Answer:
Mass = 713.4 ×10⁻⁴ g
Explanation:
Given data:
Number of moles of calcium phosphate = 2.3×10⁻⁴ mol
Mass of calcium phosphate = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of calcium phosphate is 310.18 g/mol
by putting values,
2.3×10⁻⁴ mol = mass / 310.18 g/mol
Mass = 2.3×10⁻⁴ mol × 310.18 g/mol
Mass = 713.4 ×10⁻⁴ g
Answer:
The weight of ammonium phosphate is 10 gm
Explanation:
The chemical reaction of ammonium phosphate formation is as follows.
![3NH_{3}+H_{3}PO_{4} \rightarrow [(NH_{4})_{3}PO_{4}]](https://tex.z-dn.net/?f=3NH_%7B3%7D%2BH_%7B3%7DPO_%7B4%7D%20%5Crightarrow%20%5B%28NH_%7B4%7D%29_%7B3%7DPO_%7B4%7D%5D)
From the reaction one mole of phosphoric acid is equivalent to the one mole of ammonium phosphate.
So, "n" mole of phosphoric acid is equivalent to the "n" mole of ammonium phosphate.
Number of moles in 7.1 grams of phosphoric acid = 
<u>Formation weight of ammonium phosphate :</u>
Weight of ammonium phosphate = 
Round the answer to 2 significant digits
Weight of ammonium phosphate = 10 gm
C2H5 i think by ÷2 on both
Answer:
D. CF₄
Explanation:
The compound with this molecular geometry is Carbon tetrafluoride (CF₄)
Carbon tetrafluoride (CF₄) also known as Tetrafluoromethane, is known to be the simplest perfluorocarbon. The compound, tetrafluoromethane is the hydrocarbon methane has been perfluorinated. It useful as a refrigerant but known to be a greenhouse gas. Due to the nature of the carbon-flourine bond, it has very high bonding strength. Its bonds are known to be the strongest single bonds in organic chemistry.
Option D is the correct answer.
Because the space is ultimate thermos.
