how many molecules are in SO4

Answers

Answer:

there are 5 molecules in SO⁴

Can someone help me ?

Answers

Explanation:

11. The correct option is B. The range for polar covalent bond is; 0.3 - 1.4

12. C. This is because there is uneven distribution of the charge. Unlike in the other options which are molecules of the same atoms with equal electronegativity.

13. A. Resonance structures is the correct option. It describes electrons in certain molecules or polyatomic ions where the bonding cannot be expressed by a single Lewis formula.

14. A. Lower electronegativity values means the electrons are more likely to be shared than transferred (gain/lost).

15. D. H2O is more polar than H2S because of the electronegativity of oxygen. H2O also has hydrogen bonds.

16. C. Due to the geometry of the other molecules, the polarity are cancelled.So they have a net polarity of zero.

How many grams of sodium nitrate are needed to prepare a 0.965 M sodium nitrate solution that contains 1,640 g of water?

Answers

Answer:

134.5 g

Explanation:

Let us recall that 1g of water = 1cm3 of water

Hence;

1,640 g of water =  1,640 cm3 of water or 1.64 L

This is now the volume of the solution

Now;

m/M = CV

m = mass of the solute

M = molar mass of the solute

C = concentration of the solution

V = volume of the solution

m/84.9947 g/mol = 0.965 M *  1.64 L

m = 0.965 M *  1.64 L * 84.9947 g/mol

m = 134.5 g

If an ionic compound formed between an element from the first column of the periodic table and another from the sixteenth column, you would expect the compound to include W 0 A two atoms of the element from the first column and one atom of the element from the sixteenth column. O B. one atom of the element in the first column and two atoms of the element from the sixteenth column. O C three atoms of the element from the first column and two atoms of the element from the sixteenth column. OD one atom from each of the two different elements.​

Answers

Answer:

A. two atoms of the element from the first column and one atom of the element from the sixteenth column.

Explanation:

If an ionic compound formed between an element from the first column of the periodic table and another from the sixteenth column, you would expect the compound to include two atoms of the element from the first column and one atom of the element from the sixteenth column.

The periodic table is arranged in rows and columns. The rows are periods while the columns are groups.

The first column of the periodic table contains elements that form univalent ions hence they have a valency of 1. The elements in the sixteenth column usually form divalent negative ions and have a valency of 2.

An example of an element of the first column is sodium while an example of an element of the sixteenth column is sulphur.

During ionic bond formation, there is an exchange of valency such that the formula of a compound formed between sodium and sulphur is Na2S.

Therefore, when an ionic compound formed between an element from the first column of the periodic table and another from the sixteenth column, you would expect the compound to include two atoms of the element from the first column and one atom of the element from the sixteenth column.

How many moles of CuO are needed to react with 5.9 moles of CO2

Answers

Answer:

If 5.9 moles of CO₂ react, 5.9 moles of CuO will also react.

Explanation:

The balanced reaction is:

CuO + CO₂ → CuCO₃

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

CuO: 1 moleCO₂: 1 moleCuCO₃: 1 mole

You can see that the stoichiometric relationship between CuO and CO₂ is 1: 1. In other words, for each mole of CuO that reacts, one mole of CO₂ will also react.

So if 5.9 moles of CO₂ react, 5.9 moles of CuO will also react.

Answer:

Gene, Chromosome, Nucleus

Explanation:

Gene is defined in biology as "a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring" (Oxford Dictionary).

The gene is located in the chromosomes in the nucleus of cells. The sum total of the genes that an organism inherits from its parents is called the organisms' genotype and determines certain features of the organism.

The hair colour of Mary and each of her siblings depends on the genes they received from their parents.

metal. How much Iron was required to complete this reaction?

Answers

First, you would add the products: 0.4 + 6.01 = 6.41 g
Then, to get the mass of Iron required, you would do 6.41 - 5.0 = 1.41
This is because in the conservation of mass principle it states,
mass of reactants = mass of products.

What is the molecular formula for C5H7 if its molar mass is 536 g/mol?

Answers

Answer:

(C5H7)8

Explanation:

It's empirical formula is given as; C5H7

Molar mass of carbon(C) = 12 g/mol

Molar mass of hydrogen(H) = 1 g/mol

We are told that it's molar mass is 536 g/mol.

To find the molecular formula;

Molecular formula = n × empirical formula

Thus;

n = 536/((12 × 5) + (1 × 7))

n = 8

Thus;

Molecular formula = (C5H7)8

When kci dissolved in ethanol what is the intermolecular attraction between k+ ions and ethanol molecules

Answers

Answer:

ion-dipole interaction

Explanation:

Ethanol is a polar molecule due to the presence of the polar O-H group in the molecule. This means that the molecule has a dipole moment.

The positive end of the dipole lies on hydrogen while the negative end of the dipole lies on oxygen.

When KCl is dissolved in ethanol, K^+ ions can interact with the negative end of the dipole in ethanol by ion-dipole interaction.

How many moles are in a 4.5g of Sulfur?

Answers

Answer:

~0.14

Explanation:

There are roughly ~0.14 moles in 4.5g of Sulfur. 1 mol = 32.06 g of Sulfur, so we just find the ratio and then multiply.

Answer:

[tex]\boxed {\boxed {\sf About \ 0.14 \ mol \ S }}[/tex]

Explanation:

To convert from grams to moles we must use the molar mass. This can be found on the Periodic Table.

Sulfur (S); 32.07 g/mol

We can use this number as a ratio or fraction.

[tex]\frac{ 32.07 \ g \ S }{1 \ mol \ S }[/tex]

Multiply by the given number of grams: 4.5

[tex]4.5 \ g \ S *\frac{ 32.07 \ g \ S }{1 \ mol \ S }[/tex]

Flip the fraction so the grams of sulfur cancel.

[tex]4.5 \ g \ S *\frac{1 \ mol \ S }{32.07 \ g \ S}[/tex]

[tex]4.5 *\frac{1 \ mol \ S }{32.07 }[/tex]

[tex]\frac{4.5 \ mol \ S }{32.07 }[/tex]

[tex]0.140318054 \ mol \ S[/tex]

The original measurement of grams had 2 significant figures, so our answer must have the same. For the number we calculated, that is the hundredth place.

The 0 in the thousandth place tells us to leave the 4.

[tex]0.14 \ mol \ S[/tex]

There is about 0.14 moles of sulfur in 4.5 grams.
