Answer: A) Rock formed by...magma or lava
Explanation:
As the question says, igneous rocks are formed from the cooling and solidification of magma or lava.

C.
The solute is dissolved in the solvent
Answer:
A is correct...B and C wrong I believe
Explanation:
So basically the reason A should be correct is because all enzymes do is provide alternative mechanisms for reaction to proceed and in that alternative mechanism the activation energy is lowered allowing the reactions to progress at greater speeds.
So A makes sense because The aerodynamic shape of a car, like an enzyme, does not supply energy to the car, but it can make it easier for the car to move (basically like an enzyme the car's shape is allowing the car to move faster... enzymes are not consumed in a reaction; they simply help it to occur.)
B is not correct because enzymes do not provide energy for reaction to occur. All they provide is an alternate mechanism where the activation energy is lowered so the reactions can occur at greater rate.
C is not correct because some reactions can occur without enzymes its just that they will occur at a much slower speed.
Hope this helps! I think this should be correct plz double check with your friends.
The correct answer is C-C bond has the longest covalent bond distance.
However, the corresponding CC bonds are weaker than the CN double and triple bonds. The strength of the C-N single bond is not always affected by its ionic or polar nature. Polar bonds like the F-H or O-H bonds, for instance, are among the strongest single bonds. The distance between the nuclei of the two atoms connected by a bond is known as the bond length. we may say that the total of the covalent radii of two bound atoms is nearly equivalent to the bond length. The angstrom unit serves as the standard unit of measurement for bond length. Several methods, including rotational spectroscopy, X-ray diffraction, and neutron diffraction, can be used to measure the bond length.
