Answer:

1.4% NaCl solution is Hypertonic

Explanation:

A hypertonic solution is type of solution that has a greater concentration of solutes (substance given in a solution) on the outside of a cell when compared with the inside of a cell.

Any solution of sodium chloride (NaCl) in water with a concentration of NaCl higher than that found in physiological saline (0.9%) is considered to be hypertonic

Perform the following conversions:
kozerog [31]

The temperature in in Celsius is 5826.85 degree Celsius and Fahrenheit is 10520.33.

To express temperature in kelvin and Celsius two different relations are used,  The formula to convert Fahrenheit to Celsius we use the formula T(K) = (T(°F) + 459.67)× 5/9 here T(k) mean temperature in kelvin and T(F) is temperature in Fahrenheit so by putting the given data we get (6100 − 273.15) × 9/5 + 32 = 10520.33°F and so now we obtained the temperature in kelvin so to convert   kelvin to Celsius we use this formula °C=K−273.15, so by putting the given data 6100 − 273.15 = 5826.85°C.Kelvin, Celsius and Fahrenheit are the three units to measure the temperature.

1. Girona y Castellón están separadas 360 km. Un tren sale de Girona hacia Castellón con
Vlad [161]

Answer:

Ambos trenes tardarán 2 horas y 24 minutos en cruzarse.

Explanation:

Dado que el tren que sale de Girona lo hace una hora antes que el que sale de Castellón, y que circula a 108 km/h, al momento en que el tren que parte de Castellón inicia su recorrido la distancia entre ambos trenes, que en principio es de 360 km, se ha reducido a 252 km (360 - 108).

Así, luego de la primer hora de recorrido, ambos trenes se separan por 252 km. A la segunda hora, el tren de Girona ha recorrido otros 108 km, mientras el tren de Castellón ha recorrido 72 km, es decir, en total han acortado otros 180 km, con lo cual la distancia entre ambos ahora es de 72 km (252 - 180).

Ahora, para la última parte del recorrido, se debe dividir el horario. Así, el tren de Girona recorre 108 km en una hora, con lo cual, en 20 minutos, puede recorrer 36 km. A su vez, el tren de Castellón puede recorrer en el mismo tiempo 24 km, con lo cual, tras 2 horas y 20 minutos, la distancia entre ambos es de 12 km (72 - 60).

Para los últimos 12 km, debe dividirse el horario por un número menor. Así, en 4 minutos (60 / 15 = 4), el tren de Girona recorre 7.2 km (108 / 15 = 7.2), mientras que el tren de Castellón recorre 4.8 km (72 / 15 = 4.8). Así, dado que 7.2 + 4.8 es igual a 12, es decir, los km que faltaban para que ambos trenes se cruzaran, el tiempo en el cual ambos trenes tardarán en cruzarse es de 2:24 horas.

In the laboratory, a student dilutes 13.5 mL of a 11.6 M hydroiodic acid solution to a total volume of 100.0 mL. What is the con
igomit [66]

Answer: The concentration of the diluted solution is 1.566M.

Explanation:

The dilution equation is presented as this: M_{s} V_{s} =M_{d} V_{d}.

·M= molarity (labeled as M)

·V= volume (labeled as L)

·s= stock solution (what you started with)

·d= diluted solution (what you have after)

Now that we know what each part of the formula symbolizes, we can plug in our data.

11.6M*13.5mL=M_{d} *100mL

We cannot leave it like this because the volumes must be in Liters, not milliliters. To convert this, we divide the milliliters by 1000.

13.5mL/1000=0.0135L     100mL/1000=0.1L

Now that we have the conversions, let's plug them into the equation.

11.6M*0.0135L=M_{d} *0.1L

The only thing that we need to do now is actually solving the answer.

M_{d} =\frac{11.6M*0.0135L}{0.1L}       M_{d} =1.566M

From the work shown above, the answer is 1.566M.

I hope this helps!! Pls mark brainliest :)
