Given that sin = 3/5 and lies in quadrant II, find the following value. cos

Velocity is speed with a direction. In this case, there is no direction, so just put the speed. It would be 200m per 2 minutes = 100m per 1 minuite = 6000. per hour = 6 km h-1 (km/h) will

In step 1), I balanced the equation to "7C3H8 +22O2 -->> 6CO2 + 28H2O +4CO +11C". Is this not correct, along with the rest of my answer? Excuse the my typo in my original when I put the coefficient for H2O as 284 when it should be 28. Thank you.

Could someone please tell me if I did this question correctly? An incomplete combustion reaction of 12.125 grams of propane proceeds as follows: 2C3H8 + 11O2 = 3CO2 + 4H2O + 2CO + C(s).How many grams of solid carbon residue are produced as a product? my answer: known: molar ma...
