The substance is a liquid. Think about water :)
Answer:
H₂O (water)
Explanation:
The reaction given is the glucose combustion inside the cells. During the combustion, it will be formed carbonic gas, water and energy.
The oxygen molecule is split in their two atoms of O. The element which has 1 proton and 1 electron is the hydrogen (H). So, when hydrogen reacts with oxygen, they form water (H₂O).
Cl is stable as a diatomic molecule where the 2 Cl atoms are held together by a covalent bond
molar mass of the diatomic molecule is 70.9 g/mol
therefore 70.9 g of Cl₂ is - 1 mol
then 140 g of Cl₂ is - 1/70.9 x 140 = 1.97 mol
there are 1.97 mol of Cl₂ present

hope it helps! sorry for no explanation
Since the equation is balanced we can use the molar ratios to jump between amounts of substances.
CH4 + 2O2 ---> CO2 + 2 H2O
1.You can use a molar ratio to convert between mols methane to mols CO2:
4.70×10−3 mol CH4 X (1 CO2 / 1 CH4) = 4.7x10^-3 mol CO2 X (44g/1mol) = .2068g CO2
2. You can do the same technique with the water.
4.70×10−3 mol CH4 X (2 H2O / 1 CH4) = .0094 mol H2O X (18g/1mol) = .1692g H2O
3. You can do the same technique with the O2.
4.70×10−3 mol CH4 X (2 O2 / 1 CH4) = .0094 mol O2 X (32g/1mol) = .3008g O2
