Answer:

a) acidic; [H+] = 10^-2.5 = 3 x 10^-3

b) basic; [H+] = 10^-11.7 = 2 x 10^-12

c) slightly acidic (almost neutral); [H+] = 10^-6.8 = 1.6 x 10^-7

d) acidic; [H+] = 10^-3.31 = 4.9 x 10^-4

Explanation:

pH < 7 is acidic; pH > 7 is basic; pH = 7 is neutral

[H+] = 10^-pH

Mercury has a specific gravity of 13.6. how many milliliters of mercury have a mass of 0.35 kg
SashulF [63]

The formula for specific gravity is:

Specific gravity = \frac{\rho _{substance}}{\rho _{water}}

where \rho _{substance} is the density of the substance and \rho _{water} is the density of water.

The density of water, \rho _{water} = 1 g/mL

Substituting the values in above formula we get,

13.6 = \frac{\rho _{substance}}{1}

\rho _{substance} = 13.6 g/mL

The formula of density is:

density = \frac{mass}{volume}

The density of mercury is 13.6 g/mL

The mass of mercury is 0.35 kg = 0.35 kg \times 1000 \frac{g}{kg} = 350 g

Substituting the values in density formula:

13.6 g/mL = \frac{350 g}{volume}

volume = \frac{350 g}{13.6 g/mL} = 25.73 mL

1.For the first ten reactions, write a balanced reaction for each tube in which a reaction occurred. If there was no reaction, w
slamgirl [31]

The equations of reaction occurring in the tubes are as follows:

  • 2 MnO₄⁻ + 6 Br⁻ + 8 H⁺ → 2 MnO₂ + 3 Br₂ + 4 H₂O
  • 2 MnO₄⁻ + 6 I⁻ + 8 H⁺ → 2 MnO₂ + 3 I₂ + 4 H₂O
  • No reaction
  • 2 Fe³⁺ + 2 I⁻ → 2 Fe²⁺ + I₂

<h3>What are the reactions occurring in the tubes?</h3>

The reactions occurring in the tubes are redox reactions.

Based on the table the equations of reaction are as follows:

  • 2 MnO₄⁻ + 6 Br⁻ + 8 H⁺ → 2 MnO₂ + 3 Br₂ + 4 H₂O
  • 2 MnO₄⁻ + 6 I⁻ + 8 H⁺ → 2 MnO₂ + 3 I₂ + 4 H₂O
  • No reaction
  • 2 Fe³⁺ + 2 I⁻ → 2 Fe²⁺ + I₂

In conclusion, redox reaction are reactions in which electrons are transferred.
