Phosphorus pentoxide react with sodium hydroxide
P4O10 + 12NaOH → 4Na3PO4 + 6H2O
The salt so formed is called sodium phosphate or trisodium phosphate.
Answer:
Methyl group
Explanation:
From the diagram shown, we can see that the family group CH3 is attached to the structure.
This is simply called a methyl group because it is derived from me than and written that way to show the direct bonding between carbon and the 3 hydrogen atoms.
Answer:
1.38x10⁻⁴ M
Explanation:
First, we <u>calculate the pOH of the solution</u>, using the <em>given pH</em>:
Now we <u>calculate the concentration of OH⁻</u>, using<em> the pOH</em>:
- [OH⁻] =
= 2.75x10⁻⁴ M
Following the reaction Ca(OH)₂ → Ca⁺² + 2OH⁻, we divide [OH⁻] by 2 to calculate [Ca(OH)₂]:
- [Ca(OH)₂] = 2.75x10⁻⁴ M / 2
Answer:
I feel like it could lead to flooding
Hey there!
1 mole has 6.022 x 10²³ atoms.
Multiply that by 3.2 because we have 3.2 moles.
3.2 x 6.022 x 10²³
1.9 x 10²⁴
There are 1.9 x 10²⁴ atoms in 3.2 moles of chromium.
Hope this helps!
