<em>Each element is given its own chemical symbol, like H for hydrogen or O for oxygen. Chemical symbols are usually one or two letters long. Every chemical symbol starts with a capital letter, with the second letter written in lower case. For example, Mg is the correct symbol for magnesium, but mg, mG and MG are wrong...

Answer:
Bicarbonate buffer system
Explanation:
The human body uses a bicarbonate buffer system to maintain blood pH at a reasonable level. Without it, we'd be dead.
Answer: <span>Chlorine is losing electrons and being oxidized.
Justification:
1) Chlorine is losing electrons
As you se the side of the products shwo two electrons, that means that those electons were lost by the reactants. Given that the only reactant is chlorine, it is releasing or losing those electrons.
2) Chlorine is being oxidized.
The substance that loses electrons and, hence, increases its oxidation number, is the substance being oxidized.
In this case Cl (-) in the side of the reactants has oxidation state (1-), while Cl2 in the side of the products has oxidation state 0. This shows that the oxidation state of chlorine increased, meaning that it is being oxidized.

Answer:
a) find attached image 1
b) find attached image 2
Explanation :
The more stable radical is formed by a reaction with smaller bond dissociation energy.
since the bond dissociation for cleavage of the bond to form primary free radical is higher, more energy must be added to form it. This makes primary free radical higher in energy and therefore less stable than secondary free radical.
Answer:
Thallium absorbed 1069.645 J heat to reach to its melting point.
Explanation:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Given data:
Mass of thallium = 32.9 g
specific heat capacity of thallium = 0.128 j/g. °C
Initial temperature = 49 °C
Final temperature = 303 °C
Solution:
Change in temperature = T₂- T₁
ΔT = 303 °C - 49 °C = 254 °C
Formula:
Q = m.c. ΔT
Q = 32.9 g ×0.128 j/g. °C × 254 °C
Q = 1069.645 J
Thallium absorbed 1069.645 J heat to reach to its melting point.
