The liquid is blue is an example of qualitative data. Qualitative data is data that can not be represented by numbers. The volume and density are both quantitative data.
1 mole CO₂----------- 6.02x10²³ molecules
4 moles CO₂ ---------- ??
4 x ( 6.02x10²³) / 1 =
= 2.41 x 10²⁴ / 1 => 2.41 x 10²⁴ molecules of CO₂
Answer C
H2SO4 is an acid
the chemical equation showing how H2SO4 is an acid according to the Arrhenius definition is as below
H2SO4 dissociate to give 2H^+ and SO4^2-
that is H2SO4 = 2H^+ + SO4^2-
According to Arrhenius an acid dissociate to give H^+ ions H2SO4 is an acid since it dissociate to give two hydrogen ions
