In a chemical reaction, 300 grams of Magnesium (Mg) are combined with 100 grams of Oxygen (O) to form Magnesium Oxide. How much will the product 2MgO weigh?

An empty fuel tank can still contain and therefore can be even more dangerous than one full of liquid fuel.

Which diagram shows the correct way to represent an ionic compound of magnesium oxide?

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
