Explanation:

Hello there!

In this case, by considering the definition of molar solution as the moles of solute over volume in liters or cubic meters of solution, we can see that actually 10.0 L of the solution are equal to 10.0 dm³. In such a way, since the concentration is 0.001 mol / dm³, the moles of oxygen that are dissolved turn out to be:

[tex]0.001mol/dm^3 * 10.0dm^3\\\\0.01molO_2[/tex]

Answer:

Id say the third one

Explanation: chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.

thats the only one that is close to definition

Answer:

yes

Explanation:

its an endothermic chemical reaction

Answer:

It is a chemical reaction because you cannot get back the original ingredients. if you can get the original ingredients back, it would be a physical change.

Hope this helped you out!!

Answer:

True

Explanation:

The correct option is - True

Answer:

I think it is covalent bonding...

Explanation:

The bonding is covalent in homonuclear diatomic molecules. Each atom in the molecule has the same electronegativity, which means electrons are shared equally between the two. The electronegativity of the atoms in heteronuclear diatomic molecules varies, and these molecules have polar covalent bonds. A dipole is formed when a molecule interacts with another molecule. (i think it's covalent bonding but i might be wrong)

Answer:

D. Grass​

Explanation:

Every living organism must contain one or more cells to be considered "living". Each cell, however, contains certain structures that perform specific roles called ORGANELLES. These organelles are of different types and hence, perform different tasks. For example, mitochondria is the power house of a cell i.e. site of energy production, and hence, is found in every eukaryotic cell.

On the other hand, chloroplast is an organelle designed to perform photosynthesis, which only occurs in plant cells. Since only plant cells can undergo photosynthesis, only plant cells can contain chloroplast. Hence, according to this question, GRASS as a type of plant is an organism that will contain both mitochondria and chloroplast in its cells.

Answer:

ΔG = -24.7kJ/mol

Explanation:

ΔG° of

Pb2+(aq) + 2Br-(aq) ⇄ PbBr2(s)

is:

ΔG° PbBr2 - (2*ΔG°Br- + ΔG°Pb2+)

-261.9kJ/mol - (2*-104.0kJ/mol + -24.4kJ/mol) =  

-29.5kJ/mol

ΔG of the reaction is:

ΔG = ΔG° + RT lnQ

Where R is gas constant (8.314x10⁻³kJ/molK)

T is absolute temperature (20°C + 273.15 = 293.15K)

Q is reaction quotient = 1 / [Pb²⁺][Br⁻]²

Replacing:

ΔG = -29.5kJ/mol + 8.314x10⁻³kJ/molK*293.15K ln(1 / [Pb²⁺][Br⁻]²)

ΔG = -29.5kJ/mol + 8.314x10⁻³kJ/molK*293.15K ln(1 / [0.247M][0.758M]²)

The statement concerning the length of carbon-carbon single, double, and triple covalent bonds which is true is: D. The carbon-carbon single, double, and triple bonds all have the same length.

A chemical bond can be defined as the forces of attraction between ions, crystals, atoms or molecules which are typically responsible for the formation of chemical compounds. Thus, a chemical bond is a force that holds atom together and binds crystals, ions or molecules together, so as to form a chemical compound.

Generally, there are three (3) main types of chemical bonds and these includes:

A covalent bond can be defined as a type of bond that typically involves the sharing of electrons between the atoms of a chemical element. The type of bond formed between two or more carbon atoms is a covalent bond. Hence, carbon atoms can either form a single, double, or triple covalent bonds with the same length.

In conclusion, the length of carbon-carbon single, double, and triple covalent bonds are all the same.

Answer:

How many grams of K2Cr2O7, are soluble in 100 g of water at 95 ºC? Solubility Curve DRAFT. 10th - 12th grade. 3326 times. Chemistry. 63% average accuracy. 3 years ago ... When 20 grams of potassium chlorate, KClO 3, is dissolved in 100 grams of water at 80 ºC, the solution can be correctly described as: answer choices . supersaturated. saturated.

Explanation:

Answer: The maximum amount of water that can be produced is 0.74 g

Explanation:

To calculate the number of moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex]      .....(1)  

Putting values in equation 1, we get:

[tex]\text{Moles of hydrochloric acid:}=\frac{1.5g}{36.5g/mol}=0.041mol[/tex]

[tex]\text{Moles of sodium hydroxide}=\frac{2.67g}{40g/mol}=0.067mol[/tex]

The chemical equation for the reaction is

[tex]HCl+NaOH\rightarrow NaCl+H_2O[/tex]

By Stoichiometry of the reaction:

1 mole of HCl reacts with 1 mole of NaOH

So, 0.041 moles of HCl will react with = [tex]\frac{1}{1}\times 0.041=0.041mol[/tex] of NaOH

As, given amount of NaOH is more than the required amount. So, it is considered as an excess reagent. Thus, HCl is considered as a limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

1 mole of HCl produces = 1 mole of water

So, 0.041 moles of HCl will produce = [tex]\frac{1}{1}\times 0.041=0.041moles[/tex] of water

Mass of water=[tex]moles\times {\text{Molar Mass}}=0.041mol\times 18g/mol=0.74g[/tex]

Thus the maximum amount of water that can be produced is 0.74 g

Answer:

[OH-] = 1.8 x 10^-12 M

Explanation:

Kw = 1.0 x 10^-14

[OH-] = 1.0 x 10^-14 / 0.0056 = 1.8 x 10^-12 M

Answer:

b. NH3(aq) does not contain OH- ions.

Explanation:

According to Arrhenius in his definition, a base is a substance that has the ability to increase the hydroxyll ion (OH-) of an aqueous solution. In other words, Arrhenius bases dissociates into OH- when dissolved in water.

According to this question, ammonia (NH3) will not be considered an Arrhenius base because it does not contain OH-. This means that ammonia (NH3) cannot dissociate into hydroxyll ion when dissolved in water.

Answer:

See explanation

Explanation:

a) Every substance melts at a particular temperature known as the melting point of the substance. The melting point of ice is 0°C. Hence ice melts at  0°C.

b) There are three states of matter; solid liquid and gas. The particles of matter in each stage of matter possess varying degrees of freedom.

In the solid state, the intermolecular forces between the particles of water that compose ice are very strong. Hence the particles do not translate, they only vibrate or rotate about their mean positions.

In the liquid state, the magnitude of intermolecular interaction is less than that of the solids hence the molecules can translate but not with a high kinetic energy.

In the gaseous state, there is a minimum intermolecular interaction between particles theoretically hence the particles are really free to move about with a very high kinetic energy.
