what is the balanced equation for the reaction of solid magnesium metal with oxygen gas to produce solid magnesium oxide

GaryK [48]

Answer:

2Mg + O₂ ⟶ 2MgO

Explanation:

Step 1. Start with the most complicated-looking formula (O₂?).

Put a 1 in front of it.

Mg + 1O₂ ⟶ MgO

Step 2. Balance O.

We have fixed 2 O on the left. We need 2O on the right. Put a 2 in front of MgO.

Mg + 1O₂ ⟶ 2MgO

Step 3. Balance Mg.

We have fixed 2 Mg on the right-hand side. We need 2 Mg atoms on the left. Put a 2 in front of Mg.

2Mg + 1O₂ ⟶ 2MgO

Every formula now has a coefficient. The equation should be balanced. Let’s check.

Atom On the left On the right

Mg 2 2

O 2 2

All atoms are balanced.

The balanced equation is

2Mg + O₂ ⟶ 2MgO

Freezing point and boiling point of a substance P is -220 0 c and – 185 0c. A t which of the following range of the temperatures

Firlakuza [10]

Answer:

Between -195°C to -215°C

Explanation:

We begin from this data:

P under -220°C will be solid, because -220°C is the freezing point.

Above -220°C, P will be at liquid state.

Then -185°C is the boling point, so above that temperature we have P as a gas.

Between -175°C to -210°C

Above -185°C we said that P is gas, so at -175°C P is not liquid. This state is F.

Between – 190°C to -225°C

At -190°C, we can have P as liquid, but -225°C is under -220°C, where P changes from liquid to solid. Then, this state is also F.

Between -200°C to -160°C

Above -185°C we said that P is gas, so at -160°C P is not liquid. This state is also F. The same, as the first situation.

Between -195°C to -215°C

-195°C is a lower temperature than -185°C. P is still liquid, we did not get the boiling point yet. -215°C is higher than -220°C, P is also liquid. There are still 5°C until P completely freezes. This is the correct choice.
