Answer:
A) solute - NaCl, solvent - water
B) solute - O2 and other gases, solvent - N2
C) solute - ethanol, solvent - water
D) solute - tin, solvent - copper
Explanation:
Solute(s) is/are the minor component(s) in a solution, dissolved in the solvent.
Solvent is the component of a solution that is present in the greatest amount. It is the substance in which the solute is dissolved.
If both solute and solvent exist in equal quantities (such as in a 50% ethanol, 50% water solution), the concepts of "solute" and "solvent" become less relevant, but the substance that is more often used as a solvent is normally designated as the solvent (in this example, water).
Answer:
Explanation:
Inquiry making is one of the methodical approaches to scientific investigation. Inquiry basically deals with asking question and querying a certain procedure or observation. In almost all the phases of a scientific investigation, the scientist will not cease to keep on asking questions that are connected to the observations and how this can help to further broaden the scope of the experiment. In fact, every investigation in science is an inquiry into a phenomenon and this generates series of questions that need to be satisfied.
Since the particles can move, the liquid<span> can flow</span> <span>and take the shape of its container. Some insects, such as pond-skaters, are able</span><span> to walk on water without sinking. This is because the forces of attraction between the water particles pull the particles at the surface together.</span>
Answer:
C
Explanation:
Because together all of the electrons create a negative charge.That balances the positive charge of the protons in the atomic nucleus.
Answer:
The answer to your question is 1544 g of CO₂
Explanation:
Data
mass of octane = 500 g
mass of CO₂ = ?
Balanced chemical reaction
2C₈H₁₈ + 25O₂ ⇒ 16CO₂ + 18H₂O
Process
1.- Calculate the molar mass of octane and of carbon dioxide
C₈H₁₈ = 2[(12 x 8) + (1 x 18)] = 2[(96 + 18] = 2[114] = 228 g
CO₂ = 16[(12 x 1) + (16 x 2)] = 16[12 + 32] = 16[44] = 704 g
2.- Calculate the mass of carbon dioxide produced
228 g of C₈H₁₈ ---------------- 704 g of CO₂
500 g of C₈H₁₈ --------------- x CO₂
x = (500 x 704) / 228
x = 352000/228
x = 1544 g of CO₂
