How does H2So4 break up to h+ & hso4 - ?
Katena32 [7]
H2So4 is a strong acid and a strong electrolyte which means that when this dissociates in water, the dissociation process is complete. The first dissociation is 

H2 SO4 = H + HSO4- 

This can further release H+ and dissociate SO4- instead already

What is the concentration of HNO3 if 9.80×10−2 mol are present in 705 mL of the solution?
nydimaria [60]

Answer:

The answer to your question is 0.13 M

Explanation:

Data

[HNO₃] = ?

moles of HNO₃ = 9.8 x 10⁻²

volume = 705 ml

Process

1.- Convert volume to milliliters

                 1000 ml ------------------ 1 L

                    705 ml ------------------ x

                    x = (705 x 1) / 1000

                    x = 705 / 1000

                    x = 0.75 L

2.- Calculate the molarity

Molarity = moles / volume

Molarity = 9.8 x 10⁻² / 0.75

Molarity = 0.13

What is the pressure (in atm) in a 5.00 L tank with 9.00 grams of oxygen gas at 350 K?
miss Akunina [59]

Answer:

1.61 atm

Explanation:

Using general gas law equation as follows:

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K)

From the information provided in this question,

V = 5.00L

T = 350K

mass of O2 = 9.00g

Using mole = mass/molar mass

Molar mass of O2 = 16(2) = 32g/mol

mole = 9/32

mole = 0.28mol

Using PV = nRT

P = nRT/V

P = 0.28 × 0.0821 × 350/5

P = 8.0458/5

P = 1.609

Pressure = 1.61 atm
