Which of the following numerical expressions gives the number of particles in 2.0 g of Ne?

Response: B- 22.2 kg

Explanation: Given that three potatoes weigh 667 g, it's implied that one potato weighs 667/3= 222.33 g (approximately), leading to the conclusion for 100 potatoes being 100*222.33= 22233 g, which converts to 22.2 kg since 1 g=1000 kg

Answer:

0.008945 atm

Explanation:

In the reaction:

2H2S(g) ⇌ 2 H2(g) + S2(g)

Kp is defined as:

Where P represents the pressure of each component at equilibrium.

Starting with an initial pressure of H2S at 3.00 atm, the equilibrium concentrations are:

H2S = 3.00 atm - 2X

H2 = 2X

S2 = X

Substituting these values into the equation gives:

0 = 4X³ - 1.28x10⁻⁶X² + 1.92x10⁻⁶X - 2.88x10⁻⁶

Calculating X yields:

X = 0.008945 atm

In equilibrium, the pressure of S2 is X, so the pressure stands at 0.008945 atm

Answer:

The salt identified is barium chloride.

Explanation:

The moles of barium sulfate produced are

per the reaction, 1 mole of barium sulfate arises from 1 mole of .

Therefore, 0.0480 moles result from:

of .

The quantity of used amounts to 10.00 g

Moles of = \frac{10.00 g}{\text{Molar mass}}[/tex]

The molar mass of is 208.33 g/mol

The closest answer to our calculation is .

The correct identification is barium chloride, which has a molar mass of 208.2 g/mol.
