Explanation:

The first given equation in words is as follows.

solid sodium + chlorine gas \rightarrow solid sodium chloride

The chemical equation for this reaction will be written as follows.

        Na(s) + Cl(g) \rightarrow NaCl (s)

The second given equation in words is as follows.

solid sodium + liquid water \rightarrow aqueous sodium hydroxide + hydrogen gas

The chemical equation for this reaction will be written as follows.

    Na(s) + H_{2}O(l) \rightarrow NaOH(aq) + H_{2}

The third given equation is as follows.

    2H_{2}(g) + O_{2}(g) \rightarrow 2H_{2}O(g)

This equation can be written in words as follows.

hydrogen gas + oxygen gas \rightarrow water gas

The fourth given equation is as follows.

     2H_{2}O_{2}(aq) \rightarrow O_{2}(g) + 2H_{2}O(l)

This equation can be written in words as follows.

aqueous hydrogen peroxide \rightarrow oxygen gas + liquid water

Thus, match the given data as follows.

  • solid sodium + chlorine gas \rightarrow solid sodium chloride - (2).  2Na(s) + Cl_{2}(g) \rightarrow 2NaCl (s)
  • solid sodium + liquid water \rightarrow aqueous sodium hydroxide + hydrogen gas - (4).  2Na(s) + 2H_{2}O(l) \rightarrow 2NaOH(aq) + H_{2}
  • 2H_{2}(g) + O_{2}(g) \rightarrow 2H_{2}O(g) - (3). hydrogen gas + oxygen gas \rightarrow water gas.
  • 2H_{2}O_{2}(aq) \rightarrow O_{2}(g) + 2H_{2}O(l) - (1). aqueous hydrogen peroxide \rightarrow oxygen gas + liquid water

135 Joules of heat are required to increase the temperature of 10.0 grams of an unknown metal from 25.0∘C to 40.0∘C:
Sever21 [200]

Answer:

270 Joules

Explanation:

The specific heat capacity equation will be used for this question i.e.

Q = m. c. ΔT

Where; Q = Amount of heat

m = mass of substance

C = specific heat capacity of

substance

ΔT = change in temperature

(Final temp - initial temp)

However, for this unknown metal, we need to find the specific heat first by saying; C = Q / mΔT

Q= 135J, C=?, m= 10g, ΔT = (40-25 = 15°C)

C = 135 / 15 × 10

C = 135/150

C = 0.9 J/g°C

If the specific heat capacity of the unknown metal is 0.9 J/g°C, then at a mass of 20.0g, and a ΔT of 15°C, the amount of heat needed is:

Q = m. c. ΔT

Q = 20 × 0.9 × (40-25)

Q = 18 × 15

Q = 270J

270 Joules of heat is needed to increase the temperature of 20g of the metal from 25 - 40°C

The solubility of nitrogen gas at 25 degrees C and 1 atm is 6.8 x 10^(-4) mol/L. If the partial pressure of nitrogen gas in air
Zolol [24]

Answer:

5.2 x 10⁻⁴ M.

Explanation:

  • The relationship between gas pressure and the  concentration of dissolved gas is given by  Henry’s law:

<em>P = kC</em>

where P is the partial pressure of the gaseous  solute above the solution.

k is a constant (Henry’s constant).

C is the concentration of the dissolved gas.

  • At two different pressures, there is two different concentrations of dissolved gases and is expressed in a relation as:

<em>P₁C₂ = P₂C₁,</em>

P₁ = 1.0 atm, C₁ = 6.8 x 10⁻⁴ mol/L.

P₂ = 0.76 atm, C₂ = ??? mol/L.

<em>∴ C₂ = (P₂C₁)/P₁ =</em> (0.76 atm)(6.8 x 10⁻⁴ mol/L)/(1.0 atm) = <em>5.168 x 10⁻⁴ mol/L ≅ 5.2 x 10⁻⁴ M.</em>

To what volume should 25ml of 15m nitric acid be diluted to prepare a 3m solution
Maurinko [17]

We can use the dilution formula to find the volume of the diluted solution to be prepared

c1v1 = c2v2

Where c1 is concentration and v1 is volume of the concentrated solution

And c2 is concentration and v2 is volume of the diluted solution to be prepared

Substituting the values in the equation

15 M x 25 mL = 3 M x v2

v2 = 125 mL

The 25 mL concentrated solution should be diluted with distilled water upto 125 mL to make a 3 M solution
