specifically this is qualitative chem. The two compounds are metal halides and the common condition which the test is proceeded is in acidic condition. The most suitable reagent for that is dil nitric acid.
I think its correct. lle is the least because it has the longest non polar R group, Ser has an OH the strongest polar group, His has NH group but are attached in ring which makes them least polar, Trp has 2 aromatic rings and Phe has 1 aromatic ring.
first you need to draw a molecular orbital diagram. it is with the diagram that can help you identify bonding and antibonding electrons.
both have different polarity. Polar substances can dissolve/mix with each other. non polar substances can dissolve/mix with each other. you cannot mix both polar and non polar substances. example: Oil is non polar and water is polar. you will find two distinct layers because o...
Reaction: Na2CO3 + CuSO4 --> CuCO3 + Na2SO4 CuCO3 is insoluble and so form ppt. mole ratio: Na2CO3 : CuSO4 1 : 1 actual mole of CuSO4 = Mv = 0.159M x 26.7e-3L =_______moles = moles of Na2CO3. volume of Na2CO3 = n/M where n is the mole of Na2CO3 and M is the molarity of Na2C...
a. a pencil and a book (totally different materials) b. this can be aldehyde and ketones c. salt and metal. they both conduct electricity though they have different structures.
ok. matter is everything that surround us. anything that has mass, energy etc. liquid, solid, gases are all matters. even anything that moved having a velocity or kinetic energy or mass or even anything we can't see is matter. i recommend that you read more on cathode rays...
i guess log is 10g???...stp is standard temperature and pressure. in this condition, 1 mole of gas contains 22.4L. Is it propyrie or propyne??? whateva it is, its an organic compound so would yield H2O and CO2 when combusted completely. here's what you must do; construct a...
this is mostly physics. ensure to give the correct subject so that experts can come at your aid asap.
Heat (Q) evolved is Q = mc?T where m is the mass in grams, c is the specific heat and ?T is the change in temperature. In this case, the change in temperature is in degreesCelcius and the energy is in calories. You can do conversion in the final answer to joules if you want us...
