Answer: nvm i do not know the answer to this i thought i did but i dont
Explanation: sorry about that
We calculate for the number of moles of water given its mass by dividing the given mass by the molar mass.
n water = (36.04 g) / (18 g/mol)
n water = 2 mols
From the given balanced equation, every 6 moles of water produced will require 7 moles of oxygen.
n oxygen = (2 mols H2O) x (7 moles O2 / 6 moles H2O)
n oxygen = 2.33 mols O2
Answer:
Maple syrup will have the higher temperature.
Explanation:
- Adding CaCl₂ to water and maple syrup will rise the temperature of both of them.
Specific heat of maple syrup = 2.01 J/g.°C
.
Specific heat of water = 4.18 J/g.°C.
- Which means that the energy needed to rise the temperature by 1.0 °C of 1.0 g of water (4.18 J) is twice as that needed to rise the temperature by 1.0 °C of 1.0 g of water (2.01 J).
- So, the temperature of maple syrup will be higher than that of water when CaCl₂ is added to both of them.
Not sure if I’m right, but it’s probably the water level where it started to become a drought, and it left lines.

Answer: 144 g</h3>
Explanation:
Mass of glucose = moles × molar mass
∴ Mass of glucose = 0.8 mol × 180 g mol⁻¹
= 144 g
∴ the mass of glucose you need to have 0.8 mol of glucose = 144 g
