please enter the value of lnq that appears in the nernst equation for this cell, zn(s) | zn(no3)2(0.10m) || cu(no3)2(0.10m) | cu(s) .
the q value for the nernst equation can be determined by  the overall reaction of the cell notation. recall that q is the reaction quotient which can be calculated as:determine the overall reaction using the mnemonic for cell notation, abc:step 1. determine the overall reaction and find the anode and cathode. the anode (one being oxidized) and cathode (one being reduced). using the mnemonic, it appears that the anode is zn(s) while the cathode is cu(s).step 2. write the equation where the anode, zn (s), is being oxidized to to zn2+ (from zn(no3)2) and the cathode, cu (s), is produced by reduction of cu2+ (from cu(no3)2zn (s) - anode; cu (s) - cathode zn (s) + cu2+ (aq) → cu (s) + zn2+ (aq)step 3. setup the q expression using the concentration of zn2+ and cu2+ provided. note that (s) and (l) are not included in q or keq expressionsstep 4. plugin q to lnq ln(q) = ln(1) = 0 answer is 0

regards the symbol of tin is 'sn'. hence the correct option is (a) learn more: tin information is below. a=c and b=d
b=d and `anec`
`ab=1 " and "cdne1`
`cd=1" and "ab=ne1`
answer: a
solution: using `a.m.gtg.m,` we have   
 `a+(1)/(b)gt2sqrt((a)/(b))b+(1)/( c )gt2sqrt((b)/( c )),c+(1)/(d)gt2sqrt(( c )/(d))" and "d+(1)/(a)gt2sqrt((d)/(a))`   
 `implies(a+(1)/(b))(b+(1)/( c ))(c+(1)/(d))(d+(1)/(a))gt16`   
 but,`(a+(1)/(b))(b+(1)/( c ))(c+(1)/(d))(d+(1)/(a))=4xx1xx4xx1=16`   
 `:." "a=(1)/(b),b=(1)/( c ),c=(1)/(d)" and "d=(1)/(a)`   
 `implies" "a=(1)/(b)=2,b=(1)/( c )=(1)/(2),c=(1)/(d)=2" and "d=(1)/(a)=(1)/(2)`   
 `implies" "a=2,b=(1)/(2),c=2" and "d=(1)/(2)`   
 `implies" "a=c" and "b=d` <p>concepts and reason</p>
<p>the concept used to solve this problem is the formal charge calculation of the oxygen atoms present in the ozone molecule.</p>
<p>fundamentals</p>
<p>a charge that is assigned to an atom, which is present in the molecule, is represented as a formal charge. in two bonded atoms, a formal charge assumes that the electrons are equally shared between them. the formal charge is calculated using the following formula:</p>
<p>formal charge \(=\mathrm{v}-\mathrm{n}-\frac{\mathrm{b}}{2}\)</p>
<p>here, \(\mathrm{v}\) is the number of valence electrons, \(\mathrm{n}\) is the number of non-bonding electrons and \(\mathrm{b}\) is the number of bonding electrons.</p>
<p> </p>
<p>the structure is as follows:</p>

<p>the marked oxygen atom has 6 valence electrons. it contains 6 non-bonding electrons. the marked oxygen atom is bonded with one oxygen atom. therefore, the bonding electron of oxygen is \(2 .\) substitute the values in a formal charge formula to determine the formal charge of oxygen (marked).</p>

<p>the oxygen atom in the middle has 6 valence electrons and has 2 non-bonding electrons. the central oxygen atom is bonded with 1 double bond and 1 single bond. so, there is a total of 3 bonds containing 6 electrons (bonding electrons). the formal charge of the middle oxygen atom can be determined by substituting the values in a formal charge formula.</p>

<p>the oxygen atom present on the right side contains 6 valence electrons which have 2 non-bonded electrons. the marked oxygen is bonded with 1 double bond with a central oxygen atom. so, the number of bonding electrons is \(4 .\) the formal charge of the corner oxygen atom (right corner) can be determined by substituting the values in the formal charge formula.</p>

for (int i = 0; i <= num\_leds; i++) {

this writes num\_leds+1 pixels, probably not what you wanted.

as the index starts with 0, the highest correct index would be num\_leds-1, not num\_leds. 1) p(x) = 1/x2 + 1 if x ≤ 3 it is clear that x= 3 is included, so you have to use this function.2) loo k at table d, and compare the given information with the data written inside the table. a) 3ag + 4hn03 > 3agno3 + no + 2h2o

b) mno2 + 4hcl > 2h2o + mncl2 + cl2
