Object A specific heat is 2.45 J/g C and object B specific heat is 0.82 J/g C. Which object will heat up more if they have the s
Artist 52 [7]

Answer: Object B will heat up more.

Explanation:

The formula for specific heat is as follows.

                  Q = m C \Delta T

Where,

                      Q = heat provided

                      m = mass

                      C = specific heat

            \Delta T = change in temperature

Now, both the objects have same mass and equal amount of heat is applied.

According to the formula, the equation will be as follows.

                      Q_{1} = Q_{2}

                  m C_{1}\Delta T = m C_{2}\Delta T_{2}

Cancel m from both sides, as mass is same. Therefore,

            C_{1} (T_{f} - T_{i})_A = C_{2}(T_{f} - T_{i})_B

Cancel out the initial temperature and put the values of specific heat, then the equation will be as follows.

             2.45 (T_{f})_A = 0.82(T_{f})_B

Therefore, from the above equation it can be concluded that the object with low specific heat will heat up more as its specific heat will be inversely proportional to its final temperature.

Hence, object B will heat up more.

Write sulfur dioxide reactions
scZoUnD [109]

Answer:

Sulfur dioxide is a covalent bond because  we have two non-metals (Sulfur and Oxygen).

S + O_{2} \to SO_{2} (<em>Sulfur dioxide formula)</em>

It's called Sulfur dioxide but it can be called Sulfurous anhydride and Sulfur (lV) oxide.

Sulfur dioxide can have different reactions:

  • In the presence of oxygen oxidation of sulfur dioxide to sulfur trioxide occurs and the formula is:

SO_{2}+\frac{1}{2} O_{2}= SO3

The equal is because  it's a reversible equation. This reaction is spontaneous.

  • The sulfur trioxide reacting with water produces sulfuric acid. The formula is:

3 SO_{2} + O_{3} \to 3 SO_{3}\\SO_{3} + H_{2}O \to H_{2}SO_{4}

  • Also the sulfur dioxide reacting with  sodium hydroxide produces sodium sulfite and the formula is:

SO_{2} + 2 NaOH \to Na_{2}SO_{3} + H_{2}O

  • And finally we have the reduction of sulfur dioxide (it can be in presence of  hydrogen sulfide) getting elemental sulfur and water. The formula is:

SO_{2} + 2 H_{2}S \to 3 S + 2 H_{2}O
