Answer:
C) Krypton is a noble gas, so it was difficult for chemists to find it, as though it was a secret.
Explanation:
the answer is : 4.6 M HCL
Answer:
F < O < Cl
Explanation:
Fluorine has a greater effective nuclear charge than oxygen does, meaning that the electrons are drawn tighter and closer toward the nucleus. Fluorine has 9 protons and 9 electrons while oxygen only has 8 protons and electrons. Chlorine has a larger atomic radius than both fluorine and chlorine because has another energy level (shell). Although chlorine has the same effective nuclear charge as fluorine, chlorine has more electrons, 17, which requires an additional shell to contain them.
Answer:
P1V1/T1 = P2V2/T2
Explanation:
- Hope that helped! Let me know if you need further explanation. Sorry I didn't give you exaxt one, it was kinda hard to read, but that is the correct answer I put above.
Answer: -
Solubility of a substance depend on the balance of intermolecular forces between the solvent and solute, and the entropy change that accompanies this process.
Temperature and pressure also plays a role in solubility.
A solution having Group 1 cations like lithium, sodium, potassium etc are always soluble.
A solution having NH₄⁺ is soluble.
All salts with anion as nitrates, acetates, chlorates, and perchlorates are soluble in water.
