How molecules of CO2 (g) are produced when 0.75 moles of propane are burned? Chemical reaction: C3H8 + 5O2 à 3CO2 + 4H2O
Ibuprofen is an anti-inflammatory with the formula C13H18O2. How many grams of ibuprofen are in 0.495 mol? How many moles of carbon are in 10.0 g of ibuprofen? How many moles of ibuprofen contain 1.15×1023 atoms of carbon?
Consider the combustion of propane gas,C3H8(g) + 5O2(g) 3CO2(g) +4H2O(l)Ho = -2,220 kJ/molPropane (just C3H8) is often used for gasgrills. Anyone who has every filled or moved those tanks knows theycan get pretty heavy.a) How many grams of propane are in 1 pounds ofpropane? Use the conversion 1 lb = 454 g. (Express your answersfor the next three questions in scientificnotation. For exampleuse 2.3e-5 to indicate a number such as 2.3 x10-5.)gramsb) How many moles of propane are in 1...
I am still not quite grasping how to complete this problem:Posted by K on Sunday, October 14, 2007 at 6:43pm. Many home barbeques are fueled with propane gas C3H8. What mass of carbon dioxide (in kg) is produced upon the complete combustion of 18.9L of propane (approximate contents of one 5-gallon tank)? Assume that the density of the liquid propane in the tank is 0.621g/ml. How do I start & work this question? I wrote a balanced equation: C3H8 +...
1. Will Cd + Zn2+ react? 2. Is Ni(OH)2 soluble in H2O? 3. Propane burns according to the following equation: C3H8 + 5O2 3CO2 + 4H2O How many grams of CO2 can form from 0.177 mol of propane? 4. Cinnamic acid is 72.96% carbon, 5.40% hydrogen, and the rest is oxygen. What is the empirical formula of this acid?
Considerthe combustion of propane gas,C3H8(g) +5O2(g) 3CO2(g)+ 4H2O(l)Ho =-2,220 kJ/molPropaneis often used for gas grills and is typically purchased by fillinga propane tank with 20 pounds of propane. How much heat canbeobtained by burning 8 pound of propane? Use the conversion 1 lb =454 g and express your answer in scientific notation. For exampleuse 2.3e-5 to indicate a numbersuch as 2.3 x10-5.

Assume that the density of the liquid propane in the tank is 0.621g/ml.How do I start & work this question?I wrote a balanced equation:C3H8 + 5O2 -> 4H2O + 3CO2Now, where do I go from here?
How many grams of O2(g) are needed to completely burn 35.9 g of C3H8(g)? C3H8 + 5O2 ---> 3CO2 + 4H2O
If we have C3H8 + 5O2 ---> 3CO2 + 4H2O a) How many liters of oxygen gas are required to react with 7.2 L of C3H8 if both gasses are at STP? b) How many grams of CO2 will be produced from 35 L C3H8 at 15 C and 1.65 atm? c) How many grams of water vapor can be produced when 15 L C3H8 at 15 C and 1.65 atm are reacted with 15 L O2 at -20.0 C...
