Answer:

No.

Explanation:

Pb (lead) is higher on the activity series than Cu (copper). Since Cu is lower, no reaction forms.

Round off the following measurement to three significant digits: 3255 mL. (a) 325 mL (b) 326 mL (c) 3250 mL (D) 3260 mL (e) none of the above

Answers

The answer is B. If you round it correctly you would get 326 ml and this number happens to have three significant digits.

Final answer:

To round off the measurement 3255 mL to three significant digits, the correct answer is (c) 3250 mL.

Explanation:

To round off a measurement to three significant digits, we look at the digit to the right of the third significant digit. If this digit is 5 or greater, we round up. If it is less than 5, we round down. In the given measurement of 3255 mL, the digit to the right of the third significant digit is 5, so we round up. Therefore, the correct answer is (c) 3250 mL.

Name two metals that do not always lose the same number of electrons

Answers

Copper and Iron are two metals that can lose different numbers when they react with another molecule.

What are transition metals?

  • These are the metals that have variable valence electrons and form many-colored co-ordinate compounds.

  • The transition metals have variable oxidation state means they can lose different numbers of electrons while making a bond.

  • The variable oxidation state is due to the electronic configuration in which they have partially filled d- block which allows them to have variable oxidation numbers.

Therefore, copper and Iron are two metals that can lose different numbers when they react with another molecule.

Write the balanced equation for the reaction of aqueous Pb(ClO3)2 with aqueous NaI.

Answers

 The  balanced  equation for the  reaction  of aqueous Pb(ClO3)2  with aqueous NaI   is as below

Pb(ClO3)2(aq)  + 2NaI(aq)  → PbI2(s) +  2 NaClO3(aq)

    Explanation

 from the equation  above   1mole  of lead(ii) chlorate Pb(ClO3)2   react   with    2 moles  of sodium  iodide  to form   1 moles  of lead(ii)  iodide( PbI2)  and  2  moles  of sodium chlorate NaClO3.  
Pb(ClO_3)_(2(aq))+2NaI_((aq))=PbI_(2(s))+2NaClO_(3(aq))

Compounds that do not conduct an electric current in either aqueous solution or when molten are referred to as _____.a. electrolyte
b. nonelectrolyte
c. not listed
d. ionic

Answers

The answer is B. Nonelectrolyte. Nonelectrolytes are substances that do not dissociate into ions when dissolved in a solution. In some cases, they dissociate into molecules rather than ions. They are usually polar covalent substances such as sucrose (C12H22O11). Nonelectrolytes are considered to be poor conductors of electricity.
