5 0
The correct answer among the choices  is option C. The ion that is part of all nucleic acids is phosphoric acid. Nucleic acids are large biomolecules that is important for all life forms. DNA and RNA are nucleic acids. These biomolecules are made from monomers called nucleotides. Each monomer is composed of 5 carbon sugar, a nitrogeneous base and a phosphate group.

Which has more atoms, 12.0 mol of C or 12.0 mol of Ca?​
mr_godi [17]

Answer:

they are equal.

Explanation:

1 mol = 6.022 × 10^23 (Avogadro's constant), which is the number of atoms in 1 mol of any element. Doesn't matter what their atomic mass is, although, of course, 1 mol of carbon weighs less than 1 mol of calcium, but its because their mass is different, but the point is, in 1 mol of any element there is 6.03*10^23 atoms

This is like saying, what weighs more, 10 kg of feathers or 10 kg of metal

A voltaic cell is constructed with two silver-silver chloride electrodes, where the half-reaction is
NemiM [27]
The silver chloride electrode usually functions as a redox electrode where the equilibrium is achieved between silver and its salt (silver chloride).
The half reaction for this electrode is as follow:
<span>AgCl(s)+e−→Ag(s)+Cl−(aq) where:
</span>(s) refers to solid state
(aq) refers to the aqueous state and 
e- is the electron

0.055 grams of PbSO4 is dissolved in 200.00 grams of H2O.
Greeley [361]

Answer:

Solution's mass = 200.055 g

[PbSO₄] = 275 ppm

Explanation:

Solute mass = 0.055 g of lead(II) sulfate

Solvent mass = 200 g of water

Solution mass = Solvent mass + Solution mass

0.055 g + 200 g = 200.055 g

ppm = μg of solute / g of solution

We convert the mass of solute from g to μg

0.055 g . 1×10⁶ μg/ 1g = 5.5×10⁴μg

5.5×10⁴μg / 200.055 g = 275 ppm

ppm can also be determined as mg of solute / kg of solution

It is important that the relation is 1×10⁻⁶

Let's verify: 0.055 g = 55 mg

200.055 g = 0.200055 kg

55 mg / 0.200055 kg = 275 ppm
