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

Answers

Answer 1
Answer:  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.  
Answer 2
Answer: Pb(ClO_3)_(2(aq))+2NaI_((aq))=PbI_(2(s))+2NaClO_(3(aq))

The symbol for hydronium ion concentration is

Answers

The symbol for hydronium ion concentration is H+. There are quite a few relationships between [H+] and [OH−] ions. And because there is a large range of number between 10 to 10-15 M, the pH is used. pH = -log[H+] and pOH = -log[OH−]. In aqueous solutions, [H+ ][OH- ] = 10-14. From here we can derive the values of each concentration.

Answer:

H+

Which statement best describes how a catalyst increases the rate of a reaction?(1) The catalyst provides an alternate reaction pathway with a higher activation energy.
(2) The catalyst provides an alternate reaction pathway with a lower activation energy.
(3) The catalyst provides the same reaction pathway with a higher activation energy.
(4) The catalyst provides the same reaction pathway with a lower activation energy.

Answers

A catalyst works by providing an alternate reaction pathway with a lower activation energy thus allowing more particles of the reactant to overcome the energy barrier and form product per unit of time. (OPTION 2)

What’s the easiest way to add energy to matter

Answers

Answer:

The easiest way is to heat matter which raises its internal energy andso the mass as well. Another possibility is to accelerate matter as in case of protons or heavy ions in the LHC, Protons ,for example , are accelerated to the energies of 6500 GeV which means increase of the rest mass by a factor of almost 7000
