Answer:

Chemical to electrical to mechanical

Explanation:

The energy conversion going on in a battery - powered toy car is from chemical to electrical and then to mechanical energy.

According to the law of conservation of energy, energy is neither created nor destroyed but transformed from one form to another.

The concept combined gas equation is used here to determine the final temperature of the gas. These laws relate one thermodynamic variable to another holding everything else constant.

The combination of Boyle's law, Charles's law and Gay - Lussac's law give rise to the combined gas law. The state of a gas is determined by the macroscopic and microscopic parameters like pressure, volume, temperature, etc.

The combined gas equation is:

P₁V₁ /T₁ = P₂V₂ /T₂

T₂ = P₂V₂T₁ / P₁V₁

T₁ = 45 + 273 = 318 K

T₂ = 49.5 × 6.50 × 318 / 89.5 × 3.5 = 326.62 K

Half-reactions are often used as a method of balancing redox reactions. For oxidation-reduction reactions in acidic conditions, after balancing the atoms and oxidation numbers, one will need to add H + ions to balance the hydrogen ions in the half reaction.

Explanation:

Answer:

We can use the half-reaction method to balance the equations of redox reactions occurring in aqueous solution. ... Each half-reaction is balanced for mass and charge, and then the two equations are recombined with appropriate coefficients so that the electrons cancel.

Answer:

The correct answer will be "-6.7 × 10¹⁰ kg.m/s".

Explanation:

The required conversions are:

⇒  \(1 \ kg=1000 \ g\)

⇒  \(1 \ m=100 \ cm\)

Now,

The complete conversion will be:

=  \([-6.7\times 10^5 \ \frac{kg \ m}{s} ]\times [\frac{10^3 \ g}{kg}\times \frac{10^2 \ cm}{1 \ m}]\)

On cancelling the terms, we get

=  \(-6.7\times 10^{10} \frac{kg \ m}{s}\)

So that the missing terms will be \([\frac{10^3 \ g}{kg}\times \frac{10^2 \ cm}{1 \ m}]\) and \([-6.7\times 10^{10}\frac{kg \ m}{s}]\)

Based on the Law of Conservation of Mass, the mass of products form when baking soda decomposes is 168 g/mole.

The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

From the equation of NaHCO3 → Na₂CO3 + H₂O + CO₂ , we have

Mass of baking soda = 2 x molar mass

Molar mass of NaHCO₃ = 84.007 g/mole

Mass of baking soda = 2 x 84.007 g/mole

Mass of baking soda =  168.014 g/mole=  168 g/mole

Therefore, based on the Law of Conservation of Mass, the mass of products form when baking soda decomposes is 168 g/mole.

Answer:

Explanation:

The balanced chemical equation for the reaction between calcium and nitrogen gas to form calcium nitride is:

3Ca + N2 → Ca3N2

From the balanced equation, we can see that the mole ratio between calcium and calcium nitride is 3:1. This means that 3 moles of calcium react to form 1 mole of calcium nitride.

First, let's calculate the number of moles of calcium and nitrogen gas given:

Mass of calcium = 56.6 g

Molar mass of calcium (Ca) = 40.08 g/mol

Moles of calcium = Mass of calcium / Molar mass of calcium = 56.6 g / 40.08 g/mol = 1.41 mol

Mass of nitrogen gas = 30.5 g

Molar mass of nitrogen gas (N2) = 28.02 g/mol

Moles of nitrogen gas = Mass of nitrogen gas / Molar mass of nitrogen gas = 30.5 g / 28.02 g/mol = 1.09 mol

Since the reaction has a 90% yield, only 90% of the limiting reactant (which is calcium in this case) will be converted to product. Therefore, we need to multiply the moles of calcium by 0.90 to account for the yield:

Moles of calcium nitride formed = Moles of calcium x Yield = 1.41 mol x 0.90 = 1.27 mol

Now, using the mole ratio from the balanced equation, we can determine the mass of calcium nitride formed:

Molar mass of calcium nitride (Ca3N2) = 40.08 g/mol (molar mass of calcium) x 3 + 14.01 g/mol (molar mass of nitrogen) x 2 = 120.25 g/mol

Mass of calcium nitride formed = Moles of calcium nitride formed x Molar mass of calcium nitride = 1.27 mol x 120.25 g/mol = 152.57 g

So, the mass of calcium nitride formed in the reaction is 152.57 g.

