Answer:
Fusion
Explanation:
Fission definition:
In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into two or more smaller, lighter nuclei.
Fusion definition:
Nuclear fusion is the process by which two or more atomic nuclei join together, or “fuse,” to form a single heavier nucleus. During this process, matter is not conserved because some of the mass of the fusing nuclei is converted to energy, which is released.
Both together: (vs.)
Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.

How does oxygen obey the octet rule
Answer:
oxygen obey the octet rule when reacting to form compounds by adding 2 electrons.
Explanation:
Answer:
See below.
Explanation:
An oxygen atom, in free state has 8 electrons, 2 in the first shell, and 6 in the second. It can only achieve stability if the valency of the valence shell is 0. In order for this, it combines with another atom with the same valency, such as magnesium or another oxygen atom to obey the octet rule. Hope it helps.

Which gas is most likely to act as an ideal gas at STP?
A. hydrogen
B. Oxygen
C. methane
D. carbon dioxide
Oxygen gas is most likely to act as an ideal gas at STP. Therefore, option B is correct.
What is an ideal gas?An ideal gas is a hypothetical gas composed of randomly moving point particles without interparticle interactions. The ideal gas is useful because it follows the ideal gas law.
Under various conditions of temperature or pressure, many real gases behave like an ideal gas where the gas molecules as the ideal particles. Many gases such as nitrogen gas, oxygen gas, hydrogen gas, noble gases, some heavier gases such as carbon dioxide, and mixtures such as air, can be treated as ideal gases.
A gas behaves more likely as an ideal gas at higher temperature and lower pressure, as the potential energy because intermolecular forces become less and the size becomes less significant compared to the vacant space between them.
One mole of an ideal gas has a volume of 22.7 liters at standard temperature and pressure. At high pressures, the volume of a real gas is generally larger than that of an ideal gas.

If a 78.51 g stone is added to a graduated cylinder, the water level rises from 20 mL to 45 mL. What is the density of the stone?
Answer:
The answer is 3.14 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume}\\[/tex]
From the question
mass = 78.51 g
volume = final volume of water - initial volume of water
volume = 45 - 20 = 25 mL
So we have
[tex]density = \frac{78.51}{25} \\ = 3.1404[/tex]
We have the final answer as
3.14 g/mLHope this helps you
Which object will have particles with the highest average kinetic energy?(1 point)
1. an iceberg at 0°C
2. water at 37°C in a glass
3. a drop of water at 90°C
4. water at 40°C in a swimming pool
Answer:
The answer will "a drop of water at 90°C"
Explanation:
Kinetic energy is a measurement of how fast or slow particles move. And temperature = Kinetic energy.
What does this mean?
Well, this means that the higher the temperature, the higher the kinetic energy. The mass of the water doesn't affect the kinetic energy, since the kinetic energy is the measurement of only the movement of the particles. So, we can ignore the masses. Therefore, that means the answer will be the drop of water, as it has the highest temperature.
Average kinetic energy is the average sum of all kinetic energy of all the molecules of gases. A drop of water at 90°C has the greatest average kinetic energy. Therefore option 3 is the correct option.
What is kinetic energy?
It is a energy which is possess by a moving object. It is very difficult to find the correct value of kinetic energy so we find average kinetic energy. Which is very easy to calculate as compared to calculating kinetic energy . Average kinetic energy is directly proportional to temperature. It is not dependent on the type of gases or mass of gases
Mathematically,
K.E=2/3KT
Where,
K= Boltzmann constant
T is the temperature
Water at higher temperature will have higher average kinetic energy. Among given options, a drop of water at 90°C is at higher temperature. Thus a drop of water at 90°C has the highest average kinetic energy among all. Therefore option 3 is the correct option.

Temperature is a measure of the amount of heat energy in an object. True False
Answer:
True
Explanation:

Copper reacts with sulfur to form copper (i) sulfide, according to the balanced equation below. 2cu s → cu2s given that there are 40.2 g cu and 14.1 g s, complete the steps below to determine the limiting and excess reactants in the last question. how many moles are in 40.2 g cu? mol cu how many moles are in 14.1 g s? mol s
The limiting reactant would be Cu and the excess reactant would be S.
Stoichiometric reactantFrom the equation:
2Cu + S → Cu2S
Mole ratio of Cu to S = 2:1
Mole of 40.2 g Cu = 40.2/63.55
= 0.63 moles
Mole of 14.1 g of S = 14.1/32.07
= 0.44 moles
Equivalent mole of Cu = 0.44 x 2 = 0.88 moles
Thus, Cu is limiting while S is in excess.

What could happen to homeostasis if the nervous system and the endocrine system stop communicating? Use one specific example in your answer.
Answer:
What could happen if the nervous system and the endocrine system stopped communicating is that body regulation functions would be lost, constituting the loss of organic balance or homeostasis.
Explanation:
There is a close relationship between the nervous and endocrine systems, or what is also known as the neuroendocrine system.
The nervous system is in charge of the regulation of all the vital functions, receiving external information, processing it and elaborating an adequate response. When it comes to the internal functions of the organism, the endocrine system receives orders from the nervous system to regulate them and maintain homeostasis.
If the communication between Nervous system and the endocrine system did not exist, there would be no way to regulate many functions and the organism would lose its ability to maintain internal balance.
An example of this would be the function of vasopressin or antidiuretic hormone (ADH). This hormone is produced by the hypothalamus and released by the neurohypophysis, being its main function the regulation of the hydroelectrolytic balance. If the communication between both systems did not exist, the function of ADH would not be possible, and the hydroelectrolytic balance would be lost.
If there is no communication between Nervous system and the endocrine system, there would be no way to regulate many functions and the organism would lose its ability to maintain internal balance.
⇒For example:
The activity and role of the adrenal glands in response to stress provide an excellent example of interdependency of the nervous and endocrine systems and if there is no communication between the two systems thus there will be no activity of adrenal glands.

13.9 grams
72.8 grams
27.8 grams
146 grams
If 45.0 grams of magnesium hydroxide is heated, the amount of water that will be produced would be 13.90 grams
Stoichiometric calculationsFrom the equation of the reaction:
Mg(OH)₂ → MgO + H₂O
The mole ratio of Mg(OH)₂ to H₂O is 1:1
Mole of 45 grams Mg(OH)₂ = 45/58.33 = 0.77 moles
Thus, the equivalent mole of H₂O produced would also be 0.77 moles.
