Answer:
11 atoms
Explanation:
The formula for lead(II) bicarbonate is: Pb(HCO3)2.
Atoms in Pb(HCO3)2:
Pb=1, H=1×2, C=1×2, O=3×2
1+1×2+1×2+3×2
=1+2+2+6
=11 atoms
The best method to solve how many grams of sodium nitrate that will be dissolve in water at 20 degrees Celsius is to use solubility table. Based on the solubility table, 88.3 g will dissolve in water in a 100g NaNO3. Therefore, get the percentage and multiply it to 50g. The answer is 44.15g
Answer:
See explanation
Explanation:
XeF4 has a square planar structure. There are six electron pairs on the valence shell of the central atom. This gives rise to an octahedral geometry based on valence shell electron pair repulsion theory.
There are two lone pairs of electrons present on the central atom, hence the four bond pairs are found to occupy the corners of a square thereby giving a square planar compound. The two lone pairs are found above and blow the plane of the square.
