Answer:
D: a new substance
Explanation:
Chemical reaction
A change in matter that produces on or more new substances
The appropriate answer is d. the high specific heat capacity of water. This unique quality of water makes it suitable as an organic solvent. Specific heat capacity is the energy required to change one gram of a substance by one degree. Organic processes need to be carried out at a specific temperature. The high specific heat capacity of water ensures that environmental changes in temperature.
Answer:
The term conclusion best illustrates the given statement.
Explanation:
Conclusion refers to a decision or judgment that can be acquired by reasoning. From the observation mentioned in the given table:
1. The steel, aluminum, and bronze took 27, 45 and 80 seconds to dissolve small section of wax, this signifies that more time will be needed by them to transfer heat to the food while cooking. Thus, food will take more time to cook in them.
2. Copper consumed less time, that is, 15 seconds to melt the section of wax than the other metal pots, which signifies that it is a good conductor of heat than the others. Thus, the copper pot would be good for cooking food briskly.
After evaluating the results and observations in an experiment, the conclusion was made that pots made of copper are best for cooking foods.
Answer:
Law of Conservation of Mass
Explanation:
Balancing chemical equation means that the amount of moles of one atom on side must match the other, which makes sure that no atoms are created nor destroyed in the reaction process.
Answer:
7.52767607125× 10^23 atoms
Explanation:
The Avogadro number/constant indicates that they are 6.022140857 × 10^23 number of units (atoms) in one mole of any substance. Therefore, in this case, ti find the number of atoms in 1.25 moles of calcium acetate, well multiply the two number;
6.022140857 × 10^23 * 1.25 = 7.52767607125× 10^23
