Explanation:
Hello!
In this case, since the reaction between sulfur and oxygen is:
Whereas there is a 1/2:8 mole ratio between oxygen and SO3, and we can compute the produced grams of product as shown below:
Best regards!
Answer:
Fatty acids have an even number of carbons because they are synthesized from a starting material (acetyl-CoACoA) that has an even number of carbons.
Explanation:
Fatty acids are carboxylic acids and are known to have even number of carbon atoms because they are synthesized from a 2 carbon atom acetyl Co-A molecules which are assembled together. It contains a carboxylate group covalently joined with an hydrophobic head of CH3-(CH2)n and may have an unsatireated CH=CH group within its CH2 chain. The synthesis of fatty acids from acetyly Co-A involves the activation reaction of an enzyme acetyl Co-A synthetase with an acid. It involves dehydrogebation, hydration, oxidation and thiolysis. Fatty acids vary in length of its chain, the number of carbon-carbon double bonds attached to its CH2 chain nd also the location of those double bonds in the carbon chain. Saturated fatty acids are those without carbon-carbon double bond in its chain while unsaturated have carbon- carbon double bonds. Monounsaturated fatty acids have one carbon-carbon double bonds and polyunsaturated fatty acids have two or more carbon-carbon double bonds.
Answer:
1.Some smokeless tobacco products might expose people to lower levels of harmful chemicals than tobacco smoke, but that doesn’t mean these products are a safe alternative to smoking.
2.Tobacco smoke is made up of thousands of chemicals, including at least 70 known to cause cancer. These cancer-causing chemicals are referred to as carcinogens. Some of the chemicals found in tobacco smoke include.

Given parameters:
Equation of the reaction 2PbS + 30₂ → 2PbO + 2SO₂
Number of moles of 0₂ = 0.6moles
Unknown:
Mass of PbO produced = ?
Solution:
The number of moles is the quantity used in chemistry to express the amount of particles contained in a substance.
2PbS + 30₂ → 2PbO + 2SO₂
From the reaction;
3 moles of O₂ will produce 2 moles of PbO
0.6 moles of O₂ will then produce = 0.4moles
Now since the we know the number of moles of PbO;
Mass of PbO = number of moles of PbO x molar mass
molar mass of PbO = 207.2 + 16 = 223.2g/mol
Mass of PbO = 0.6 x 223.2 = 133.92g

<u>Answer</u>
79 ml
<u>Explanation</u>
You have 237 237 ml of ammonia, whose strength is 100%.
If you want to make it 75%, then;
let 75% ⇒ 237 ml of ammonia and
25% ⇒ x ml of water.
∴ x = (25% ×237) / 75%
= 5,925/75
= 79 ml of water.
