You mix 7.9 ml of the 43 g/L MO solution (molar mass is 327.33 g/mol), 3.13 ml of the 0.040 M SnCl2 in 2 M HCl solution, 5.49 mL of 2.0M HCl solution and 3.43 mL of 2.0M NaCl. What is the concentration of Methyl Orange in molarity units?

This element exists in adundance in the sun.explain how you would go about capturing sunlight.would this captured sunlight contain any of the element?

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)

Which liquid (h2o, h2o + soap, or h2o + salt) has the strongest cohesion and adhesion? (need now plz)
