A student reduces the temperature from a 300 cm3 balloon from 60°C to 20°C. What will the new volume of the balloon be?

1 answer:

4 0

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

To what volume should you dilute 134 mL of an 8.00 M CuCl2 solution so that 48.0 mL of the diluted solution contains 5.89 g CuCl

Tom [10]

Answer:

Explanation:

Number of moles of CuCl2 initially present = volume * molar concentration

= 0.134 * 8

= 1.072 mol.

Molar mass of CuCl2 = 63.5 + (2*35.5)

= 134.5 g/mol

Mass of CuCl2 = molar mass * number of moles

= 134.5 * 1.072

= 144.184 g

Mass of CuCl2 in 48 ml = 5.89 g in 48 ml

Volume = 5.89 * (48/144.184)

= 1.96 ml.

In water, oxygen shares a bond with two hydrogen atoms. oxygen is more ____________ than hydrogen, making the bond ____________

arlik [135]

Oxygen is more ELECTRONEGATIVE than Hydrogen, which means that the electrons in the atom are coaxed more toward the Central Oxygen atom. Because of this, the charge is not evenly distributed among the molecule, causing it to have positive and negative sides. This is what we call a POLAR molecule.
