Corey's Science Experiment 1. Purpose: To determine the effect that completely burning a log has on the weight of the log and to

calculate the amount of energy transferred in the process. 2. Corey selects a log for the project. 3. He completely burns the log in a controlled environment. 4. He collects all of the ashes and soot which remain after the burning is complete. 5. He weighs all of the remains and calculates the amount of weight and energy transferred in the burning. What is wrong with the steps of Corey's experiment? A. The log was going to completely burn; therefore, there wouldn't be any ashes left to measure. B. He didn't set a time limit on how long he was going to let the log burn. C. He didn't measure the weight of the log before it was burned. D. He didn't have a partner there in order to verify the results.

What volume of 0.194 MNa3PO4 solution is necessary to completely react with 85.5 mL of 0.109 MCuCl2 ?
ira [324]

Answer:

35.9 ml

Explanation:

Start with the balanced equation:

3CuCl2(aq)+2Na3PO4(aq)→Cu3(PO4)2(s)+6NaCl(aq)

This tells us that 3 moles of CuCI2 react with 2 moles Na3PO4-

∴  1 mole CuCl2 will react with 2/3 moles Na3PO4

We know that concentration = moles/volume i.e:

c= n/v

∴n=c×v

∴nCuCl2=0.107×91.01000=9.737×10−3

I divided by 1000 to convert ml to L

∴nNa3PO4=9.737×10−3×23=6.491×10−3

v=nc=6.491×10−30.181=35.86×10−3L

∴v=35.86ml

What is the formula of the chromium(iii) complex that contains two ammonia and four thiocyanate (scn−) ligands?
Nonamiya [84]
Answer is: formula of the complex is [Cr(NH₃)₂(SCN)₄<span>]</span>⁻<span>.
This complex has negative charge (-1) because chromium (central atom or metal) has oxidation number +3, first ligand ammonia has neutral charge and second ligand thiocyanate has negative oxidation number -1:
+3 + 2</span>·0 + 4·(-1) = -1.

Answer:

The false statement is d Avery,Macleod and McCarty showed that DNA is the genetic information of cells and RNA is the genetic information in the viruses .

Explanation:

Avery,Macleod and MacCarty showed that DNA is the genetic material of the cell.

     On the other hand Fraenkel, Conrat and Sanger carried out their experiment on tobacco mosaic virus to prove that RNA act as genetic material in some viruses.
