Answer:
1.81 g of Benzoic Acid
Solution:
The balance chemical equation is as follow,
C₇H₅O₂Na + HCl → C₇H₆O₂ + NaCl
According to equation,
144.11 g (1 mole) C₇H₅O₂Na produces = 122.12 g of C₇H₆O₂
So,
2.14 g of C₇H₅O₂Na will produce = X g of C₇H₆O₂
Solving for X,
X = (2.14 g × 122.12 g) ÷ 144.11 g
X = 1.81 g of C₇H₆O₂
Answer:

Answer:
I think it's the state of the surrounding water because if the water holds impurities it will float and if it doesn't have impurities it will sink
Answer:
[Ba(OH)₂] = 0.21 M
Explanation:
Molarity is a sort of concentration for solute that determines the moles of solute contained in 1 L of solution (mol/L).
Solution's volume = 45.6 mL
We convert the volume from mL to L → 45.6 mL . 1 L/1000 mL = 0.0456L
Our solute: Ba(OH)₂
We convert the mass of solute to moles → 1.68 g / 171.33 g/mol =
0.00980 moles
Molarity → mol/L → 0.0980 moles / 0.0456L = 0.21 M
They will mostly fill the octet rule rather than the nonmetal counterparts. Especially in the case of hydrogen
