Calculate the final temperature of the water from the following heat transfer experiment. 28 g of water at an initial temperature of 52 oC (Celsius) is added to 100.0 g of water at 100.0oC. The experiment is performed in an insulated container to prevent heat loss to the surroundings. Specific heat of water = 4.184 J/(g oC) State your answers in degrees celsius (C) with 3 significant figures.

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
