The SI unit of specific heat is J per gram per degree
Celsius. Thus it follows that specific heat could be calculated in this way:
Specific Heat = Energy / (mass x change in temperature)
Thus,
Specific Heat = 3.912 cal / (9.84 oz x (191.2 ˚F – 73.2 ˚F))
Specific Heat = 3.369 x 10^-3 cal/oz-˚F
I think silicon(Si) is the best example of semiconductors
Answer:
72 g/L
Explanation:
The dissolved amount of solute is the difference between the amount you have poured and the amount that precipitated:
125 g - 35 g = 90 g
Thus, 90 grams of solute were dissolved in 1.25 liters. The saturation point is the ratio between the grams dissolved and the volume in liters:
saturation point = 90 g/1.25 L = 72 g/L
Answer:
Reduced species and oxidizing agent: sulfur in the form of sulfate.
Oxidized species and reducing agent: chromium in the form of chromous hydroxide.
Explanation:
Hello!
In this case, for the reaction:
We can see that the oxidation states of sulfur and chromium change from +6 to +4 and +3 to +6 respectively; in such a way, since the oxidized species is the same reducing agent because it undergoes an increase in the oxidation state, we infer that chromium is it as it goes from +3 to +6.
Moreover, since the reduced species is the same oxidizing agent because it undergoes a decrease in the oxidation state, we infer that sulfur is it as it goes from +6 to +4.
Best regards!
Answer:
1 mole of water (H2O)
Explanation:
Water has a chemical formula of H2O, there will be 2 moles of hydrogen in every mole of water.
In one mole of water, there will exist approximately 6.02×10^23 water molecules.
So, there will be a total of 6.02×10^23×2≈1.2⋅10^24 hydrogen atoms.
