CO2 + H2 -> CO + H2O What is being oxidized?

Answers

Answer 1

Answer:

Hydrogen is being oxidized in the given reaction CO2 + H2 → CO + H2O. the carbon atom in CO2 is reduced to CO, while the hydrogen atoms in H2 are oxidized to H2O.

How is that so?

Oxidation is the loss of electrons, while reduction is the gain of electrons. To determine which class is being oxidized and that is being diminished, we can equate the oxidation states of the materials in the reactants and produce.

In CO2, the element atom has an oxidation state of +4, while the oxygen atoms each have an disintegration state of -2. In H2, each hydrogen atom has an decay state of 0.

In CO, the element atom has an oxidation state of +2, while the oxygen dot in H2O has an oxidation state of -2. The hydrogen atoms in H2O each have an disintegration state of +1.

Therefore, the carbon atom in CO2 is decreased to CO, while the hydrogen atoms in H2 are oxidized to H2O.

What is the gram formula mass of Ca3(PO4)2

Answers

Mass Molar of $Ca_(3) (PO_4)_2$
Ca = 3*40 = 120 amu
P = 2*31= 62 amu
O = (16*4)*2 = 64*2 = 128 amu
--------------------------------------
Mass Molar of $Ca_(3) (PO_4)_2$ = 120 + 62 + 128 = 310 g/mol

Therefore: What is the gram formula mass of Ca3(PO4)2 ?

Consider the reaction below. 2Al2O3 mc019-1.jpg 4Al + 3O2 How many moles of oxygen are produced if 11.0 mol of Al are produced?

Answers

Answer: 8.25 moles of oxygen are produced.

Explanation: The reaction follows:

$2Al_2O_3(s)\rightarrow 4Al(s)+3O_2(g)$

By Stoichiometry,

As, 4 moles of Aluminium is produced by 2 moles of aluminium oxide

11 moles of aluminium will be produced by = $(2)/(4)* 11=5.5moles$

Now, 2 moles of aluminium oxide produces 3 moles of oxygen, so

5.5 moles of Aluminium oxide will produce = $(3)/(2)* 5.5=8.25moles$

Hence, 8.25 moles of oxygen will be produced.

2 Al₂O₃ = 4 Al + 3 O₂

4 moles Al ----------> 3 moles O₂
11.0 moles Al -------> ?

O₂ = 11.0 * 3 / 4

= 8.25 moles of O₂

A carbon-12 atom has a mass of 12.00000 amu. The mass of a proton is 1.00728 amu, and the mass of a neutron is 1.00866 amu. How many protons does the carbon-12 atom have? How many neutrons does the carbon-12 atom have? What is the mass defect of a carbon-12 atom? amu

Answers

A carbon - 12 atom and a regular carbon atom would have the same number of protons which is 6. So a carbon - 12 atom would have 6 protons. Both, however, would differ in the number of neutrons. Carbon - 12 atom has 6 neutrons. To determine the mass defect of a carbon - 12 atom, we have to add the total mass of protons and the total mass of neutrons and subtract the known mass of a carbon - 12 atom. That would be like this.
6 (1.00728 amu) + 6 (1.00866 amu) = x
6.04368 amu + 6.05196 amu = x
12.09564 amu = x

Then subtract it with 12 amu to get the defect mass

12.09564 amu - 12.00000 amu = y
0.09564 amu = y

So the defect mass would be 0.09564 amu.

1) The number of protons in an element defines its atomic number, and for carbon, it is 6. 2) Number of neutrons in a carbon-12 atom is 6. 3) The mass defect of a carbon-12 atom is 0.09564 amu.

To determine the number of protons and neutrons in a carbon-12 atom and the mass defect, we need to use the given atomic masses of a proton and a neutron.

Number of protons in a carbon-12 atom:

Carbon-12 is the most common isotope of carbon, and it contains 6 protons. The number of protons in an element defines its atomic number, and for carbon, it is 6.

Number of neutrons in a carbon-12 atom:

The mass number of an isotope will be the sum of protons as well as neutrons in its nucleus. For carbon-12, the mass number is 12 amu. Since we already know it has 6 protons, the number of neutrons can be calculated as follows:

Number of neutrons = Mass number-Number of protons

Number of neutrons = 12 amu-6 protons

Number of neutrons = 6 neutrons

Mass defect of a carbon-12 atom:

The mass defect is the difference between the actual mass of a nucleus and the sum of the masses of its individual protons and neutrons.

Mass defect = (Mass of protons + Mass of neutrons) - Actual mass of carbon-12

Mass of protons = 6 protons × 1.00728 amu/proton = 6.04368 amu

Mass of neutrons = 6 neutrons × 1.00866 amu/neutron = 6.05196 amu

Actual mass of carbon-12 = 12.00000 amu

Mass defect = (6.04368 amu + 6.05196 amu) - 12.00000 amu

Mass defect = 12.09564 amu - 12.00000 amu

Mass defect = 0.09564 amu

So, the mass defect of a carbon-12 atom is 0.09564 amu.

How would an electron shell model of an oxygen atom (O) appear after the atom has formed chemical bonds?a. It would have six electrons in the outermost shell.
b. It would have six electrons in the innermost shell.
c. It would have eight electrons in the outermost shell.
d. It would have eight electrons in the innermost shell.

Answers

oxygen atomic number is 8.

electron configuration of O is 2,6

therefore O has 6 valence electrons. valence electrons are electrons in the outermost shell that are involved in chemical bonds

atoms to become stable should fulfill the octet rule. This is where the outermost shell should have 8 electrons

so atoms with incompletely filled outer shells take part in chemical bonds to gain a complete octet and to become stable

So O too after forming a chemical bond would have 8 electrons in the outermost shell.

correct answer is

c. It would have eight electrons in the outermost shell.
