Three unknown acid solutions are labeled A, B, and C. One is sulfuric acid, one is hydrochloric acid, and the other s nitric acid. Each has a concentration of approximately one molar. Using only aqueous regents of 0.20 M lead (II) nitrate and 0.50 M calcium nitrate, write a short, concise experimental procedure, the results of which will be sufficient to identify each of the unknown acids. Tell what you would expect to see and what it means. Write net ionic equations to illustrate your answer.

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

the pseudoscience are like beliefs, theories, or like practices that are considered scientific

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
