What else can I help you with?
Is glucose volatile or nonvolatile?
Glucose is nonvolatile because it does not easily vaporize at room temperature and pressure. It remains in the liquid form unless heated to a high temperature where it can undergo thermal decomposition.
Is the conversion of an alkene to an alkane a reduction or an oxidation?
The conversion of an alkene to an alkane is a reduction process. This is because the addition of hydrogen (H2) to the carbon-carbon double bond results in the reduction of the carbon-carbon double bond to a single bond, leading to an increase in the number of carbon-hydrogen bonds in the molecule.
Why is vapor pressure reduced in a solution with a nonvolatile solute?
Yes, nonvolatile solute lowers the vapor pressure and increases the boiling point. For instance, salt is an example of an nonvolatile solute in water. Ever wonder why salt is used in icy roadways in the winter? Because salt help inhibit the crystallization of water particles into ice by lowering the freezing point.
Which substance is left behind after you evaporate sugar solution?
Sugar is 'left over' because it is nonvolatile
Explain why vapor pressure is reduced in a solution with a nonvolatile solute?
I have researched the Internet on your behalf and found a web site that appears to address your question. The link to the web site is called RAOULT'S LAW AND NON-VOLATILE SOLUTES and is displayed directly below this window.

How does the addition of solute affect freezing and boiling point and vapor pressure on a solvent?
A non-volatile solute affects increases osmotic pressure. This is a colligative property. There will be a higher osmotic pressure required to prevent the solvent from flowing into the solution because the solvent has a higher chemical potential without solute in it.
What decreases as air rises that allows it to expand?
As you go up in elevation, the local air pressure drops, because there is less air above you to push Dow (gravity) to produce the pressure. Less pressure allows the air to expand.
Why the pressure of oxygen becomes low at high altitudes?
At higher altitudes, the air pressure decreases because the air molecules are more spread out. This reduction in pressure means there are fewer oxygen molecules available in the air to be breathed in, leading to lower oxygen levels at high altitudes.
What chemical change occurs when more reactive substance replaces a less reactive substance in a compound?
reduction or oxidation example: (this isn't a real reaction) ClO + CS4 --> CO + ClS4 the chorine has been reduced, because the carbon is more reactive the carbon has been oxidised, because it is more reactive oxidation = the addition of oxygen reduction = the subtraction of oxygen
What happens to air pressure as it rises in the atmosphere?
As air rises in the atmosphere, air pressure decreases. This occurs because the weight of the air above decreases with altitude, leading to lower pressure at higher elevations. Additionally, the expansion of air as it rises contributes to the reduction in pressure, as the air molecules spread out further in the lower density environment.
What is Nonvolitale RAM?
There is no non-volatile RAM, because a hard-drive is what is nonvolatile, because it retains its memory even after there is no power to the computer. RAM is volatile, because when there is no power all data that was stored in the RAM is lost.
Why reduction reaction is called reduction?
Because it gains electrons ,therefore its valency decreases : it becomes Negative
