Suppose you tired to carry out a double-replacement reaction by mixing together equal volumes of a solution that contained dissolved NaF and a solution that contained dissolved NaCl. Would you expect a reaction, if so write the balanced chemical equation?

In what two situations will a car have balanced force?

tell people

because of the force caused by you bouncing it

i would just put dear sir or maam or to whom it may concern

generate is when you or something gives off some thing such as the fire genirated heat

i think a greiger counter

oh you add the exponents I multipied, Thanks

A solution contains 4.44% by mass of NaI in water. Calculate the molarity of the NaI, if the density of the solution is 1.2711 g mL-1. i got the answer to be 8.48 M... the percent mass is irrelevant information, right? i figured out the answer just by the given density alone.

thanks a lot guys, i got it!!! :)

wow thanks! its so very clear!
