A catalyst by definition is not consumed in a reaction. Therefore, the mass remaining after a reaction will be equal to the mass before the reaction. Note that in certain reactions, such as free radical halogenation, the catalyst may be lost by certain side reactions, however.
A catalyst, by definition, facilitates a reaction amongst other materials without itself being consumed in the reaction. So...however much you start with is how much you'll have at the end.
You can't because you do not have a concentration for the acid. The reaction is two alkali reacts with one acid.
Helium weighs about 1/7 the weight of air. Air weighs about 1.2 g / L. Helium weighs about 0.17 g / L. 10mL of Helium would weigh about 0.0017 grams.
10ml
Water
One mL
1
10ml is 0.01 litres
10ml is 10cm3
10ml of what? Water? Gravy?
10ml is 10cm3
10ml is 2/3 tablespoons approx
10mL x 1 tsp/4.9289mL= 2.03 tsp
1cL is equal to 10mL @10mL per cL
You can't because you do not have a concentration for the acid. The reaction is two alkali reacts with one acid.
1cl = 10ml 250cl = 250 x 10ml = 2500ml
what is the density of an 0bject that has a mass of 20g and a volume pf 10mL?
