Answer:
b. protein
Explanation:
Proteins are biopolymers basically made of carbon, hydrogen, oxygen and nitrogen.
Triglycerides are made of a glycerol molecule esterified by three fatty acids.
Polysaccharides are carbohydrates, and therefore contain carbon, hydrogen, and oxygen.
The mineral salt contains mostly sodium chloride, although it contains some other minerals such as magnesium, potassium, iodine, among others.
Answer:
D. Convert the 0.2 kg of NaCl to moles of NaCl
Explanation:
The molality equation looks like this:
Molality = moles of solute / mass (kg) of solvent
In this case, the solute is NaCl and the solution is water. So, if you have been given NaCl in kg, you need to convert it to grams and then to moles in order to plug it into the equation.
Answer:
cu+2 ------ oxidation whereas Cu ------ reduction.
Explanation:
In the reaction, cu+2 is the place where oxidation occurs because this cupric ion losses electrons which causes +2 charge on it. we know that oxidation is the loss of electrons and reduction is the gaining of electrons so the Cu is the place or atom at which reduction occurs. Electrochemical cells have two electrodes, which is anode and the cathode. The anode is the electrode where oxidation occurs whereas the cathode is the electrode where reduction takes place.
Answer:
4084.808 grams (SigFigs: 4085 grams)
Explanation:
The molar mass of Iron fluoride is 112.84 g/mol.
To calculate the mass, multiply the molar mass by the number of moles.
36.2 mol * 112.84 g/mol = 4084.808 g
Convert to Sigfigs (if necessary):
4085 g
Answer:
false
