Asubstance has a triple point at -24.5 ∘c and 225 mmhg. what is most likely to happen to a solid sample of the substance as it is warmed from -35 ∘c to 0 ∘c at a pressure of 220 mmhg? a substance has a triple point at -24.5 and 225 . what is most likely to happen to a solid sample of the substance as it is warmed from -35 to 0 at a pressure of 220 ? the solid will melt into a liquid the solid will sublime into a gas. nothing (the solid will remain as a solid).

answer; i do believe the correct answer is (river); /// good luck

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

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
