The student's lab manual says to mix 50 ml of his 2.0 m cacl2 solution with 50 ml of a 3.0 m aqueous solution of sodium carbonate(na2co3) a. write a balanced equation to show the reaction. include state symbols b. what kind of reaction is this? c. what is the limiting reagent? d. how many grams of precipitate should he get? e. if he got 8.29 of product, what is his percent yield?

We first assume that this gas is an ideal gas where it follows the ideal gas equation. the said equation is expressed as: pv = nrt. from this equation, we can predict the changes in the pressure, volume and temperature. if the volume and the temperature of this gas is doubled, then the pressure still stays the same.

Ithink it's the third answer

According to arrhenius theory of acid and bases, an acid is a proton donor, while base donates hydroxyl ions. further, acid and base reacts to form salt and water.consider following example.hcl    +      h2o          →      cl-          +      h3o+here, hcl has donated a proton, hence it is an acid.now consider following reactionhcl      +      naoh            ↔      nacl      +        h2oin this reaction, hcl donates proton, hence it is acid. on other hand, naoh donates hydroxyl ion (i.e. hence it is a base.
