V = 550 mL = 0.550 L
V = 22.4 L/mol (STP)
M(CO₂)=44.01 g/mol
n(CO₂)=v/V
m(CO₂)=n(CO₂)M(CO₂)=vM(CO₂)/V
m(CO₂)=0.550*44.01/22.4=1.08 g
Yes a physical change can do that. A chemical change is like a burning candal
Answer:
C
Explanation:
if we were to followw the IUPAC
A. The number of valence electrons determines how it reacts with other elements.
<em>One to three valence electrons</em>: The element behaves like a metal and reacts with non-metals.
<em>Five to seven valence electrons</em>: The element behaves like a non-metal and reacts with metals.
<em>Four valence electrons</em>: Elements at the top of the Group are non-metals, while those at the bottom are metals.
<em>Eight valence electrons</em>: Elements have a complete octet, so they are generally unreactive.
