Answer: To 5 ZnSO4 is I think 1 sulfur atom and 6 total

to Li2SO4 i think it is 1 sulfur atom 7 total

to Al2(SO3)3 I think its 3 sulfur atom 17 total

Explanation: I could be wrong

The number of the sulfur atom in \(\rm \bold{ZnSO_4}\) is 1, and the total number of atoms is 6.

In the structure of \(\rm \bold{Li_2SO_4}\), the number of sulfur atom is 1, and the total number of atom is 7 atoms.

In the structure \(\rm \bold{Al_2(SO_3)_3}\), the number of sulfur atom is 3, and the number of total atoms are 14.

The number of atoms can be calculated by the molecular formula. The subscript to the atom gives the idea about the number of atoms.

The number of sulfur atom = 1

Total number of atoms = 1 Zn atom + 1 Sulfur atom + 4 Oxygen atom

Total number of atoms = 6 atoms

Total number of Sulfur atom = 1

Total number of atoms = 2 Li atoms + 1 Sulfur atom + 4 Oxygen atom

Total number of atoms = 7 atoms

Total number of sulfur atoms = 3

Total number of atoms = 2 Al atoms + 3 sulfur atoms + 9 Oxygen atoms

Total number of atoms = 14 atoms.

Answer:

Sodium bromide is a chemical combination of bromine and iodine while sodium iodide is made up of sodium and iodine,you can also look at the difference in terms of boiling and melting poins

Iodide is a catalyst, and the reaction is a catalytic reaction. This is consistent with the experimental data that the iodide ion concentration does not change throughout the reaction. Hence, the mechanism proposed is consistent with the data.

Here is a mechanism that is consistent with the data.

Step 1: Iodide ions, I⁻, react with H₂O₂ to produce iodine and water 2 I⁻ + 2 H₂O₂→ I2 + 2 H₂O + 2 OH⁻

Step 2: Iodine, I₂, reacts with thiosulfate ions, SO3²⁻, to produce iodide ions and tetrathionate ionsI2 + 2 SO₃²⁻ → 2 I⁻ + S₄O₆²⁻

Step 3: The tetrathionate ions, S₄O₆²⁻, react with iodide ions, I⁻, to produce sulfite ions, SO₃²⁻, and thiosulfate ions, S₂O₃⁻  S₄O₆²⁻ + 2 I- → 2 SO₃²⁻ + 2 S₂)₃²⁻

The overall reaction can be written as follows: 2 H₂O₂ + S₄O₆²⁻ + 2 I⁻ → 2 SO₃²⁻+ 2 H₂O + 2 OH⁻

We can see that the iodide ions are being regenerated in Step 2. This suggests that iodide is a catalyst, and the reaction is a catalytic reaction. This is consistent with the experimental data that the iodide ion concentration does not change throughout the reaction. Hence, the mechanism proposed is consistent with the data.

To find the volume of the coin, simply subtract the initial volume (water only) from the ending volume (water + coin). To measure the mass, take a dry coin and place it on an electronic scale. Density = mass / volume, so divide the mass by the volume to calculate the density of the coin.

The thermodynamic quantity that expresses the extent of randomness in a system is entropy.

Entropy is a measure of the disorder or randomness in a system, and it is denoted by the symbol "S." It quantifies the distribution and arrangement of energy and particles within a system. An increase in entropy indicates an increase in disorder, while a decrease in entropy suggests a decrease in randomness. It is important to note that entropy is a state function, meaning it depends only on the current state of the system and not on the path taken to reach that state. In summary, entropy is the thermodynamic quantity that reflects the level of randomness or disorder in a system.

Whether or not such a reaction occurs can be determined using the solubility principles for typical ionic solids. Because not all water reactions result in precipitates, one must first consider the solubility criterion before determining the condition of the products and formulating a net ionic equation.

America is just one of the many countries on this planet, and compared to them and the rest of Earth, America takes up a very little percentage of energy.  Although, America's energy usage levels are increasing daily.

In a covalent bond, the bond can be either polar or nonpolar.

Polar bonds occur when two atoms of different electronegativity bond together, creating a molecule with a positive and negative end. The more electronegative atom attracts the electrons closer to its nucleus, resulting in a partial negative charge, while the less electronegative atom has a partial positive charge. Examples of polar molecules include water and hydrogen chloride. Nonpolar bonds occur when two atoms of similar electronegativity bond together, creating a molecule without a positive or negative end. The electrons are evenly shared between the two atoms, resulting in a neutral molecule. Examples of nonpolar molecules include carbon dioxide and methane. The polarity of a bond determines the physical and chemical properties of a molecule, including its solubility and reactivity.

To solve this question, we need to use the following formula:

pH = - log[H3O+] or pOH = -log [OH-]

and pH = 10 - pOH or pOH = 10 - pH

Step 1: Let's use first

pOH = 10 - pH

pOH = 10 - 6.67

pOH = 3.33

Step 2: Let's use pOH = -log [OH-]

pOH = -log [OH-] is equal to 10^-pOH = [OH-]

so we have pOH = 3.33

10^-3.33 = [OH-]

[OH-] = 4.68 x 10^-4 mol/L

What is the weight of the ethyl alcohol that exactly fills a 200.0 mL container the density of ethyl alcohol is 0.789 g ml?

Density review

A

B

What is the weight of the ethyl alcohol that exactly fills a 200.0 mL container? The density of ethyl alcohol is 0.789 g/mL.

g = (0.789 g/mL) (200.0 mL) = 158 g

Answer:

\(\boxed {\tt 197.25 \ grams }\)

Explanation:

The density formula is:

\(d=\frac{m}{v}\)

Rearrange the formula for m, the mass. Multiply both sides of the equation by v.

\(d*v=\frac{m}{v} *v\)

\(d*v=m\)

Mass can be found by multiplying the density and volume. The density of ethyl alcohol is 0.789 grams per milliliter. The alcohol fills a 250 milliliter graduated cylinder, so the volume is 250 milliliters.

\(d= 0.789 \ g/mL \\v= 250 mL\)

Substitute the values into the formula.

\(0.789 \ g/mL * 250 \ mL=m\)

Multiply. Note that the milliliters, or mL will cancel each other out.

\(0.789 \ g * 250=m\)

\(197.25 \ g=m\)

The mass of the ethyl alcohol is 197.25 grams.
