1) A 45.7 g sample of glass was brought to thermal equilibrium with boiling water and then transferred to 250.0 g of water that was at 22.5 °C. This combination reached thermal equilibrium at 24.2 °C. What is the specific heat capacity of glass?

2) What mass of silver at 100.0 °C, when added to 150.0 g of water at 21.0 °C, would raise the water’s temperature to 24.0 °C ?

3) The molar heat of fusion of H2O is 6.1 kJ/mole. What amount of energy would be needed to melt 376 g of ice at 0.0 °C?

Answer:

Ar(Mg)=24g

Ar(Cl)=35,5 and Cl2=35,5×2=71g

m=24g+71g=95g

Answer:

K = 0.5

Explanation:

Based on the reaction:

PCl₃ + Cl₂ ⇄ PCl₅

The equilibrium constant, K, is defined as:

K = P PCl₅ / P PCl₃ * P Cl₂

Where P represent the pressure at the equilibrium for each one of the gases involved in the equilibrium.

As:

P PCl₅ = 1.0atm

P PCl₃ = 1.0atm

P Cl₂ = 2.0atm

K = 1.0atm / 1.0atm * 2.0atm

Answer: the answer is D the last one.

Answer:

[tex]206.6\ \text{kPa}[/tex]

Explanation:

[tex]P_1[/tex] = Initial pressure = 200 kPa

[tex]P_2[/tex] = Final pressure

[tex]T_1[/tex] = Initial temperature = [tex]30^{\circ}\text{C}[/tex]

[tex]T_2[/tex] = Final temperature = [tex]40^{\circ}\text{C}[/tex]

We have the relation

[tex]\dfrac{P_2}{P_1}=\dfrac{T_2}{T_1}\\\Rightarrow P_2=\dfrac{T_2}{T_1}P_1\\\Rightarrow P_2=\dfrac{40+273.15}{30+273.15}\times 200\\\Rightarrow P_2=206.6\ \text{kPa}[/tex]

The pressure that would be exerted after the temperature change is [tex]206.6\ \text{kPa}[/tex].

Explanation:

Based on the information given, the image represents a negatively charged fluoride atom (Option B)

An atom is composed of a centrally placed nucleus (containing protons and neutrons) and a cloud of electrons revolving round it.

From the question given above, the following data were obtained:

Charge = Proton – Electron

Charge = 9 – 10

Charge = –1

Note

Element with proton number of 9 is fluorine

Thus, we can conclude that the image represents a negatively charged fluoride ion (Option B)

Explanation:

The resulatant volume of gas under given conditions is 9.49 liters.

Ideal gas equation gives idea about the behavior of gases at different conditions and it will be represented as:

PV = nRT, where

P = pressure in atm

V = volume in L

n = moles of gas

R = universal gas constant = 0.082 L.atm/K.mol

T = temperature in K

First we calculate the moles of gas by putting the values according to the first condition in the above equation and we have

n = (0.921)(500) / (0.082)(473) = 11.86 moles

Now we calculate the volume of gas by using the above equation and details of the second condition as:

V = (11.86)(0.082)(293) / (30) = 9.49 L

Hence resultant volume of the gas is 9.49L.

Explanation:

The solute wether electrolyte or a nonelectrolyte, has the greater effect on the boiling point when a given amount of each solute is dissolved in the same mass of water The nonelectrolyte does because it dissociates into ions.

Solute refers to substances or liquid which can readily dissolve in a solvent. It's concentration is lower to that of solvent.

Therefore, The solute wether electrolyte or a nonelectrolyte, has the greater effect on the boiling point when a given amount of each solute is dissolved in the same mass of water The nonelectrolyte does because it dissociates into ions

Answer:

The initial volume in mL is 5959.2 mL

Explanation:

As the number of moles of a gas increases, the volume also increases.  Hence, number of moles and volumes are directly proportional i.e

n ∝ V

Where n is the number of moles and V is the volume

Then, n = cV

c is the proportionality constant

∴n/V = c

Hence n₁/V₁ = n₂/V₂

Where n₁ is the initial number of moles

V₁ is the initial volume

n₂ is the final number of moles

and V₂ is the final volume.

From the question,

n₁ = 0.693 moles

V₁ = ?

n₂ = 0.928 moles

V₂ = 7.98 L

Putting the values into the equation

n₁/V₁ = n₂/V₂

0.693 / V₁ = 0.928 / 7.98

Cross multiply

∴ 0.928V₁ = 0.693 × 7.98  

0.928V₁ = 5.53014

V₁ = 5.53014/0.928

V₁ = 5.9592 L

To convert to mL, multiply by 1000

∴ V₁ = 5.9592 × 1000 mL

V₁ = 5959.2 mL

Hence, the initial volume in mL is 5959.2 mL
