A chemical bond<span> is a lasting attraction between </span>atoms<span> that enables the formation of </span>chemical compounds<span>. The bond may result from the </span>electrostatic force<span> of attraction between atoms with opposite charges, or through the sharing of electrons as in the </span>covalent bonds<span>. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or </span>ionic bonds<span> and "weak bonds" such as </span>Dipole-dipole interaction<span>, the </span>London dispersion force<span> and </span>hydrogen bonding<span>.</span>
Answer:
a. 2x + 4
Step-by-step explanation:
Four more than twice a number
Let x = unknown number
Four more than twice of x
Twice of x can be written as 2x
Four more than 2x
Four more can be written as + 4
We get 2x + 4
