Reduction involves the either the addition of hydrogen and removal of oxygen.
<h3>What is reduction?</h3>
Reduction involves the removal of oxygen.
This implies there is a loss of oxygen in reduction.
This can be represented in the extraction of iron from it ores.
Fe₂O₃ + 3CO → 2Fe + 3CO₂
Reduction is also the addition of hydrogen. This implies it is the gain of hydrogen.
For example
CH₃CHO → CH₃CH₂OH

Answer:
Using the coarse adjustment knob of the microscope in high power may lead to the breaking of the slide if adjusted and raised the slide too much which can damage the sample as well as the high power lens.
In this case, I would recommend using the fine adjustment knob and moving away from the end of the viewing area of the microscope so there would no collision take place. The fine adjustment will help to get a clear image.

Answer:
Alpha particle
Explanation:
An alpha particle is a helium nucleus, 2 protons and 2 neutrons, loss of an alpha particle give a new element with an atomic number 2 less than the original isotope and an atomic mass that is lower by about 4 amu.
Explanation:
Given parameters:
Quantity of heat, H = 257J
Mass of Mercury = 0.45kg
Temperature change = 4.09K
Unknown:
Specific heat capacity = ?
Solution:
The amount of heat absorbed by a body is given as:
H = m c Ф
H is quantity of heat
m is the mass of the body
c is the specific heat
Ф is the temperature change
The unknown is C and we solve for it;
257 = 0.45 x C x 4.09
C = 139.67J/kgK
