Fission is the of a heavy nucleus into two smaller nuclei. This process is used in __________ .

Answers

Nuclear Fission

Nuclear fission, subdivision of a heavy atomic nucleus, such as that of uranium or plutonium, into two fragments of roughly equal mass. The process is accompanied by the release of a large amount of energy. In nuclear fission the nucleus of an atom breaks up into two lighter nuclei.

Nuclear fission is a process where the nucleus of an atom is split into two or more smaller nuclei, known as fission products. The fission of heavy elements is an exothermic reaction, and huge amounts of energy are released in the process.

Convert 21 grams of radon into atoms of radon.

Answers

A 1.60 g calcium supplement that contains 37.8% Ca by mass, contains 1.51 g of CaCO₃.

We want to calculate the mass of CaCO₃ in a 1.60 g supplement. We need to consider the following relationships.

The mass percent of Ca is 37.8%, that is, there are 37.8 g of Ca every 100 g of supplement.The molar mass of Ca is 40.08 g/mol.The molar ratio of Ca to CaCO₃ is 1:1.The molar mass of CaCO₃ is 100.09 g/mol.

In order to complete a reaction, a chemist needs to react 4 moles of aluminum atoms with 3 moles of oxygen molecules. How many grams of aluminum would be required to make this happen?

Answers

Answer:

4 Al + 3 O2 → 2 Al2O3

To react with 4 moles of Al, (3×32) g oxygen is required.

So, to react with 2.4 moles of Al, {(3×32)/4} × 2.4 = 57.6 g oxygen is required.

what is a nucleus and what are the functions?

Answers

nucleus, in biology, a specialized structure occurring in most cells (except bacteria and blue-green algae) and separated from the rest of the cell by a double layer, the nuclear membrane. This membrane seems to be continuous with the endoplasmic reticulum (a membranous network) of the cell and has pores, which probably permit the entrance of large molecules. The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information

If 0.600mol of chloride gas reacted with 0.500mol of aluminium metal to produce aluminium chloride,which reactant is in excess?how many moles of aluminium chloride can be produced during the reaction.

Answers

Answer:

The balanced chemical equation: 2 Al + 3Cl2→ 2 AlCl3

Mole-mole relationship: 2 moles Al + 3 moles Cl2→ 2 moles AlCl3

Given: 0.600 moleCl2; 0.500 mole Al

Required: Excess reactant___; Number of moles of AlCl3 produced__

Solution: Use dimensional analysis using the mole-mole rel

0.600 mole Cl2 * 2 moles Al/3 moles Cl2 = 0.4 mole Al

0.5 mole Al* 3 moles Cl2/2 moles Al = 0.75 mole Cl2

Based on the given:

0.6mole Cl2 + 0.4 mole Al ( this is possible based on the given)

0.5mole Al + 0.75 mole Cl2 (this is not possible because the given is only 0.600 mole of Cl 2)

Answer: Excess reactant is Al; Limiting reactant is Cl2

The amount of AlCl3 produced = 0.6 mole Cl2 + 0.4 mole Al = 1.0 mole AlCl3

Which two characteristics determine the strength of the gravitational force
between two objects?

B. The distance between the objects' surfaces
C. The amount of matter in the objects
D. The total volume of the objects

Answers

Answer:

A and C

Explanation:

I took the test

The distance between the objects' centers and The amount of matter in the objects are two characteristics determine the strength of the gravitational force between two objects.

What is Gravitational force?

All objects with mass or energy are attracted to one another by gravity, which is a fundamental interaction.

The electromagnetic force, the weak interaction, and the strong interaction are all significantly stronger than gravity, which is by far the weakest of the four fundamental interactions.

As a result, it has no appreciable impact on subatomic particle level phenomena. However, at the macroscopic level, gravity is the most important interaction between objects and governs the motion of planets, stars, galaxies, and even light.

Therefore, The distance between the objects' centers and The amount of matter in the objects are two characteristics determine the strength of the gravitational force between two objects.

E) This is not an oxidation/reduction type of reaction

Answers

Answer:

E) This is not an Oxidation/ Reduction type of reaction

Explanation:

Oxidation involves the loss of electrons while reduction involves the addition of electrons. None of the elements change their oxidation number in the reaction, so this is not an oxidation/reduction type of reaction.

The addition of oxygen and the removal is electrons is called oxidation. In a reaction that has both the process is called the redox reactions.

The correct answer to the question is option E

In this reaction, not any elements have the loose and gain the electrons in order to tell the oxidation and reduction.

This reaction is a neutralization reaction.

Hence, the correct answer is E that is not an oxidation/reduction type of reaction.

which best describes how heat energy moves within the system?

Answers

Answer: B

Heat always travels from warmer areas to cooler areas in the form of radiation or convection currents due to the temperature difference. You could kind of think of this movement like diffusion: travelling from a higher concentration to a lower one (if you take biology). This is how a gas heats up a pan on the stove or a radiator warms a room
