Answer:
1
Explanation:
The equation is already balanced, and on the left hand side (reactants side), we see that there's one CH4 molecule and 2 O2 molecules. We don't care about the O2 molecules in this case, so we turn our focus to the CH4 molecule. One CH4 molecule has one carbon atom and 4 H atoms, so we know that there's only one carbon atom on the reactants side.
Answer:
1. Vacuole
2. chloroplast
3. Nucleus
4. Plasma membrane - cell membrane
5. Vacuole (same as #1 ?) could be vesicle
Explanation:
Answer:
771.15g of TiCl4
Explanation:
460 grams of sodium=20 mol
equation of the reaction is TiCl4+4NA=4NaCl+Ti
1 mol of titanium chlroide reacts with 4. that means there are 5 mols of titanium chloride
titanium chloride has a molar mass of 154.23 g.
mutiply that by 5 and we have 771.15 g
Answer:
The answer is 0, 506 mol
Explanation:
We calculate the weight of 1 mol of NaCl:
Weight 1 mol NaCl = Weight Na + Weight Cl= 23 g + 35, 5 g = 58, 5 g
58, 5 g----1 mol NaCl
29, 6 g----x= (29,6g x 1 mol NaCl)/ 58,5 g = 0,505982906 mol NaCl
