Mass Ag₂O needed = 107.416 g
<h3>Further explanation</h3>
Given
100 g Ag
Required
mass of Ag2O
Solution
Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements
mass of Ag in Ag2O :
= ((2 x Ar Ag)/molar mass Ag2O )x mass Ag2O
Ar Ag : 107,8682 g/mol
MW Ag₂O = 231,735 g/mol
Input the value :
mass Ag₂O=(mass Ag x MW Ag₂O) : (2 x Ar Ag)
mass Ag₂O = (100 g x 231,735 g/mol) : ( 2 x 107,8682 g/mol)
mass Ag₂O = 107.416 g
A primary consumer is a herbivore that feeds on producers. They are the first in the food chain to eat making them the primary consumers.
Heat required for a system
can be calculated by the product of the specific heat, temperature difference
and the mass of the system. We calculate it as follows:
Q
= mCΔT
Q
= 50(0.06)(1)
Q
= 3 calories
<span>Therefore,
the correct answer from the choices listed is the second option, 3 calories.</span>
Answer:
A Standard Hydrogen Electrode is an electrode that scientists use for reference on all half-cell potential reactions. The value of the standard electrode potential is zero, which forms the basis one needs to calculate cell potentials using different electrodes or different concentrations. It is important to have this common reference electrode, just as it is important for the International Bureau of Weights and Measures to keep a sealed piece of metal that is used to reference the S.I. Kilogram.
Answer:
C. ribosomes
Explanation:
Both prokaryotic and eukaryotic cells contain certain structures called ORGANELLES. They possess some in common and others are not found in one or the other. According to this question, a small, free-floating organelle made from nucleic acid and amino acid is found in both eukaryotes and prokaryotes. This organelle is RIBOSOMES.
Ribosomes are organelles responsible for the synthesis of protein in both eukaryotes and prokaryotes. They can be found free-floating or attached to endoplasmic reticulum. Ribosomes are predominantly made of RNA (nucleic acid) and proteins i.e. Ribosomal RNA (rRNA) and proteins is their structural constituent. Hence, the organelle in this question is RIBOSOME.
