Which gas will have the least collisions between its particles?

A. Helium at 20 C
B. Oxygen at -45 C
C. Carbon dioxide at 80 C
D. Argon at 265 K

Answers

AWNSER: A.


WHY: oxygen we breathe so there’s nothing too bad about oxygen carbon dioxide yes it’s kind of thick air though it won’t work so helium is the only good answer here

The gas that has the least collisions between its particle is helium at 20° C. The correct option is A.

What is collision?

Collision is a term used when two particles or object collides or clash and there is an exchange or transformation of energy between them. When a collision happens, the force is exerted on each other.

Helium is the second most abundant element present in the atmosphere. It is the lightest gas and its particle collides when there is an increase in the temperature.

Thus, the correct option is A. Helium at 20° C., regarding the collision of particles between its particles.

The item that is significantly made up of one or more molecules is hydrogen. Thus, the correct option for this question is B.

What is a Molecule?

A molecule may be defined as a group of one or more atoms that are held together by numerous chemical bonds. It is the smallest particle of a substance that has all sorts of physical and chemical properties of that substance.

Among the given options, gold and neon are the elements, while salt is a compound. Hydrogen is a gas of diatomic molecules bearing the formula H2. It is colorless, tasteless, odorless, non-toxic, and highly combustible. Hydrogen in its molecular form is more common.

A hydrogen molecule is one of the simplest possible molecules which significantly consists of two protons and two electrons. These protons and electrons are remarkably held together by electrostatic forces.

Therefore, the item that is significantly made up of one or more molecules is hydrogen. Thus, the correct option for this question is B.

0.254g lead(ii)ethanoate, on adding excess K2CrO4 solution, gave 0.130g of lead(ii)chromate precipitate. what is the percentage composition of Pb in the organic salt? (O = 16, Cr = 52, Pb = 207).​

Answers

Answer:

32.8%

Explanation:

All of the Pb⁺² species precipitated as lead(II) cromate, PbCrO₄ (we know this as excess K₂CrO₄ was used).

First we convert 0.130 g of PbCrO₄ into moles, using its molar mass:

0.130 g ÷ 323 g/mol = 4.02x10⁻⁴ mol PbCrO₄

There's 1 Pb⁺² mol per PbCrO₄ mol, so in total 4.02x10⁻⁴ moles of Pb⁺² were in the ethanoate sample.

We convert those 4.02x10⁻⁴ moles of Pb into grams:

4.02x10⁻⁴ mol * 207 g/mol = 0.083 g Pb

Finally we calculate the percentage composition of Pb:

0.083 g Pb / 0.254 g salt * 100% = 32.8%

A hot piece of copper was dropped into 155 g of water at 23.6 °C and 2,100 J of energy was transferred to the water. What is the final temperature of the water?​

Answers

Answer:

26.8 °C

Explanation:

Step 1: Given and required data

Mass of water (m): 155 gEnergy transferred to the water (Q): 2100 JInitial temperature of the water (T₂): 23.6 °CFinal temperature of the water (T₁): ? Specific heat of water (c): 4.184 J/g.°C

Step 2: Calculate the final temperature of the water

We will use the following expression.

Q = c × m × (T₂ - T₁)

T₂ = 2100 J/(4.184 J/g.°C) × 155 g + 23.6 °C = 26.8 °C

The answer is When The final temperature we (reached by both copper and also water) is 38.7 °C.  This method can also be used to determine other quantities, also it helps a lot such as the specific heat of an unknown metal. Step 1: when Given and required data is:When The Mass of water (m): 155 gWhen the Energy transferred to the water is (Q): 2100 JAfter that initial temperature of the water is (T₂): 23.6 °CNow when the Final temperature of the water is (T₁):?when The Specific heat of water (c): 4.184 J/g. °CStep 2: Now Calculate the final temperature of the water is:Now We will use the following expression is:Then follow this formula Q = c × m × (T₂ - T₁)

What are two things that interact that determine if there is a phase change or not HELP

Answers

Answer:

phase change always has two phases in contact during the change. melting => solid & liquid; evaporation (boiling) => liquid & vapor. If only one phase is present, then phase change is not occurring. Also, when two phases are in contact, no temperature changes occur. Only the pure phase demonstrates temperature change when measured. Example, when ice is added to water, at thermal equilibrium (temp = 0°C) the water temp will not continue to change. Only when all the ice has melted will the water temperature demonstrate a measured temperature change.
