Answer:
0.305 mol
Explanation:
Ca(NO) is not a molecule. I think you meant to type Ca(NO3)2, which is calcium nitrate.
The moles of a compound is equal to is mass divided by its molar mass.
The molar mass of Ca(NO3)2 is 164.09 g/mol.
50.0 / 164.09 = 0.305
B because binary compound is a compound of two chemicals
The answer is c because it is helpful to understand the balance between these two ions. An aqueous solution is a solution in which water is the solvent. Water molecules (H2O) are polar, meaning that they have a negative end (the oxygen) and a positive end (the hydrogens). When there is a reaction in an aqueous solution, the water molecules have the ability to attract and temporarily hold a donated proton (H+). This creates the hydronium ion (H3O+).
Answer: an organic base, a phosphate group, and a sugar
Explanation:
A nucleotide is made up of 3 parts. We know a nucleotide is not made up of water so we are left with 2 choices. Nucleotides are made up of phosphate group, 5-carbon sugar, and nitrogenous base. The nitrogeneous base is typically adenine. The answer choice that matches this the closest is an organic base, a phosphate group, and a sugar.
The organic base is the nitrogeneous base and the sugar is the 5-carbon sugar.
