At night, the demand for electricity supplied by a fission nuclear reactor decreases. How is the fission nuclear reaction controlled to avoid overproduction of electricity? The temperature of the reactor is lowered because high temperature and pressure are needed. The temperature of the reactor is raised because the reaction slows down at higher temperatures. The exposure between the fuel rods and a neutron-absorbing material is increased. The exposure between the fuel rods and a neutron-absorbing material is reduced.

Answers

Answer:

The exposure between the fuel rods and a neutron-absorbing material is increased.

Explanation:

The exposure between the fuel rods and a neutron-absorbing material is increased.

A nuclear reactor produces energy via a fission reaction. A fission reaction is a self sustaining reaction.

The nuclear fuel is bombarded with neutrons. The process produces more neutrons which continues the reaction.

In order to decrease the rate of reaction, control rods are inserted. These control rods are neutron-absorbing materials.

At night when demand for electricity decreases, the exposure between the fuel rods and a neutron-absorbing material is increased so that more neutrons are absorbed in order to decrease the rate of nuclear reaction.

Which ion at ground state has the same electron configuration as an atom of neon at ground state?
1. Ca^2+
2. CI^-
3. Li^+
4. O^2-

Answers

Answer:

4. O^2-

Explanation:

O^2 has 16 electrons, while Ne has 18 electron. O^2- is a molecule that has one electrons added to each atom, meaning that there are two extra electrons. Which makes O^2 the same electron configuration as an atom of neon.

The ions having same electronic configuration as neon are Calcium, oxygen, and chlorine ion. Thus, options 1, 2, and 4 are correct.

The electronic configuration has been defined as the electron address in a atom. The electronic configuration has been based on the quantum rule for the filling of the electrons.

The number of electrons present in Neon has been 18. Thus, the ion with the presence of 18 electrons has same electronic configuration as Neon.

The number of electrons in the following ions are:

[tex]\rm Ca^{2+}=18\\Cl^-=18\\Li^+=4\\O_2^{-}=18[/tex]

The number of electrons of calcium ion and chlorine ion are similar to the number of electrons of Ne. Thus the ions having same electronic configuration as neon are Calcium, oxygen and chlorine ion. Thus, options 1, 2, and 4 are correct.

Classify each characteristic according to whether it is true for an amoeba, a clock, or both.

Answers

Answer:

Amoeba: reproduces

clock: lacks genetic material

both: has defined boundary, use energy, and have an internalized organization.

Explanation:

Amoeba is a single cell organism known as amoeboid which is a eukaryotic cell and has all the eukaryotic features such as membrane-bound organelles including the nucleus. The nucleus contains the genetic material of the amoeba cells and which is transferred to the offspring by reproduction. The cell membrane is the outer boundary of the cell use energy to perform its cellular functions.

A clock is a non-living thing that contains many small parts to make it work properly and requires energy to work. It is not a living thing so does not have genetic material. However, it has a defined boundary in it.

How many grams are in 4 moles of Calcium?

Answers

Answer:

160.32 grams of Ca or 160 if rounded

Explanation:

Multiply moles of Ca by the conversion factor (molar mass of calcium) 40.08 g Ca/ 1 mol Ca, which then allows the cancelation of moles, leaving grams of Ca.

4 mol*40.08g/mol = 160.32 grams of Ca

please give thanks by clicking heart button :)

Answer:

[tex]\boxed {\boxed {\sf 160.32 \ g, \ 160 \ g, \ or \ 200 \ g }}[/tex]

Explanation:

To convert from grams to moles, we must use calcium's molar mass, which can be found on the Periodic Table of Elements.

Calcium (Ca) Molar Mass: 40.08 g/mol

Now, we can use the molar mass as a ratio or fraction.

[tex]\frac{40.08 \ g \ Ca}{1 \ mol \ Ca}[/tex]

This fraction can be multiplied by the number of moles, which is 4.

