Mrs. Hendren has decided that she would like to grow some tomatoes and wants to know how much light is the best amount. So she plants tomato seeds in 4 different pots and leaves one pot in the dark, gives 6 hours of light a day to the second, eight hours of light a day to the third, and ten hours of light a day to the fourth. After 3 months she measures the size of the tomatoes grown. Group of answer choices What is the independent variable in this experiment? Correct Answer The different amounts of light given What is the dependent variable? Correct Answer The same type of tomato seeds and 3 months What are the constants in this experiment? [ Choose ] What would the control group be in this experiment? [ Choose ]

56 moles of   lieter in chemistry

a corroding iron, if that's one of your choices

is there any options? maybe im just not seeing them but i need the options to

-love shrooms

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
