Answer:
1) combustion
2) double replacement
3) combination
4) combustion
Explanation:
The combustion of a compound refers to the reaction of that compound with oxygen to produce heat and light. In reactions (1) and (4) above, ethanol and methane reacted with oxygen to yield carbon dioxde and water. This is a combustion reaction.
Reaction(2) is a double replacement reaction because the both cations exchange their anion partners in the product.
Reaction (3) is a combination reaction. It involves the joining of two elements to form a new compound.
Answer:
C. Lose three electrons to have a full outer shell
Explanation:
Al is in Group 13 of the Periodic Table, so it has three valence electrons.
It must either lose three electrons or gain five to achieve a stable octet.
It is easier to lose three electrons than it is to gain five, so Al loses three electrons.
D. is wrong, for the same reason.
A. is wrong. If Al lost three electrons, it would be breaking into a stable inner shell.
C. is wrong. Al is a metal, so it will lose electrons in a reaction.
Oh my i really hope no one from my school sees my comments
Answer : The molarity of an acetic acid solution is, 0.0338 M
Explanation :
Formula used :
where,
are the molarity and volume of acetic acid.
are the molarity and volume of NaOH.
We are given:
Putting values in above equation, we get:
Hence, the molarity of an acetic acid solution is, 0.0338 M
Answer:
The correct answer is D.
Explanation:
Amino acids can be classified <u>depending on the side chain structure</u> in
- acidic
- basic
- neutral
- aliphatic
- aromatic
- sulfur containing amino acids.
Aspargine is a <em>neutral amino acid</em> that has a key role in <u>glycoproteins biosynthesis.</u> Aspargine helps the body to resist fatigue and contributes to a smooth functioning of the liver.
