Chemistry Worksheet Question

Hi, I answered all of my questions on my worksheet but there are two questions that Im a bit iffy about...can you help me with them? what are the two categories used to classify properties of matter?

What is the difference b/w deliquescent and hygroscopic substances

Give atleast 2 point of difference .I am not able to mark out the difference .-Deliquescent - loses water vapour - gets lighter. Hygroscopic - gains water vapour - gets heavier.-Lliverpool

Help me balance these chemical equations

Pb(NO3)2 + Na2CO3 --> PbCO3 + Na(NO3) Pb(NO3)2 + NaOH --> PbOH + Na(NO3) Pb(NO3)2 + KI --> PbI + K(NO3) Pb(NO3)2 + Na3PO4 --> Pb(PO4) + Na(NO3)-Pb(NO3)2 + Na2CO3 → PbCO3 + 2 NaNO3 Pb(NO3)2 + 2 NaO

Can glucose and amino acids be considered solutes

Im not sure?-If they get dissolved in something they are solutes.

What the heck is solid water

I think its ice but my prof wouldnt put something like that on a huge test tomorrow...-Its ice. Thats the solid form of water, I dont think its a trick question. Unless he wants you to think he wouldn

What small molecule is released during dehydration synthesis and consumed during hydrolysis

Technical Answer: An OH- Ion and an H+ ion are removed during dehydration, resulting in water. During hydrolysis, water is added in and broken apart into OH- and H+ ions and distributed. Simplest an

Chemistry question***

how do u do thiss? calculate wavelengh of an FM radio station with a frequency of 103.1 mHz-frequency and wavelength are two wave properties, which are related by the following equation: c = λv whe

How to figure out correct ratio to form a precipitate

I am trying to answer this question: a) If you were mixing 0.1 M NaOH (aq) and 0.1 M FeCl3 (aq) what would be the correct ration of drops to form the most precipitate? b) Would the use of phenolphthal

Question on equilibrium! urgent!

Toluene (methyl benzene), C7H8(g) is an important solvent and precursor to many other organic compounds such as trinitrotuluene (TNT). It can be produced according to the following equilibrium: C7H14(

A gas has a volume of 250. L at 67.8 C degrees. Determine the volume of the gas at 25.0 C degrees .

i really do not know how to do this? Can you please explain me how to do it?-first you have to realize the relationship between temperature and volume: as you heat a sample of gas you will cause more

One reaction that produces hydrogen gas can be represented by the unbalanced chemical equation

Mg (s) + HCl (aq) -> MgCl2 (aq) + H2 (g) What mass of HCl is consumed by the reaction of 3.42 mol of magnesium? Answer in units of g. Okay. So first, I balanced the equation to Mg+2HCl -> MgCl2 + H2
