Im answering question 2
Because it increases the kinetic energy of reactants and so the frequency of collision between reactants. Thus, provided the temperature is not too high to lead to denaturation of reactants, increase in temperature increases the rate of reaction
And for ques. 7:
It gets affected when gaseous reactants in which products formed have less volume than reactants, so increase in pressure increases the rate of reaction
The answer is going to be NaCl<span>, when dissolved in a polar solvent, dissociates (splits apart) completely to form </span>sodium ions<span> and </span>chloride ions<span>.
ACIDS<BASES<AND SALTS ARE ALWAYS ELECTROLYTE
</span>
A polar covalent bond is a covalent bond in
which the atoms have an unequal attraction for
electrons and so the sharing is unequal. ... The
atom with the greater electronegativity acquires
a partial negative charge, while the atom with
the lesser electronegativity acquires a partial
positive charge.
here you go
<span>Both are composed of two elements (that means binary).
Ionic is composed of two ions, metallic cation-positive ions, and nonmetallic anion - negative ions. For example NaCl (sodium-chloride).
Molecular compounds are composed of two nonmetallic elements. For example HCl (hydrochloric acid).</span>
