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.
40.08 is the answer to your questions
The way to start it is simply by converting 0.239 L of dinitrogen oxide gas into moles of gas using the ideal gas equation
at STP , 1 mol of gas is 22.4 L of gas, or you could simply use pv = nRT
hope this helps
Explanation: A thermochemical equation is a balanced chemical equation which require an enthalpy change.
A balanced equation is the equation in which number of atoms on reactant side is same as the number of atoms on product side.
A thermochemical equation for is:
Here, heat is released in the reaction hence, it is a type of exothermic reaction.
A thermochemical equation for is:
Here, heat is absorbed in the reaction hence,it is a type of endothermic reaction.
