Answer:
0.0305 moles of MgCO₃
Explanation:
In order to solve this problem, we first need to calculate the molecular weight of MgCO₃:
- MgCO₃ MW = Atomic mass Mg + Atomic mass C + (Atomic mass O)*3
- MgCO₃ MW = 24.3 + 12 + 16*3 = 84.3 g/mol
Finally we <u>divide the mass by the molecular weight</u>, to calculate the <em>number of moles</em>:
- 2.57 g MgCO₃ ÷ 84.3 g/mol = 0.0305 moles.
Fats are large molecules made of two types of molecules, glycerol and some type of fatty acid.
Answer:
Orange, blue
Explanation:
A way to determine the color of a compound is using the Crystal Field Theory (CFT), which depends on the wavelengths of the electromagnetic spectrum.
The spectrum is formed by different wavelengths, each one with a color. The color happens when the electron is excited, and the goes from a higher level. When it returns to its original energetic level, it releases a photon, in a color way.
So, in CFT, the substance is placed in a light with a mixture of colors. The photon will absorb the color of its wavelength and will reflect the other color, which will be seen in the solution. In this case, the mixed light was prepared with blue and orange colors.
Then, the Cu(H₂O)₆²⁺ ions will absorb the orange color, and reflect the blue one, and the solution will be blue. The beta-carotene will absorb the blue color and will reflect the orange, so the solution will be orange.
