Answer:
The rate at which sulfur dioxide is being produced is 0.90 kg/s.
Explanation:
Volume of oxygen gas consumed in second ,V= 994 L
Pressure of the gas = p
Temperature of the gas = T = 170°C= 170 + 273 K=443 K
Moles of oxygen gas consumed in a second = n
( ideapl gas equation)
n = 21.044 mole
Moles of dioxygen gas consumed per second = 21.044 mol
(Claus process)
According to reaction, 3 moles of dioxygen gives 2 moles of sulfur dioxide gas.Then 21.044 moles of dioxygen will give;
of sulfur dioxide
Mass of 14.029 moles of sulfur dioxide gas;
14.029 mol × 64 g/mol = 897.86 g
897.86 g = 0.89786 kg ≈ 0.90 kg
Mass of sulfur dioxide produced per second = 0.90 kg
The rate at which sulfur dioxide is being produced is 0.90 kg/s.
Answer:
true
Explanation:
light travels faster than sound.
Answer:
slower
Explanation:
NBS is used in place of Br2 during bromination because the use of Br2 tends to result in the formation of a large concentration of the addition product. This is because, the Br2 interacts with the double bond to yield only the dibromide (addition product).
The usefulness of NBS lies in the fact that it provides a lower concentration of Br2, and such that the rate addition is slower than the chain propagation steps. Only the monobromination product is observed
The low concentration of Br2 allows the free-radical reaction to out-compete the alkene addition reaction.
they move tightky compacted and slower or not at all i belive not 100% sure though
We know that the electron clouds of two atoms overlapping is a bond, because that signifies that the electrons are being shared in a bond.
So, I'm going to go through some definitions of these different types of bonds, because they have very specific circumstances.
<u>A hydrogen bond is a bond between an electronegative atom and a hydrogen molecule</u> (which is not what this question says, this isn't stated anywhere).
<u>A dipole is a difference in electron density on two different atoms</u> (so this isn't even close to what the question is stating, a dipole is not even a bond)
<u>An ionic bond is an </u><u><em>unequal sharing of electrons</em></u><u> between two atoms </u>(because the question doesn't state this specific fact, then it can't be this option).
By process of elimination, we know the answer is covalent bond, but just in case, we can also look at the definition of a covalent bond: <u>a bond that involves the sharing of electrons between atoms.</u>
That is exactly what the question is asking for! Therefore, your answer is d. covalent bond
