What causes a lunar eclipse? If the right answer will be brainiist. the moon blocks the sun's light
the moon blocks the earth's light
the earth blocks the sun's light
the sun blocks the moon's light

Explanation:

when some sunlight reaches the moon, the sunlight passes through earth's atmosphere, which causes earth's atmosphere to filter out most of the blue light, so it'll be "The sun blocks the moons light" it seems reasonable to the Explanation above, as the sunlight surpasses the moon leading to a lunar eclipse. This is what I personally think.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

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
