How many moles of water are made from complete reaction of 1.4 moles of hydrogen gas? Given the reaction: 2H2 + O2 → 2H2O
Ber [7]

Answer:

1.4moles

Explanation:

From the balanced equation below;

2H2 + O2 → 2H2O

2moles of hydrogen reacts with 1mole of oxygen to produce 2moles of water.

since we are only interested in comparing hydrogen and water, we can say 2moles of hydrogen will produce 2moles of water

Hence by comparism of moles;

1.4moles of hydrogen will produce 1.4moles of water

When .080 moles of propane burn at STP, what volume of carbon dioxide is produced?
rodikova [14]

The volume of carbon dioxide produced is : 5.4 L

<u>Given data:</u>

moles of propane = 0.080 moles

<h3>Determine the volume of Carbon dioxide produced </h3>

The chemical reaction

C₃H₈  + 5O₂  ---- > 3CO₂ + 4H₂O

From the reaction

I mole of C₃H₈ = 3CO₂

0.080 moles of C₃H₈ =  3 * 0.080 = 0.24

Applying the equation below to determine the volume of CO₂

Pv = nRT

    = 0.24 * R * T

v = ( 0.24 * 8.314 * 273 ) / 1 atm

  = 544.7 ml = 5.4 L

Hence we can conclude that The volume of carbon dioxide produced is : 5.4 L

How does a buffer resist change in pH upon addition of a strong acid? The strong acid reacts with the strong base in the buffer
MrRa [10]

Answer:

The strong acid reacts with the weak base in the buffer to form a weak acid, which produces few H+ ions in solution and therefore only a little change in pH.

Explanation:

When a strong acid is added to the buffer, the acid dissociates and furnish hydrogen ions which combine with the conjugate of the weak acid, forming weak acid. The weak acid dissociates to only some extent and can furnish only some protons and there is no significant change in the pH.

Hence, option B is correct.

If a planet rotates 360 degrees during a 24 hour time period, what does that tell us about the planet? A. The middle of the plan
vlabodo [156]

The correct answer is C

<u />

<u>Explanation:</u>

360-degree rotation of the planet in 24 hours causes a 12-hour time clock. The earth rotates on its own axis and around the sun.

It completes one rotation on its own axis in 24 hours equal to 360 degrees which make one complete solar day. The part of the earth which is exposed to the sun has daytime while the other part experiences the night time.
