Answer:

1. B. Ammonia and hexane will not dissolve because one molecule is polar and the other is non polar.

2. 1400 mL

Explanation:

In chemistry, like dissolve like! Ammonia is a polar molecule having a significant dipole moment owing to its three N-H bonds. On the other hand, hexane is a purely non-polar hydrocarbon hence the two substances can never dissolve in each other.

From the dilution formula;

C1V1=C2V2

C1= Initial concentration of the solution

V1 = Initial volume of the solution

C2 = Final concentration of the solution

V2= Final volume of the solution

2.8 M * 750.0 mL = 1.5 M * V2

V2 = 2.8 M * 750.0 mL/1.5 M

V2 = 1400 mL

Hello Mistyann!

First you need to know amount of barium phosphate is

Half of potassium phosphate, also 2.18 mol.

Molar mass of Barium phosphate is 3·137.2 + 2·(30.97+4·16) g/mol

You can calculate it yourself dear.

Now mass is amount of substance · molar mass.

It has been an honour to teach you, dear,

God bless!

Explanation:

Answer: 0.16 g H2

Explanation:

Mg+ H2SO4= MgSO4 + H2

Atomic massof Mg is 24

Molecular mass of H2 is 2

So,

24g Mg produce 2 g H2

1g Mg produce (2÷24)= 0.083 g H2

2.00g Mg produce (0.083×2) g H2

   = 0.16 g H2

 0.16g of hydrogen is formed when 2.00g of magnesium.

The mass of hydrogen gas formed when 2.00g of magnesium is equal to 0.165 g.

The chemical equation of a reaction is said to be a balanced equation when the number of atoms of substances is equal on either side of the equation.

Evergy balanced chemical equation must follow the law of conservation of mass according to which the total mass of the substances present on the reactant side should be equal to the total mass of substances present on the product side.

Given, the balanced chemical equation of the reaction of Mg and sulfuric acid:

[tex]Mg + H_2SO_4 \longrightarrow MgSO_4 +H_2[/tex]

One mole of magnesium produces hydrogen gas = 1mol

Given the mass of magnesium = 2g

The number of moles of Mg = 2/24.3 = 0.082 mol

Then the number of moles of hydrogen gas formed = 0.082 mol

The mass of the hydrogen gas = 0.082 × 2 = 0.165 g

Answer:

In the middle of the forest.

Explanation:

They have to bury the remains in the middle of the forest at the Forensic Osteological Research Center in order to study the decomposition of the dead person. By studying the decomposition of dead person we can get a lot of information which can be used in the study of criminal cases and solving of crimes. The middle place in the forest is a perfect place to bury the remains due to presence of huge amount of microbes as well as insect that helps in the decomposition.

Answer: the answer is 12M

Explanation: 3.0mol/ 0.25L =12M

12M is the molarity of a solution made from dissolving 3.0 moles of Saline (NaCl) in 0.25 L of solution.

The amount of molecules of molecules divided by the quantity of liters in solution is the definition of molarity, a concentration unit in chemistry. It is crucial to comprehend how it is calculated as well as when to employ it in comparison to other units because it is among the most widely used concentration units.

A chemical solution's concentration is measured in molarity (M). It refers to the solute's moles per liter of solution. To be clear, this is not the same as the liters of solvents (a common mistake).

molarity = number of moles of solute/ volume of solution in litre

molarity =3.0mol/ 0.25L

             =12M

Therefore, 12M is the molarity of a solution made from dissolving 3.0 moles of Saline (NaCl) in 0.25 L of solution.

Answer:

Dividing the mass of the water lost by the original mass of hydrate used is equal to the fraction of water in the compound. Multiplying this fraction by 100 gives the percent water in the hydrate.

Explanation:

The amount of water throughout the compound has been determined by dividing the mass of water wasted mostly by original quantity of hydrate used. The above fraction can be multiplied by 100 to get the hydrate's water content in percentages.

The proportion of matter that makes up an object is quantified by its mass. The kilogram, or kg, would be the fundamental SI unit of mass.

Any substance that contains water through the form of H2O molecules is referred to as a hydrate. This water content by weight can vary, but it is typically fixed. The most well-known hydrates seem to be crystalline solids which decompose once the attached water is removed.

Therefore , The amount of water throughout the compound has been determined by dividing the mass of water wasted mostly by original quantity of hydrate used. The above fraction can be multiplied by 100 to get the hydrate's water content in percentages.

Answer:

Explanation:  A conversion factor is a number used to change one set of units to another, by multiplying or dividing. When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equal 1 foot.

Molality = moles of solute/mass (in kg) of solvent

The solute here is NaCl, of which you have 40 g or 40/58.4428 = 0.6844 moles NaCl.

The solvent here is water, of which you have 1500 g or 1.500 kg H2O.

The molality of the resulting solution would thus be 0.6844 moles NaCl/1.500 kg H2O = 0.4562 mol/kg.

If you have to consider sig figs, then your final answer would have one sig fig (40 g has one sig fig). In that case, your final answer would be 0.5 mol/kg.

The theoretical yield is 6 sapphire rings.

This is the total product formed as a result of the complete conversion of

the reactants. In this scenario, the reactant is the 12 sapphires in which 2

of it is needed to produce one sapphire ring.

This however translates to the theoretical yield being 6 sapphire rings

which is gotten by:

2 sapphires = 1 ring

12 sapphires = x

Cross multiply
