Hexane has a higher vapor pressure
Explanation:
Generally, heat flows from a hot environment to a cold (lesser temperature) environment. In this case, the soup is the hot environment and the air is the cold temperature.
Heat would continue to flow from one environment to another until thermal equilibrium is reached. At this thermal equilibrium, both environments would have the same temperature.
<span>True Solution is a homogeneous mixture of two
or more substances in which substance dissolved (solute) in solvent has
the particle size of less than 10-9 m or 1 nm. Simple solution of sugar in water is an example of true solution.</span>
Answer:
m=4 g Ca
M=ArCa+ArO=56 g/mol
Ca+O2-2CaO
nCa= m/M= 4/40=0.1 moles of Ca
the ratio of moles: 1 mole Ca:2 moles CaO
0.1 moles Ca =0.2 moles CaO
n=m/M
m=n×M
m=0.2×56=11.2 g CaO
23. Enzyme A, as the temperature increases, the rate of reaction goes down. However, Enzyme B as the temperature goes up the reaction goes up.
24. Enzyme B is more active in a human cell, the reaction is what you want and everytime the temperature goes up in enzyme B the reaction goes up.
