When 100cm3 of 1.0 molar of sodium hydoxide solution at 200oc was added to 100cm3of1.0 molar of HCL solution at 200oc,then the temperature of HCL rose to 26.8oc.calculate the standard heat of neutralisation?(Given that the specific heat capacity of water is 4.2KJg-1k-1)
At 25 deg C, Heat= -176000 J approx
No. Metals have a relatively low specific heat.
what is the specific heat for copper
Normaly HCl is supplied 35.5% w/w in 2.5 ltr bottles. Its Specific gravity is 1.18 g/ltr. First we convert weight to volume using provided inputs. Now taking all units in CGS g HCl =2500 X1180 =2950 g HCl Further for 35.5 % (means 35.5 in 100) then g HCl =0.355X2950=1047.25 Mole HCl=1047.25/36.5=28.69 Mole Normality and molarity will be same in case of HCl. Molarity=28.69/2.5=11.476 Approx.11.5

find, at the given temperature and pressure, weight of HCL and volume of the same. Find density of HCL by Density of HCL= weight/volume Specific gravity of HCL= density of HCL/density of water
I'm not quite sure if you've formulated your question correctly. Hydrochloric acid, HCl(aq), is what it is, whether cold or hot. When you dilute concentrated HCl the dilution reaction releases a lot of heat (more of it the more conc. the HCl is to begin with). Depending on how much you are diluting may cause the reaction vessel to feel warm (or even hot) to the touch. When you dilute concentrated HCl you should determine how much water it will take and then add the HCl slowly to most of the water required. The water has a high specific heat and can absorb the heat being generated (but you still add the acid slowly). You don't add the water to the conc. HCl. The heat generated can be enough to pretty much instantaneously boil the water and it can splatter in your face (carrying some of the acid with it) causing a severe burn.
HCl and HNO^3 are both acids therefore Neutralisation cannot occur.

Heat rash doesn't need antibiotics.
-55.8 KJ/mol
Be more specific. HCL could be hairy cell leukemia, hydrogren chrloride, hydrochloric acid, etc...
specific heat of lpg
No. The heat of reaction for 50mL of each will be multiplied by 2 for 100mL of each since heat of reaction is really on a per mole product basis, and there will be twice as many moles of both HCl and NaOH in 100mL as in 50mL.
Specific heat has nothing to do with specific volume.
Yes. Zinc + HCl is an exothermic reaction, meaning it gives off heat as a result of reacting.
