Why must the reaction be anhydrous? when performing a grignard reaction it is also very important that the reaction be free from acetone (a chemical we commonly use to clean the glassware). why must the glassware be free from acetone? during the work-up step, aqueous hydrochloric acid is added to the reaction and a gas is observed. what is the composition of the gas? draw the reaction equation for the formation of the grignard reagent

The is a particle with one unit of positive charge a. proton b. positron c. electron d. nucleus awnser quick it is a important science test!

Explain that newton first law, second law and third law of motion?

Answer asap need it by wednesday morning carry out the following calculations on ph and ka of from data. i. calculate the ph of 0.02m hcl ii. calculate the ph of 0.036m naoh iii. calculate the ph of 0.36m ca(oh)2 iv. calculate the ph of 0.16m ch3cooh which has ka = 1.74 x 10-5 mol dm-3 v. calculate ka for weak acid ha which has a ph of 3.65 at 0.30m concentration vi. calculate the ka of a solution made by mixing 15.0 cm3 0.2m ha and 60.0 cm3 0.31m a-. [ph= 3.80] vii. calculate the ph of a solution made by mixing 15.0 cm3 0.1m naoh and 35.0 cm3 0.2m hcooh. [ka = 1.82 x 10-4 m]
