Answer:

The results is Li₂O

Explanation:

n a chemical reaction, the electron miner in the formula must be balanced, that is, the number of positive and negative charges is the same

In this case, oxygen has a valence of -2 that is, it can give two electrons and lithium has a valence of +1, therefore two lithium atoms are needed for the charges to be neutral, therefore the chemical formula is

The results is Li₂O

uysha [10]

The SI unit for frequency is Hertz (Hz), or simply, the reciprocal of a second. It measures how fast an object could be moving. In this case, the frequency would be 16 wave crests per 8 seconds (16/8 = 2). In simplified answer, the frequency is 2 per second, or 2 Hz.

Answer:

Box 1 has more mass than box 2.

Explanation:

Box 1 has more mass than box 2, as it caused a greater affect in the change of speed of box 2. During a collision, the object with a lesser mass will be affected more, causing the velocity to change more. Because box one is greater than box 2, it caused a larger change in speed when they collided.

If two forces act on an object in different direction with different the resultant force is the difference between them.the object acts in the direction of greater force.
so, 300-150=150N
