Answer: Distillation can be used to separate and collect a liquid from a solution. Distillation can also be used to soften water as the water evaporates as it is heated and the ions are left behind. Hard water can be softened by adding sodium carbonate (washing soda) or by passing the water through an ion-exchange column.

Answer:

5 moles S x (36.02 g S/mole S) = 180.1 grams of S

Explanation:

The periodic table has mass units for every element that can be correlated with the number of atoms of that element.  The relationship is known as Avogadro's Number.  This number, 6.02x[tex]10^{23}[/tex] , is nicknamed the mole, which scientists found to be a lot more catchy, and easier to write than  6.02x[tex]10^{23}[/tex].  The mole is correlated to the atomic mass of that element.  The atomic mass of sulfur, S, is 36.02 AMU, atomic mass units.  But it can also be read as 36.02 grams/mole.

This means that 36.02 grams of S contains 1 mole (6.02x[tex]10^{23}[/tex]) of S atoms.

This relationship holds for all the elements.  Zinc, Zn, has an atomic mass of 65.38 AMU, so it has a "molar mass" of 65.38 grams/mole.  ^5.38 grams of Zn contains 1 mole of Zn atoms.  

And so on.

5.0 moles of Sulfur would therefore contain:

(5.0 moles S)*(36.02 grams/mole S) = 180.1 grams of S

Note how the units cancel to leaves just grams.  The units are extremely helpful in mole calculations to insure the correct mathematical operation is done.  To find the number of moles in 70 g of S, for example, we would write:

(70g S)/(36.02 grams S/mole S) = 1.94 moles of S.  [Note how the units cancel to leave just moles]

Two atoms of element Q mixed with element E​

Answers

Both the elements combine together due to incomplete outermost shell.

Two atoms of element Q mixed with element E​ in order to achieve stability because both the elements have incomplete outermost shell which make them very reactive. In element E we can see that it has 7 electrons while on the other hand, element Q has 5 number of electrons.

For gaining stability, each element has to reach 8 electrons so that's why both the elements react with each other and get stability so we can conclude that both the elements combine together due to incomplete outermost shell.

D. A warm front brings rain in humid air on occasion, but a cold front brings thunderstorms in summer.

A warm front is a phenomenon in which a warm air mass replaces a cold air mass, creating fog and rain on one occasion. While the cold front is the replacement of a warm air mass by a cold air mass changing the pressure and creating a thunderstorm in the middle of summer. The warm front happens in zones close to the equator and the cold fronts happen in almost every place.

The particles in a metal are held together by strong __________ bonds. What word describes the type of bond to complete this sentence?

Answers

Answer:

metallic

Explanation:

The dislocated electrons moving around the protons create opposite charges with electrostatic attraction between them that are very strong, and are called metallic bonds.

The particles in a metal are held together by strong metallic bonds . The metals forms crystalline solids with highly ordered  lattice structure.

What are metals?

Metals are electropositive elements. They are rich in electrons and easily donate their electrons with non-metals to form ionic bonds. Metals gain  positive charge by losing electrons.

Metals in periodic table are classified as s block elements that are alkali metals and alkaline earth metals and d-block elements that are transition metals.

Metals forms highly ordered crystal lattice 3 D structures  in which metal ions negative ions or electrons are bonded by strong intermolecular force called metallic bonds and the free electrons are located in the interstices.

These electrons can delocalize and conduct thermally and electrically.Hence, the bond which hold the particles in a metal is called metallic bond.

for the reaction 2nh3(g)↽−−⇀ 3h2(g)+n2(g), if 15.8 grams of ammonia produced 1.87g of hydrogen, what was the percent yield

Answers

Answer:

75%

Explanation:

So, the reaction will consume 1 mole of hydrogen gas and produce

1mole H2⋅2 moles NH33moles H2=0.667 moles NH3

at 100% yield. This represents the reaction's theoretical yield.

Now, you know that the reaction produced 0.50 moles of ammonia. This represents the reaction's actual yield.

In order to find the percent yield, you need to figure out how many moles of ammonia are actually produced for every 100 moles of ammonia that could theoretically be produced.

You know that 0.667 moles will produce 0.50 moles, so you can say that

100moles NH3.in theory⋅0.50 moles NH3.actual0.667moles NH3.in theory=75 moles NH3.actual

Therefore, you can say that the reaction has a percent yield equal to

% yield = 75%
