Answer:
D:2
Explanation:
H is hydrogen, and the subscript represents the amount of atoms it has so H2SO is two hydrogens
Electron transitions from higher to lower energy levels cause emission of energy in the form of electromagnetic waves, each with their own specific wavelength. Because the energy levels of elements are quantized, each transition has a specific energy difference. The collection of these transitions makes up the emission spectrum and each spectrum is unique to a specific element, allowing identification.
D) carbon dioxide is the answer to your question
Answer:
Number of mole = 5moles
Explanation:
To find the number of mole of methane,we will use the formula
n = m/ Mm
n - moles
m - mass
Mm - molar mass
Since m - 80g
Let's calculate the molecular weight of CH4
C - 12
H - 1
Mw = 12 + 1 * 4
= 12 + 4
= 16g/mol
n = 80g/16g/mol
n = 5moles
