Answer:

it indicates, how many atoms or ions of each type are combined in the simplest unit.

Based on the data shown in the graph, the rate of reaction is directly proportional to the temperature of a reaction.

The speed at which a chemical reaction occurs is called the reaction rate or rate of reaction. The rate of a reaction is proportional to the increase in product concentration per unit time and the decrease in reactant concentration per unit time.

The rate of a reaction is affected by the following:

the temperature of the reaction - the rate of reaction is directly proportional to the temperature of a reaction. Hence, the rate of a reaction increases with an increase in temperature.

presence of a catalyst - the rate of a reaction increases with the addition of a catalyst. A catalyst speeds up the rate of a reaction.

the surface area of the reactants - the rate of a reaction increases with an increase in the surface area of the reactants,

Answer:

Attached picture.

Explanation:

(1) Ksp equals the product of [Co 2+][CO3 2-]. CoCO3 is excluded from the equilibrium expression because it is a pure solid. The mole ratio of Co 2+ and CO3 2- is 1:1 so their molar solubilities are the same.

(2) There is an initial concentration of 0.10 M Co 2+ so write that in the "I" row for Co 2+ on the ICE table. When you find the zeros of the quadratic when solving for "s", take the positive value rather than the negative value because concentration cannot be negative.

(3) Extra products will cause the equilibrium to consume products and form reactants. So the reverse reaction will occur faster than the forward reaction. More products mean an increased Q value compared to K, since the numerator of \(K = \frac{[products]}{[reactants]}\) increases.

The molar DeltaE in the reaction is 213.8 kJ/mol. A bomb thermometer is a device that is mostly used to measure combustion temperatures

With this method, a sample is burned in a bomb calorimeter at a constant volume. Equation q = -CΔT, where C is the calorimeter's heat capacity and ΔT is the temperature change, can be used to determine how much heat is released during the reaction.

We have to calculate the energy transferred,

q = CΔT

q = energy transferred

C = heat capacity of the calorimeter

ΔT is the temperature increase

q = 5,277 J/°C × 11.13°C = 58,765 J

Now,

Energy per mole of methanol = Energy transferred / Number of moles of methanol

Number of moles of methanol = Mass of methanol / Molar mass of methanol

Number of moles of methanol = 8.81 g / 32.04 g/mol = 0.2748 mol

Energy per mole of methanol = 58,765 J / 0.2748 mol = 213,772.8 J/mol

Now, we have to convert the energy per mole of methanol to kJ/mol:

Energy per mole of methanol = 213,772.8 J/mol / 1000 J/kJ = 213.8 kJ/mol

A heat capacity minus A temperature loss equals B heat capacity minus B temperature gain 9.56 °C

Object A is hotter than Object B, and since they are in direct contact, heat can be conducted between them. The conservation of energy principle states that energy cannot be created or destroyed. The energy that item A expends in this situation can only be transferred to object B.

To calculate the amount of energy transmitted, multiply the heat capacity by the degrees of temperature increase or drop, assuming that the mass of both items is the same. Below is the calculation:

Energy acquired by B = Energy lost by A

A heat capacity minus A temperature loss equals B heat capacity minus B temperature gain.

\(4.37J/degree C * 6.3 C= 2.88 J * TbTb= \frac{(4.37 J/ degree C * 6.3 C) }{ 2.88J}Tb= 9.56 degree C\)

At pOH value  of 6.0 the pH value of the following solution is 8.0 and the concentration of [\(H^{+}\) ] ion is \(10^{-8}\)

In this question we will apply the formula

      pH +pOH = 14 . . . . . . . . . . . . .(1)

where pH = concentration of [\(H^{+}\) ] ion

pOH = concentration of [\(OH^{-}\) ] ion

As per the question

pOH =6.0

Putting the value of pOH in equation (1) we get the value of pH

              pH + 6.0 =14

             pH = 14 -6.0

             pH  = 8.0

 The value of pH if the pOH value is 6.0 is 8.0

To find the concentration of \(H^{+}\) ion we will use the following formula

This is calculated by the formula

                                 [\(H^{+}\)} = \(10^{-pH}\)

where we will write the values of pH

Answer: metal turn orange and weaker as it gets oxidised

Explanation:

Mass of Sample = 59.993 - 57.880 = 2.113 g

Mass of Sample after 1st Heating = 59.710 - 57.880 = 1.83 g

Mass of Water Removed = 2.113 - 1.83 = 0.283 g

Mass of Sample after 2nd Heating = 59.7 - 57.88 = 1.82 g

Mass of Water Removed = 1.83 - 1.82 = 0.01 g

Total Mass of Water lost = 0.293 g

Moles of Water lost = 0.293 / 18 = 0.01628

Mass of Anhydrate = 1.82 g

Now check the molar mass of each hydrate:

Answer: 2.50 x 10^23 atoms of titanium correspond to 0.415 moles of titanium.

Explanation:

The question requires us to calculate the number of moles of titanium (Ti) that correponds to 2.50 x 10^23 atoms of Ti.

We can apply the Avogadro's number to solve this problem: according to this proportionality constant, there are 6.022 x 10^23 particles in 1 mol of any compound (particles can be atoms, ions, molecules etc).

Thus, considering the Avogadro's number, we can write:

6.022 x 10^23 atoms Ti -------------------- 1 mol Ti

2.50 x 10^23 atoms Ti ---------------------- x

Solving for x, we'll have:

Therefore, 2.50 x 10^23 atoms of titanium correspond to 0.415 moles of titanium.

Answer:

985.2 moles of nitrogen can produce 1970.4 moles of ammonia.

Explanation:

The balanced chemical equation for the production of ammonia from nitrogen is:

N2 + 3H2 → 2NH3

From the balanced equation, we can see that 1 mole of nitrogen reacts with 3 moles of hydrogen to produce 2 moles of ammonia.

So, to determine how many moles of ammonia can be produced from 985.2 moles of nitrogen, we need to use the mole ratio from the balanced chemical equation as follows:

985.2 moles N2 x (2 moles NH3 / 1 mole N2) = 1970.4 moles NH3

Therefore, 985.2 moles of nitrogen can produce 1970.4 moles of ammonia.

Answer:

Explanation:

Temperature of gas in absolute scale T = 25 + 273 = 298 .

pressure of gas P = 1.013 x 10⁵ N / m²

density D = 1.799 kg / m³

= 1799 g / m³

From gas formula

PV / T = n R Where P is pressure , V is volume and T is absolute temperature , n is no of moles

P / T = n R / V

P / T = m R /M V where m is mass of gas and M is molecular weight .

m / V = D ( density )

P / T = DR/ M  

PM / DT = R

Putting the values

1.013 x 10⁵ x 44  /  (1799 x 298)

R = 8.314.09 J / K mole

Answer:

35.0 atm + 5.0 atm + 25.0 atm = 65 atm

Explanation:

Partial pressure + Partial pressure + Partial pressure = Total pressure

The concept Dalton's law of partial pressures is used here to determine the total pressure of the gas. The total pressure of the gas is the sum of partial pressures of the gas. Here the total pressure is 65 atm.

The pressure exerted by a mixture of two or more non-reacting gases enclosed in a definite volume is equal to the sum of the partial pressures of the component gases.

The partial pressure of a component gas in a mixture is the pressure that gas would exert if present alone in the vessel at the same temperature as that of the mixture.

Let p₁, p₂, p₃, etc. are the partial pressures. Then the total pressure is given as:

P = p₁ + p₂ + p₃

P = 35.0 + 5.0 + 25.0

P = 65 atm

Thus the total pressure is 65 atm.
