False. The closest Shell to the nucleus is called the “1 shell” valence electrons are the electrons of an atom that are located at the uppermost shell of the electron, which is called the valance shell. it has 7 electrons in its second shell which is its outer most shell and so it will have 7 valance electrons.
The answer is b. The answer is false.
Answer:
no of moles=mass in gm÷molar mass so let x be the mass in gm
4.5=x÷35.5×2
x=4.5×35.5×2 grams
x=319.5 gm
Explanation:
formula
Ionic compound generally has high melting point due to the strong ionic bond. It is also hard but brittle because repulsion between oppositely charged ions will occur if force is applied. It is soluble in water but insoluble in non-aqueous solvent. It can only conduct electricity when molten or in aqueous solution and undergo chemical decomposition upon conducting electricity.
Answer:
18 CO2 + 16 H2O = C18H32O16 + 18 O2
