PLEASE HELP ASAP!! CHEMISTRY BALANCING EQUATIONS!

Chemistry
1 answer:
sergejj [24]3 years ago

Answer:

B. 2.12 L  

Step-by-step explanation:

We know we will need a balanced chemical equation with masses and molar masses, so, let's gather all the information in one place.

M_r:                   32.00

        4NH₃(g) + 7O₂(g) ⟶ 4NO₂ + 6H₂O(g)

m/g:                      5.3

(a) Moles of O₂

Moles of O₂ = 5.3 × 1/32.00

Moles of O₂ =0.166 mol

=====

(b) Moles of NH₃

The molar ratio is 4 mol NH₃= 7 mol O₂.

Moles of NH₃ = 0.166 × 4/7

Moles of NH₃ = 0.0946 mol NH₃

=====

(c) Volume of NH₃ at STP

STP is 1 bar and 0 °C. At STP, the molar volume of a gas is 22.71 L.

Volume of NH₃ = 0.0946 ×22.71/1

Volume of NH₃ = 2.15 L

=====

It looks as if you are using the <em>old</em> (pre-1982) definition of STP.

Under that definition, the molar volume of a gas at STP was 22.41 L.

The volume of NH₃ is then <em>2.12 L</em>.

What is the average dose of radiation that most people are exposed to every year not including dental or medical personnel deali
andriy [413]

C. The average dose of radiation that most people are exposed to every year not including dental or medical personnel dealing with X-rays is 2400 u Sv.

<h3>What is x-ray?</h3>

X-rays are a form of electromagnetic radiation, similar to visible light used for medical treatment and other forms of x ray inspection.

An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation.

The average dose of radiation that most people are exposed to every year not including dental or medical personnel dealing with X-rays is 2400 u Sv or 2.4 m u Sv.

Thus, the average dose of radiation that most people are exposed to every year not including dental or medical personnel dealing with X-rays is 2400 u Sv.

Wood is made mostly of cellulose and has a chemical formula of C6H1005. Which of
astra-53 [7]

Answer:

Answer below

Explanation:

First to show combustion, you use O₂.

So   C₆H₁₀O₅ +  O₂ is the reaction.  Assuming complete combustion, all you get as products are CO₂ and H₂O.  Then you have to balance the full reaction.

C₆H₁₀O₅  +  6O₂  ----->  6CO₂  +  5H₂O

6 Carbons on each side

10 Hydrogens on each side

17 Oxygens on each side

What is the correct iupac name of CH3-CH2-CH2CHO ?
kow [346]

the correct IUPAC name of the compound is 1-Butanal.

<h3>What are IUPAC names?</h3>

It is a system of naming organic compounds based on the longest carbon-to-carbon single bonds. It does not matter whether these longest chains are continuous or in a ring.

Thus, when the compound with the chemical formula, CH3-CH2-CH2CHO is considered. The longest carbon-to-carbon chain is 4. The 1st carbon carries a functional group known as an aldehyde.

Aldehydes are equipped with the carbonyl group and have the general formula R−CH=O. They are also sometimes referred to as formyl.

Aldehydes are named after their parent alkane chains with a slight modification. The 'e' is replaced with 'al'

The aldehyde in this case has four carbons. This means that the parent alkane is Butane. Therefore, the name of the compound will be 1-Butanal.
