Franklin was performing an experiment by combining hydrochloric acid and sodium hydroxide. He measured the mass of his reactant

materials to be 35g. The reaction resulted in the production of salt and water. He reported that his products weighed 32g.

Answer:

<u></u>

  • <u><em>B) an error occurred, the mass of the reactants should equal the mass of the products. </em></u>

<u><em /></u>

Explanation:

The answer choices are:

  • <em>A) no error occurred, some of the products are always lost as heat.</em>

<em />

  • <em>B) an error occurred, the mass of the reactants should equal the mass of the products. </em>

<em />

  • <em>C) an error occurred, the products should weigh more than the reactants. </em>

<em />

  • <em>D) no error occurred, water is not weighed when determining the weight of the products.</em>

<h2>Solution</h2>

The basis to answer this question is the law of conservation of mass.

Any chemical reaction satisfies the law of conservation of mass: mass cannot be either created nor destroyed, so, always, <em>the mass of the reactants equal the mass of the products.</em>

Thus, since he measured the mass of his reactant materials to be 35g and he reported that his products weighed 32g, his data are in clear contradiction of the law of conservation of mass. So, there is an error in his results: <em>the mass of the reactants should equal the mass of the products. </em>

What is the basic definition of carbohydrates
ikadub [295]

Carbohydrates are substances that are found in foods such as bread and pasta, which provide the body with heat and energy. Chemically, carbohydrates are made of three kinds of elements namely carbon , hydrogen and oxygen.

Carbohydrates are separated into two main categories, simple carbohydrates and complex carbohydrates.  

Simple carbohydrates are those that contain one or two sugar molecules linked together. Complex carbohydrates are those that contain  three or more sugar molecules linked together. In some cases these chains can contain hundreds of sugar molecules.

What is the wavelength of radiation that has a frequency
White raven [17]

Answer:

\lambda = \frac{c}{\nu}

Explanation:

The wavelenght of  a radiation is inversely proportional to its frequency. It can be estimated by the following formula:

\lambda = \frac{c}{\nu}

Where:

  • \lambda is the wavelenght
  • \nu is the frequency
  • c is the speed of light (arroung 300000 km/s)
