Answer:
c. ionic compound
Explanation:
Ammonium fluoride -
It is an inorganic salt , which has the molecular formula of .
As it is a salt , it is ionic in nature , i.e. , it has a cationic part and an anionic part , i.e. ,
is the cationic species .
And
is the anionic species.
is a crystalline solid , just like most of the salts , and has a very s alt salty taste to it.
Hence, from the given option ,
The correct option is ionic compound.
Ammonium fluoride is the inorganic compound with the formula NH4F. It crystallizes as small colourless prisms, having a sharp saline taste, and is exceedingly soluble in water.
Answer:
B. smaller and upside-down
Explanation:
Answer:
0.75 mol
Explanation:
Given data:
Number of moles of Na = 0.75 mol
Mass of water = 500 g
Moles of hydrogen gas produced = ?
Solution:
Chemical equation:
Na + H₂O → NaO + H₂
Number of moles of water:
Number of moles = mass/molar mass
Number of moles = 500 g/ 18 g/mol
Number of moles = 27.8 mol
now we will compare the moles of hydrogen gas with both reactant.
Na : H₂
1 : 1
0.75 : 0.75
H₂O : H₂
1 : 1
27.8 : 27.8
sodium will act as limiting reactant it produced small number of moles of hydrogen gas as compared to water.
Thus, number of moles of hydrogen gas are 0.75 mol.
Answer: 15.3 grams C
Explanation: 1 mole is 6.02x10^23 atoms. We can find the moles of C in 7.675 x 10^23 atoms of C by dividing:
(7.675 x 10^23 atoms C)/(6.02x10^23 atoms C/mole) = 1.275 moles C
The molar mass of carbon is 12g/mole. So the mass of 7.675 x 10^23 atoms is (1.275 moles C)*(12 g/mole C) = 15.3 grams.
