Answer:
Water is a solvent, and CO2 gas and the powdered drink mix are both solutes.
Explanation:
In order to successfully answer this question, we need to remember that solutions consist of solutes and solvents.
Solutes are components of solutions that are dissolved (typically ionic salts if we have a polar solvent), while solvents are fluids (usually liquids) that provide a medium for the solutes to dissolve (water is the most common polar solvent for ionic salts, for example).
As a general rule, solvent is used in great excess, that is, it makes the greatest percentage in terms of mass of a particular solution.
Applying the theory above for this problem, notice that the greatest percentage of this solution belongs to water, besides, water is a common solvent in general. Thus, it is our solvent.
Also, solution would only have one solvent and one or several solutes. This leaves the two other components, carbon dioxide and powdered drink mix, as our solutes, as they have a lower percentage than our solvent.
Answer:
actually yes some tiny organisms can help fight off diseases and possibly are slightly better than meds
Explanation:
i actually read an article about it not to long ago and found out that new mexico found something very similar
hope this helps :) also if you can pls mark me as brainliest
Answer: It will be produced 276,3 mg of product
Explanation: The reaction of anthracene (C14H10) and maleic anhydride (C4H2O3) produce a compound named 9,10-dihydroanthracene-9,10-α,β-succinic anhydride (C18H12O3), as described below:
C14H10 + C4H2O3 → C18H12O3
The reaction is already balanced, which means to produce 1 mol of C18H12O3 is necessary 1 mol of anthracene and 1 mol of maleic anhydride.
1 mol of C14H10 equals 178,23 g. As it is used 180 mg of that reagent, we have 0,001 mol of anthracene. With it, the reaction produces 0,001 mol of C18H12O3.
As 1 mol of C18H12O3 equals 276,3 g, the mass produced is 276,3 mg.
Answer:
Model 1 represents the old geocentric model of the solar system and Model 2 represents the newer heliocentric model of the solar system.
Explanation:
Model 1 has earth in the center, therefore it is geocentric. the geocentric model of the solar system is old. Nobody believes in it anymore because it is scientifically inaccurate.
Model 2 has the sun in the center, therefore it is heliocentric. This is the newer model of the solar system.
I will show you with detailed work for NaCl, but follow the same procedure for the rest of the compounds.
Molar Mass - Find the molar mass of the Na and the Cl and add them together
Na - 23
Cl - 35.5
Add those numbers together 23 + 35.5 = 58.5 g/mol
Moles in 1 tsp:
The mass measured in 1tsp of NaCl was 18 g. To calculate the amount of moles you take the mass measured and divide it by the molecular weight.
18/58.5 = 0.3077 mol
Moles of each element:
To find the moles each element in the compound you multiply the moles of 1 tsp by the number of atoms of the element in the compound
Na - 1 in NaCl
Cl - 1 in Na Cl
so take 0.3077 * 1 = 0.3077 moles Na (and Cl in this case)
Atoms of each:
take the number of moles calculated and multiply that by Avogadro's number(6.023x10^23) for the number of molecules
So for both Na and Cl:
0.3077 * 6.023x10^23 = 1.853x10^23 atoms for both Na and Cl
