<u>Given:</u>
Moles of CS2 (it cannot be CO2 as mentioned in the question, since O2 reacts with CS2 and not CO2) = 34.5 mol
<u>To determine:</u>
Moles of O2 undergoing the reaction
<u>Explanation:</u>
The reaction is-
CS2 + 3O2 → CO2 + 2SO2
Based on the stoichiometry: 3 moles of O2 reacts with 1 mole of CS2
therefore the moles of O2 that would combine with 34.5 moles of CS2 are
= 3 moles O2 * 34.5 moles CS2/1 mole CS2 = 103.5 moles
Ans: Around 104 moles of O2 would react with 34.5 moles of CS2
Answer:
2.8g/cm³
Explanation:
Given parameters:
Mass of cube = 42g
Volume of cube = 15cm³
Unknown:
Density of the cube = ?
Solution:
Density is defined as the mass per unit volume of a substance. It is mathematically expressed as:
Density =
So;
Density =
= 2.8g/cm³
Answer:
True
Explanation:
All the chemical elements have their abbreviations as one or two letters
The first letter in the abbreviation is a capital letter and the second letter is always a small letter
Majority of abbreviations are based on their english names
Answer:see attached image
Explanation:
In organic chemistry, a product may be kinetically or thermodynamically favoured. A kinetically favours product forms faster, it may not necessarily be the more stable product. The thermodynamically favoured product forms at a slower rate but is more stable. Often times, the kinetically favoured product rearranges itself to form the thermodynamically favoured product at equilibrium. The endo product of the Diels Alder reaction mentioned in the question is first formed (kinetically favoured) but rearranges to form the exo product (thermodynamically favoured) at equilibrium. This is clear shown in the reaction mechanism attached below.
Answer:
No
Explanation:
If you added the reactants on the reactant side because there is one atom for nitrogen on the product side while there is two atoms on the product side. There are more hydrogen products on the reactant side as well.
