Is it possible for a balloon with an initial internal pressure equal to 250.0 kPa

If 2.03 g of oxygen react with carbon monoxide, how many grams of CO2 are formed?

mamaluj [8]

Answer:

The suitable equation for this reaction is

2CO + O₂ -----> 2CO₂

Here, we are given that we have 2 grams of O₂

From the equation, we can see that 2 * Moles of O₂ = Moles of CO₂

Moles of O₂:

2/32 = 1/16 moles

Therefore, the number of moles of CO₂ is twice the moles of O₂

Moles of CO₂ = 2 * 1/16

Moles of CO₂ formed = 1/8 moles

Mass of CO₂ formed = Molar mass of CO₂ * Moles of CO₂

Mass of CO₂ formed = 44 * 1/8

Mass of CO₂ formed = 5.5 grams

Hence, option B is correct

A chemist dissolves 716.mg of pure potassium hydroxide in enough water to make up 130.mL of solution. Calculate the pH of the so

Natasha_Volkova [10]

Answer: The pH of the solution is 13.0

Explanation:

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

Given mass of KOH = 716. mg = 0.716 g (Conversion factor: 1 g = 1000 mg)

Molar mass of KOH = 56 g/mol

Volume of solution = 130 mL

Putting values in above equation, we get:

$\text{Molarity of solution}=\frac{0.716\times 1000}{56g/mol\times 130}\\\\\text{Molarity of solution}=0.098M$

1 mole of KOH produces 1 mole of hydroxide ions and 1 mole of potassium ions

To calculate hydroxide ion concentration of the solution, we use the equation:

$pOH=-\log[OH^-]$

We are given:

[tex[[OH^-]=0.098M[/tex]

Putting values in above equation, we get:

$pOH=-\log(0.098)\\\\pOH=1.00$

To calculate the pH of the solution, we use the equation:

pOH + pH = 14

So, pH = 14 - 1.00 = 13.0

Hence, the pH of the solution is 13.0

When 2 moles of Na(s) react with H2O(l) to form NaOH(aq) and H2(g) according to the following equation, 369 kJ of energy are evo

enot [183]

Answer:

Exothermic

q = -8.03 kJ/g

Explanation:

When 2 moles of Na(s) react with H₂O(l) to form NaOH(aq) and H₂(g) according to the following equation, 369 kJ of energy are evolved.

The thermochemical equation is:

2 Na(s) + 2 H₂O(l) → 2 NaOH(aq) + H₂(g) ΔH = -369 kJ

Since the energy is evolved, the reaction is exothermic, which is why the enthalpy of the reaction (ΔH) is negative.

The heat released (q) per gram of Na(s) is (molar mass 22.98 g/mol):

$\frac{-369kJ}{2molNa} .\frac{1molNa}{22.98gNa} =-8.03kJ/g$

5) What is the volume of 6.70 x 10^15 molecules of propane, C3 H8 at STP?

lisabon 2012 [21]

Divide the number by 6.02 x 10^23 so the measurement is in moles and multiply by 22.4 to convert it into liters
