What is nuclear fusion?Nuclear fusion involves the fusion of 2 smaller nuclei into bigger nuclei.
Nuclear fission and nuclear fusion are nuclear reactions that produce energy in the form of heat. Fission is the process of the division of heavy, unstable nuclei into two nuclei, and in fusion two nuclei combine, resulting in the release of energy.
It occurs naturally in the Sun -The proton-proton fusion is the source of energy from the Sun. The energy from the sun occurs inside the core of the Sun.
It released a large amount of energy - Fission and fusion are two physical processes and produce large amounts of energy from atoms.
It involves the joining of two atomic nuclei - Nuclear fusion happens in the Sun and other stars when two atomic nuclei make one larger one.
Hence, options B, C and D are correct.

13,000J
113,000J
-113,000J
-130J
Answer:
[tex]Q=113,000J[/tex]
Explanation:
Hello there!
In this case, since the vaporization process is carried out in order to turn a liquid into a gas due to the addition of heat, we can use the following heat equation involving the heat of vaporization of water or any other substance:
[tex]Q=m*\Delta _{vap}H[/tex]
Thus, since this heat of vaporization for water is 2259.36 J/g, we plug in this amount to obtain the total energy for this process.
[tex]Q=50*2259.36 J/g\\\\Q=113,000J[/tex]
Which is positive due to the necessity of heat.

If a gas is 0.8L at 900 mm Hg and 400K, what is the new pressure if the volume decreases to 0.5L and 300K?
Answer:
The new pressure of the gas is 1080 mmHg
Explanation:
The general equation provides a way to calculate the relationship between changesnp in volume, temperature and pressure of a given mass of gas.
The general gas equation is given as P1V1/T1 = P2V2/T2
Where P1 is initial pressure of gas
V1 is initial volume of gas
T1 is initial temperature of gas
P2 is final pressure of gas
V2 is final volume of gas
T2 is final temperature of gas
From the given question, P1 = 900 mmHg, V1 = 0.8 L, T1 = 400 K, P2 = ?, V2 = 0.5 L, T2 = 300 K
Making P2 subject of the general gas equations:
P2 = P1V1T2/V2T1
P2 = (900 × 0.8 × 300) / (0.5 × 400)
P2 = 1080 mmHg
Therefore, the new pressure of the gas is 1080 mmHg.

O 2.0
O 6.8
07.0
O 8.7
Please help there are so many different answers which one is right
Answer:
8.7
Explanation:
A weak acid and a strong base will form a more basic salt.
2.0 is more acidic, you'll usually see this from a reaction between a strong acid and a weak base.
6.8 and 7.0 are neutral (or close to neutral) and are formed from reactions between weak acids and weak bases, or strong acids and strong bases.

Calculate the amount of heat needed to melt 78.0g of solid methanol (CH^3OH) and bring it to a temperature of . Round your answer to 3 significant digits. Also, be sure your answer contains a unit symbol.
Answer:
31.0kJ
Explanation:
To a temperature of 19.8°C
To solve this question we must, as first, find the heat necessary to melt the 78.0g of methanol. Then, the heat to increase the temperature from the melting point (-97.53°C) to 19.8°C as follows:
Melting methanol -Molar mass: 32.04g/mol-
78.0g * (1mol / 32.04g) = 2.434 moles
As heat of fusion is 3.215kJ/mol:
2.434 moles * (3.215kJ / mol) = 7.83kJ
Heating methanol:
Q = S*m*ΔT
Where Q is heat in J,
S is specific heat = 2.53J/g°C
m is mass of methanol = 78.0g
ΔT is change in temperature = (19.8°C - (-97.53°C)) = 117.33°C
Replacing:
Q = 2.53J/g°C*78.0g*117.33°C
Q = 23154J
Q = 23.2kJ
Total heat is:
31.0kJ3. How many molecules are in 2.10 moles of H2O?
Answer:
1.264 × 10²⁴ moleculesExplanation:
The number of molecules can be found by using the formula
N = n × L
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 2.10 × 6.02 × 10²³
We have the final answer as
1.264 × 10²⁴ moleculesHope this helps you

What is the role of a consumer in the flow of energy through a food chain?
Answer:
The role of consumers in an ecosystem is to obtain energy by feeding on other organisms and sometimes transfer energy to other consumers. Changes that affect consumers can impact other organisms within the ecosystem.
Explanation:
Hope this helped Mark BRAINLIEST!!!!
Consumers are organisms that obtain energy by eating other organisms. Consumers may consume either producers or other consumers. Consumers include animals.
What is food chain ?A food chain is a network of links in a food web that begins with producer organisms and ends with an apex predator, detritivore, or decomposer species.
A food chain also demonstrates how organisms are related to one another through the food they consume. Each trophic level is represented by a different level of a food chain.
Producers can produce their own food and energy, but consumers are not the same. Consumers are living things that must hunt, gather, and eat their food.
Thus, Consumers must eat in order to gain energy, or they will perish. Omnivores, carnivores, herbivores, and decomposers are the four types of consumers.
