Answer:

27 liters of hydrogen gas will be formed

Explanation:

Step 1: Data given

Number of moles C = 1.03 moles

Pressure H2 = 1.0 atm

Temperature = 319 K

Step 2: The balanced equation

C +H20 → CO + H2

Step 3: Calculate moles H2

For 1 mol C we need 1 mol H2O to produce 1 mol CO an 1 mol H2

For 1.03 moles C we'll have 1.03 moles H2

Step 4: Calculate volume H2

p*V = n*R*T

⇒with p = the pressure of the H2 gas = 1.0 atm

⇒with V = the volume of H2 gas = TO BE DETERMINED

⇒with n = the number of moles H2 gas = 1.03 moles

⇒with R = the gas constant = 0.08206 L*Atm/mol*K

⇒with T = the temperature = 319 K

V = (n*R*T)/p

V = (1.03 * 0.08206 *319) / 1

V = 27 L

27 liters of hydrogen gas will be formed

Determine the number of grams of sodium carbonate needed to prepare 100.0 ml of a 2.5 m solution
SCORPION-xisa [38]

Answer:

26.5 g

Explanation:

First we convert 100.0 mL to L:

  • 100.0 mL / 1000 = 0.100 L

Now we <u>calculate how many moles of sodium carbonate are needed</u>, using the <em>definition of molarity</em>:

  • Molarity = moles / liters
  • moles = molarity * liters
  • 2.5 M * 0.100 L = 0.25 mol

Finally we <u>convert 0.25 moles of sodium carbonate into grams</u>, using its <em>molar mass</em>:

  • 0.25 mol * 106 g/mol = 26.5 g

Choose the incorrect answer below concerning absolute zero.
Nataly [62]
Is equal to 0 k .This is because an absolute zero temperature is the temperature in which nothing can be cooled. The standard measurment for temperature is celcius which is already 0 but when we are converting 0 K to celcius we will gwt 273 celcius which is definitely not an absolute zero
