Answer:
Exothermic reaction
Explanation:
The freezing of n-octane is an exothermic reaction.
An exothermic reaction is a type of reaction in which energy usually in the form of heat is released to the environment. In an exothermic reaction, the reactants are at a higher energy level compared to the product. Hence heat energy is usually released.
Now, freezing is a change in state from the liquid state to the solid state , for example, the turning of water to ice block.
In freezing, energy is released and hence, thus it is an exothermic reaction
Answer:
three orbits
Explanation:
electronic configuration is 2,8,1
so there are 3 orbits
Answer:
Granite
Explanation:
The specific heat capacity of a substance, which is denoted by "c", is the amount of heat required to raise the temperature of a particular mass of that substance by 1°C. It is calculated as follows:
c = Q ÷ m∆T
Where;
c = specific heat capacity
Q = amount of heat (J)
m = mass of substance
∆T = change in temperature.
According to this equation and explanation above, a low specific heat capacity means that the rate at which the temperature is raised is slow and vice versa. Hence, from this question, GRANITE with specific capacity of 0.790 J/gK will raise temperature the slowest.
