mmHg is 0.239mmHg.
The pressure of carbon dioxide in the atmosphere in atm is
.
Explanation :
The conversion used for pressure from torr to mmHg is:
1 torr = 1 mmHg
The conversion used pressure from torr to atm is:
1 atm = 760 torr
or,

As we are given the pressure of carbon dioxide in the atmosphere 0.239 torr. Now we have to determine the pressure of carbon dioxide in the atmosphere in mmHg and atm.
<u>Pressure in mmHg :</u>
As, 
So, 
Thus, the pressure of carbon dioxide in the atmosphere in mmHg is 0.239mmHg.
<u>Pressure in atm:</u>
As, 
So, 
Thus, the pressure of carbon dioxide in the atmosphere in atm is
.
Answer:
Stronger!
Explanation:
The <u>stronger</u> the forces among the particles in a sample of matter, the more rigid the matter will be.
Answer:
![[A_0]=10\ mg](https://tex.z-dn.net/?f=%5BA_0%5D%3D10%5C%20mg)
Explanation:
Given that:
Half life = 10.4 hours
Where, k is rate constant
So,
The rate constant, k = 0.06664 hour⁻¹
Time = 24 hours
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t = 2 mg
is the initial concentration = ?
So,
![[A_0]=10\ mg](https://tex.z-dn.net/?f=%5BA_0%5D%3D10%5C%20mg)
Now, time = 3 days = 3*24 hours = 72 hours ( 1 day = 24 hours)
![[A_0]=10\ mg](https://tex.z-dn.net/?f=%5BA_0%5D%3D10%5C%20mg)
Thus,
During nuclear reactions some mass might be converted into energy and some energy might be converted into mass
