Answer: Option (2) is the correct answer.
Explanation:
An alkene is a molecule that contains a hydrocarbon chain with atleast one double bond.
For example, is a 1-butene molecule and it contains one double bond that consists of four shared electrons.
On the other hand, a molecule of hydrocabon that contains a triple bond is known as an alkyne. Whereas a hydrocarbon that contains only single bonds is known as an alkane.
Thus, we can conclude that the multiple covalent bond in a molecule of 1-butene is a double covalent bond that has 4 shared electrons.
The question given above is not complete, the options attached to the question is given below:
A). Putting them in a deep pool of water
B). Burying them in a deep underground storage facility
C). Sending them on the shuttle to be suspended in space
D). Putting them in concrete/lead casks and sitting at thereactor site
ANSWER
The correct option is C.
There are many ways of storing spent nuclear fuel rods, these include: immersing them in deep pool of water, storing them in lead casks and burying them in deep underground storage. These forms of storage are utilized in order to protect people and the environment from the harmful radiations that radiate from these fuel rods. Spent fuel rods must never be exposed, therefore it is not possible to suspend them in space.
Answer:
c
Explanation:
charged ion
(2) gains three electrons and becomes a negatively
charged ion
(3) loses one electron and becomes a positively
charged ion
(4) loses three electrons and becomes a positively
charged ion
Answer:
loses one electron
Explanation:
The amount of hydrogen produced does not change if the volume of water was decreased to 440mL 400g.
The mole is an amount unit similar to familiar units like pair, dozen, gross, etc. It provides a specific measure of the number of atoms or molecules in a bulk sample of matter.
A mole is defined as the amount of substance containing the same number of atoms, molecules, ions, etc. as the number of atoms in a sample of pure 12C weighing exactly 12 g.
The reaction will be;
Ca(s) + 2 H₂O(l) → Ca(OH)₂(aq) + H₂ (g)
Since water is in excess, because 0.1 moles of calcium requires only 0.2 moles of water which is 3.6 g, therefore changing the mass of water used will not affect the amount of hydrogen gas produced since the amount of hydrogen gas produced depends on the amount of calcium used.
Therefore, The amount of hydrogen produced does not change if the volume of water was decreased to 440mL 400g.

Answer:
The volume of hydrogen produced would be the same.
Answer:
They are Red.
Answer:
The correct answer is meiosis takes place, making the sperm cell haploid.
Explanation:
From secondary spermatocytes, the formation of haploid male gamete, that is, spermatid takes place. Its formation takes place by the procedure of meiosis, and therefore, it comprises half of the genetic substance as found in in the primary spermatocyte.
In the beginning, spermatid is a round, immotile cell that distinguishes and turns motile and unique by the procedure is known as spermiogenesis.
Answer:
The answer to your question is: letter A
Explanation:
A. Gas particles are in constant motion. This statement is true because this theory says that Gases are composed of a large number of particles that behave like hard, spherical objects in a state of constant, random motion.
B. Gas particles attract each other. This statement is false because this theory says that there is no force of attraction between gas particles or between the particles and the walls of the container.
C. Gas particles lose their energy during collisions. This statement is false, this theory says that none of the energy of a gas particle is lost when it collides with another particle or with the walls of the container.
D. Gas particles stick to the walls of their container. This statement is false, the theory says that there is no force of attraction between gas particles or between the particles and the walls of the container.
