1.47 J/g°C is the specific heat capacity of a 70 g sample of an unknown metal that releases 6700J of heat when it cools from 90 to 25 degrees C.

The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases by 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).

q = mCpΔT

Solve for Cp —> Cp = q/mΔT

q = -6700 J (negative because it released heat)

m = 70 g

ΔT = Final temp - initial temp = 25 - 90 = -65°C

Cp = (-6700 J) ÷ (70 g)(-65°C)

= 1.47 J/g°C

Hence, 1.47 J/g°C is the specific heat capacity of a 70 g sample of an unknown metal that releases 6700J of heat when it cools from 90 to 25 degrees C.

Ca(OH)2 molecular weight. Molar mass of Ca(OH)2 = 74.09268 g/mol. This compound is also known as Calcium Hydroxide. Convert grams Ca(OH)2 to moles or moles Ca(OH)2 to grams. Molecular weight calculation: 40.078 + (15.9994 + 1.00794)*2 ››

Hey,

A) Let's first calculate the molar mass M of the molecule :

M(Ca(OH)₂) = M(Ca) + 2M(O) + 2M(H)

B) Let's deduct the corresponding mass m :

m = M x n

The mass of calcium hydroxide corresponding to this quantity of substance (in mol) is therefore 34 g.

Answer:

575 g

Explanation:

1 kg of sodium hydroxide is 1000/40=25 mol.

So 25 mol of sodium will be needed.

25 mol of sodium is 575 g.

According to the stoichiometry of the given chemical equation, 575 g s of sodium would be needed to produce 1.00 kg of sodium hydroxide.

Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.

A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .

The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

46 g sodium gives 80 g sodium hydroxide, thus 1000 g sodium hydroxide requires 46×1000/80=575 g sodium.

Thus, 575 g s of sodium would be needed to produce 1.00 kg of sodium hydroxide.

Reduction

Explanation:

Oxidation is a process that involves loss of electrons.

Reduction is a process that involves gain of electrons.

In this equation, the electrons (4e-) are in the reactant side. This means that it is gain of electrons.

The reaction is a reduction reaction.

Answer:

2.5 mole O2 should react (2 * 2.5) = 5.0 mole H2 but there is 6.0 mole H2. H2 remain in excess. O2 is the limiting reactant. mole of H2O formed = 2 * 2.5 = 5.0 mole.

Moles of water are produced when 6.0 moles of hydrogen gas react with 2.5 moles of oxygen gas

Balanced equation: 2H2 + O2 → 2H2O

2.5 mole O2 should react (2 × 2.5) = 5.0 mole

H2 but there is 6.0 mole H2.

H2 remain in excess. O2 is the limiting reactant.

mole of H2O formed = 2 × 2.5 = 5.0 mole.

= 5.0 mole

If less than 6 moles of oxygen are available per mole of glucose, oxygen is the limiting reactant. The ratio is 6 mole oxygen per 1 mole glucose, OR 1 mole oxygen per 1/6 mole glucose.

Increasing the surface area, stirring or agitating the mixture, raising the solvent's temperature, and employing a solvent with a stronger polarity or one that is more similar to the solid's chemical makeup are all ways to speed up the dissolving process.

There are several methods that can increase the rate of dissolving a solid, including:

Increasing the surface area of the solid by crushing, grinding or pulverizing it into smaller pieces.

- Stirring or agitating the mixture, which helps to distribute the solvent and increase contact between the solvent and the solid.

- Increasing the temperature of the solvent, which increases the kinetic energy of the solvent molecules, making them more likely to collide with and dissolve the solid.

- Using a solvent that has a higher polarity or is more similar in composition to the solid, which can increase the attraction between the solvent and the solid and promote faster dissolving.

Therefore, the methods that would increase the rate of dissolving a solid are increasing surface area, stirring or agitating the mixture, increasing the temperature of the solvent, and using a solvent that has a higher polarity or is more similar in composition to the solid.
