Answer:
properties is the answer
there are about 115 elements, each of which has its own chemical. properties
The first thing you need to do is calculate the molar mass of C4H10. To do this, look at a periodic table for the atomic mass of carbon and hydrogen. For Hydrogen it's 1.008 amu. For Carbon its 12.01 amu. This means that a mole of hydrogen has a mass of 1.008 amu. So to calculate the molar mass of C4H10:
atomic mass of H * number of H atoms in one molecule + atomic mass of C * number of C atoms in one molecule
1.008 * 10 + 4 * 12.01
= 58.12 g
So one mole of C4H10 would have a mass of 58.12 g.
Now you were told to find the number of moles for 2.50 g, so you need to change 2.50g into moles
2.50g *1 mole/ 58.12 g = .043014 moles of C4H10
You know that for every mole of C4H10, there are 4 moles of Carbon
so
.043014 mole C4H10 * 4 mole C/1 mole C4H10 = .172 mol C
Now to find the number of atoms, use avogadros numbe5r
6.022 * 10^23 * .17 mol = 1.024 × 10^23 atoms your answer.The first thing you need to do is calculate the molar mass of C4H10.

Answer:10,900,000,000,000 ozone moles
Explanation:
Answer:
The correct answer is option A. They receive instructions in their DNA.
The DNA (deoxyribonucleic acid) or the genes present in the cell guides the fate of the cells during the process of cellular differentiation in the embryonic life of the multicellular organism. The signaling molecule change the genetic expression changes, by which the cells are differentiated.
Answer:Polar covalent bond
Explanation:Polar covalent bonds form between atoms with an electronegativity difference between 0.5 and 1.7.
