Pure magnesium metal is often found as ribbons and can easily burn in the presence of oxygen. When 3.44 g of magnesium ribbon burns with 6.82 gof oxygen, a bright, white light and a white, powdery product are formed. Enter the balanced chemical equation for this reaction. Be sure to include all physical states.

Explanation:

Mg + O₂ ⟶ MgO

1. Balance O.

We have 2 atoms of O on the left and 1 O on the right.

Put a 1 in front of O₂ and a 2 in front of MgO.

Mg + 1O₂ ⟶ 2MgO

2. Balance Mg:

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

2Mg + 1O₂ ⟶ 2MgO  

Every formula now has a coefficient. The equation should be balanced.

3. Check that atoms balance:

The equation  is now balanced.

explanation:

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
