35g of CaCl2 is dissolved in 2.75L of water to form solution (s). CaCl2 dissociates in water according to the given equation :
CaCl2 Ca2+ (aq)+2C1-(aq) (dissociation equation)
M(CaCl2)= 111 g/mol
a-Calculate the molar concentration of CaCl2 in solution (s).
ration of Ca2+ ion and clion

A+b→2c when the reaction begins, the researcher records that the rate of reaction is such that 1 mole of a is consumed per minute. after making changes to the reaction, the researcher notes that 2 moles of a are consumed per minute. what change could the researcher have made to effect this change?

If 34.2 grams of lithium react with excess water, how many liters of hydrogen gas can be produced at 299 kelvin and 1.21 atmospheres? 2 li (s) + 2 h2o (l) yields 2 lioh (aq) + h2 (g)
