Answer:
1368 grams
Explanation:
Molar Mass of malt sugar (C12H22O11) = 342 g
Molarity= 342 g/ mol
so 1 molar solution contain = 342 g /Liter
4 Molar solution contain= 1368g / Liter
Kcal=1000 cal
Min=60 sec
0.74 *1000= 740cal/min
740 cal/min /60= 12.333 cal/s
1, 4, 1, 2, 1
Explanation:
We have the following chemical reaction:
MnO₂ + HCl → MnCl₂ + H₂O + Cl₂
To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each element leaving the reaction, in order to conserve the mass.
So the balanced chemical equation is:
MnO₂ + 4 HCl → MnCl₂ + 2 H₂O + Cl₂
