Complete the following questions. use of significant digits for this problem is optional. a) what is the force of 3.5 kg m/s2 equivalent in newtons? what is the force of 3.5 lbm ft/s2 equivalent to in lb,? b) if the acceleration of gravity at a point is g 32.174 ft/s2 and an object is resting on the ground at this point, is the object accelerating at a rate of 32.174 ft/s2? c) suppose an object weighs 32.174 lb, at sea level. what is its mass in both lbm and in slugs? note that a slug is equal to 1 (lb*s? /ft). would its mass be greater, less, or the same on pluto? d) suppose a stone monolith has a mass of 10,000 lbm on earth. what is its weight in both lbf and in poundals? note that a poundal is equal to (1 ibn*ft/ would the monolith's weight be greater, the same, or less on pluto?

chemical properties are the characteristic of matter which can only be observed by changing the chemical identity of a sample like flammability reactivity and toxicity.

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
