Is the rate of decay fastest at the beginning, middle, or end of the process?
Answer:
The beginning
Explanation:
In a nuclear reaction, the rate of decay is fastest at the beginning of the process.
What are nuclear reactions?There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.
In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.
In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

Answer:
Oil- nonpolar
Sugar- polar
Salt- Polar
Dish soap- It is both polar and nonpolar
Explanation:
a) so they will remain separate from molecules of a polar solvent such as water
b) Sugars are polar due to their -OH groups, and dissolve readily in water by forming many hydrogen bonds.
c)At the molecular level, salt dissolves in water due to electrical charges and due to the fact that both water and salt.
d) Soap molecules have both properties of non-polar and polar at opposite ends of the molecule.

Magnesium (24.30g) reacts with hydrogen chloride (xg) to produce hydrogen gas(2.04g) and magnesium chloride (96.90g). How much hydrogen chloride was used in the reaction
We have that for the Question,it can be said that How much hydrogen chloride was used in the reaction is
x=74.42From the question we are told
Magnesium (24.30g) reacts with hydrogen chloride (xg) to produce hydrogen gas(2.04g) and magnesium chloride (96.90g).
How much hydrogen chloride was used in the reactionHow much hydrogen chloride was used in the reactionGenerally the equation for the Reaction is is mathematically given as
Mg+2HCl-----MgCl2+H2
Grams of MgCl2=[tex]\frac{96.9*24.30}{2.04}\\[/tex]

ñ How many total electrons does 0-2 (an oxide ion) have?
Explanation:
1one electron and -1 for anions
2 O2- indicates an ion of oxygen having two extra electrons. I.e., since an oxygen atom normally has 8 protons and 8 electrons, this ion has 10 electrons (-10 charge) and 8 protons (+8 charge) giving it a charge of -2 (-10 + 8 = -2).

the diagram below represents a portion of a cell membrane. The arrow indicates that the cell membrane is carrying out the process of...
Answer:
I'm feeling nice today so heres the answer
Explanation:
In the portion of the cell membrane shown in the diagram, the arrow indicates the process of active transport.
Explanation:
Active transport is one of the mechanisms of transmembrane transport, which involves the use of energy. The diagram (see image) shows the hydrogen (H⁺) output from the cytoplasm to the extracellular space, through an H⁺ pump —consuming ATP— which represents an active transport process.
The hydrophobic nature of the cell membrane prevents the free passage of hydrosoluble elements or ions, as H⁺, so they require the use of active transport to pass through it.
The other options presented are not correct, because
Respiration is a process that occurs in the mitochondria.
Diffusion is a passive transport process that does not require energy.
Cellular recognition depends on membrane proteins that act as specific receptors.
Answer:the answer is active transport

what evidence lead rutherford to propose that the atom had a nucleus?
Answer:
When he shot radiation through gold foil, some of the radiation shot back, some went directly through, and some slight angled off.
Explanation:
He knew that the radiation that had gone all the way through had not hit anything.
He knew that the radiation that came directly back must have hit a big nucleus.
He knew that the radiation that angled slightly off must have hit a smaller, orbiting particle (electrons).
