The gas with a higher pressure is Helium
Calculating the pressure exerted by the gasesGiven that temperature and volume is held constant the pressure of a given gas can be calculated as : P = n because for a constant volume and temperature the pressure of a given gas is directly proportional to the number of moles of contained in the gas.
Pressure of Helium
P = n
where n ( number of moles ) = mass of helium / molar mass
= 52 / 4 = 13 moles
Pressure of Ammonia
P = n
where n ( number of moles ) = mass / molar mass of ammonia
= 73 / 17.03
= 4.29 moles
From the calculations above the gas with a higher pressure is Helium.

One gallon of paint will cover 400 square feet. How many gallons of paint are needed to cover a wall that is 8 feet high and 100 feet long?
2 gallons of paint are needed.
Granted there are no doors or windows, a 8ft by 100ft wall will have an area of 800 square feet (multiply length * height, so 8 * 100 = 800).
If each gallon of paint covers 400 square feet, we need to divide our area by 400. 800/400 = 2.
So, 2 gallons of paint are needed to cover the wall.

How is the temperature of a substance related to the kinetic energy of its molecules? select all that apply.
The kinetic energy is proportional to the temperature.
What is the relation between temperature and kinetic energy?
So first, we know that the kinetic energy of an object is given by:
K = (1/2)*m*v^2
Where v is the velocity and m is the mass.
We know that substances are made of molecules, and these molecules are tiny objects that move. As the temperature increases, you should see that the speed of motion of these particles increases (this is why dilation happens). So, if the velocity increases, then also increases the kinetic energy of the molecules in the substance.
The thermal velocity is approximated by:
[tex]v = \sqrt{(k/m)*T}[/tex]
Where (k/m) is a constant, now, if you replace that in the kinetic energy equation, you can see that the kinetic energy is proportional to the temperature.

The area of a circle is 153. 86 square meters. What is the diameter of the circle? use 3. 14 for π.
Answer:
14
Explanation:
A=pi × r²
153.86 = 3.14 × r²
Divide both sides of the equation by 3.14
it becomes:
r²=153.86÷3.14
r²=49
taking the square root for both sides of the equation
r = 7
and
diameter = 2 × radius
diameter = 2 × 7 = 14

The base of a parallelogram is half its height. The base measures 6 1/2 inches. Find the area of the parallelogram in square inches.
Answer: 84 1/2 or 84.5 same thing
Explanation:
It says the base is half the height and the height is 6 1/2. So you do 6 1/2 x 2 to get the height. And 6 1/2 x 2 = 13. The you do base x height so it would be 6 1/2 x 13. You have to make a mixed number so 6 1/2 as a mixed number is 13/2. When you have a whole number and your mutilpling with a fraction you put a one under it so 13 wwould turn into 13/1. Then you do 13/2 and 13/1 which equals 169/2. Next you divide 169 divided by 2 and that equals 84 remander 1. So the answer would be 84 1/2 or 84.5

The sum of two numbers is 640. The quotient of the same two numbers is 7 with a remainder of 64. What are the numbers?
Answer: 568 and 72
Explanation:
so you know answer is real
568
+ 72
------------------
640
The two numbers would be as follows:
568, 72
Find the numbersGiven that,
The sum of the two numbers = 640
The quotient of those numbers = 7
Remainder = 64
Now,
Let the two numbers be x and y.
From the given details, we can form two equations,
[tex]x + y = 640 ...(i)[/tex]
[tex]x - 7y = 64 ...(ii)[/tex]
By subtraction, we get
[tex]8y = 72[/tex]
∵ [tex]y = 9[/tex]
Now by putting the value of [tex]y[/tex] in (i), we get
[tex]x + 72 = 640[/tex]
⇒ [tex]x = 640 -72[/tex]
∵ [tex]x = 568[/tex]
Thus, the two numbers would be 568 and 72.

What is the ph of a 0. 65 m solution of the weak base pyridine?
Answer:
The pH of a weak base (in this case, pyridine is a weak base) is calculated by using the weak base equation, and then solving it.
C5H5N; Kb= 1.7 x 10⁻⁹
pH = -log [H⁺]
we can also say that pH = 14 + log [OH⁻]
Plugging into the weak base equation, we know that Kb = [OH⁻][BH⁺] / [B]
This can be solved using an ice chart, which will then simplify to :
Kb = [x][x] / [0.50-x]
We can assume that x is very small in comparison to the 0.5 , so we consider it zero.
Then plug in and solve for x. 1.79 *10-9 = x² / 0.5
x = 2.992 * 10⁻⁵
ince X is equal to the [OH⁻] concentration, we can plug it into the second pH equation, and get the pH!
pH = 14+ log 2.99 * 10⁻⁵
pH = 9.48
