<span>Physical properties are easier to observe than chemical properties as they include characteristics such as color, texture, etc. while to observe chemical properties, testing must be done of the substance such as heating the substance up to determine at what temperature it will combust</span>
You should see a white precipitate form.
The chemical equation is
AgNO₃(aq) + NaCl(aq) → AgCl(s) + NaNO₃
Answer:
1363.2 kilocalories
Explanation:
Heat up the ice ==> melt the ice to water ==> heat the water ==> vaporize the water to steam ==> heat the stem 52 degrees to 152
1.81 kg * (spec heat of ice * 19 +* heat of fusion of water + specific heat of water *100 + heat of vaporization of water + specific heat of steam* 52)
1810 g * ( .50 cal/g -C * 19 C + 79.7 cal / g + 1 cal/g-C *100C + 539 cal/g + .48 cal/g * 52 C ) =<u> 1 363 219.6 calories</u>

Answer:
HCl conc.= 6.0mol/L
Explanation:
From the dissociation of HCl= 1 mole H+ and 1mol Cl-, which is equivalent stoichiometrically in concentration to that of 1 mol HCl,
