Yes because an object has kinetic energy when its moving only, and has only potential energy when velocity is zero and there is height but for your statement to be true,the object has to have some height so there can be potential which can become kinetic energy

A 25.888 g sample of aqueous waste leaving a fertilizer manufacturer contains ammonia. The sample is diluted with 73.464 g of wa
brilliants [131]

Answer:

Weight % of NH₃ in the aqueous waste  = 2.001 %

Explanation:

The chemical equation for the reaction

\\\\NH_3} + HCl -----> NH_4Cl

Moles of HCl = Molarity × Volume

= 0.1039 × 31.89 mL × \frac{1 \  L}{1000 \ mL}

= 0.0033 mole

Total mass of original sample = 25.888 g + 73.464 g

= 99.352 g

Total HCl taken for assay = \frac{10.762 \ g}{99.352 \ g}

= 0.1083 g

Moles of NH₃ = \frac{0.0033 \  mol}{0.1083}

= 0.03047 moles

Mass of NH₃ = number of  moles × molar mass

Mass of NH₃ = 0.03047 moles × 17 g

Mass of NH₃  = 0.51799

Weight % of NH₃  = \frac{0.51799 \ g}{25.888 \ g} * 100%%

Weight % of NH₃ in the aqueous waste  = 2.001 %
