The correct statements are:

The limiting reactant is completely used up in the reaction.

There will be an excess of other reactants at the end of the reaction.

The limiting reactant dictates the amount of product.

Which reactant will be the limiting reactant depends on the molar ratios of all the reactants in the experiment (and the coefficients in the balanced reaction equation), so it will absolutely vary depending on the reaction setup and conditions, which is why it cannot always be the same for a given reaction.

Because the molar ratios of the reactants dictate which of them will be the limiting one, it is not true that the one with the lowest mass will always be the limiting reactant.

The molar mass of the metal Sulfide  is 83.02g/mol.  

The molar mass of Sulfide  is the addition of molar mass of Sulphur with molar mass of given metal which is given by subtract the molar mass of hydroxide from total molar mass of metal hydroxide.

The molar mass of the [tex]M(OH)_{4}[/tex] =118.97g/mol

Molar mass of Oxygen = 15.999g/mol

Molar mass of Hydrogen= 1.008g/mol

Therefore:

molar mass of [tex]M(OH)_{4}[/tex]= (molar mass of M) +4(molar mass of oxygen + molar mass of hydrogen)

118.97=(molar mass of M)+(15.999 x4)+(1.008x4)

118.97=(molar mass of M)+(63.996+4.032)

118.97-68.028=molar mass of metal(M)

molar mass of Metal=50.942 g/mol (that is Vanadium)

Molar mass of metal + molar mass of Sulphur to give metal sulfide.

50.942+32.06=83.02g/mol

Hence,  the molar mass of  Vanadium Sulfide([tex]V_{2} S_{5}[/tex] ) is 83.02g/mol.

I think it’s C because animal cells do not have a cell wall and the cell wall is unique to plant cells

When 20 grams of a salt is dissolved in 95 grams of water, the temperature of the solution decreases from 40oc to 0oc. 880 calories heat is absorbed, the Specific Heat of the solution is 1.1 Cal/goc.

delta t = T f - T i

          = 0 - 40

          = -40 degrees Celsius

c = 1.1 Cal/g degrees Celsius

m = 20 grams

heat absorbed (q) = mc(delta)t

Answer: Fe is the element that is being oxidized (oxidation number changes from +2 to +3) while Cl is the element that is reduced (oxidation number changes from +5 to -1) in the given reaction.

Explanation:

The question requires us to find the element that is oxidized and the one reduced in the following chemical reaction:

To solve this problem, we need to determine the oxidation number of all elements in the reactants and products sides, and then identify the elements that had their oxidation number increased (oxidized species) and decreased (reduced species).

To identify the oxidation numbers, we'll need to remember a few points:

- K is an alkali metal (part of group 1 in the periodic table), and it usually assumes the oxidation number +1;

- O usually presents oxidation number -2, except in a few specific cases;

- the anion (SO4) presents total charge -2 (in this anion, S presents oxidation number +6 and O, -2);

- H usually presents oxidation number +1.

Next, let's identify the oxidation number of all elements involved in the reaction, on both sides of the chemical equation. Since all compounds are neutral (i.e., they do not present charge), the sum of all oxidation numbers must be 0:

(note that the oxidation number of each element is indicated in red, above the respective element, while the contribution of this element to the molecule charge, considering the number of atoms, is represented in blue below the element).

In the image above, we can see that Cl has its oxidation number changing from +5 in KClO3 to -1 in KCl (highlighted in purple), while Fe has its oxidation number changing from +2 in FeSO4 to +3 in Fe2(SO4)3 (highlighted in green).

Therefore, we can say that Fe is the element that is being oxidized while Cl is the element that is reduced in the given reaction.

Answer:

A because density DOES have a unit

Explanation:

The molarity of the solution is 0.619 M if we dissolve 23.4 g of manganese(ii) sulfate in a volumetric flask and add water to a total volume of 500 ml.

The molarity is equal to the moles of a solute divided by the total number of liters in the solution. The molarity of a material quantifies its concentration in a given volume of solution.

Molarity is the concept that describes the relationship between moles of a certain solute and the volume of the supplied solution. To calculate your molarity, you must start with moles and volumes, moles and milliliters, and mass and volumes.

Molarity formula and units

The units of molarity are M or mol/L.

Molarity equation

M = moles solute/liters solution

Molarity = number of moles of solute divided by the volume of solution in a liter

= number of moles of solute × 1000/ volume of solution in the liter

= number of moles

= Mass/ molecular weight

= 23.4/151

= 0.155moles

Molarity = 0.155× 1000/250

= 0.619 M

The concentration of manganese ion = concentration of sulphate ion = 0.619 M

Answer: There is equal number of each type of atom on the reactant and product side.

Explanation:

If there is no change in pressure or no change in volume of the system, then the heat of the reaction will be equal to the change in internal energy of the system.

According to the first law of thermodynamics,

The total change in internal energy of the system is equal to the sum of the heat added to the system and the work done by the system.

So, we can write,

ΔH = ΔQ + W

Where,

ΔH is the heat of the reaction,

ΔQ is the heat evolved or heat given,

W is the work done by the system,

We know work by the gas is,

W = VΔP or PΔV

Where V is the volume of the gas and P is pressure of the gas.

So, for the heat of the system to be equal to that of the hear evolved in the system.

W = 0

For W to be zero,

Either, ΔV or ΔP has to be zero,

So, we can conclude that if change in the pressure of the system of the change in volume of the system is zero.

The law of magnetism states that the unlike (different) poles of a magnet would attract each other while like poles of a magnet would generally repel one another.

This ultimately implies that, two north (N) or south (S) poles of a magnet would repel one another while a north (N) and south (S) of a magnet would attract each other.

Based on the law of magnetism, we can reasonably infer and logically deduce that if this student should bring a few pieces of iron near the iron nail after connecting the battery to the wire, the iron nail would behave like a magnet by attracting the pieces of iron because they are oppositely charged.

         A quantum is the smallest discrete unit of a phenomenon (plural: quanta). For instance, a photon is a quantum of light, while an electron is a quantum of electricity. Quantum is a Latin word that means "quantity" or "how much?" Anything that can be measured is something that can be quantified.

             Bohr's hypothesis, often known as quantum theory, postulated that electrons move around the nucleus according to the classical principles, but with restrictions on the orbits they can take and the energy they lose as radiation when they change orbits.

        The Bohr model, also known as the Rutherford-Bohr model, was first proposed by Niels Bohr and Ernest Rutherford in 1913 and describes an atomic system with an orbiting system of electrons and a small, dense nucleus that is similar to the Solar System in structure but is attracted by electrostatic forces rather than gravity.

           A small positively charged nucleus is encircled by rotating negatively charged electrons in set orbits, according to the Bohr Atomic Model. He came to the conclusion that an electron will have more energy if it is placed far from the nucleus and less energy if it is located close to the nucleus.
