Answer: Different elements. H2SO4 is a compound.
Explanation:
Element are the simplest substances and can't be broken down. Is a substance whose atoms all have the same number atomic number. The atomic number indicates the number of protons in the nucleus, and in a neutral atom it has the same number of neutrons. Therefore, for example, hydrogen is an element because it is an atom with a certain atomic number.
On the other hand, a compound is a mixture composed of two or more different elements. So, H2SO4 is made of three different elements, then it is a compound.
Not 100%, but I think it would be 0.0013 because the equation for Molarity is Moles of solute(Mol)/ Liters of solution(L)
Comets are objects in the space that is composed mainly of dust and ice. While approaching the sun, a tail grows. Comets have nucleus which represents the hard rock object. As it nears the sun, it heats up the comet causing it to vaporize. Meteors, on the other hand, are what we call "shooting stars". They are interplanetary dusts that burn up as it approaches the Earth's atmosphere.
