Answer;

The balanced equation will be;

2C4H10 + 13O2 -> 8CO2 + 10H2O

Explanation;

-According to the law of conservation of mass , in each chemical equation the mass should be conserved, therefore the number of atoms of each element should be equal on the side of reactants and that of products, this is done by balancing the chemical equation.

-Therefore, to balance the above chemical equation, we will put a coefficient of 2 on C4H10, a coefficient of 13 on O2, a coefficient of 8 on CO2 and a coefficient of 10 on H2O. By so doing the equation will be balanced since the number of atoms of each element are equal on either side. We obtain;

2C4H10 + 13O2 -> 8CO2 + 10H2O

Atomic oxygen would most likely form its most stable monatomic ion when it: 1. elevates one electron from the s orbital to a p o

sineoko [7]

Answer:

5. gains two electrons.

Explanation:

In order to determine the most stable monoatomic ion of oxygen, we need to consider the octet rule: atoms will gain, lose or share electrons to complete their valence shell with 8 electrons.

Oxygen is in the Group 16 in the Periodic Table, so it has 6 valence electrons. Therefore, it will gain two electrons to have the electron configuration of the closest noble gas.

How many liters of CO2 are in 4.76 moles? (at STP)

dem82 [27]

Answer: The volume of carbon dioxide gas at STP for given amount is 106.624 L

Explanation:

We are given:

Moles of carbon dioxide = 4.76 moles

At STP:

1 mole of a gas occupies a volume of 22.4 Liters

So, for 4.76 moles of carbon dioxide gas will occupy a volume of = $\frac{22.4L}{1mol\times 4.76mol=106.624L$

Hence, the volume of carbon dioxide gas at STP for given amount is 106.624 L

Consider this chemical reaction. What chemical is reduced? CH3OH + NAD --> CH2O + NADH

nikklg [1K]

Answer:

CH3OH and NADH

Explanation:

The given chemical reaction is an redox reaction in which reduction and oxidation take place.

In the process of oxidation: electrons are loss while in the process of reduction: electrons are gained.

In the given redox reaction: CH3OH + NAD --> CH2O + NADH

NAD is reduced to NADH as NADH gains one hydrogen electron while CH3OH (methanol) is oxidized to CH2O (methanal) by losing electrons.

So, CH3OH (methanol) and NADH are the reduced forms while NAD and CH2O (methanal) are oxidized forms.

A sample of a pure compound that weighs 60.3 g contains 20.7 g Sb (antimony) and 39.6 g F (fluorine). What is the percent compos

Volgvan

Answer:

The percent composition of fluorine is 65.67%

Explanation:

Percent Composition is a measure of the amount of mass an element occupies in a compound. It is measured in percentage of mass.

That is, the percentage composition is the percentage by mass of each of the elements present in a compound.

The calculation of the percentage composition of an element is made by:

$percent composition element A=\frac{total mass of element A}{mass of compound} *100$

In this case, the percent composition of fluorine is:

$percent composition of fluorine=\frac{39.6 g}{60.3 g} *100$

percent composition of fluorine= 65.67%

The percent composition of fluorine is 65.67%
