Answer:

11.75 g H2O

Explanation:

3CaCO3 + 2H3PO4 --> Ca3(PO4)2 + 3H2O + 3CO2

MM H2O = 18.02 g/mol

MM CaCO3 = 100 g/mol

? g H2O = mass CaCO3 x (1 mol CaCO3/MM CaCO3) x (3 moles H2O/3 moles CaCO3) x (MM H2O / 1 mol H2O) = (65.2/100) x 18.02 = 11.75 g H2O

Answer: NO

Explanation:

As per the given balanced equation, 2 moles of NO reacts with 2 moles of CO. Hence, 3 g or 1.07 moles of CO needs to react with the same number of moles of NO. But we have only 3 g or 0.1 mole of NO. Hence, NO is the limiting reactant.

A limiting reactant in a reaction is the reactant which is fewer in amount or consume early without complete reaction with other reactants. Hence, as soon as this reactant is consume, the reaction stops.

Given 2 moles of NO reacts with 2 moles of CO.

molar mass of NO =  30 g/mol

molar mass of CO = 28 g/mol.

Number of moles in  3 g of CO = 3/28 = 1.07 moles

number of moles in 3 g of NO = 3/30 = 0.1 moles.

1.07 moles of CO needs 1.07 moles of NO. But only 0.1 moles are present.

Therefore, NO is the limiting reactant in this reaction.

Answer:

Genotype = genetic makeup or allele combination

phenotype = physical appearance

homzygous = both alleles are the same

heterozygous = both alleles are different

dominant allele = represented by a capital letter

recessive allele = lowercase letter

More reactants have more atoms to react to form more products.

More reactants have more atoms to react to form more products in a chemical reaction.

This is the process which involves two or more molecules known as reactants collide with the right orientation and force to form a new product.

Increase in reactants means presence of more molecules involved in the reaction thereby leading to the formation of more product.

Answer:

There are 2 lithium atoms in the ionic compound lithium oxide, Li₂O

Explanation:

The charge of ions formed by lithium = 1⁺

The charge of ions formed by oxygen = 2⁻

In the ionic compound lithium oxide having 1 atom of oxygen, we have;

For the compound to be electronically neutral, the sum of the charges of the atoms in the ionic compound is zero

The charge of 1 atom of oxygen in the lithium oxide compound + The charge of the 'n' number of lithium atoms in the lithium oxide compound = 0

∴ 2⁻ + n × 1⁺ = 0

n × 1⁺ = 0 - 2⁻ = 2⁺

n = 2⁺/(1⁺) = 2

n = 2

The number of lithium atoms in the lithium oxide compound, n = 2

Therefore, there are two lithium atoms in the ionic lithium oxide (Li₂O) compound

Answer:

it is the moisture in the air

Explanation:

if we buy a dehumidephire we see that it collets water from the air

Answer:

Humidity describes the amount of water vapor or water molecules in the air. Weather scientists use the term “relative humidity,” which Joe Sobel, a meteorologist and senior vice president at Accuweather described as “a comparison of the amount of moisture in the air versus the amount of moisture the air could hold.”

Answer:

This is a mixture.

Explanation:

While you can no longer see the salt when it's dissolved, it's still there! It's just in tiny, tiny, invisible to the eye molecules. It's now a mixture of H20 molecules and NaCl molecules in a solution :)

The water doesn't bond to the salt, so it's not a compound.

It's not just one element, it's a mixture of many!

It's not a pure substance since it's NaCl AND H2O.

Answer:

c.) 22.4 L/1 mole

Explanation:

Using the general gas law equation as follows:

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K)

The standard values for a gas are as follows:

Standard pressure of a gas = 1 atm

Standard temperature of a gas = 273K

According to the information in the question, n = 12.3 moles

Using PV = nRT

V = nRT/P

V = 12.3 × 0.0821 × 273/1

V = 275.68 L

Based on this value of volume in liters for 12.3moles of Br gas, the volume per mole at standard temperature and pressure will be 275.68/12.3 = 22.4 Litres per mole. Hence, the answer is 22.4 L/1 mole.

Answer:

9.03×10²³ molecules of H₂O

Explanation:

To solve this, we need to propose the reaction

NH₄ClO₄  →  ammonium perchlorate

Al → Aluminum

Those are the reactants; the reaction is:

6NH₄ClO₄  +  10Al →  5Al₂O₃ + 3N₂ + 6HCl + 9H₂O

Then, water is one of the products. If we see the reaction, is a redox type.

Ratio is 6:9. In conclussion:

6 moles of ammonium perchlorate can produce 9 moles of H₂O

Then 1 mol of salt, may produce (1 . 9)/6 = 1.5 moles of water

Let's count the molecules:

1.5 mol . 6.02×10²³ molecules /mol = 9.03×10²³ molecules of H₂O

Under good conditions the seedling can thrive in soil that does not have any clay as long as it gets the proper nutrients and right amount of sunlight/water that it needs. Clay in soil can provide the nutrients necessary for seedlings to thrive but can also cause many negatives. One such con of using clay is that it does not absorbe water very well, this ultimately causes the soil to become waterlogged and drowns the plants as no oxygen can pass through. This would ultimately kill the plants.

Answer:

In fluorine, the electrons are tightly held to the nuclei. The electrons have little chance to wander to one side of the molecule, so the London dispersion forces are relatively weak. At a low enough temperature the molecules will all be solids. At a high enough temperature they will all be gases.
