A combination reaction<span> is a </span>reaction<span> in which two reactants combine to form one product. It is also called a synthesis reaction. A characteristic to this type of reaction would be that there would always be only one product. Hope this answers the question. Have a nice day. </span>
Water's specific heat capacity is 4200 J/Kg°C
95-28=67
72.5grams in kg is 0.0725kg
Energy = 67×0.0725×4200
Energy = 20,401.5 J or 20.4015 kJ
Photosynthesis takes place in the chloroplasts, that is why the chloroplasts is green. The function of this organelles is to create energy into sugar from the sunlight.
Color change , temp. change ,if a solid forms , umm there's probably more but that's all I remember
Answer:
Some of the calcium carbonate remained stuck to the side of the glassware after filtering
Some of the calcium carbonate spilled when measuring its mass
Explanation:
The percent yield is obtained from;
Actual yield/Theoretical yield * 100
Usually, the actual yield is less than the theoretical yield thereby making the percent yield less than 100%.
In the case of this particular reaction; when some calcium carbonate remains stuck on the glassware or some calcium carbonate is spilled during weighing, the actual yield of product obtained from the reaction becomes less than the theoretical or calculated yield hence the percent yield becomes less than 100%.
