Salad would be a mixture because it is not chemically combined, if needed you could physically take it apart. So your answer would be A.)
Answer:
D. Silicon
Explanation:
A anion is a negatively charge ion resulting from the imbalance of protons and neutrons where there are more electrons than protons. Silicon has 4 valence electrons and is more likely to form an ionic bond with another atom(s) that will give it the 4 electrons it needs to become stable.
Answer:
D i think, sorry if its wrong
Explanation:
The molar solubility is the Pb ions present. PbCO3 dissociate to form Pb ions and CO3 ions
Ksp 7.40x10^-14 is equal to (Pb ions) (CO3 ions)
Pb ions correspond to CO3 ions
(pb ions)( Pb ions) is equal to 7.40x10^-14
therefore Pb ions is square root of 7.4x10^14 which is 2.27x10^-7m
In g/l is (2.27x10^-7) x 267(RFM of PbCO3) which is 6.06x10^-5 g/l
Answer:
Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions. The amount of a substance that can dissolve in a liquid (at a particular temperature) is called the solubility of the substance.
