Explanation:

The balanced chemical equation will be Ca + MgCl2 → CaCl2 + Mg.

An equation that has the same quantity of atoms on both sides of the arrow would be said to represent a balanced chemical reaction.

The given equation is Ca + MgCl2 →

It is known that when Ca is reacted with magnesium chloride ( MgCl2) then it will form calcium chloride (CaCl2 ) and magnesium.

Ca + MgCl2 → CaCl2 + Mg.

It can be seen that, calcium has one atom in the reactant side and one atom in product side. On the other hand, chlorine has one atom in reactant side as well as product side.

Hence, the reaction will be balanced.

The final temperature of the sample of gas is 689.65 Kelvin.

Relation between the temperature and pressure will be represented by the ideal gas equation PV = nRT, and for this question required equation is:

P₁/T₁ = P₂/T₂, where
P₁ & T₁ are the pressure and temperature of the initial sample.

P₂ & T₂ are the pressure and temperature of the final sample.

Pressure is in mmHg and on putting values from the question on the above equation, we get

T₂ = (810)(390.8) / (760) = 416.5 degree C = 689.65K

Hence required temperature of the sample is 689.65K.

Explanation:

If you think of a  heating or cooling curve, even when there isn't a phase change, the kinetic energy of the particles is still changing.

Grams are the unit of measurement of the mass or the weight of the substance. There are 1.17 gms of chlorine atoms in the sample.

The mass of the substance is the multiplication of the moles and the molar mass.

Barium chloride dissociates as:

BaCl₂ ⇄  Ba²⁺ + 2 Cl⁻

From the reaction, it can be said that 1 mole of barium chloride dissociates into 1-mole barium ion and 2 moles of chloride ions.

Moles of barium chloride are calculated as:

Moles = mass ÷ molar mass

= 3.45 gm ÷ 208.23 g/mol

= 0.016 moles

If 1 mole of Barium chloride has 2 moles then 0.016 moles of the sample will have, 0.0331 moles of chloride ions.

The mass of chlorine atoms is calculated as:

Mass = moles × molar mass

= 0.0331 × 35.45

= 1.17 gms

Therefore, 1.17 gms of chlorine atoms are present in barium chloride.

Explanation:

Manganese metal is produced from the manganese(III) oxide, Mn2O3, which is found in manganite, a manganese ore. The manganese is reduced from its +3 oxidation state in Mn2O3 to the zero oxidation state of the uncharged metal by reacting the Mn2O3 with a reducing agent such as aluminum or carbon. How many pounds of manganese are in 1.261 tons of Mn2O3? (1 ton = 2000 pounds)

About 40 different substances called organophosphorus compounds are registered in the United States as insecticides. They are considered less damaging to the environment than some other insecticides because they breakdown relatively rapidly in the environment. The first of these organophosphorus insecticides to be produced was tetraethyl pyrophosphate, TEPP, which is 33.11% carbon, 6.95% hydrogen, 38.59% oxygen, and 21.35% phosphorus. It has a molecular mass of 290.190.

A quantity can be converted from one unit of measurement to another while maintaining its value. There are 2522 pounds of manganese in 1.261 tons of [tex]\rm Mn_2O_3[/tex].

It is a fundamental idea that is applied in many different disciplines such as science, engineering, math and daily life. To complete a conversion, it is necessary to know the conversion factor – the numerical relationship between the two units of measurement. With the help of this factor, you are able to convert units while keeping the value constant.

To convert tons to pounds we need to know that 1 ton is equal to 2000 pounds.

Given that you have 1.261 tons of [tex]\rm Mn_2O_3[/tex], we can calculate the number of pounds as follows:

Number of pounds = 1.261 tons * 2000 pounds/ton

Number of pounds = 2522 pounds

Therefore, there are 2522 pounds of manganese in 1.261 tons of [tex]\rm Mn_2O_3[/tex].

Molar mass is the summation of the atomic mass of the individual atoms. The molar mass of KBr•7H₂O is 244.99.

Atomic mass or weight is the number of protons and neutrons in the atom of the individual element. The atomic masses are used to calculate the molar mass of the compound.

The compound KBr•7H₂O: 1 K + 1 Br + 14 H + 7O

Inserting the atomic masses of the individual atoms as:

= 1 (39.09) + 1 (79.90) + 14 (1.00) + 7(16)

= 39.09 + 79.90 + 14.00 + 112

= 244.99

Answer:

0.0734 grams LiOH

Explanation:

The molarity formula looks like this:

Molarity (M) = moles / volume (L)

You are given the molarity and volume (in mL). Therefore, you can plug these values into the equation and solve for moles (after you convert from mL to L).

25 mL / 1,000 = 0.025 L

0.125 M = moles / 0.025 L

(0.125 M) x (0.025 L) = moles

0.003125 = moles

After using the molarity formula, we know that 0.003125 moles LiOH are needed to satisfy these conditions. Now, we can convert this to grams using the molar mass of LiOH. This can be determined using the values from the periodic table. Remember to write your conversion in a way that allows for the units to cancel out.

Molar Mass (LiOH) = 6.941 g/mol + 16.00 g/mol + 1.008 g/mol

Molar Mass (LiOH) = 23.499 g/mol

0.003125 moles           23.499 g
------------------------   x   -------------------  =  0.0734 grams LiOH
                                        1 mole

0.074 grams of lithium hydroxide are needed to make 25 ml of 0.125 M solution, according to the concept of molar concentration.

Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.

The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.

In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.

Here , in the problem mass is to be determined, hence the formula used is the first one mentioned.

Substituting values in the formula,mass=molar concentration×molar mass×volume in liters

∴0.125×23.95×0.025=0.074 g.

Hence, 0.074 g of lithium hydroxide are required to prepare 25 ml of 0.125 M solution.

The answer is 0.46 ml of the original H₂S0₄ and dilute to a final volume of 100 ml.

Normality is a measure of concentration equal to the gram equivalent weight per liter of solution.

Normality = Number of gram equivalents × [volume of solution in litres]⁻¹

Preparing 100. ml of 0.1 N H₂S0₄

Eq. wt. of H₂S0₄ = 98/2=49

density of H₂S0₄= 1.08

Purity =98%

1 N H₂S0₄ = 49 gH₂S0₄ / liter

1  gm equiv wt /L x 1 gm equiv. wt / 2 = 98 / 2 = 49 g)

0.1 N H2SO4 = 4.9 g / L

To make 100 ml (0.100 L) we would need 4.9 [tex]\rm \frac{g}{L}[/tex] x 0.1 L

= 0.49 g H₂S0₄/100ml

Original density = 1.08 g / ml

with a purity of 98%,

this converts to 1.08 g x 0.98 = 1.058 g /ml

0.49 g H₂S0₄ x 1 ml / 1.058 g = 0.46 ml of original H₂S0₄needed

Therefore to make the desired solution

Take 0.46 ml of the original H₂S0₄ and dilute to a final volume of 100 ml.

The required formula of hydrate is MgSO₃.6H₂O.

The number of moles of water per mole of anhydrous solid (x) will be computed by dividing the number of moles of water by the number of moles of anhydrous solid (x) to find the hydrate's formula.

Moles will be calculated as:
n = W/M, where

Moles of MgSO₃ = 0.737g / 104.3g/mol = 0.007mol

Moles of H₂O = 0.763g / 18g/mol = 0.04 mol

Number of H₂O molecule = 0.04/0.007 = 5.7 = 6
