I suppose that you want to produce a 0.25 M solution of KCl

You do not want tp produce 0.25 mol of KCl.

Molar mass KCl = 39.1 + 35.45 = 74.55 g/mol

Mass of 0.25 mol KCl = 0.25 mol * 74.55 g/mol =18.64 g

To produce a 0.25 M solution of KCl = 18.64 g would require a solution volume of 1.0 L or 1000 mL

You have only 5.00 g ( NOT 5.00 gm) of KCl

Volume of solution required = 5 g / 18.64 g * 1000 mL = 268 mL solution

You dissolve the 5 g KCl in some water and then make up the final solution volume to 268 mL

This does NOT mean that you dissolve the 5 g KCl in 268 mL water .

Both trials of 1.2 g and 1.6 g will have the same mass percent of water because the ratio of the salt to the water of hydration is always constant for any hydrated salt.

For every hydrated salt, the ratio of the salt to the water of hydration remains constant irrespective of the amount of salt taken for experimental analysis.

For example, assuming the mass percent of water in 10g of a hydrated salt is 40%, if 100g of the same salt is taken, the mass percent will remain 40%.

It is not possible for the structure to be an isomer of butanoic acid because it consists of 5 carbon atoms.

An isomer of butanoic acid is a chemical compound with the same molecular formula but a different structural arrangement of its atoms.

Butanoic acid, also known as butyric acid, has the molecular formula C₄H₈O₂. It is a carboxylic acid with a straight-chain arrangement of four carbon atoms.

One isomer of butanoic acid is called isobutyric acid (2-methylpropanoic acid). Isobutyric acid has the same molecular formula C₄H₈O₂, but its carbon atoms are arranged in a branched structure.

So from the given structural formula, it is not possible for the structure to be an isomer of butanoic acid because it consists of 5 carbon atoms.

Answer:

100.09 amu is the answer.

Answer:

45g

Explanation:

first we will find out which is the limiting reactant (hope you know how to find it)

Cao is the limiting reactant

so

we will find the number of moles of cao which is 0.45 mol

as according to the equation cao and caco3 have ratios 1:1 so both will have the same no. of moles

then by multiplying 0.45mol by 100 (mr of caco3) we will get the mass of caco3 which is 45g

Explanation:

The shortest bond distance is at N2 due to its high bond order of 3. From N2 to F2 the bond distance increases despite the fact that atomic radius decreases.

H₂ is the diatomic molecule or ion that has the shortest bond length.

Diatomic atoms are those atoms which are composed of two atoms that are joined by a chemical bond.

H₂ is the simplest diatomic molecule is this.

It is diamagnetic and has only two molecular orbitals (g and u), two electrons, and a bond order of one.

It has a 74 pm bond length.

Thus, H₂ is the diatomic molecule or ion that has the shortest bond length.

Answer: The liquid oxygen machine is producing less liquid oxygen than normal because there's a low attraction between the molecules.

It should be noted that oxygen in its liquid state will take up less space. It can also be stored at a lower pressure than when it's in its gaseous state.

Explanation:

From the complete question, the liquid oxygen evaporates at a slightly higher The reason for this is due to the fact that they have similarly low attraction between molecules.

The amount of heat energy lost by the 100 mL of water when it all freezes is 33400 J

Mass = Density ×Volume

Mass of water = 1 × 100

Mass of water = 100 g

Q = m × ΔHf

Q = 100 × 334

C. Burning oil

Explanation:

Water cannot be used as a fire extinguisher to extinguish the flames of burning oils such as gasoline, petrol, or diesel. Because oil is lighter than water, it floats on top of it and cremates. Furthermore, as the water spreads and carries the oil with it, the fire spreads over a larger area.

The resulting volume of the tire would be 1.1 L

According to this law, the volume of a given gas is directly proportional to its temperature, provided that the pressure remains constant.

The law can be presented mathematically as;  

[tex]\dfrac{V_1}{T_1} =\dfrac{V_2}{T_2}[/tex]

In this case, V1 = 1.0 L, T1 = 22 °C (295 K), T2 = 52 °C (325 K).

[tex]V_2=\dfrac{V_1T_2}{T_1}[/tex]V

[tex]V_2=\dfrac{1\times 325}{295}=1.1\ L[/tex]

Hence the final volume of the tire will be 1.1 L

Answer:

It goes through a process called absorption. This is when an atom absorbs the energy from its surroundings. The electrons move from the ground state to the excited state because of this process. Once the atoms absorb energy, that affects the inner development when shifting to a new state of being.

Explanation:

The process that is known as absorption is when an atom absorbs energy from its surrounding racing it's energy level causing it to go into an excited state or highly-reactive state. When an atom goes through this process, electrons absorb the energy and raise to higher energy levels, therefore raising the stage of itself. This is how it gets into a excited state.
