HELP FAST!! Two carbon atoms (Group 14) bond with two hydrogen atoms (Group 1) to form acetylene (C2H2). How would each carbon
atom in acetylene bond? (1 point)
Each carbon atom would share one pair of electrons with hydrogen and three pairs with the other carbon
atom
Each carbon atom would share one pair of electrons with the other carbon atom and three pairs with each
hydrogen atom
Each carbon atom would share one pair of electrons with the other carbon atom and two pairs with each
hydrogen atom
Each carbon atom would share one pair of electrons with hydrogen and one pair with the other carbon
atom
Answer: C
Explanation: Each carbon atom would share one pair of electrons with hydrogen and three pairs with the other carbon atom.
Each carbon atom would share one pair of electrons with hydrogen and three pairs with the other carbon atom Hence option A is correct.
What are electrons?Electrons are defined as a subatomic particle with a negative charge that makes up the nucleus of an atom along with protons and neutrons. Gravitation, electromagnetic interactions, weak interactions, electricity, magnetism, chemistry, and thermal conductivity are just a few of the physical processes that depend on electrons.
An atom of carbon has four electrons. It needs four electrons to become stable because that is its outermost shell. Three pairs of electrons are covalently bound between two carbon atoms to form acetylene, and the final pair is covalently joined to two hydrogen atoms.
Thus, each carbon atom would share one pair of electrons with hydrogen and three pairs with the other carbon atom Hence option A is correct.

Is fire a plasma or a gas?
Answer:
Most flames are made of hot gas, but some burn so hot they become plasma. The nature of a flame depends on what is being burnt. A candle flame will primarily be a mixture of hot gases (air and vaporised paraffin wax). The oxygen in the air reacts with the paraffin to produce heat, light and carbon dioxide.
Answer:
Fire is considered a plasma. Most people get fire confused with gas.

How is the number of electrons in an element determined?
The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.
Answer:
By finding the number of protons
Explanation:
Keep in mind when trying to find the number of electrons of a element, the number of electrons also equals the number of protons. In order to find the number of protons in the element simply find it's atomic number.
Example:
Find the number of electrons in the element iron.
Fe (Iron)
Fe's atomic number is 26
Protons/electrons = 26

Why do atoms want 8 valence electrons?
1) 8 valence electrons are a full shell that makes the atom more stable.
2) 8 valence electrons help atoms dissolve in water.
3) In nature, 8 is the number at which all matter is most happy.
4) 8 valence electrons make the atom better able to react with other elements.
Answer:
1) 8 valence electrons are a full shell that makes the atom more stable.
Explanation:
Due to the octet rule, atoms tend to form compounds in ways that give them eight valence electrons and thus give them the electron configuration of a noble gas, making them stable.
Precautions to be taken when is experimenting the boiling point of liquids
How can you increase the boiling point of water?
A. By increasing the volume of the water
B. By increasing the air pressure above the water
C. By lowering the air temperature above the water
ОО
D. By lowering the pressure of the water
Answer: B
Explanation:
You can increase the pressure above the boiling water.
The boiling point of a liquid varies depending upon the surrounding environmental pressure. A liquid in a partial vacuum has a lower boiling point than when that liquid is at atmospheric pressure. A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure.
choose any bases that will selectively deprotonate the above acid, that is, any bases that will favor the formation of products.
In order to deprotonate an acid, we must remove protons in order to achieve a more stable conjugate base. For this example, we can use the relationship between carboxylic acid and hydroxide.
Deprotonation is the removal of a proton from a specific type of acid in reaction to its coming into contact with a strong base. The compound formed from this reaction is known as the conjugate base of that acid. The opposite process is also possible and is when a proton is added to a special kind of base. This is a process referred to as protonation, which forms the conjugate acid of that base.
For the example we have chosen to give, the conjugate base is the carboxylate salt. This would be the compound formed by the deprotonated carboxylic acid. The base in question was strong enough to deprotonate the acid due to the greater stability offered as a conjugated base.

Bismuth-210 has a half life of 5.0 days if you had a sample of 60.00g of Bismuth-210 how much would be left after 15 days? (Show Your Work)
Answer:
7.5 gm left
Explanation:
Bismuth-210 has a half life of 5 days
15 days is 15/5 = 3 half lives
since half the amount is left in 5 days or 1 half life
(1/2) x (1/2) x (1/2) the staring amount would be left in
3 half lives. so 1/8 is left
(1/8) x 60.0 = 7.5 gm left
