The element bromine is not a reddish-brown liquid. Liquid is the substance bromine.
M=DV
M=3.103 g/mL * 19.8 mL = 61.44 g
Charge and uncharged particles
Answer:
Oxygen and sulfur
Explanation:
Alloys consist of metals fused together sometimes with additional components, such as carbon, to prevent metals from corrosion.
Oxygen and sulfur are two compounds consisting of non-metal atoms, O and S. Combining oxygen with sulfur would actually produce sulfur dioxide, a gas, in contrast to a metallic substance that is fused with some other metal or carbon.
That's the reason why combination of sulfur and oxygen wouldn't produce an alloy: it would produce a gas.
Answer: 7.56 moles
Explanation:
C3H8 is the chemical formula for propane, the third member of the alkane family.
Recall that based on Avogadro's number, 1 mole of any substance has 6.02 x 10^23 atoms
So 1 mole of C3H8 = 6.02 x 10^23 atoms
Z moles of C3H8 = 4.55 x 10^24 atoms
To get the value of Z, we cross multiply:
1 x 4.55 x 10^24 atoms = Z moles x (6.02 x 10^23 atoms)
4.55 x 10^24 atoms = Z moles x (6.02 x 10^23 atoms)
To get the value of Z divide both sides by 6.02 x 10^23 atoms
Z moles =4.55 x 10^24 atoms ➗ 6.02 x 10*23 atoms
Hence, Z = 7.56 moles
Thus, the number of propane, C3H8 is 7.56 moles
