Explanation:
Answer:
Answer:K subscript e q equals StartFraction StartBracket upper C upper O subscript 2 EndBracket StartBracket upper C a upper O EndBracket over StartBracket upper C a upper C upper O subscript 3 EndBracket EndFraction
Explanation: the answer has it's root in Law of mass action which states that; the rate of a chemical reaction is directly proportional to the product of the concentrations of the reactants raised to their respective stoichiometric coefficients.
Answer:
When you heat an atom, some of its electrons are "excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy. ... The different mix of energy differences for each atom produces different colours. Each metal gives a characteristic flame emission spectrum.
Explanation:
<span>The answer is lactic acid/lactate. This is caused by
anaerobic respiration in muscles especially during strenuous physical activity due to low oxygen supply to muscles in respect
to the demand. When there is sufficient oxygen in the muscles, pyruvate is broken down
aerobically in the Kreb’s cycle. However,
it is converted to lactate in the anaerobic
pathway. Lactic-acidosis occurs when
lactic acid accumulates in tissues and slows down metabolic pathways</span>
Here are some trends you should know.
Electronegativity increases as you go right and up along the periodic table.
So, (1) is wrong
Atomic mass increases as you go right and down along the periodic table.
So, (2) is wrong
Proton number or atomic number increases as you go right and down in the table.
So, (3) is correct
Metallic character increases as you go left and down along the periodic table.
So, (4) is wrong
