Draw an electron-dot structure for the CH3+ molecule and answer the following questions. 1. There are a total of valence electron(s) in this molecule. 2. Does this molecule have any multiple bonds? 3. Does this molecule have resonance structures? 4. There are lone-pair electrons in this molecule. 5. There are electron group(s) (or charge clouds) around the central atom. 6. The molecular geometry of this molecule is . 7. The formal charge is for hydrogen atoms and is for the carbon atom.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

the ratio of the conjugate base to the acid required to attain the desired ph.

what are the statements

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
