Answers
Answer:
1.0001 M
Explanation:
Molarity = Mass/(Volume x molar mass)
Molarity = 98.0 g/(1.00 L x 97.994 g/mol)
Molarity = 1.0001 M
the molarity of 98.0 g of phosphoric acid, H3PO4 in 1.00 L of solution is 1.0001 M
what is the difference between molarity and molality ?Molarity can be defined as the number of moles of solute available in a definite concentration and amount of the solution, other wise called as moles per liters of a solution.
Molality of a solution can be defined as the number of moles per solute can be present in a kilogram of the solvent, which is moles per kilogram of a solvent.
Though the terms Molarity and Molality are quite similar but the sharp difference between them as it creates a huge difference while using this two form of calculation for various calculations.
Molarity = Mass/(Volume x molar mass)
Here, Molarity = 98.0 g/(1.00 L x 97.994 g/mol)
Molarity = 1.0001 M

C2H4(g) + 3O2(g) 2CO2(g) + 2H2O(g)
The volume of one mole of gas at STP is 22.4 liters.
Answers
1 • (22.4L / 270L) = 3 • (22.4L / x)
1/270L = 3/x
x = 3(270) / 1
x = 810 L
810 Liters of oxygen will react with 270 liters of ethene (C2H4) at STP

3. Explain the difference between a chemical equation and a nuclear equation.
4. What is the relationship between the atomic number and the mass number of a 5. nucleus?
Please help me understand these!! I'm really confused!
Answers
Answer:
Transmutation is the conversion of an atom of one element into an atom of a different element through nuclear changes.
An alpha particle is a particle composed of 2 protons and 3 neutrons. It results from transmutation because of the change in protons in a large nucleus.
A chemical equation is balanced accord to the number of atoms of each element before and after the change. This is also shows the Law of Conservation of Matter.
A nuclear equation is balanced according to mass number and charge (atomic number). These equations can’t be balanced like chemical equations because the identities of the atoms can change. On the left of equation, the top number is the atomic mass and the bottom number is the atomic number. Take note that if you add the atomic mass (top number), you’ll get the the atomic mass of of the atom pre-transmutation. Same applies with atomic number. This shows a balanced nuclear equation.
The atomic number is the number of protons in a nucleus. The mass number is the sum of the protons and neutrons in a nucleus. Electrons have very small masses, so they are not accounted in atomic mass.

A volume of 10.0 mL of 25 mg/L Mn2+ solution was diluted to make a solution with the final volume of 50.0 mL. Calculate the concentration (in mg/L) of the final solution
Answers
Taking into account the definition of dilution, the concentration of the final solution is 5 mg/L.
First of all, you have to know that dilution is the reduction in concentration of a chemical in a solution. The process consists of adding more solvent to the same amount of solute.
In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases.
A dilution is mathematically expressed as:
Ci×Vi = Cf×Vf
where
Ci: initial concentration Vi: initial volume Cf: final concentration Vf: final volumeIn this case, you know:
Ci= 25 mg/L Vi= 10 mL Cf= ? Vf= 50 mLReplacing in the definition of dilution:
25 mg/L × 10 mL= Cf × 50 mL
Solving:
Cf= (25 mg/L × 10 mL)÷ 50 mL
Cf= 5 mg/L
In summary, the concentration of the final solution is 5 mg/L.

Answer:
pour the rock salt mixture throught a filter made from paper and allow the liquid to filtrate .
Explanation:
Separating Sand and Salt
Probably the easiest method to separate the two substances is to dissolve salt in water, pour the liquid away from the sand, and then evaporate the water to recover the salt.
Pour the liquid through a paper filter made of rock salt mixture and let it filter, after complete filtration we obtain crystals of salt.
What is filtration?Filtration is defined as the technique of removing solid particles from a liquid or gaseous fluid by passing the fluid through a filter media while keeping the solid particles behind.
It can also be defined as a physical method that uses a filter media with a complicated structure that only allows fluid to pass through to separate solid matter and liquid from a combination.
There are six types of filtration.
Vacuum filtrationCentrifugal filtrationGravity filtrationCold filtrationHot filtrationMultilayer filtrationMixture is defined as a substance that is composed of two more chemical compounds or substances that do not chemically mix.
There are two types of mixture.
Homogenous mixtureHeterogenous mixtureThus, pour the liquid through a paper filter made of rock salt mixture and let it filter, after complete filtration we obtain crystals of salt.

Answers
Tin has electron configuration [Kr] 5s²4d¹⁰5p² and it is not a transition element because its outermost orbitals are 5s² 5p². It has oxidation states of +2 and +4.
The electron configuration of tin is [Kr] 5s²4d¹⁰5p². The electronic structure of an atom shows the arrangement of electrons in the atom of an element. The electrons are arranged in sub-shells.
Tin is not a transition metal because it has a completely filled d sub-shell and its outermost shell consists of ns, np orbitals.
Tin looses its electrons in pairs. Remember that the outermost orbitals are 5s² 5p². This means that tin can have two stable oxidation states, +2 and +4.
