14 g is the solubility per 100 g water, since it is difficult to read the graph.
<span>Then, in 130 g H20 the solubility would be 14 g KNO3/100 g H2O x 130 g H2O = 18 g KNO3 </span>
<span>The question asks how much crystallizes. </span>
<span>Initial 34.0 g minus 18.0 g still dissolved = 16.0 g crystallizes.</span>
La densidad del metal disminuye a medida que se calienta . Piense en el agua . Cuando hace frío , se convierte en hielo , lo cual es muy densa . Cuando hace calor , se evapora en gas , que no es denso.
<span>Espero que esto no es confuso , yo no soy un hablante nativo de español .</span>
Answer: e. 37
Explanation:
When two vectors are added, the maximum and minimum posible values, happen when both vectors are aligned each other.
If both vectors aim in the same direction, the maximum value is just the arithmetic sum of their lengths, in this case, 60.
If they aim in opposite direction, the resultant is the substraction of their magnitudes, which yields 20.
Any other posible value (depending on the angle between vectors, which can span from 0º to 180º) must be between those values.
So, the only choice that fits within this interval, is 37.
As we know that speed of sound is
frequency of sound is
now we know that frequency of sound and speed of sound is related to each other by the following formula
<em>so wavelength of sound is 25 cm or 0.25 m</em>