The molar mass of phosphorus chloride is 137.88 g/mol

Explanation:

Step 1: Data given

Mass of phosphorus = 2.46 grams

Its vapor took 1.77 times as long to effuse as the same amount of CO2 under the same conditions of temperature and pressure.

Step 2:

t1/t2 = √(M1/M2)

⇒with t1 = the time phosphorus chloride needed to effuse = 1.77t

⇒with t2 = the time CO2 needed to effuse = 1t

⇒with M1 = the molar mass of phosphorus chloride = TO BE DETERMINED

⇒with M2 = the molar mass of CO2 = 44.01 g/mol

1.77t / 1t = √(M1/44.01)

1.77 = √(M1/44.01)

3.1329 = M1 / 44.01

M1 = 3.1329 * 44.01

M1 = 137.88 g/mol

The molar mass of phosphorus chloride is 137.88 g/mol

     (  (88.5 -50 C)*1.45 J / (mole-C)      <====heating the liquid

               +  1230 J / mole                              <====boiling to a gas

The amount of heat can be calculated from the expression of heat capacity using heat of fusion and molar mass of benzene.

159g of benzene is heated from the temperature of 53.7C.

Molar mass of benzene,C6H6= 78.11236 g/mol.

heat capacity of benzene, C6H6= 1.63 J/ G. K

The heat of fusion = 9.87 KJ / mol.

Heat of fusion is the change in its enthalpy resulting from providing energy, typically heat, to a specific quantity of the substance to change its state from a solid to a liquid at constant pressure.

Energy used in melting the solid(in JOULES) = (mass of benzene/molar mass of benzene) × heat of Fusion.

           = (159 g/ 78.11236 G/ mole ) × 9.87 kJ per mol.

           = 20.090 J

           = 0.002009 KJ

Heat capacity is also known as thermal capacity. It is a physical property of matter defined as the amount of heat to be supplied to an object to produce a unit change in its temperature

Energy= heat capacity (J/ G.K) × mass of benzene× (∆T).

           = 1.63 J/GK × 159g× 53.7

Answer:

\(\huge\boxed{\sf CNH_4}\)

Explanation:

Given compound us,

C₂N₂H₈

= 2 : 2 : 8

= 2 ÷ 2 : 2 ÷ 2 : 8 ÷ 2

= 1 : 1 : 4

So, we can write the formula as:

\(\rule[225]{225}{2}\)

(i)Until a new equilibrium is reached, the amounts of reactants (CH₄ and H₂S) will rise while the amounts of CS₂ will fall. (ii)The equilibrium position will move to the right, causing the concentrations of CS₂ and H₂ to rise while those of CH₄ and H₂S will drop. (iii)Altering the pressure won't have an immediate impact on the equilibrium position.

Le Chatelier's principle must be taken into account in order to comprehend the variations in the equilibrium position and the quantities of reactants and products. According to this theory, if a system that is in equilibrium experiences a change in the environment, the system will adapt to deal with the change and find a new equilibrium position.

(i)Le Chatelier's principle states that adding more of a product (in this case, CS₂) will cause the equilibrium position to move to the left in order to offset the change. As a result, until a new equilibrium is reached, the amounts of reactants (CH₄ and H₂S) will rise while the amounts of CS₂ will fall.

(ii)If the temperature were raised: The reaction in question is endothermic since it needs heat to produce CS₂ and H₂. Le Chatelier's principle states that when the temperature of an endothermic process is raised, the production of products to absorb the additional heat is encouraged. As a result, the equilibrium position will move to the right, causing the concentrations of CS₂ and H₂ to rise while those of CH₄ and H₂S will drop.

(iii). If the pressure were raised: In the reaction that is being described, there are exactly two moles of gas on each side. As a result, altering the pressure won't have an immediate impact on the equilibrium position. Changes in pressure, however, may affect the reaction if any of the

Changes in pressure won't have a direct impact on the equilibrium position because the provided reaction has the same number of moles of gas on both sides. Changes in pressure could nonetheless have an indirect effect on the reaction if any species are in a changed physical state.
