Nope, this was confirmed by NASA senior space scientist David Morrison to be a hoax.
There's no such thing as Planet X / Nibiru.
There is no brown dwarf planet on a crash course with Eath.
Answer:
0.00663 grams/liter
Explanation:
HCl is a mineral acid with a molar mass of 36.46 g/mol.
No. of moles= mass/RMM
Making mass the subject of the formula:
Mass=Number of moles × RMM
Therefore 0.00040 mol HCl has a mass of:
0.00040 mol × 36.46 g/ mol
=0.01458 grams.
0.01458 grams are in 2.2 liters, Therefore 1 liter will have
0.01458 grams/2.2 liters= 0.00663 grams
concentration= 0.00663 grams/liter
Answer:
The answer to your question is Rb₃N
Explanation:
Data
Lithium Nitride = Li₃N
Rubidium Nitride = ?
Process
1.- Both Lithium and Rubidium are placed in group lA of the periodic table, which means that their valence number if + 1.
2.- Nitrogen is placed in group VA, which means that its oxidation number is -3.
3.- Write the formula and interchange the oxidation numbers.
Rb⁺¹ N⁻³
Rb₃N₁
But number one is not necessary to write it.
Rb₃N
