Answer:
Answer 1) Decomposing (Electrolysis) Answer 2) Solar energy
Explanation:
Answer 1) Decomposing (Electrolysis)
Explanation :
Hydrogen can be created by decomposing water. Electrolysis which is a method of passing electricity from the water and obtaining the products as hydrogen and oxygen is done by decomposition of water. The water molecule is broken down into its constituents.
Answer 2) Solar energy
Explanation :
If the activation energy is reduced, hydrogen can be produced with a renewable energy source. This renewable energy source is Solar energy.
Solar energy from the sun can be used to lower the energy of activation during the decomposition of water. Solar energy is a renewable energy source as it comes from the sun and is replenish-able unlike fuels which cannot be replenished. The solar energy can be collected and utilized for production of hydrogen.

The nuclear equation shows the transmutation of a form of radon into polonium and an alpha particle
Answer:
Explanation:
The equation is balanced because the mass and charge are equal on both sides of the reaction equation.
In a nuclear reaction, one nucleus is transformed into another. In this case of the equation shown, the radon nucleus is being transformed into a polonium nucleus with the emission of an alpha particle.
The equation is balanced because a total mass of 219 is found on both sides of the reaction equation and a total charge of 86. Recall that an alpha particle is the same as a helium nucleus with a mass of four units and a charge of two units.

Explanation:
A certain market has both an express checkout line and a super-express checkout line. let x1 denote the number of customers in line at the express checkout at a particular time of day, and let x2 denote the number of customers in line at the superexpress checkout at the same time. suppose the joint pmf of x1 and x2 is as given in the accompanying table.
The problem here is a Joint Probability Distribution exercise. See the answers and explanation below.
What is Joint Probability Distribution?Joint Probability Distribution can be simply described as the likelihood of two events (variables) occurring at the same time.
These two events are commonly referred to as event A and event B, and their formal names are: p (A and B).
What is the solution to the questions?A - The likelihood that each line has exactly one customer: The probability relates to the associated row and column.
X₁ = 1 and X₂ = 1
P (X₁ = 1, X₂ =1) = 0.15
B - The sum of the diagonal elements of the joint pmf indicates the likelihood that the amount of clients in both lines is the same:
P(X₁ = X₂) =) p(0,0) + p (1,1) + p(2, 2) + p(3,3
= 0.08 + 0.15 + 0.10 + 0.07
= 0.4
Hence,
[tex]P(X_{1} = X_{2}) = 0.40[/tex]
C - Let A represent the situation in which there are at least two more clients than the other line: The following are examples of variable combinations:
X₂ =0 ; X₁ = 2,3, 4
X₂ =1 ; X₁ = 3, 4
X₂ =2 ; X₁ = 0, 4
X₂ =3 ; X₁ = 0, 1
The probability is thus computed as follows:
P (A) = p(1, 3) + p (2,2) + p(2, 3) + p(3,1) + p(3,2) + p(3,3) + p(4,0) + p(4,1) + p(4,2) + p(4,3)
= 0.04 + 0.10 +0.06 + 0.03 + 0.04+ 0.07 + 0.00 + 0.01 + 0.05 + 0.06
= 0.46
Hence [tex]P (A) = 0.46[/tex]

A box shaped like a rectangular prism has a volume of 280 in^3
Based on the calculations, the width and height of this rectangular prism are 7 inches and 10 inches respectively.
How to calculate the volume of a rectangular prism?Mathematically, the volume of a rectangular prism can be calculated by using this formula:
V = L × W × H
Where:
L is the length.H is the height.W is the width.Given the following data:
Length = 4 in.
Width = (n + 2) in.
Height = (n + 5) in.
Substituting the given parameters into the formula, we have;
280 = 4 × (n + 2) × (n + 5)
280 = 4 × (n² + 7n + 10)
60 = n² + 7n + 10
n² + 7n - 60 = 0
(n - 5)(n + 12) = 0
Therefore, n = 5 or -12.
For the width, we have:
Width = n + 2
Width = 5 + 2
Width = 7 in.
For the height, we have:
Height = n + 5
Height = 5 + 5
Height = 10 in.

What does balancing chemical equations mean?Reaction balancing is a method used in several areas of Chemistry to determine the amount of matter of each of the substances participating in the reaction, as well as to establish the existing proportions between the components.
Then the equation before performing the balancing is given by:
[tex]NaHCO_3+H_3C_6H_5O_7 \rightarrow Na_3C_6H_5O_7+H_2O+3CO_2[/tex]
For this equation to become balanced it will be necessary that:
On the right side of the equation we have more Na and H so it will be necessary to multiply by 3So the balanced equation will be:

The trigonometric expression is given below.
⇒ cos (11π/12)
We know that 11π/12 is equal to 165 degrees. Then we have
cos 165° = cos (45° + 120°)
We know that
cos (A + B) = cos A cos B - sin A sin B
Then we have
cos (45° + 120°) = cos 45° cos 120° - sin 45° sin 120°
cos (45° + 120°) = 1/√2 x (- 1/2) - 1/√2 x √3/2
cos (45° + 120°) = - (1 + √3)/(2√2)
