Find an equivalent fraction for the decimal number. in your final answer, include all of your work. 0.

901/1000

Explanation:

Given the decimal 0.901, to find the equivalent fraction, we will first locate the decimal point and then count the digits after the decimal point which gives 3 numbers (901). To convert the decimal to fraction, we place 1 at the denominator just below the decimal point and then add '3 zeros' to make 1000. Amount is zero's added is dependent on the amount of digits present after the decimal point. for this decimal number, the number of digits are 3 hence the reason for the '3 zeros'.

Therefore the equivalent fraction for the decimal 0.901 is 901/1000.

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.
