Sucrose is not very soluble in ethanol; therefore, the particles of sucrose will be visible in the solution containing both sucrose and ethanol.
A map scale indicates the size of a mapped area.
I think 8, because you have to end up with a balanced equation.
To solve this we assume
that the gas inside the balloon is an ideal gas. Then, we can use the ideal gas
equation which is expressed as PV = nRT. At a constant pressure and number of
moles of the gas the ratio T/V is equal to some constant. At another set of
condition of temperature, the constant is still the same. Calculations are as
follows:
T1 / V1 = T2 / V2
V2 = T2 x V1 / T1
V2 = 293.15 x 300 / 333.15
V2 = 263.98 cm^3
