B) a new element is synthesized in a particle accelerator. Basic development.
C) a computer is redesigned to increase the speed of the computer. Technological development.
Explanation:
The correct answer is BI₃
Lewis acid refers to a compound that could accept a pair of electrons, while Lewis base refers to a compound that could donate a pair of electrons.
In the mentioned reaction,
In NH₃, nitrogen exhibits a lone pair of electrons and is functioning as a Lewis base. In BI₃, the boron is deficient for an electron pair, thus in order to complete its octet it functions as a Lewis acid.
In chemistry he have to study atoms,molecules,etc.as u know these all are very small in their size.it is very hard to mesure the mass of a singal atom so scientist developed a new system that we call mole system.
<span>1 mole = 6.022 * 10^23.it is like 1 dozen = 12,1 grros =144 </span>
<span>2).11.1 MOLE of O2 is required. </span>
<span>3).69 g of O2 is used </span>
<span>4).239.14 g of CO2 & 146.73 g of H2O is made.</span>
