Given the following equation: 2C6H6 + 1502 - 12CO2 + 6H20
How many moles of O2 are needed to react with 4.0 moles of
Co HG?
a 30 moles
b 12 moles
C 4.0 moles
d 24 moles

Answers

Answer 1

Answer:

a) 30 moles

Explanation:

                           2C6H6 + 1502 -------> 12CO2 + 6H20

from reaction      2 mol       15 mol

given                    4.0 mol     x mol

x = 4.0*15/2 = 30. mol

Answers

Answer:

0.17166666666

Explanation:

Answer:

New volume V2 = 1.7625 L

Explanation:

Given:

Old temperature T1 = 27°C = 27 + 273 = 300 K

Old volume V1 = 1.25 L

New temperature T2 = 150°C = 150 + 273 = 423 K

Find:

New volume V2

Computation:

V1 / T1 = V2 / T2

1.25 / 300 = V2 / 423

New volume V2 = 1.7625 L

A molecule is

A a group of atoms bonded by ionic bonds.
B a group of atoms bonded by covalent bonds.
C a group of ions bonded by covalent bonds.
D a group of atoms bonded by metallic bonds.

Answers

Answer:

B.

Explanation:

Atoms make up molecules and ionic bonds cannot make up a molecule because they do not share electrons like in a covalent bond.

Which of the following statements BEST describes a mixture?
А
Carbon dioxide is an example of a heterogeneous mixture.
B
A compound and a mixture are the same type of substance.
Two elements that are in the area but not chemically combined can be a mixture.
D
A mixture is unable to be separated because the molecules have been chemically combined.

Answers

Answer: C) Two elements that are in the area but not chemically combined can be a mixture

==============================================================

Explanation:

An example of a mixture would be salt and water. The salt particles dissolve into the water but no chemical change has happened. I mean that no new chemical compound is made and also heat/energy is not given off. Furthermore, we can separate the two items (for instance through evaporation) and those two items retain their original properties. This helps show that the salt and water particles don't form a bond and we can separate those particles apart so to speak.

Another example of a mixture is iron and plastic. We can pull out the iron through using a strong magnet. Whether or not the iron is with the plastic, the iron retains its properties. The same can be said of the plastic. The two materials just happen to occupy the same space or volume or area.

If you have two chemicals react in some way to form a new chemical, then this is not a mixture. For instance if we combine vinegar and baking soda, it produces carbon dioxide and water. There isn't a process to undo this to get the vinegar and baking soda back (like there was a process to get the iron separated).

Answers

Answer:

5SiO2 + 2CaC2 ➡ 5Si + 2CaO + 4CO2

Explanation:

This question involves balancing the above equation. An equation is said to be BALANCED when all the atoms of each element in the reactant side equates that in the product side.

According to this question, a chemical reaction is given as follows: SiO2 + CaC2 = Si + CaO + CO2. Based on observation, the atoms of elements are Silicon, oxygen, calcium and carbon are not the same on the reactants and products side. Based on this, the balanced equation is:

5SiO2 + 2CaC2 ➡ 5Si + 2CaO + 4CO2

A brand of soda has one of the highest quantities of sugar among popular soda drink packing 52 grams into each 12 oz can how many molecules of sugar are in one can of this soda

Answers

Answer:

9.0 × 10²² molecules of sugar (sucrose)

Explanation:

Step 1: Given and required data

Mass of sugar in each can of soda (m): 52 gMolecular formula of sugar (sucrose): C₁₂H₂₂O₁₁Molar mass of sucrose (M): 342.3 g/mol

Step 2: Calculate the moles of sugar (n) in each can

We will use the following expression.

n = m/M = 52 g / (342.3 g/mol) = 0.15 mol

Step 3: Calculate the molecules corresponding to 0.15 moles of sugar

We will use Avogadro's number: there are 6.02 × 10²³ molecules in 1 mole of molecules.

0.15 mol × 6.02 × 10²³ molecules/1 mol = 9.0 × 10²² molecules

Why do the atoms in a piece of copper metal have no net charge?


1.The charges of the positive and negative copper ions cancel each other out.

2.The number of electrons surrounding each copper nucleus doesn’t change.

3.Copper atoms can’t lose electrons without a substance present to gain electrons.

4.When a copper atom loses electrons, it also loses a corresponding number of protons.

5.The copper atoms exchange neutrons instead of electrons.

Answers

Answer:

The correct answer is the charges of the positive and negative copper ions cancel each other out.

Explanation:

A copper metal having no net charge means that it is a neutral atom. A neutral atom means that total number of protons is equal to the total number of electrons.

Northwood Company manufactures basketballs.The company has a ball that sells for $25.At present, the ball is manufactured in a small plant that relies heavily on direct labor workers.Thus, variable expenses are high, totaling 15% per ball, of which 60 percent is direct labor cost.Last year, the company sold 30,000 of these balls, with the following results:Sales $750,000Variable expenses (450,000)Contribution margin 300,000Fixed expenses (210,000)Net operating income$ 90,0001.
