1) The equation is already balanced;
Left side: 1C, 2H and 1O
Right side: 1C, 1O, 2H
2) Starting substances: water and carbon
There are two starting substances also called reactants. H2O which is a compound and C which is an element.
3) Ending substance asked for: H2.
This is hydrogen gas.
Stoichiometry:
1 mol of C produces 1 mol of H2
12.01 g of C productes 2.016 grams of H2
Ratio: 2.016 g of H2 / 12.01 g of C = X g of H2 / 34 g of C =>
x = 34 g of C* 2.016 g of H2 / 12.01 g of C= 5.707 g of H2
Answer:
180º
Explanation:
Carbon has 4 valence electrons and to complete the octet requires 4 more , so it will share with the oxigen atoms 4 more, forming a single and a pi bond similar to CO2
Since the carbon does not have lone pairs, the geometry around this central atom will be linear and the angle will be 180 , S = C = S
Answer:
Refer to the period table. Use the atomic mass for calculation. Multiply the atomic mass with the number of atoms. For example, Al2(SO4)3. (27 × 2) + (32 x 3) + (16 x 12) = molecular mass
Answer:
The amount of solute added.
Explanation:
The amount of solute added is directly proportional to the number of ions.
The higher the amount added the higher the number of moles.
The number of moles is multiplied by the Avogadro's constant to get the number ions.
No of ions= No of moles × L
L is the Avogadro's number.
