The specific heat capacity of a pure substance can be found by dividing the heat needed to change the temperature of a sample of

the substance by the mass of the sample and by the change in temperature. The heat capacity of a certain substance has been measured to be 2.76J·g°C. Suppose 466.g of the substance are heated until the temperature of the sample has changed by 39.4°C. Write an equation that will let you calculate the heat that was needed for this temperature change. Your equation should contain only symbols.

Answer:

See below

Explanation:

ΔQ = m c T        ΔQ = heat required(J)    m = mass (g)    T = C° temp change

                             c = heat capacity in J/g-C

In the following reaction, which component acts as an oxidizing agent? 10 I− (aq) + 2 MnO4− (aq) + 16 H+ (aq) → 5 I2 (s) + 2 Mn2
antiseptic1488 [7]

Answer:

The oxidizing agent is the MnO₄⁻

Explanation:

This is the redox reaction:

10 I⁻ (aq) + 2 MnO₄⁻ (aq) + 16 H⁺ (aq) → 5 I₂ (s) + 2 Mn²⁺ (aq) + 8 H2O (l)

Let's determine the oxidation and the reduction.

I⁻ acts with -1 in oxidation state and changes to 0, at I₂.

All elements in ground state has 0 as oxidation state.

As the oxidation state has increased, this is the oxidation, so the iodide is the reducing agent.

In the permanganate (MnO₄⁻), Mn acts with +7 in oxidation state and decreased to Mn²⁺. As the oxidation state is lower, we talk about the reduction. Therefore, the permanganate is the oxidizing agent because it oxidizes iodide to iodine
