One hundred grams of water is saturated with NH CI at
Pepsi [2]

Answer:

  • About 18 g of NH₄Cl will precipitate.

Explanation:

The <em>table G</em> is the graph of the solubility curves for several solutes which is attached.

The second picture identifies the solubilities for the  NH₄Cl at 50ºC and 10ºC.

The solubility of NH₄Cl at 50ºC is about 52 g/ 100 g of water.

The solubility of NH₄Cl at 10ºC is about 34 g / 100 g of water.

Then, at 50ºC 100 g of water saturated with NH₄Cl contains about 52 g of NH₄Cl and 100 g of water saturated with NH₄Cl contains 34 g of NH₄Cl.

The difference, 52g - 34 g of NH₄Cl shall precipitate:

          52 g - 34 g = 18g ← answer

Covert from scientific notation<br> 1.3 x 10¹²=
Lady_Fox [76]

Answer:

1,300,000,000,000

Explanation:

1.3 x 10^12

We want to convert this from scientific notation.

Tip: in scientific notation the exponent tells you how many place you move the decimal point over. If the exponent is negative you move the decimal point to the left. Ex. For, 4.1 x 10^-8, we would move the decimal point over 8 times to the left to get .00000041. When the exponent is positive we move over to the right. Ex. For, 7.6 x 10^7 we would move the decimal point over 7 times to the right to get 76,000,000

So to convert 1.3 x 10^12 we simply move over the decimal point over 12 times to the right.

1.3 x 10^12 ------> 1,300,000,000,000

Our answer is 1,300,000,000,000

A breathing mixture used by deep-sea divers contains helium, oxygen, and carbon dioxide. What is the partial pressure of oxygen
Kay [80]
Answer is: pressure of oxygen is 31,3 kPa.
The total pressure<span> of an ideal gas mixture is the sum of the </span>partial pressures<span> of the gases in the mixture.
p(mixture) = p(helium) + p(oxygen) + p(carbon dioxide).
p(oxygen) = p(mixture) - (p(helium) + p(carbon dioxide)).
p(oxygen) = 101,4 kPa - (68,7 kPa + 1,4 kPa).
p(oxygen) = 101,4 kPa - 70,1 kPa.
p(oxygen) = 31,3 kPa.

What is the effect of thermal energy on the atoms/molecules in a sample of matter?​
Anestetic [448]

Answer:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
