Greg’s table is incorrect because sand is insoluble in water.
Physical is something you can feel chemical is like a gas
Answer:
1125.75 cm³
Explanation:
We are given;
Initial volume; V1 = 673 cm³
Initial temperature; T1 = 275 K
Final temperature; T2 = 460 K
From Charles law, we can find the new volume from;
V1/T1 = V2/T2
V2 = (V1 × T2)/T1
V2 = (673 × 460)/275
V2 = 1125.75 cm³
Answer:
ethanol
Explanation:
CO2 is carbon dioxide
C2H5OH is ethanol and we know that because that is what is left after taking out the CO2
Number of moles:
1 mole ---------- 6.02x10²³ molecules
? moles --------- 9.45x10²⁴ molecules
1 x ( 9.45x10²⁴) / 6.02x10²³ =
9.45x10²⁴ / 6.02x10²³ => 15.69 moles of CH3OH
Therefore:
Molar mass CH3OH = 32.04 g/mol
1 mole ------------ 32.04 g
15.69 moles ----- mass methanol
Mass methanol = 15.69 x 32.04 / 1 => 502.7076 g
