3. Living organisms are made up of cells. Cells are organized at different levels to form very complex living organisms like your body. Each level has a
specific role or job to perform.
Which of the following lists these levels in the correct order of organization
from the simplest to the most complex?

The answers are above

cells, tissues, organ, organ systems, organisms

Explanation:

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

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
