7 0

Answer:

A reaction rate is a measure of how fast a reactant disappears or a product forms during a reaction.

Explanation:

It is usually defined as the change in concentration per unit time:

Δ(concentration)/Δt

The units are (moles per litre) per second.

In symbols, the units are mol/(L·s) or mol·L^-1 s^-1.

Sawing a board in half is an example of a chemical change
koban [17]

Sawing a board in half is a physical change not a chemical change the board doesnt change wood or whatever material it is is still would still be wood
If it were burned it would be a chemical change but its properties stay the same atomically so thats why its not a chemical change.

What is the product when magnesium reacts with nitrogen? Mg(s) + N2(g) → Mg2N3(s) Mg3N(s) Mg3N2(s) MgN3(s)
bixtya [17]
Look at the periodic table to find the charge on atoms.
 Magnesium is +2 and Nitrogen is -3. Since there are two nitrogen charge 2*-3 = -6 there needs to be 3 Mg then (3*2+ = 6+) to pair with the two nitrogen.
3 Mg(+2) + 2 N(-3) = Mg3N2
