It is effected by diffusion (the power of smell and wind spread) but a solid is not.
Answer:
Coefficient of is more than 4
Explanation:
Oxidation:
- Balance charge: ......(1)
Reduction:
- Balance Cr:
- Balance O and H in acidic medium:
- Balance charge: .......(2)
gives balanced equation:
So coefficient of is more than 4
Answer:
starch: A soft white chemical made by all green plants. It’s a relatively long molecule made from linking together a lot of smaller, identical building blocks — all of them glucose, a simple sugar. Plants and animals use glucose as an energy source. Plants store that glucose, in the form of starch, as a reserve supply of energy.
Explanation:
Answer: a compound is a substance that is made up of more than one type of atoms bonded together, mixtures are a mix of multiple elements or compounds which haven't bonded together.
Explanation:
Answer:
1.04 mol
Explanation:
CO₂ is produced in a closed 100 L vessel according to the following equation.
CaCO₃(s) ⇄ CaO(s) + CO₂(g)
At equilibrium, the pressure of carbon dioxide remains constant at 1.00 atm.
First, we need to conver the temperature to the absolute scale (Kelvin scale) using the following expression.
K = °C + 273.15
K = 898°C + 273.15
K = 1171 K
Now, we can find the moles of carbon dioxide using the ideal gas equation.
