PLEASE HELP PLEASE IM BEGGING U Answer the question below if the molar mass of P is 31g/mol and the molar
mass of Cl is 35.5g/mol.
How much heat will be released when
5.5 g of chlorine reacts with excess
phosphorus according to the following
equation.
2P + 3Cl2 + 2PCIs AH = -886 kJ

Esign techniques and materials that reduce the negative environmental impact of a structure are referred to as

Choose an equation that represents an enzyme-catalyzed reaction. (a) enzyme + substrate → enzyme-substrate complex (b) enzyme + substrate ←−→ enzyme + products (c) enzyme + substrate ←−→ enzyme-substrate complex → enzyme + products (d) enzyme + substrate ←−→ enzyme-substrate complex → enzyme-substrate complex + products

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 1.5. subtract the electronegativities for the following pairs of elements and predict whether they form a covalent bond. electronegativity difference of c and c: ionic covalent electronegativity difference of mg and cl: ionic covalent
