Explain why flourine forms a negative ion more easily than chlorine.​

Answers

Answer 1

Answer:

the electron is outermost

Explanation:

shell of a flourine are closer together .

Explain Why Flourine Forms A Negative Ion More Easily Than Chlorine.
Answer 2

Answer:

The electron gain enthalpy of chlorine is more negative than fluorine. This is because fluorine is smaller in size than chlorine. Thus the extent of electron-electron repulsion would be more in fluorine than in chlorine. Because of this, the incoming electron would face more repulsion in fluorine than in chlorine.

The magnesium atom has 12 electrons arranged 2,8,2. What must the atom do to become stable? gain 6 electrons a.lose 6 electrons b.gain 2 electrons c.lose 2 electrons

Answers

Answer:

The answer is Gain 6 electrons.

Explanation: The reason for this is that for electrons to be stable, you need a valence shell of 8 electrons. Since it is arranged 2, 8, 2 , the outer shell is 6 less than 8 meaning it needs to gain 6 electrons.

Paper clips are made of stainless steel. Steel is a mixture. There are different kinds of steel that have slightly different ratios of substances. Stainless steel is made of iron mixed with high-density metals. Carbon steel is made of iron mixed with carbon, an element with a lower density than metals. Would you expect the density of stainless steel and carbon steel to be the same? Why or why not? Font Sizes

Answers

No, firstly bc stainless steel and carbon steel mixed with different things, high-density metals and carbon.

High-density metals and carbon both has different density which will affect the steel when they combined with iron. So it cant be the same.

How did Louis Pasteur’s experiments lead to new scientific understandings of germs? A.Experiments with cooking food showed that disease-carrying germs in food could be killed when heated. B.Experiments with different magnification lenses showed that germs were real and could be observed. C.Experiments with animals showed that dominant genes could lead to risks of disease. D.Experiments with shallow dishes showed that groups of germs could be grown so they could be seen without microscopes.

Answers

Answer:

A.Experiments with cooking food showed that disease-carrying germs in food could be killed when heated.

Explanation:

Louis Pasteur (1822-1895) is regarded as the father of immunology. He extensively studied microbes and their effect on food. He discovered that microorganisms were responsible for the spoilage of food.

His most important discovery was the fact that heating wine to 55°C will lead to the death of microorganisms and prevented wine from spoiling and did not affect its taste. This process is known as pasteurization.

> So, to fill this shell, will it be easier for sodium to steal
seven more electrons from another atom, or will it be easier
for sodium to give up that one electron and get rid of that third
shell? Sodium is simply going to give away that last electron.
This means that it will lose an electron (negative charge) but
will keep the same number of protons (positive charges).
What will the sodium ion's overall charge be now?
40
- Exploring Anatomy & Physiology in the Laboratory

Answers

Answer:

+1

Explanation:

Sodium has one electron in its outermost shell. Sodium can not be able to accept seven electrons because the energy required for that process is very high. Sodium would rather loose its only valence electron to form a univalent positive ion Na^+.

This is an easier process. When sodium looses one electron, it now has a charge of +1.

A student describes the motion of particles in each of the four different states of matter

State 1: particles that are charged move freely
State 2: particles move freely at high speed
State 3: particles are locked in place
State 4: particles slide past one another

which state describes solids?

Answers

State 3 describes solids

State 3: particles are locked in place describes the solid state exactly.

What is Solid State ?

The physical characteristics of matter in which molecules or atoms are unable to move freely and are instead required to maintain their borders independently and in fixed connection to one another.

One of the four basic states of matter is solid.

The least energy molecules are those that form solids and are tightly grouped.

The solid's defining structural rigidity and resistance to external pressure.

Solids have precise mass, volume, and shape as well as compact arrangements of their constituent particles. Between molecules, there is not much intermolecular space.

Therefore, State 3: particles are locked in place describes the solid state exactly.

What is the percent yield for a certain reaction when 56.8 g of product was
obtained in the lab, but the theoretical yield was 64.4g?

Answers

Answer:

88.20%

Explanation:

% yields =( experimental yield /theoretical yield )x100%

           = ( 56.8 ÷ 64.4 ) x100%

            = 88.20%

The percent yield for the given reaction where in the product obtained is 56.8 g is 88.19%.

What is percent yield?

Percent yield is defined as the ratio of actual yield to the theoretical yield multiplied by 100. If the actual and theoretical yield are same then the percent yield is 100%.If actual yield is less than the theoretical yield then the percent yield is less than 100%.Reason of this condition arising is the incompletion of reaction or loss of sample during recovery process.

In cases where percent yield is over 100% it indicates that more sample is recovered than the predicted amount.This condition arises when there are other simultaneous reactions taking place leading to the formation of product. It can also arise if there is incomplete removal of impurities from the sample .In the given example , percent yield=56.8/64.4×100=88.19%.

Thus, the percent yield of reaction is 88.19 %.
