At night, the moon appears bright. which of the following explains this? a. the moon reflects the light produced by the sun. b. the moon releases the light it absorbed during the day. c. the light from the earth is reflected by the moon.

When the surface of moon reflects light from the sun, it results in shining of moon and regardless the fact that sometimes moon seems to shine brightly, the moon reflects between 3 to 12 percent of the sunlight which hits it. The moon brightness depends upon the position of the moon in orbit around the planet from the earth.

Hence, the correct option is A that is the Moon reflects the light produced by the Sun.

answer; talc and gypsum;

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
