Reduction of copper oxide by 4-channel gas
In the calculation, the mixture of 30g potassium rhodanate and MoO2 is heated until no gas is released, and the remaining solid is 20.4g
How many grams of O2 can one survive?
2. What is the mass of potassium citrate in the original mixture?
3. How many grams of those substances are contained in the residual solid after reaction?
You don't have to do the front one

The box with a volume of 12 liters must be able to hold 4 pieces of iron with a volume of 3 cubic decimeters, right? Why?

No
The length and width are different. They are put in
If it's liquid, it's OK

Judgment question: the volume of a cube box with an edge length of 1 decimeter is 1 decimeter 1 cubic decimeter ()

Yes

In the formula P = ρ GH, does density refer to the density of an object or the density of a liquid?

It depends on the object
If it is used to calculate the pressure of a liquid, the density is the density of the liquid
If it is used to calculate the pressure at the bottom of a cylinder placed on a horizontal plane, the density is the cylinder density
