PLS ANSWER ASAP, WILL GIVE BRAINLIEST ANSWER

Stolb23 [73]

Answer:

.14L or 140mL

Explanation:

This is a classic plug-n-chug problem. Your textbook probably goes over this formula as $M_{1}V_{1} = M_{2}V_{2}$ . M stands for molarity of the given substance, and V stands for the volume that the substance occupies.

Simply plug in the values that you're given, like so:

$M_{1} = 1.5M\\V_{1} = ???\\M_2 = 7M\\V_2 = .03L$

$1.5M * x = 7M * .03L$

After completing the algebra portion and solving for the unknown, you will be left with x = .14L, which is the volume required to neutralize 30mL of 7M NaOH.

One gallon of pure isooctane is about 230 moles. How many moles of O2 would be required to completely combust one gallon of isoo

poizon [28]

Answer:

Explanation:

Hello,

At first, consider the balanced reaction for the combustion of the isooctane:

$C_8H_{18}+\frac{25}{2} O_2-->8CO_2+9H_2O$

Now, the stoichiometric relationship between the hydrocarbon and the oxygen leads to:

$molO_2=230molC_8H_{18}(\frac{\frac{25}{2}mol O_2 }{1mol C_8H_{18}} )=2875molO_2$

Best regards.
