The temperature change on a 150g sample of mercury with specific heat of 0.0330 Cag°C, If 480 cal of heat is added to it is 96.9°C.
<h3>How to calculate temperature change?</h3>
The temperature change of a substance can be calculated using the following formula:
Q = m × c × ∆T
Where;
- Q = quantity of heat absorbed or released
- m = mass of substance
- c = specific heat capacity
- ∆T = change in temperature
480 = 150 × 0.033 × ∆T
480 = 4.95∆T
∆T = 96.9°C.
Therefore, the temperature change on a 150g sample of mercury with specific heat of 0.0330 Cag°C, If 480 cal of heat is added to it is 96.9°C.

<u>Answer:</u> The half life of the reaction is 593.8 seconds
<u>Explanation:</u>
We are given:
Rate constant =
The formula for determining the unit of 'k' is:
where, n = order of reaction
The unit of concentration is, M or mole/L
The unit of time is, second or 's'
Evaluating the value of 'n' from above equation:
The reaction is zero order reaction.
The equation used to calculate half life for zero order kinetics:
where,
k = Rate constant =
= initial concentration = 1.90 mol/L
Putting values in above equation, we get:
Hence, the half life of the reaction is 593.8 seconds
Answer:
Differentiation
Explanation:
Planet differentiation can be defined as the process of chemically separating the various constituents of a planetary body by outgassing of volatilities and partial melting into different distinct or distinguished compositional layers.
Differentiation explains the arrangement of the inner planets' composition into different chemical layers. During the differentiation of the inner planets composition, less-dense liquids erupts from the melt in the direction of the planets' surface and then crystallizes to form a crust, which typically result in the depletion of elements such as Aluminum and Silicon from the mantle.
The various chemical layers of the planet Earth are the mantle, crust, and core (inner and outer).
