Zinc metal reacts with hydrochloric acid according to the balance...

Question

Zinc metal reacts with hydrochloric acid according to the balanced
equation:
Zn(s) + 2 HCl(aq)¡ZnCl2(aq) + H2( g)
When 0.103 g of Zn(s) is combined with enough HCl to make 50.0
mL of solution in a coffee-cup calorimeter, all of the zinc reacts,
raising the temperature of the solution from 22.5 °C to 23.7 °C.
Find ΔHrxn for this reaction as written. (Use 1.0 g>mL for the density
of the solution and 4.18 J>g # °C as the specific heat capacity.)

Hi everyone. So here we have copper reacting with dilute nitric acid to produce copper nitrate. Fashion dioxide and water. Maybe 0.215 g piece copper metal that's mixed with dilute nitric acid Is 100 ml solution. And the temperature increased from 23°C 25.5°C add to calculate the value of the entropy of the reaction. This reaction we have a density of one grounds. Premier leader In a specific key 4.18 joules per gram times degrees C. These are equation Q M C delta T. Act like the heat absorbed by the solution is what we're looking forward. We also need to find em too. Getting the specific heat 4.18. Those program times degrees Celsius and the temperature change. It's 25.5°C minus 23. You guys Celsius. Just 2.5°C. Now we need to find the mask. I have 100 ml. They have the density with one g per one male. Later then we get 100 grounds. Now we can find the heat absorbed by the solution upper. Que Get 100 g 4.18. Those programs degrees Celsius, That's 2.5°C. Very cute. Get plus 1045 jewels The solution absorbed. 1045 goals of heat The reaction at least. 1,045 goals Of -1045 goals. I have 0.215 grams of copper In one bowl of copper At the Molar mass .55 g of copper. You have 1000 goals In one killer job. Make it 308 0.9. Thanks for watching my video. And I hope it was up for.
