How many grams of O2 are made if 2.90 moles of potassium chlorate react based on the same unbalanced equation below

During the course of a catalytic reaction Substrate is covalently bound and oriented with proximity to the active site residues.

The type of chemical species which can facilitate these reactions is transition metal cations.

These are proteins that act as biological catalysts and accelerate chemical reactions.

They function by binding to the substrate and requires the use of transition metal cations which acts as cofactors.

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

A radioactive element has a half-life of six days then the approximate decay rate of the element after the first day is 8.3%.

Half life time is that time during which half of the concentration of reactant will changed into the product.

According to the question:

In 6 days = 50% of the reactant will change into product

In 1 day = 50%/6 of the reactant will change into product

So, in 1 day = 8.3% of the reactant will change into product

Hence option (3) is correct.

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%.

Explanation:

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 .

Explanation:

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.

Explanation:

Aquatic life- animals living in water use up dissolved oxygen.

Elevation- the amount of oxygen in elevation increases.

Salinity- Salty water holds less oxygen than fresh water.

Temperature- cold water holds more dissolved oxygen than warm water.

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.

Answer: I believe the answer is surface tension :)

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.

Answer:

Your answer would be:
D.) Weathering breaks parent material into smaller pieces.

Explanation:

Weathering breaks down and loosens the surface minerals of rock. The broken rocks are transported to another place where it decomposes and forms soil. Therefore weathering is important for soil formation. Without it, there will be likely less soil.

Explanation:

The loss of crystaline structure of sucrose was reported at various temperatures, but decompose.

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
