8.03 Solutions Lab Report
In this laboratory activity, you will investigate how temperature, agitation, particle size, and dilution affect the taste of a drink. Fill in each section of this lab report and submit it and your pre-lab answers to your instructor for grading.
Pre-lab Questions:
In this lab, you will make fruit drinks with powdered drink mix. Complete the pre-lab questions to get the values you need for your drink solutions.
Calculate the molar mass of powered fruit drink mix, made from sucrose (C12H22O11).
Using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 M solution of 100 mL.
Answer:
0.940mol &
0.000301mol respectively.
Explanation:
number of moles = given mass / molar mass
given mass of Nacl = 55g Molar mass = 23 + 35.5
n=m/M = 55g/58.5g/mol = 0.940mol
note- (add the atomic weights of sodium and chlorine to get the molar mass of Nacl.) = 58.5g/mol
similarly, NaCO3 = 23 + 12 + 16*3 = 83g/mol
n=m/M = 0.025g/83g/mol = 3.01 * 10^-4 = 0.000301mol
extra: If you ever get asked to put it in number of particles just use the relation of 1mole = 6.02 * 10^23 particles.
Answer:
The pendulum will begin to swing in the direction of the unbalanced force
Explanation:
The action of an unbalanced force on a pendulum will cause the pendulum to go into oscillation.
It must be stated that an unbalanced force causes acceleration of an object, in the direction of that force. Hence, unbalanced forces always set an object in motion.
The best and most correct answer among the choices provided by the question is the second choice. <span>The formation of gas-to-liquid synfuel usually involves</span><span> the removal of carbon atoms from the fuel adding highly acidic substances such as hydrochloric acid. </span><span>I hope my answer has come to your help.

Answer:. an ionic compound
Explanation:
If it conducts electricity when molten, then it is an ionic compound. No covalent compound conducts electricity in molten state because their crystal lattice is not composed of ions. There are ionic solids which conduct electricity when molten but are insoluble in water such as alumina Al2O3. The solid is soluble in strong acid solutions.
