WILL REWARD BRAINLIEST ANSWER FOR WHOEVER CAN ANSWER ALL OF THESE :D (as you might be able to see, I can't chemistry to save my life lol, i just want to go to sleep man ;,]) 48.23 grams CO2 = L CO2

1.30 moles Ca3N2 = formula units Ca3N2

176.88 L He = atoms He

187.14 L NO2 = g NO2

7.51 grams H2O = Liters H2O

395.91 g NaBr = moles NaBr

21.81 g P = atoms

Convert 8.16 moles of H2O to grams.

2.78 mol Cl2 = L Cl2

Joan writes four numbers on the board in standard form, and then she writes their scientific notation

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?

Astudent completes a titration by adding 12.0 milliliters of naoh(aq) of unknown concentration to 16.0 milliliters of 0.15 m hcl(aq). what is the molar concentration of the naoh(aq)? 1)5.0 m 2)0.20 m 3)0.11 m 4)1.1 m
