Answer:
Explanation:
Magnesium when it oxidizes has a valence of 2.
Oxygen, when it mixes with something, has a valence of - 2
So Mg and O2 will form something, but what? The answer is MgO
Mg + O2 ===> MgO
To balance this equation, you need 2 Magnesiums on the right and 2 Oxygens also on the right. The left will need a two Magnesiums.
The balanced equation will be
2Mg + O2 ====> 2MgO
Answer:
H
Explanation:
Hydrogen is a nonmetal love:)
B , Biosphere is a special shell of the Earth inhabited by living organisms
Answer:
acceleration: 5 mi/h/s north
Explanation:
A quantity can be either vector quantity or scalar quantity, a vector quantity is a quantity with both magnitude and direction while a scalar quantity has magnitude only.
Examples of vector quantities include; velocity, acceleration, displacement , etc.
Acceleration is the rate of change of an object's velocity per unit of time. It is given by the formula; Velocity/time
Therefore in this case; a = 30 mi/h /6 s
= 5 mi/h/s
Therefore;
Acceleration = 5 mi/h/s
