A covalent bond is a bond between 2 non-metals (sharing of electrons between atoms), where ionic is between a metal and a non-metal (the transfer of electrons). Standard covalent bonds are usually weaker then ionic bonds.
Covalent - Hydrogen + Chlorine = Hydrogen Chloride (HCl)
Ionic - Sodium + Chlorine = Sodium Chloride (NaCl)
It causes a much more gradual decrease in hardness with position from the quenched end.The presence of alloying elements (other than carbon) does not influence on the shape of a hardenability curve.It causes a much more rapid decrease in hardness with position from the quenched end.
Answer:
The third option, Light intensity has an impact on the rate of photosynthesis.
Explanation:
Light is a limiting factor at low intensity. Thus the rate of photosynthesis increases with an increase in light intensity. High light intensities affect the rate of photosynthesis. It increases the temperature of the leaves. Therefore, rate of transpiration increases
A is the correct answer but if that’s not the right answer d is
