Suspension. The particles are big enough for the eye to see, and will separate if left sitting.
Molality pertains to a concentration of a mixture expressed in moles of solute per kg of solvent. Based on the given problem, the solute is the phosphoric acid with molecular weight of 97.99 g/mol. Assuming 1 g of sample, the mole of solute is equal to 0.244*(97.99) = 2.49x10-3 moles. The remaining percentage,t that is, 1-0.244 is the amount of solvent, which is equal to 0.756 g based on 1 gram assumption. Therefore, the molality is,
(0.244)*(mol/97.99 g)/(1-0.244)*(1 kg/1000 g) = 3.29 molala
To convert temperature in terms of kelvin to celsius, we subtract 273 to the given temperature in kelvin. In this problem, the given is 49 kelvin, thus, 49 - 273 is equal to -224 degrees celsius. The asnswer is <span>-224 degrees celsius. Kelvin is the SI unit for temperature.</span>
Answer:
You can determine x and y in the rate law by looking at experimental data and noticing how the change in concentration of a reactant is related to the reaction rate.
