A sample of carbon dioxide gas at 125°c and 248 torr occupies a volume of 275 l. What will the gas pressure be if the volume is increased to 321 l at 125°c?.
The new pressure of gas when the volume of the gas is increase to 321 L at 125 °C is 212.46 torr
Data obtained from the question Initial pressure (P₁) = 248 torrInitial volume (V₁) = 275 LTemperature = 125 °C = constant New Volume (V₂) = 321 LNew pressure (P₂) =?How to determine the new pressure
The new pressure of the gas can be obtained by using the Boyle's law equation since the temperature is constant. This is illustrated below:
P₁V₁ = P₂V₂
248 × 275 = P₂ × 321
68200 = P₂ × 321
Divide both side by 321
P₂ = 68200 / 321

A gas has a pressure P at 27 °C. To calculate its pressure at 57°C we use an expression derived from Gay-Lussac's law:
C) P2 = (300/330) P
What does Gay-Lussac's law state?Gay-Lussac's law states that the pressure of a given mass of gas varies directly with the absolute temperature of the gas when the volume is kept constant.
Mathematically, it can be written as:
P/T = k
A gas has a pressure P at 27 °C and we want to find the expression to calculate its pressure at 57°C.
Step 1: Convert the temperatures to the Kelvin scale.We do so by summing 273.15.
K = 27 + 273.15 = 300 K
K = 57 + 273.15 = 330 K
Step 2: Apply Gay-Lussac's law.P2/330 = P/300
P2 = (300/330) P

Zinc reacts with iron (iii) chloride yielding zinc chloride plus iron
Answer:
I don't see a specific question, so I'll make a few comments and hope that answers the reason for the post.
Explanation:
Zinc(Zn) does react with iron chloride, since zinc is a more reactive metal than the iron.
When Zn is introduced to an iron (III) chloride solution, the Zn disoplaces the Fe atom in a displacement reaction.
The chemical equation of the reaction:
Zn + Fe(III)Cl3 → ZnCl3 + Fe
Energy is often realeased in this type of reaction, since the resulting chemical products have a lower energy that the reactants.
There are several metals more reactive than iron. One of the more interesting examples of a highly exothermic reaction with iron chloride (rust) is the reaction of aluminum with iron chloride. `This is highly exothermic and is labelled a thermite reaction. It provides a spectacular flame that is not enough to weld railroad tracks together.

What is exothermic reaction?In this type of reaction, the energy of the products is lower than the energy of the reactants. As a result, the difference in energy is released as heat or light, which can be detected by measuring the temperature or observing the light emitted during the reaction.
Exothermic reactions occur spontaneously, meaning they do not require an external energy source to start the reaction. Common examples of exothermic reactions include combustion, oxidation, and neutralization. These reactions often involve the formation of stronger bonds between atoms or molecules, which releases energy in the form of heat or light.

What causes “gaps in the rock record” and how is that described?
Answer:
An unconformity is a widespread surface separating rocks above and below, which represents a gap in the rock record. Unconformities occur when either erosion wears away rocks, or rock deposits never form. Therefore, a time gap exists between when the rocks below the unconformity formed and when those above it formed.
