I Will Give Brainliest Please Help!!! Balance the following chemical equation by typing the coefficients in the drop-down boxes for the reactants and products. (Reactants are on the top line; products are on bottom line.)

[ Select ] NaBr + [ Select ] CaF2 --> [ Select ] NaF + [ Select ] CaBr2

Which of these best describes an ionic bond?

Using the first volume and temperature reading on the table as v1 and t1, solve for the unknown values in the table below. remember to use the rules of significant figures when entering your numeric response.

Given the data below for the reaction, 2 a + 2 b + 4 c => d + e + 3 f, the reaction is fill in the [ ] order in a, fill in the [ ] order in b, fill in the [ ] order in c and fill in the [ ] order overall.
