What is the relationship between kinetic energy and mass?
Solnce55 [7]

Answer:

The equation for Kinetic Energy is: KE = 1/2 mv2. Kinetic energy has a direct relationship with mass, meaning that as mass increases so does the Kinetic Energy of an object. The same is true of velocity. However, mass and velocity are indirectly related.

Which is a way that biotechnology has Not helped society? Bacteria is used to grow vaccines in large quantities. Drugs can be de
fenix001 [56]
Well, you just have to look for the one that does not have any positive/benefit.

1. is not the answer, since vaccines prevent countless people from disease and death. 

2. is not the answer since animal abuse is not okay and the statement shows that science has become more efficient, therefore helping society become more efficient

3. is definitely not a positive effect that biotech has had on society. antibiotic-resistant bacteria endangers everyone. Therefore, this is the answer :)

4. is not the answer because helping people with diabetes be able to afford their medication is very helpful.

How much heat in kj is released by burning 9.5 grams of methane?
tatyana61 [14]
Methane is the compound CH4, and burning it uses the reaction:

CH4 + O2 -> CO2 + H2O, which is rather exothermic. To find the heat released by burning a certain amount of the substance, you should look at the bond enthalpy of each compound, and then compare the values before and after the reaction. In methane, there are 4 C-H bonds, which have bond energy of 416 kj/mol, resulting in a total bond energy of 1664 kj/mol. O2 is 494 kj/mol. Therefore we have a total of 2080 kj/mol on the left side. On the right side we have CO2, which has 2 C=O bonds, each at 799 kj/mol each, resulting in 1598 kj/mol, and H2O has 2 O-H bonds, at 459kj/mol each, resulting in a total of 2516 kj/mol on the right hand side. Now, this may be confusing because the left hand side seems to have less heat than the right, but you just need to remember: making minus breaking, which results in a total change of 436kj/mol heat evolved.

Now it is a simple matter of find the mols of CH4 reacted, using n=m/mr.

n = 9.5/16.042 = 0.592195 mol

Therefore, if we reacted 0.592195 mol, and we produced 436 kj for one mol, the total amount of energy evolved was 436*<span>0.592195 kj, or 258.197 kj.</span>
