2.23 moles of propane react when 294 g of CO₂ is formed .
<h3>What is moles ?</h3>
Moles is a unit which is equal to the molar mass of an element.
A reaction is given
C₃H₈ +50₂ → 3CO₂ + 4H₂O
Grams of CO₂ formed = 294 gm
In moles = 294 /44 = 6.68 moles.
Let x be the moles of C₃H₈ is x
Mole ratio of CO₂ to C₃H₈ = 3 : 1
so
6.68 /x = 3/1
x = 6.68 /3 = 2.23 moles
Therefore 2.23 moles of propane react when 294 g of CO₂ is formed .

Answer:
should be A)Melts.Because magma is liquid i think
The density is 3 because the density remains the same.
Answer:
energy due to its velocity. We can compare potential and kinetic energy by considering a car on a hill. When the car is at the top of the hill it has the most potential energy.
Answer:
Step 1- CO2 and H2O enter the leaf.
Step 2- Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
Step 3- The electrons move down to enzymes.
Step 4-Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH
Step 5-The ATP and NADPH is used by the calvin cycle as a power source for converting carbon dioxide from the atmosphere into simple sugar glucose.
Step 6-The calvin cycle converts 3CO2 molecules from the atmosphere to glucose
Step 7-calvin cycle. The second of two major stages in photosynthesis (following the light reactions), involving atmospheric CO2 fixation and reduction of the fixed carbon into carbohydrate.
Hope this helps : D
