0.912 mol Na2CO3 × 105.9888g Na2CO3/ 1 mol Na2CO3 = 96.66 grams
Answer:
Repulsive forces exist only when atoms are very close to each other. (3/14) "They [the atoms] will approach until both nuclei will simply shove each other because both of them are positive." The balance between the attraction and repulsion forces determines how close the atoms can get. The relationships between the magnitude and direction of repulsive and attractive forces. A stable state of a bond is when attractive forces balance repulsion forces. “A stable state between two atoms is when they attract each other with a force that equals the force that they repel each other.”
If the reaction started with 32g of Sulfur and 56 grams of Iron, then mass of produced FeS is 88 grams.
<h3>What is the relation between mass & moles?</h3>
Relation between the mass and moles of any substance will be represented as:
n = W/M, where
- W = given mass
- M = molar mass
Moles of Fe = 56g / 56g/mol = 1 mol
Moles of S = 32g / 32g/mol = 1 mol
Given chemical reaction is:
Fe + S → FeS
From the stoichiometry of the reaction same moles of iron and sulfur are required to produce equal moles of iron sulfide. Means 1 mole of iron produces 1 moles of iron sulfide and mass of iron sulfide will be calculated as:
W = (1mol)(88g/mol) = 88g
Hence required mass of iron sulfide is 88 grams.

Answer:
The turnover number is the maximum substrate quantitiy converted to product per enzyme and per second. It can be calculate as follows:
with active enzyme concentration.
In this case we have Vmax an data to calculate
Now
it is not like any option.
If we assume that have the non usual units of and it is
So we need divide by the moles of E (in place of [E])
Now
(pass from to dividing by 60)
