Need Help ASAP..... (0.567 Liters Of H2O Is How Many Moles Of H2O? HINT: 1 ML H20 = 1 GramH20)

Answers

Answer 1

Answer:

31.5 moles

Explanation:

Volume of H2O = 0.567 L

Number of mole of H2O =.?

Next, we shall convert 0.567 L to millilitres (mL). This can be obtained as follow:

1 L = 1000 mL

Therefore,

0.567 L = 0.567 L × 1000 mL / 1 L

0.567 L = 567 mL

Thus, 0.567 L is equivalent to 567 mL.

Next, we shall convert 567 mL to grams (g). This can be obtained as follow:

1 mL of H2O = 1 g

Therefore

567 mL of H2O = 567 g of H2O

Finally, we shall determine the number of mole in 567 g of H2O. This can be obtained as follow:

Mass of H2O = 567 g

Molar mass of H2O = (2×1) + 16

= 2 + 16 = 18 g/mol

Mole of H2O =?

Mole = mass /Molar mass

Mole of H2O = 567 /18

Mole of H2O = 31.5 moles

What type of reaction heats the water to generate steam in a nuclear power plant

Answers

Fission! Nuclear power plants heat water to generate steam. The steam is used to spin big turbines that create electricity. Nuclear power plants use heat produced during nuclear fission to heat water which becomes steam. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. Hope this helps!

Which reason best explains why metals are malleable?
A. because they have delocalized electrons
B. because they have localized electrons
C. because they have ionic bonds
D. because they have rigid bonds

Answers

Answer:

A

Explanation:

because they have delocalized electrons

Metals are malleable because they have delocalized electrons which are capable of forming ionic bonds.

What is an ionic bond?

Ionic bond or electrovalent bond is a type of bond which is formed between two elements when there is an exchange of electrons which takes place between  the atoms resulting in the formation of ions.

When the atom looses an electron it develops a positive charge and forms an ion called the cation while the other atom gains the electron and develops a negative charge  and forms an ion called the anion.

As the two atoms are oppositely charged they attract each other which results in the formation of a bond called the ionic bond.Compounds having ionic bonds are malleable and have high melting points.They are also brittle in nature.

1. A camper named Bob ran into aliens on a trail. Bob made friends with the aliens so he could
steal their treasure of 1 zygot.
1 zygot = 3 trigots
3 trigots = 2 bigots
4 bigots = 1 gram gold
How many grams of gold did Bob take from the aliens?

Answers

Answer : The number of grams of gold Bob take from the aliens will be 0.5.

Explanation :

As we are given that:

1 zygot = 3 trigots

3 trigots = 2 bigots

4 bigots = 1 gram gold

Now we have to determine the number of grams of gold Bob take from the aliens.

The number of grams of gold Bob take from the aliens will be equal to:

[tex]\frac{1\text{ zygot}}{1}\times \frac{3\text{ trigots }}{1\text{ zygot}}\times \frac{2\text{ bigots }}{3\text{ trigots }}\times \frac{2\text{ gram gold}}{4\text{ bigots }}[/tex]

= [tex]\frac{6}{12}[/tex] gram gold

= [tex]\frac{1}{2}[/tex] gram gold

=  0.5 gram gold

Hence, the number of grams of gold Bob take from the aliens will be 0.5.

Find the number of moles of iron atoms obtain
from 320kg of iron (3) oxide​

Answers

Answer:

320 kg  of iron(III) oxide contain 4007.76 moles of iron atom.

Explanation:

Given data:

Mass of iron(III) oxide = 320 kg (320000 g)

Number of moles of iron atoms = ?

Solution:

First of all we will calculate the number of moles of iron(III) oxide.

Number of moles = mass/molar mass

Number of moles = 320000 g/ 159.69 g/mol

Number of moles = 2003.88 mol

1 mole of Fe₂O₃ contain 2 moles of iron atom.

2003.88 moles of  Fe₂O₃ contain,

2003.88 ×2 = 4007.76 moles of iron atom.

in an experiment it was found that the total charge on an oil
drop was 5.93 X 10^-18 C How many negative charges does
the drop contain? (#51)

Answers

Answer:

37 negative charges.

Explanation:

We're being asked to determine how many negative charges a drop contains from an oil drop experiment where the total charge was 5.93x10-18 C. The drop contains 37 negative charges.

It was stated and identified that we are to attempt question #51 alone.

From the given information;

The total charge on an oil drop = 5.93 × 10⁻¹⁸ C

According to Oil drop experiment carried out by Robert Milliken in (1910);

In the oil drop laboratory experiment, It was possible for Him to substitute oil for water (because water quickly evaporate). Robert Milikan adjusted the electrical voltage among the two metal plates while the oil drop continues to drop until it stopped. When the drop was stopped, the gravitational downward force on the oil drop was equivalent to the electrical upward force on the charges thereby enabling Robert Millikan to be able to estimate the electrical charge drop.

Robert Milliken identified that the magnitude of a single negative electron charge is:

= 1.6 × 10⁻¹⁹ C

If in an experiment, the total charge =  5.93 × 10⁻¹⁸ C

Then;

The number of negative charges in the oil drop can be calculated as;

[tex]\mathbf{=\dfrac{5.93 \times 10^{-18}}{1.6 \times 10^{-19}}}[/tex]

= 37.063 negative charges

Therefore, we can conclude that the numbers of negative charges contained in the total drop = 37.063.

A sample is left on the desk over several hours. On examination, the crystals appear moist, andliquid is forming around them. The compound is classified as:

a. Stableb.
b. Deliquescent
c. Efflorescentd.
d. Hygroscopic

Answers

Answer:

c. Efflorescent

Explanation:

Some hydrated salts, when exposed to the atmosphere, give off part of all of their water of crystallization spontaneously to form a lower dehydrated or anhydrous salt. Such salts are known as efflorescent and the phenomenon is called Efflorescence.

Efflorescence occurs when the hydrate's aqueous vapor pressure is greater than the water vapor's partial pressure in the air. For example, because the vapor pressures of washing soda (Na2CO3·10H2O) and Glauber's salt (Na2SO4·10H2O) normally exceed that of the water vapor in the atmosphere, these salts effloresce (i.e., lose all or part of their water of hydration), and their surfaces assume a powdery appearance.

According to the concept of solubility and properties of ionic compounds, magnesium sulfate and sodium nitrate dissolve in water.

What is solubility?

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.
