William adds two values, following the rules for using significant figures in computations. He should write the sum of these two numbers by using
the same number of decimal places as the least precise value.
the same number of decimal places as the most precise value.
O a range of the number of significant figures in the two values.
O an average of the number of significant figures in the two values.

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.

The velocity would be 2
