Answer:
12 carbon, 22 hydrogen, 11 oxygen
Explanation:
Our equation is: Sugar + 
⇒ 
+ 
This is already balanced which means that the number of atoms for each type of element on each side should be the same.
On the right side, there are 11 * 2 = 22 hydrogen atoms, 11 * 1 + 12 * 2 = 11 + 24 = 35 oxygen atoms, and 12 * 1 = 12 carbon atoms.
Currently on the left, there are 12 * 2 = 24 oxygen atoms. That means that sugar must have 11 oxygen atoms to balance it out. In addition, since the left side currently has no hydrogen or carbon atoms, those must belong to the sugar molecule.
Thus, the sugar molecule has 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms.
Answer:
So X has an atomic mass of 55.05 u, and is probably Mn
Explanation:
<u>Step1: </u>Balance the equation
XI2 +Cl2 → XCl2 + I2
<u>Step2:</u> find the molar mass of the compounds
<em><u>Compounds : </u></em>
X ⇒ Molar mass = M
XI2 ⇒ Molar mass = M + 2*126.9 u
XCl2 ⇒Molar mass = M + 2*35.45u
⇒For 1 mole XI2 we have 1 mole Cl2 reacting , as well as 1 mole XCl2 and 1 mole I2 produced.
<u>Step 3:</u> Calculating the atomic mass
(1.383g * XI2) / (M + 2*126.90 u) = (0.564g * XCl2) / ( M + 2 * 35.45u)
1.383 (M + 2 *35.45 u )= 0.564 (M + 2*126.90)
1.383M + 98.0547 = 0.564 M + 143.1432
1.383 M - 0.564 M =143.1432 - 98.0547
0.819 M = 45.0885
M = 55.05 u
So X has an atomic mass of 55.05 u ⇒ if we look at the periodic table we can find that the closest element is Manganese (Mn)
MnI2 + Cl2 → MnCl2 + I2
Answer:
Yes.
Explanation:
Mold is a living organism. All living organisms are made up of cells.
I believe it would be 7.731. x 10^5? That is if they want you to evaluate.
