Hello!
First you have to find the molar mass of the molecules
C = 12
O = 16
2Cl = 71
6H2O = 108
Add them up to find the total molar mass
12 + 16 + 71 + 108 = 207g/mol
Divide the amount of water by the total molar mass
108 / 207 = 0.5217
Convert this to a decimal
0.5217 = 52.17%
The answer is 52.17%
Hope this helps!

The most efficient way to determine whether a reaction is an exothermic chemical
reaction is to use —
A) an oxygen probe
B) a temperature probe
C) a pressure probe
D) a pH probe
...............................................................................................................
Answer:
Reaction is said to be exothermic in nature, if heat is evolved from the system. The resultant product formed is more stable. Since, during exothermic reaction, heat is given out be the system, temperature of system will increase. Hence, temperature is the probe to determine exothermic reaction.
Thus, correct answer is option B) a temperature probe
Answer:The best answer is D. breakdown of rock through mechanical or chemical processes
Explanation:
Answer:
36 atoms
Explanation:
- C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy
The reactants are in the left side of the equation. <u>First we determine how many atoms are there in the C₆H₁₂O₆ molecule</u>:
- 6 C atoms + 12 H atoms + 6 O atoms = 24 atoms in total
There are two atoms in a O₂ molecule, and there are 6 O₂ molecules in the equation:
- 2 * (6 O atoms) = 12 atoms in total
The total number of atoms in the reactants is
