Why is Dalton's Gas Law a problem for people who visit high altitudes?
sergey [27]
Dalton’s law states that any given time the percentage of each of these (toxic?) gasses in the air we breathe it’s contribution.

People who ascend high altitudes experience Delton’s law when they try to breathe. Oxygen’s pressure decreases a total atmospheric pressure decreases in accordance with Dalton’s law.

A company is testing drinking water and wants to ensure that ca content is below 155 ppm. What is the maximum amount of Ca that
BabaBlast [244]

Answer:

138 mg

Explanation:

A company is testing drinking water and wants to ensure that Ca content is below 155 ppm (= 155 mg/kg), that is, <em>155 milligrams of calcium per kilogram of drinking water</em>. We need to find the maximum amount of calcium in 890 g of drinking water.

Step 1: Convert the mass of drinking water to kilograms.

We will use the relation 1 kg = 1000 g.

890g \times \frac{1kg}{1000g} =0.890kg

Step 2: Calculate the maximum amount of calcium in 0.890 kg of drinking water

0.890gH_2O \times \frac{155mgCa}{1kgH_2O} = 138mgCa

Answer:
               Cp  =  0.093 J.g⁻¹.°C⁻¹
Solution:

The equation used for this problem is as follow,

                                                  Q  =  m Cp ΔT   ----- (1)

Where;
            Q  =  Heat  =  300 J

            m  =  mass  =  267 g

            Cp  =  Specific Heat Capacity  =  ??

            ΔT  =  Change in Temperature  =  12 °C

Solving eq. 1 for Cp,

                                 Cp  =  Q / m ΔT


Putting values,
                                 Cp  =  300 J / (267 g × 12 °C)

                                 Cp  =  0.093 J.g⁻¹.°C⁻¹

Is the dissolution of borax in water a temperature dependent reaction or is it spontaneous at all temperatures at which water is
enot [183]

The dissolution of borax in water is a temperature dependent reaction. With the higher temperature, the salt dissolve quickly.

<h3>What is borax?</h3>

Borax is the hydrate salt of boric acid. It is white and widely used in cleaning and in laundry  detergent.

Borax is a salt that will dissolve in water at almost any temperature, with the exception of steam and ice.

However, as with any salt, the higher the temperature, the faster the salt dissolves, so speed is dependent on temperature. It will dissolve in cold water, but it will take longer.

Thus, the dissolution of borax in water is a temperature dependent reaction.
