According to the basic facts, the only one non-charged subatomic particle from the scale is definitely neutrons because protons is always positively charged whereas elecrtons is <span>negatively charged. So, the right answer is A.</span>
Answer:
5.112 grams of simple sugar glucose is produced by the reaction of 7.50 g of carbon dioxide.
Explanation:
Moles of carbon dioxide =
According to reaction 6 moles of carbon dioxide gives 1 mole of glucose.
Then 0.1704 moles of carbon dioxide will give:
of glucose
Mass of 0.0284 moles of glucose:
0.0284 mol 180 g/mol =5.112 g[/tex]
5.112 grams of simple sugar glucose is produced by the reaction of 7.50 g of carbon dioxide.
Answer:
Sodium chloride solution:
First you need to calculate the mass of salt needed (done in the explanation), which is 58.44g. Then it have to be weighted in an analytical balance in a weighting boat and then transferred into a 2L volumetric flask that is going to be filled until the mark with distilled water.
Sulfuric acid dilution:
First you need to calculate the volume needed (done in the explanation), it is 16.6 mL. Using a graduated pipette one measures this volume and transfer it into a 2L volumetric flask that is already half filled with distilled water, and then one fills it until its mark.
Explanation:
Sodium chloride solution:
Each liter of a 0.500M solution has half mol, so 2L of said solution has 1 mol of salt. Sodium chloride molar mass is 58.44g/mol, so in 2L of solution there is 58.44g of salt. That`s the mass that`s going to be weighted and transferred to a 2L volumetric flask.
Sulfuric acid dilution:
This is the equation for dilution of solutions:
Where "c1" stands for the initial concentration (stock solution concentration), "v1" for the initial volume (volume of stock solution used), "c2" for the desired concentration and "v2" for the desired volume.
When we are diluting from a stock solution we want to know how much do we have to pipette from the stock solution into our volumetric flask. We do so by isolating the "v1" term from the dilution equation:
in this case that would be:
In CONVECTION, heat energy is carried by the movement of particles of matter. In CONDUCTION, heat is transferred by particles vibrating. In RADIATION, heat is carried directly by electromagnetic waves. When a hot object touches a cool object, heat moves from the hot one to the cool one.
The answer is D Transfer of heat through the movement of particles.
PLEASE MARK ME AS BRAINLIEST
The complex ion has a charge of -3 which means it is an anionic complex. The nomenclature for this complex can be broken in to two parts. The part that contains the cyano and the part that contains aluminium.
Cyano Ligand
There are 6 cyanide ions in the complex ion and so we assign the prefix hexa to explain the presence of 6 anions. This makes our ligand part be name hexacyano.
The aluminium part
Since the metal ion ends up in an anionic complex we add -ate at the end of aluminium to show that we have an anionic complex.
Henceforth we combine the two parts and start with the ligand in naming the complex. is called hexacyanoaluminate
