Explanation:

The molecular formula for Nickel (IV) Chloride will be NiCl₂. Nickel reacts with chloride to form a salt. The salt is yellow in color and anhydrous.

A molecular formula is a way of presentation of chemical formula of a compound. It gives the information related to the type of atoms, number of atoms which constitutes the compound and the chemical properties.

Molecular formula of a chemical compound can be derived by the valency of element. In this question, molecular formula of the compound can be derived by:

Valency of Nickel = 2

Valency of Chlorine = 1

By the cross-multiplication of valency:

element 1(valency of element 2). element 2 (valency of element 1)

= Ni (1). Cl(2)

= NiCl₂

Therefore, the molecular formula of Nickel (IV) chloride will be NiCl₂.

Answer:

They would be pushed out and lose their homes

Explanation:

A wildfire destroys most of the plant life in a forest. Animals would be pushed out and lose their homes.

An unplanned, uncontrolled, and unpredictable fire inside an area of flammable vegetation is known by several names, including wildfire, bushfire, bushfire, wildland fire, and rural fire. A wildfire may be more precisely referred to by the terms bushfire, desert fire, forest fire, hill fire, peatland fire, prairie fire, vegetable fire, or veld fire, depending on the kind of vegetation that is present.

Wildfires are separate from controlled and prescribed burning, which is a good human use of wildland fire, even though controlled burns have the potential to turn into wildfires. Wildfires likely started shortly after terrestrial plants first appeared, which occurred in the Silurian epoch 419 million years ago, according to fossil charcoal. A wildfire destroys most of the plant life in a forest. Animals would be pushed out and lose their homes.

Therefore, animals would be pushed out and lose their homes.

Explanation: It’s in my notes

The conjugate base is formed when an acid loses its hydrogen or proton. In the reaction between ammonium ion and hydrogen phosphate, HPO₄²⁻ is the conjugate base. Thus, option C is correct.

Conjugate bases are formed when the substance accepts or absorbs the proton or the hydrogen ion from the acids in the solution. It can be said as a base with an added hydrogen ion to it.

The chemical reaction of the acids and the bases has been shown as,

NH₄⁺ + HPO₄²⁻ → NH₃⁺ +  H₂PO₄⁻

From the reaction, it can be said that ammonia donated its proton, whereas HPO₄²⁻ accepted hydrogen ions from the acid.

Therefore, HPO₄²⁻ has been the conjugate base in the given chemical reaction.

Answer:

No, I don't think so at least

Explanation:

In chemistry, you do calculations to find the concentration of a solution with another solution of KNOWN concentration. Without concentrations of either solution, were would you get values from? Where would you start? :3

You can not titrate  a solution of unknown concentration with another solution of unknown concentration and still get a meaningful answer.

Titration involves the standardization of unknown solution using a standard solution. By this definition, titration must involve a standard solution.

Since the two unknown solutions are not standardized, we can never get a meaningful answer because we can not be able to perform any calculation unless we have a standard solution.

Explanation:

Explanation:

I think the question is not complete

Answer:

26.78 kJ

Explanation:

To solve the problem, we have to first write the stoichiometric coefficients in the chemical equation:

2P + 3Cl₂ → 2PCl₃

With these coefficients, we have the same number of atoms of each chemical element on both sides: 2 atoms of P, 6 atoms of Cl.

According to the equation, 2 moles of phosphorous (P) react with 3 moles of chlorine (Cl₂), and 574 kJ of energy are released. We have to figure out which is the limiting reactant. For this, we convert the mass into moles by using the molar mass(MM):

MM(P) = 30.9 g/mol

67.04 g P/(30.9 g/mol) = 2.17 mol P

MM(Cl₂) = 35.4 g/mol x 2 = 70.8 g/mol

10.20 g Cl₂/(70.8 g/mol) = 0.14 mol Cl₂

Now, we multiply the actual moles of P (the amount we have for the reaction) by the stoichiometric ratio given by the chemical equation (3 mol Cl₂/2 mol P):

2.17 mol P x (3 mol Cl₂/2 mol P) = 3.25 mol Cl₂

To completely react 67.04 g P, we need 3.25 mol of Cl₂, and we have only 0.14 moles of Cl₂, so the limiting reactant is Cl₂.

Now, we use the limiting reactant to calculate the energy released from the reaction. The energy released per mole of Cl₂ is:

ΔH/(3 mol Cl₂) = -574 kJ/3 mol Cl₂= 191.3 kJ/mol Cl₂

Finally, we multiply the energy released per mole of Cl₂ by the number of moles of Cl₂ we have:

0.14 mol Cl₂ x 191.3 kJ/mol Cl₂ = 26.78 kJ

Answer:

Number of moles = 0.075 mol

Explanation:

Volume = 500.0 mL = 0.5 (Converting to L by dividing by 1000)

Molarity = 0.15 M

Number of moles = ?

The relationship between the quantities is given as;

Molarity  = Number of moles / Volume

Number of moles = Molarity * Volume

Number of moles = 0.15  * 0.5

Number of moles = 0.075 mol

Answer:

C

Explanation:

If I am not mistaken, due to the conservation of mass, whatever mass is on the side of the reactants should be the same for the product side.

This means

218.76g+53.96g = 272.72g

272.72g-266.66g = 6.06g

So the answer should be C

Explanation:

This is because non point source of pollution refers to source of pollution that are many and not directly one which is illegal or does not meet the legal term. This type of pollution does not have a point source, it has many sources and this type of pollution is cause by rainfall or precipitation. Where when the rain fall, it wash away the waste through to water bodies, causing pollution and endangering water bodies.
