Answer:</h3>
#a. 25.33 kPa
#b. 0.25 atmospheres
<h3>
Explanation:</h3>
- Pressure may be measured using several units which include pascals, atmospheres, mmHg and kilopascals.
- These units of measuring pressure may be converted from one unit to another using a conversion factor.
For example;
1 kPa = 7.5 mmHg
Thus, in our case,
#a. To convert 190 mmHg to kPa
we divide 190 mmHg by 7.5 mmHg
= 190 mmHg ÷ 7.5 mmHg
= 25.33 kPa
Hence, 190 mmHg is equivalent to 25.33 kilopascals
Another conversion factor is;
1 atm = 760 mmHg
Therefore, in our case,
#b. To convert 190 mmHg to atmospheres
we divide 190 mmHg by 760 mmHg
That is; 190 mmHg ÷ 760 mmHg
= 0.25 atm
Thus, 190 mmHg is equivalent to 0.25 atm
Answer:
Synthesis
Explanation:
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
General equation;
A + B → AB
The given reaction is synthesis reaction.
Chemical equation:
2Al + Cl₂ → 2AlCl
it is also redox reaction because oxidation reduction take place.
The oxidation state of aluminium and chlorine is zero on left side while it on right side aluminium become cation with charge of +1 and chlorine become anion with a charge of -1.
Aluminium is reducing agent while chlorine is oxidizing agent.
Oxidizing agents:
Oxidizing agents oxidize the other elements and itself gets reduced.
Reducing agents:
Reducing agents reduced the other element are it self gets oxidized.
