No it is unsafe. Even if they are empty they cannot
Answer:
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.

The mass of magnesium oxide must be 40 grams
Explanation:
The law of conservation of mass states that the total mass of the reactant in a chemical reaction must be equal to the total mass of the products after the reaction has completed.
In this problem, we have:
Reactants:
Magnesium metal (mass: 24 grams)
Oxygen gas (mass: 16 grams)
Products:
Magnesium oxide (mass: ?)
According to the law of conservation of mass, the mass of the magnesium oxide must be equal to the sum of the mass of the magnesium metal and the oxygen gass. Therefore:
Mass (magnesium oxide) = 24 g + 16 g = 40 g
