Weapon used to break the blockade?
they used the power of the president to break it
What is the past tense of break with?
The past tense form of the verb "break" would be "broke".
What is the authors purpose in both Patrick Henry's speech and Thomas paines common sense?
To convince the colonists to break away from British rule
Why is it important to blow out the flame before the methanol is completely consumed?
Burning to dryness can cause your watch glass to break. Burning all the methanol allows for contamination to occur. Burning all the methanol off creates a dangerous flame. Burning to dryness can cause your watch glass to break. Burning all the methanol creates a hotter surface as the flame is trying to burn the dry salts. Blow out the flame before the methanol is completely consumed.
What method use to break surface tension?
a) Increasing the temperature of the solution b) Adding ethanol, methanol or other alcohols
Is methanol a volatile liquid at room temperature true or false?
ethanol Edit- this would be methanol because ethanol is a 2-carbon chain compared to the 1C in ethanol, and therefore has more intermolecular forces. As a result, molecules of ethanol would need more energy to break these intermolecular forces to be in a gaseous phase.
What is wiper fluid made of?
Wiper fluid is mostly water, with enough methanol added to prevent freezing, and a small amount of detergent to help break away bug scum.
Do covalent bond break into ions?
Sometimes, but not usually. The covalent bond in HCl, for example, breaks when the gas is dissolved in water, but the bonds in methanol, acetone, and most other organic compounds do not.
Is phthalic anhydride is soluble in methanol?
Phthalic anhydride is slightly soluble in methanol. But beware! In this case, phthalic anhydride will actually react with its solvent. This is called estrification of the anhydride. Methanol will break the ring of Phthalic anhydride and make an ester. C6H4(CO)2O + CH3OH --> C6H4(CO2H)(CO2CH3) Similarly, you might THINK Phthalic anhydride is soluble in water, but it actually reacts with water to make phthalic acid. If you want to make a true solution of phthalic anhydride, I would recommend acetone, or methylethyl ketone.
Why do small chunks of felt sometimes come out my 1993 accord ac vents when the heat is on?
This "felt" is a material used to quiet whistling noises as air flows through the ducts. Over time, the material has degraded and become brittle, allowing bits of it to break off. If you spray some toluene into the interior of the car with the system set to recirculate (not fresh air) this may help. Do not inhale any of the toluene however as it isn't good for your health.
Why does Cu have a greater boiling point than methanol CH3OH?
Cu has a lower boiling point than CH3OH because its particles are less polar. the CH3OH molecules have to have more kinetic energy to break the bonds between them and the surrounding molecules.
Why does the reaction of 2 2-dimethyloxirane with sodium methoxide in methanol gives primarily 1-methoxy-2-methyl-2-propanol?
Methoxide is your nucleophile; it will attack the C3 of 2,2-dimethyloxirane (the carbon that is attached to the oxygen, but doesn't have any methyl groups) via backside attack. This will cause the bond between C3 and the oxygen to break, thus releasing the chain and forming the oxide form of 1-methoxy-2-methyl-2-propanol. Since the oxide of this product is more basic than methanol, it will rip the hydrogen off of methanol, which will create the final product and regenerate methoxide.
Is water more polar than methanol?
yes
What is the difference between zeotropic and near-azeotropic?
zeotrope is a liquid mixture that shows no local maximum or minimum when vapour pressure is plotted as a function of composition.[1] Such a mixture is separable into its component parts by fractional distillation azeotropic distillation[1] is any of a range of techniques used to break an azeotrope in distillation. In chemical engineering, azeotropic distillation usually refers to the specific technique of adding another component to generate a new, lower-boiling azeotrope that is heterogeneous (e.g. producing two, immiscible liquid phases), such as the example below with the addition of benzene to water and ethanol. This practice of adding an entrainer which forms a separate phase is a specific sub-set of (industrial) azeotropic distillation methods, or combination thereof. In some senses, adding an entrainer is similar to extractive distillation.
Why does ethanol have a higher boiling point than methanol?
ethanol has a lower amount of intermolecular forces than water. These forces keep the molecules more uniformly in place in a liquid or solid. due to water's ability to have the intermolecular force of hydrogen bonding (which is very strong), the water molecules need more energy to break up these bonds, while ethanol needs less energy to break these bonds... energy in this case is heat, so water needs more heat to heat up and vaporize and ethanol needs less.
