Answer:
Speed
Explanation:
Aliyah must have been trying to find her speed.
The speed is a measure of how fast an object or a body is and it is calculated by finding the ratio of distance with time. Mathematically,
speed = with a unit of m/s.
<em>Hence, with the distance measured on the ground and Aliyah trying to find the time it will take her to cover the distance while running, she must have been trying to find how fast she can run, that is, speed. </em>
The balloon will reach its maximum volume and it will burst.
Given:
To find:
Whether the weather balloon will reach its maximum volume or not.
Solution:
The pressure of the gas in the weather balloon at sea level =
The volume of the weather balloon at sea level =
The temperature of the gas in the weather balloon at sea level:
The balloon rises to an altitude.
The pressure of the gas in the weather balloon at the given altitude:
The volume of the weather balloon at the given altitude =
The temperature of the gas in the weather balloon at the given altitude:
Using the Combined gas law:
The maximum volume of the weather balloon= V = 835 L
The volume of the weather balloon at a given altitude is greater than its maximum volume which means the balloon will reach its maximum volume and it will burst.

Noble gases belong to group 18 of the periodic table. These elements are inert because they have their valence orbital shells as ‘full’ hence do not participate in reactions since they cannot share electrons. These elements have a pattern in their electron configuration. Their outer most orbital shells has 8 electrons (with the exception of 2 for helium).
Given question is incomplete. The complete question is as follows.
Gastric juice (pH 1.5) is produced by pumping HCl from blood plasma (pH 7.4) into the stomach. Calculate the amount of free energy required to concentrate the H in 1 liter of gastric juice at 37 degree of centigrade. Under cellular conditions, how many moles of ATP must be hydrolyzed to provide this amount of free energy? the free energy change for ATP hydrolysis under cellular conditions is about -58 kJ/mol. Ignore the effects of the transmembrane electrical potential.
Explanation:
The given data is as follows.
Gastric juice pH = 1.5, blood plasma pH = 7.4
Temperature = = (37 + 273) K
= 310 K
Now, relation between pH and concentration of hydrogen ions is as follows.
pH =
At pH = 1.5, we will calculate the as follows.
=
= M (
)
At pH = 7.4, we will calculate the as follows.
=
= M (
)
Also,
=
= 35 kJ/mol
So, the amount of ATP necessary to provide 35 kJ is as follows.
= 0.6 mol
Therefore, we can conclude that 0.6 moles of ATP must be hydrolyzed to provide this amount of free energy.
