how did u get the enthalpy of carbon, -393.51 kJ/mol, ?

Ques: If 6g of pure carbon is completely burned, what mass of carbon must be burned to furnish 39.3 kj of heat? For this ques, the equation would be C + O_2 \xrightarrow~ C O_2 well, iam stuck after this

What would be the shapes of these molecules? I drew them out but I couldn't still figure out the exact shape names a. SeO_{3} b. HClO_{2} c. NO_{2}^{-} d.ClF_{5}

would nitrogen form NCl3 and NCl5 as PCl3 and PCl5?

Because the rotation of the Earth about it's own axis, a point on the equator experiences a centripetal acceleration of 0.034m/s(square). While a point at any of the poles experiences no such acceleration. 1) Show that the true weight of an object (the gravitational force of the object) at...

Hello, http://img219.exs.cx/img219/9273/lastscan19rc.jpg Can anybody explain how to startup the questions? Thank you!

im only doing upto fourth energy level. Just to make sure, since this is not an Earth based ordering, 5s, 5p, and 6s wouldn't come..right? thanks alot

Hello, Sorry about this and please don't think I m a lazy guy who is posting an assinment that is due tomorrow. I m scanning it and posting this because these questions do not involve numbers but require reasoning in which i m bad at. I m currenly taking a Physics 2nd year distance ed course...

ok, so this is how would the electron config. look like..? 1s^{3}2s^{3}2p^{6}3s^{3}3p^{6}4s^{3}3d^{9}4p^{6}4d^{9}4f^{12}

the p shell would have maximum of 7 electrons? d > 10 electrons f > 15 ?

n=0\rightarrow \mbox{impossible} n=1\rightarrow l=0\rightarrow m_{l}=0 1s n=2\rightarrow l=1\rightarrow m_{l}=0,1 2p n=2\rightarrow l=0\rightarrow m_{l}=0 2s n=3\rightarrow l=2\rightarrow m_{l}=0,1,2 3d n=3\rightarrow l=1\rightarrow m_{l}=0,1 3p n=3\rightarrow...

im not sure if that helps.. In our planet Earth , there are only 2 spin states which are +1/2 and -1/2 and the magnetic quantum numbers are -L to +L (postive to negative) Now, if there were an additional spin state which is 0 in another planet and the magnetic quantum numbers are only...

In a planet, if the spin numbers were +1/2, 0 , and -1/2 and their magnetic quantum numbers take the values 0, 1, 2,...L ( Everything else including the ordering and naming of the orbits are same except the spin numbers and the magnetic quantum numbers as provided above.) how would the...

hello tutor.. thanku for ur help...ive got it!

i agree...but I am not allowed to use Hoffmann degradation or "trans-acyl one mixture and trans-aminate the other." im only allowed to use halogenation, hydration, hydrohalogenation, addition, substitution, and combustion...just the basic stuff...im sry i didnt mention it before so..if u...
