Answer:
To determine the relationship between pressure and temperature in this scenario, we can use the ideal gas law.
The ideal gas law states that PV = nRT, where P represents pressure, V represents volume, n represents the number of moles of gas, R is the ideal gas constant, and T represents temperature in Kelvin.
Since we only have the initial and final pressures and temperatures, we can compare them using the ideal gas law equation by setting up the following ratio:
(P₁T₁) / (P₂T₂) = (V₁n₁R) / (V₂n₂R)
Since the volume, number of moles, and gas constant remain constant, we can simplify the equation:
(P₁T₁) / (P₂T₂) = 1
Now, we can substitute the given values into the equation:
(53.0 atm * T₁) / (35.2 atm * 12.0°C) = 1
To solve for T₁, we need to convert 12.0°C to Kelvin by adding 273.15:
(53.0 atm * T₁) / (35.2 atm * (12.0 + 273.15) K) = 1
Simplifying the equation further:
(53.0 atm * T₁) / (35.2 atm * 285.15 K) = 1
Now, we can solve for T₁:
(53.0 atm * T₁) = (35.2 atm) * (285.15 K)
Dividing both sides of the equation by 53.0 atm:
T₁ = (35.2 atm * 285.15 K) / 53.0 atm
Calculating the numerical value:
T₁ ≈ 189.5 K
Therefore, when the pressure changes from 53.0 atm to 35.2 atm, the temperature changes from approximately 12.0°C to 189.5 K.
Answer:
The answer to your question is 68 g
Explanation:
Data
mass of H₂ = 12 g
mass of NH₃ = ?
Balanced chemical reaction
3H₂ + N₂ ⇒ 2NH₃
Process
1.- Calculate the molar mass of H₂
H₂ = 1 x 6 = 6
NH₃ = 2[(14 x 1) + (3 x 1)]
= 2[14 + 3]
= 2[17]
= 34 g
2.- Use proportions to find the mass of NH₃
6 g of H₂ --------------- 34 g of NH₃
12g of H₂ ---------------- x
x = (12 x 34) / 6
x = 408/6
x = 68 g of NH₃

A)The temperature of the balloon
B)The diameter of the balloon
C)The amount of air
D)The three balloons
To solve this we must be knowing each and every concept related to experiment. Therefore, the correct option is option B among all the given options.
An experiment is a qualitative approach used in the scientific process to settle disputes between competing products or hypotheses. Additionally, experiments are used by researchers to confirm or refute new or existing theories.
A student designs an experiment where she will put the same amount of air into three different balloons. One balloon will be submerged in ice water, one balloon will be carefully heated with a hair dryer, and the last balloon will be left alone. After making the changes, the student then will then measure the diameter of each balloon. The dependent variable is the diameter of the balloon.
Therefore, the correct option is option B.

Filtering helps produceclean water by...
Explanation/summary/reasons:
Filtering dirty water can take away the tap water odor, heavy metals, bacteria and dirt that can cause a person to get infected or sick. Filtering can even remove the chloride inside the dirty water and reduces limescale and acid reflux and can make clean water have anti-oxidant properties in it. Filtered and clean water is better for the environment and healthier by improving skin health and healthier for making tea,coffee and healthier smoothies. Water can also enhance hydration, energy, helps get rid of headaches, reduces cardio stress and improves digestion. It even saves more money from your wallet as well!
