Answer: a. 0.8 tons p. month.
Explanation:
Given: Total nuclear waste = 60,000 metric tons
Time take = 60 years = 12 x 60 months [ 1 year = 12 months]
= 720 months
Total nuclear power plants = 104
Now , Average waste produced by each plant = [tex]\dfrac{\text{Total waste}}{\text{Time x Number of plants}}[/tex]
[tex]=\dfrac{60000}{720\times104}\approx0.8\text{ tons per month.}[/tex]
Hence, 0.8 tons p. month is produced by each plant.
So, option a. is correct.

A. Is a gas
B. Has atomic number 1
C. Has many unique properties
D. Does not exist as a free element in nature
Hydrogen is the chemical element that is placed separately from the other elements because it has atomic number 1.
What is hydrogen?It is the simplest chemical element (consisting of only one proton and one electron) with atomic number 1.
It is the lightest of the elements and the most abundant in the universe and in the earth's crust, in the atmosphere, hydrogen is found as a colorless, odorless and flammable gas, in its molecular form H2.
Therefore, we can conclude that Hydrogen is the chemical element that is placed separately from the other elements because it has atomic number 1.

Compound produced
Solution
In determining the product that may be produced is to use the principle of the law of conservation of mass where the number of atoms/elements in the reaction either before the reaction (reactants) or after the reaction (products) is the same so that a balanced chemical equation is formed.
In the above reaction, there are two elements that play a role in the reaction, namely H and O
So that the resulting product also has these 2 elements, so we can ignore options A and C because there are elements C and Cl, while choice B does not contain the element H
The right choice: D

Group of answer choices
A. Beta
B. Gamma
C. Alpha
D. None of the above
Answer:
C. Alpha
Explanation:
In a nuclear reactor facility, radioactive decay takes place, which is any several processes by which unstable nuclei emit subatomic particles and ionizing radiation and disintegrate into one or more smaller nuclei. A scientist working under this condition is likely to be exposed to alpha particles because it contains a minimal absorption range and they are the least dangerous regarding external exposure.

What is Covalent bond ?Covalent bond, in chemistry, the interatomic linkage that results from the sharing of an electron pair between two atoms.
As in CaO , Ca is considered as Metal which has Electron donor nature hence it will donate electron to Oxygen.
Whereas Oxygen Considered as Non metal as it gains electron. which has electron gainer nature.
Ca donates electron and Oxygen gains electron. Thus, the bond formed between both will be the Ionic bond which is formed by the transfer of Electron.

Mass of Cu : 95.319 g
Further explanationGiven
9.03 x 10²³atoms of Copper
Required
mass of Cu
Solution
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
Mol of Copper :
n = N/No
n = 9.03 x 10²³/6.02.10²³
n = 1.5
Mass of Copper :
= mol x Ar Cu
= 1.5 x 63,546 g/mol
= 95.319 g
9.03 × 10²³ atoms of copper have a mass of 95.3 g.
We want to convert 9.03 × 10²³ atoms of copper to grams. We will need a series of conversion factors.
What is a conversion factor?A conversion factor is an arithmetical multiplier for converting a quantity expressed in one set of units into an equivalent expressed in another.
Step 1: Convert 9.03 × 10²³ atoms to molesThe required conversion factor is Avogadro's number: there are 6.02 × 10²³ atoms in 1 mole of atoms.
9.03 × 10²³ atoms × (1 mol/6.02 × 10²³ atoms) = 1.50 mol
Step 2: Convert 1.50 moles to gramsThe required conversion factor is the molar mass of copper: 63.55 g/mol.
1.50 mol × 63.55 g/mol = 95.3 g
9.03 × 10²³ atoms of copper have a mass of 95.3 g.

24. Two boys were each pushing a box to the right, one boy applied a force of 3N and
the other boy applied a force of 5N. Another boy was pushing the box to the left
with a force of 8N. What was the net force of the box?
Answer:
Explanation:
Two boys were each pushing a box to the right, one boy applied a force of 3N and the other boy applied a force of 5N.
Total force applied to the left = 3 + 5 = 8 N . The forces are added up because they act in the same direction .
Another boy was pushing the box to the left with a force of 8N.
8 N force acts opposite to the total force of 8 N exerted by two earlier boys so
net force = 8N - 8N = 0 .
Net force on the box = 0 .

Explain why beryllium is produced when potassium is heated with beryllium
chloride.
You should refer to reactivity in your answer.
Explanation:
The more reactive element replaces less reactive element during chemical reaction.
Since, potassium is more reactive than beryllium. When potassium reacts with beryllium choride, it replaces beryllium and forms potassium chloride and produces beryllium.
Beryllium is produced due to the fact that the more reactive element in the reaction would have to take over the element that is less reactive.
The chemical reaction of Potassium and Beryllium chloride
In this reaction the element that is more reactive is potassium. When the reaction takes place it would take over and replace beryllium due to this quality.
Hence beryllium chloride would become potassium chloride from the resulting reaction.
