The parts that are either directly or indirectly related to each other in a system are known as what? A) the flow

B) the boundary

C) the components

D) the input

C) the components

Explanation:

The term component is referred to as the distinctively recognizable part, piece, of a system that is required to complete a function, in that particular system. Moreover, it carries out a distinguishable and necessary function in the operation of a specific system.  For example, a computer has a number of components that make it whole, and the most essential of them is the Central Processing Unit.

i think a, hope it .

explanation:

answer: the enthalpy of the overall chemical reaction is +87.88 kj or +88 kj.

according to hess's law, the overall enthalpy of a reaction is the difference between the sum of enthalpy values of all the products and the sum of enthalpy values of all the reactants.

δh(reaction) = ∑nδh(products) - ∑nδh(reactants)

δh(reaction) = [δh +δh] - [δh]

δh(reaction) = [1(-287.02) + 1(0) ] - [1(-374.9)] kj = +87.88 kj

here, δh (pcl3) = -287.02 kj, δh(cl2) = 0, δh(pcl5) = -374.9 kj

therefore, enthalpy of the overall reaction is +87.88 kj or +88 kj.
