Select all the correct answers. a pot of water is heated over a fire, and then frozen peas are added to the hot water. what happens to the energy in this situation? the energy gained by the peas is lost by the water. the peas lose energy as they are heated in the water. energy is transferred from the peas to the water and the pot. the water receives energy both from the fire and from the frozen peas. energy is transferred from the fire to the pot, then to the water, and then to the peas.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

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

the answer is symmetrical : )
