Answer: The three end products of the oxidation-reduction reactions involved in metabolism are WATER, CARBON DIOXIDE and ATP.
Metabolism refers to the sum of all chemical reactions occurring in the body. It includes both catabolism and anabolism. Every metabolic reaction is characterized by oxidation-reduction reactions. The metabolic pathways include respiration, photosynthesis, etc. In all these reactions water is produced. In respiration CO2 is also a product. In general. in every metabolic reaction either an organic molecule is broken or synthesized producing CO2, water and energy.
so:
so:
it means that
in
of acid there is
moles of acid
so:
it means that:
in
of water there is
moles of water
therefore:
So your answers are:
and the mole fraction is:
Answer:
Principle stating that specific groups of organisms have followed, or succeeded one another in a definite sequence through Earth history
Explanation:
Principle stating that specific groups of organisms have followed, or succeeded one another in a definite sequence through Earth history describe Faunal succession because it is a principle that indicate that fossil plants and animals succeed each other in a sequential manner even if they occur in different places. Successive strata and faunas are linked together to form composite section in the Earth's history.
Answer:
(a) 4
(b) 7
(c) 8
(d) 8
(e) 4
Explanation:
In order to draw the Lewis structure, we need to take into account the octet rule: atoms will share electrons to have 8 electrons in their valence shell.
<em>(a) How many valence electrons does Si have initially? </em>
Si has 4 valence electrons. It has to share 4 pairs of electrons to reach the octet.
<em>(b) How many valence electrons does each Cl have initially? </em>
Cl has 7 valence electrons. Each Cl has to share 1 pair of electrons to reach the octet.
<em>(c) How many valence electrons surround the Si in the SiCl₄ molecule? </em>
Si is surrounded by 8 electrons in SiCl₄.
<em>(d) How many valence electrons surround each Cl in the SiCl₄ molecule? </em>
Each Cl is surrounded by 8 electrons in SiCl₄.
<em>(e) How many bonding pairs of electrons are in the SiCl₄ molecule?</em>
There are 4 bonding pairs between Si and Cl.
Answer:
3,4–diethyloctane
Explanation:
To name the compound, we must do the following:
1. Locate the longest continuous carbon chain. This gives the parent name of the compound. In this case, the longest chain is carbon 8 i.e octane.
2. Identify the substituent attached to the compound. In this case, the substituent group attached is ethyl i.e CH2CH3.
Note: there are two ethyl group attached to the compound.
3. Locate the position of the substituent group attached, giving them the lowest possible count. In this, the ethyl group are at carbon 3 and 4.
4. Combine the above to get the name of the compound. Therefore, the name of the compound is:
3,4–diethyloctane.
