Answer:
<u>Metallic Bond</u> <span>is described as electrons in a matrix of positively charged atoms.
Explanation:
Metallic bond is a type of electrostatic interactions between a positive charged metal atoms and a negatively charged electrons present in surrounding of metal atom. The strngth of the interactions depend upon the number of electrons and the number of positive charges carried by the positive cations. Greater the number of positive charges greater is the strength of interactions. Therefore, it will effect its physical properties like increase in melting and boiling points.</span>
Answer:
It seems to be a folded filter paper. But the answer could be funnel as well.
Answer:
The ocean holds about 97 percent of the Earth's water; the remaining three percent is found in glaciers and ice, below the ground, in rivers and lakes. Of the world's total water supply of about 332 million cubic miles of water, about 97 percent is found in the ocean.
wait..if you asking about the country it's Brazil✌️
Mole percent of O2 = 10% = 0.1 moles
Mole percent of N2 = 10% = 0.1 moles
Mole percent of He = 80% = 0.8 moles
Molar Mass of O2 = (2 x 16) x 0.1 = 3.2
Molar Mass of N2 = (2 x 14) x 0.1 = 2.8
Molar Mass of He = 4 x 0.8 = 3.2
1. Molar Mass of the mixture = 3.2 + 2.8 + 3.2 = 9.2 grams
2. Since at constant volume density is proportional to mass, so the ratio of
mass will be the ratio of density.
Ratio = Molar Mass of the mixture / Molar Mass of O2 = 9.2 / 32 = 0.2875
