Answer: The various planets are thought to have formed from the solar nebula, the disc-shaped cloud of gas and dust left over from the Sun's formation. The currently accepted method by which the planets formed is accretion, in which the planets began as dust grains in orbit around the central protostar.
Explanation:
Hope this helps.
Answer : C
Explanation:
a star produces energy by combining two atoms into one creates a powerful burst of energy
Hey there!
Mass of NaCl = 4.78 g
Molar mass of NaCl = 58.44 g/mol
Volume of solution = 12.34 mL
Number of moles:
n = mass of solute / molar mass
n = 4.78 / 58.44
n = 0.08179 moles of NaCl
Volume in liters:
12.34 mL / 1000 => 0.01234 L
Therefore:
Molarity = number of moles / Volume ( L )
Molarity = 0.08179 / 0.01234
Molarity = 6.62 M
Hope that thelps!
Answer : The limiting reactant is
Explanation : Given,
Mass of = 30.0 g
Mass of = 75.0 g
Molar mass of = 44 g/mole
Molar mass of = 32 g/mole
First we have to calculate the moles of and .
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 5 mole of react with 1 mole of
So, 2.34 moles of react with moles of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.
Therefore, the limiting reactant is
