NaCl can be decomposed by electrolysis
Na, Cl2 and K are in the simplest form and they cannot be decomposed
Using the atomic weights, K = 39, O=16 so KO2= 39+32=71. So K=39/71= 0.549 of KO2 and O2=32=0.45KO2 and O2=8g and 0.45KO2=8g so KO2=8/0.45=17.77g. So to check, K=0.549 x 17.77g=9.76 and so K+O2= 9.76+8g=17.76.
C.)Cool air near the surface forms high-pressure areas; warm air forms low-pressure areas.
Explanation:
The relationship between air temperature and high and low pressure air is such that cool air near the surface forms high-pressure areas and warm air forms low pressure areas.
- Cool air is closer to the surface because it has low kinetic energy to move. It is denser.
- Warm air rises sharply away from the ground surface.
- They form low pressure areas and their molecules are wide apart due to their high kinetic energy. The air is less dense.
