Answer:
The answer to your question is: HCl = 58.44 g
Explanation:
To solve this problem, we must remember the law of conservation of mass that says that, matter cannot be created or destroyed, only changes its form.
That means that, the mass of the reactants must be equal to the mass of the products.
Process
Sodium (Na) + Chlorine (Cl) ⇒ Sodium chloride (HCl)
22.99 g 35.45 g x
22.99 + 35.45 = HCl
HCl = 58.44 g
By making it change probably
<span>Fluorine
For the group 17 elements (Halogens), the ionization energy decreases as the period increases (the elements become less reactive). And since of the 4 elements given, fluorine is from the lowest period, it has the highest ionization energy.</span>
Answer:
The mass percentage of the solution is 10.46%.
The molality of the solution is 2.5403 mol/kg.
Explanation:
A bottle of wine contains 12.9% ethanol by volume.
This means that in 100 mL of solution 12.9 L of alcohol is present.
Volume of alcohol = v = 12.9 L
Mass of the ethanol = m
Density of the ethanol ,d= 
Mass of water = M
Volume of water ,V= 100 mL - 12.9 mL = 87.1 mL
Density of water = D=1.00 g/mL
Mass percent
Molality :
M = 87.1 g = 0.0871 kg (1 kg =1000 g)
Answer is: Benzene is trigonal (or triangular) planar.
VSEPR theory (The Valence Shell Electron Pair Repulsion Theory) uses the AXE notation (m and n are integers, m + n = number of regions of electron density).
For benzene molecule (C₆H₆):
m = 3; the number of atoms bonded to the central atom.
n = 0; the number of lone pairs on the central atom.
