Answer:
A leaf needs carbon dioxide and water for photosynthesis. ... For carbon dioxide to enter, the stomata on the surface of the leaf must be open. As you have seen, transpiration draws water from the roots into the leaf mesophyll.
I hope this helps you :)
Answer:
The molecular formula is C2H2Br4
Explanation:
Molar Mass of CHBr2 = 12 + 1 + (2x80) = 12 + 1 + 160 = 173
The molecular formula = n x empirical formula
Molar Mass of the compound = 345.6
Empirical formula = CHBr2
n(CHBr2) = 345.6
n x 173 = 345.6
n = 345.6/173 = 2
Therefore the molecular formula is n(CHBr2) = 2(CHBr2) = C2H2Br4
The answer is "More Stable."
Concave is not a type of mechanical wave because it doesn’t need a medium for propagation.
