Answer:
name a food that contain an acid
1. nuts
2. dairy
3. grains
3. meat
If a solution is saturated, that means it already posses the maximum number of solutes thus have been dissolved in it, and thus the concentration cannot be increased.
Answer: 0,4278g of F and 0,4191g of Fe
Explanation: it's possible to calculate the mass of each element by multiplying the percentage (decimal) of the element by the mass of the compound.
For Fluorine (F)
0,847g * 0,5051 = 0,4278g of F
For iron (Fe)
0,847 * 0,4949 = 0,4191g of Fe
This is determined because even when the compound is decomposed, due to conservative law of mass, the decomposition process do not affect the amount of matter, so the mass of the elements remain even if they are separated from the original molecule.
At the end, the sum of the elements masses should be the total mass of the compound.
C. The number of neutrons
Since Carbon 12 has 6 neutrons
And carbon 13 has 7 neutrons.
You know that elements have equal protons (atomic number) and electrons
If polar covalent bonding results in a molecule with a positively-charged end and a negatively-charged end, the molecule is called D. a dipole.