[tex]4 \ mol \ Ca * \frac{40.08 \ g \ Ca}{1 \ mol \ Ca}[/tex]

When we multiply, the moles of calcium will cancel each other out.

[tex]4* \frac{40.08 \ g \ Ca}{1}[/tex]

Since the fraction is over 1, we can just remove the denominator and write a simply multiplication equation.

[tex]4* 40.08 \ g \ Ca[/tex]

[tex]160.32 \ g \ Ca[/tex]

Depending on the teacher's instructions, the answer can be left as is or rounded.

If we round to the technically correct number of significant figures, it would be 1, because the original measurement of 4 moles has 1 sig fig. This would 200 grams, but that's a large amount to round.

We could also round to the nearest whole number. The 3 in the tenth place tells us to leave the whole number as it is. This would be 160 grams.

The answer could be 160.32 grams, 160 grams, or 200 grams, depending on rounding and significant figures.

Explaining dark matter and black holes

Here are six big questions about our universe that current physics can’t answer:

What is dark energy, the mysterious energy that appears to be accelerating the expansion of the universe?

What is dark matter, the invisible substance we can only detect by its gravitational effect on stars and galaxies?

What caused inflation, the blindingly fast expansion of the universe immediately after the Big Bang?

For that matter, what caused the Big Bang?

Are there many possible Big Bangs or universes?

Is there a telltale characteristic associated with the death of a universe?

Despite the efforts of some of the world’s brightest brains, the Standard Model of particle physics – our current best theory of how the universe works at a fundamental level – has no solution to these stumpers.

A compelling new theory claims to solve all six in a single sweep. The answer, according to a paper published in European Physical Journal C by Herb Fried from Brown University and Yves Gabellini from INLN-Université de Nice, may be a kind of particle called a tachyon.

Tachyons are hypothetical particles that travel faster than light. According to Einstein’s special theory of relativity – and according to experiment so far – in our ‘real’ world, particles can never travel faster than light. Which is just as well: if they did, our ideas about cause and effect would be thrown out the window, because it would be possible to see an effect manifest before its cause.

Explanation:

Due to travelling faster than light, dark matter has a higher than usual mass in relation to its resting mass, thus accounting for the large 'missing' mass around galaxies. ... Dark matter is therefore non-baryonic, travelling faster than light and has a mass half that of a photon...

What is used to determine the number of each atom in an ionic formula

Answers

Answer:

The charge carried by each ion (oxidation state of each atom)

Explanation:

If we have an ionic compound and we want to write its formula, we must first know the magnitude of charge on each ion (shown as oxidation state of the atoms involved) because the magnitude of charge on each ion is eventually crisscrossed and gives the subscript (number of atoms) for each atom in the formula.

For instance, let us write the formula of calcium bromide. Ca has a charge of +2 while Br has a charge of -1. If we exchange the charges and ignore the signs such that the crisscrossed charges form subscripts we can now write; [tex]CaBr_{2}[/tex].

How do unbalanced forces cause a change in speed, direction, and position of an object?

Answers

Answer:

But its motion is not changing. This is because the forces acting on it from opposite sides are exactly the same size. An unbalanced force can change an object's motion. ... An unbalanced force acting on a moving object could make the object change direction, change speed, or stop moving.

The unbalanced forces are unequal in magnitude. They change the state of motion of the object. The pushing or pulling of an object can generate unbalanced forces and cause change in the direction, and position of an object.

What is an unbalanced force?

The two forces of unequal magnitudes and they act on an object simultaneously such that the net force is not zero are defined as the unbalanced forces. The body acted upon by the unbalanced forces changes its state of motion.

The unbalanced forces are the opposite of a balanced force. An unbalanced force causes a change in motion, speed, direction, or movements. Because of unequal force or strength which is applied to one side of an object.

In the case of unbalanced forces, one side has more energy than the other. Opposite sides have forces acting against them.

Thus the unbalanced forces are out of balance and are not equal, it causes body's position to change.
