Explanation:</h3>
- Photosynthesis refers to the process that takes place in green plants and some algae.
- During the process, water and carbon dioxide are converted to nutrients or organic compounds using energy from sunlight.
- The process takes place in the chloroplast on the leaves of green plants.
- The water used during photosynthesis comes from the soil and then transported by xylem tissue to the leaves where the process takes place.
- Carbon dioxide enters the leaves through the stomata which are the sites for gaseous exchange.
- Sunlight is trapped by green pigments on the leaves known as chlorophyll.
Answer:
electronegativity increases
1) Calcium carbonate contains 40.0% calcium by weight.
M(CaCO₃)=100.1 g/mol
M(Ca)=40.1 g/mol
w(Ca)=40.1/100.1=0.400 (40.0%)!
2) Mass fraction of this is excessive data.
3) The solution is:
m(Ca)=1.2 g
m(CaCO₃)=M(CaCO₃)*m(Ca)/M(Ca)
m(CaCO₃)=100.1g/mol*1.2g/40.1g/mol=3.0 g
