Answer:
5) Plant; 6) Heat; 7) never heard of chemosynthesis, sorry :(
Explanation:
A plant is the only thing in an ecosystem that uses photosyenthesis. This includes trees, algea, and grass.
80% of energy is lost as heat used in order to keep the animal warm.
I am really sorry I couldn’t help with 7!
Answer:
B. Bohr’s model electrons cannot exist between orbits, but in the electron cloud model, the location of the electrons cannot be predicted.
AND
C. The modern model explains all available data about atoms; Bohr’s model does not.

The answers are right on Edge. :)
Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.
Answer:
The mole fraction of benzene and toluene in solution containing mole fraction of benzene and toluene in solution containing is 45.9%
Explanation:
don't worry
its is correct!
HCl is a polar molecule with the hydrogen part being partial positive while the chlorine end being partial negative. This is because hydrogen has an electronegativity of 2.1, and chlorine has an electronegativity of 3.0. This means that chlorine attracted most of the electron cloud of molecule hence is the negative dipole, The dipole moment of HCl is 1.08 D (debyes). A Debye is equal to 3.34 x 10-30 coulomb-meters (C-m). The charge of each molecule is o.176+ for H and 0.176- for the Cl
