I believe the correct answer from the choices listed above is option D. The action that leads to crystal formation in minerals is that atoms or molecules form repeating patterns. Minerals are known to have a crystalline structure in which they exhibit short range and long range patterns.
Answer:
So we're trying to find the number of carbon moles in the compound. We know that we have 200g of the compound and that 40% of it is Carbon. and 40% of 200 is 80g (change 40% into a decimal and multiply it by 200 and you get 80g)
So 80g of the compound is carbon. In order to find the moles of Carbon, I have to divide the mass by the molar mass of the element.
We know from our periodic table that the molar mass for carbon is 12g/mol
<u>Therefore we have 6.67 moles of carbon in the compound</u>
A polar molecule is a molecule that has an overall dipole moment. This depends on the structure of the molecule.
The molecules that will be polar include;
A bent molecule with one polar bond and one non polar bond
A linear molecule with one polar and one non polar bond
A bent molecule with two equivalent polar bonds
A bent molecule with two non polar bonds
The presence of polar bonds does not automatically mean that a molecule will be polar.
Polarity also has to do with the structure of the molecule. This means the actual arrangement of atoms in the molecule.
All bent molecules are polar due to asymmetrical electron distribution in bent molecules.
However, a linear molecule with two equivalent polar bonds will be non polar since the dipoles will cancel out. If the linear molecule has one polar and one non polar bond, the molecule will have an overall dipole moment and will therefore be polar.

Answer:
4.4 g
Explanation:
The equation of the reaction is;
NaHCO3 (aq) + CH3COOH (aq) ----> CO2 (g) + H2O (l) + CH3COONa (aq)
Mass of baking soda - 4.5 g
Molar mass of NaHCO3 = 84.007 g/mol
Number of moles of baking soda= 4.5 g/84.007 g/mol = 0.0536 moles
If 1 mole of NaHCO3 yields 1 mole of CH3COONa
0.0536 moles of NaHCO3 also yields 0.0536 moles moles of CH3COONa
Hence;
Theoretical yield of CH3COONa = 0.0536 moles * 82.0343 g/mol = 4.4 g
Changes in the appearance of emission and absorption spectrums are caused by the activities of electrons.
When you transmit an amount of light on atoms, the state of the energy of electrons will become higher. Why? Because it is absorbing the light's energy. Not all wavelengths will be absorbed by the atoms, only selective.
I hope that the explanation is enough to prove that it is the correct answer. Have a nice day!
