Answer:
It is an example of Arrhenius acid-base reaction.
Explanation:
- In this reaction, water acts as an Arrhenius base because it consumes a proton from sulfuric acid.
- In this reaction, sulfuric acid acts as an Arrhenius acid because it donates a proton to water.
- Lone pair on oxygen atom in water is used to bind the proton obtained from sulfuric acid.
- Proton attached to -OH group in sulfuric acid is being donated because it is loosely bounded to oxygen atom due to high polarity of O-H bond.
- Reaction:
- Mechanism has been shown below.
Explanation:
The steps given in the question are incorrect.
Step 1 should be convert atoms to moles (n). Step 2 should be convert moles (n) to mass (m).
Step 1
Use dimensional analysis to convert the number of atoms to moles.
1 mole atoms = 6.022 × 10²³ atoms
n(Ag) = 2.3 × 10²⁴ Ag atoms × (1 mol Ag/6.022 × 10²³ Ag atoms) = 3.8193 mol Ag
Step 2
Convert the moles of Ag to mass.
mass (m) = moles (n) × molar mass (M)
n(Ag) = 3.8193 mol Ag
M(Ag) = atomic weight on the periodic table in g/mol = 107.868 g Ag/mol Ag
m(Ag) = 3.8193 mol × 107.868 g/mol = 412 g Ag = 410 g Ag rounded to two significant figures
The mass of 2.3 × 10²⁴ Ag atoms is approximately 410 g.
Answer:
0.55 atm
Explanation:
According to Dalton's law of partial pressures,
The total pressure is the summation of the partial pressures of individual gases in a sample of non-reactive gases.
Since Neon and Argon are noble gases, they do not react with each other. So we can apply Dalton's partial pressure law.
P total = P Ar + P Ne
2.39 atm = P Ar+ 1.84 atm
P Ar = 2.39 atm - 1.84 atm
= 0.55 atm
Answer: B.) Ionic
Explanation: It is B because it is the type of bond that is most likely being presented in row 1.
