En la siguiente tabla se presentan dos propiedades físicas de algunos contaminantes orgánicos que se encontraron en una muestra de agua proveniente de un pozo. La muestra de agua es analizada y se corrobora que este tipo de sustancias pueden llegar a ser tóxicas para los seres humanos y puede afectar considerablemente su salud por lo que, una alternativa de solución para eliminar estos contaminantes sería: * Imagen sin título
A. filtrar el agua antes de consumirla.
B. evaporar el agua hasta que no exista ningún residuo.
C. calentar el agua hasta alcanzar su punto de ebullición.
D. destilar las sustancias hasta alcanzar los 78◦C

Compare the valence electron configuration of the nobles gas elements seen here. what statement is correct?

Which statement best describes the relationship between period and frequency of light waves? a) in wave b the period increases and the frequency decreases from wave a. b) in wave a the period increases and the frequency decreases from wave b. c) in wave b the period is shorter and the frequency is greater than in wave a. d) in wave a the period is shorter and the frequency is greater than in wave b.

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
