Answer: False
Explanation:
It is not that it must have fossil fuels only because car can also work on hydro power and water. So it should be energy.

Answer:
3-methoxy-1-methyl cyclohexene
3-methyl-3- methoxy cyclohexene
Explanation:
The reaction of methanol with 3-bromo-1-methylcyclohexene leads to the formation of a resonance stabilized carbocation as shown in the image attached. The two products formed result from the two resonance structures of the intermediate carbonation.
The full mechanism of the reaction is shown in the image attached to this answer.
Based on the aforementioned measurements, the following applies;
- The measurements are not accurate
- The measurements are precise
<h3>What is accuracy and precision?</h3>
Accuracy is the exact conformity to truth, or to a rule or model or the degree of conformity of a measure to a true or standard value.
Precision is the ability of a measurement to be reproduced consistently or the closeness of measured values.
According to this question, the following measurements were made to determine the density of a material whose value was 3.75 g/mL
- Trial #1 - 4.75 g/mL
- Trial #2 - 4.76 g/mL
- Trial #3 - 4.74 g/mL
Based on the above measurements, the following applies:
- The measurements are not accurate because they are not close to the value of the handbook
- The trial measurements are precise because they are close to one another.

This picture sets a soothing scene, as the sunset lies over the trees. It is very calm outside because the wind is in no rush. It has to be winter because thy tree hath bare branches and the clouds settle down waiting for night. The moon is jealous because it can not create anything as beautiful.

To solve this we assume
that the gas is an ideal gas. Then, we can use the ideal gas equation which is
expressed as PV = nRT. At a constant temperature and number of moles of the gas
the product of PV is equal to some constant. At another set of condition of
temperature, the constant is still the same. Calculations are as follows:
P1V1 =P2V2
V2 = P1 V1 / P2
V2 = 153 x 3.00 / 203
<span>V2 = 2.26 L</span>
