Determine the boiling point of water at 620 mm Hg?
AfilCa [17]
For example, at sea level the atmospheric pressure is 760 mm Hg<span> (also expressed as 760 torr, 101325 Pa, 101.3 kPa, 1013.25 mbar or 14.696 psi) and pure </span>water<span> boils at 100°C. However, in Calgary (approx. 1050m above sea level) the atmospheric pressure is approximately 670 </span>mm Hg<span>, and </span>water<span> boils at about 96.6°C.</span>

If the dosage for a medication is 225mg/lb, how many grams should a 25-lb child be given?
Oksanka [162]

Answer:

5.625 grams

Explanation:

Start your equation with what you have been given.  Place the units you need in your answer on the right side of the equal sign.

225mg

-----------   X  -----------   X ------------- =   ?   g

   lb

Now start to fill in your equation and use a conversions to get rid of the units you don't want.  Convert mg into grams first.  The child's weight (25 lb) is placed over 1 just to get the equation lined up properly so you can see how the units cancel out.

225 mg                 1 g                  25 lb            5.625 g

---------------   X   ---------------  X   -------------  =   ---------------

   lb                    1000 mg                 1                  1

The lb on the top and bottom cancel each other out and you are left with just grams.  Even though it is over one, that is the same at just 5.625 grams.

Explain the process of how James Chadwick found the neutron.
Andrews [41]

Answer:

Discovery of neutron

Explanation:

Until 1932, the atom was believed to be composed of a positively charged nucleus surrounded by negatively charged electrons, after successful discovery of electron by J.J. Thompson and proton by  Ernest Rutherford.

In 1932, James Chadwick bombarded beryllium atoms with alpha particles.

As Chadwick had previously seen in experiment conducted by Frédéric and Irène Joliot-Curie, they had bombarded a sample of beryllium with alpha radiation.

Chadwick repeated the experiment and observed an unknown radiation, this showed no deflection what-so-ever.

He repeated this experiment by bombarding other materials, like helium, nitrogen and lithium,

Finally, Chadwick found that this radiation was composed of particles with a neutral electrical charge and had approximate mass of a proton.

This particle was then known as the neutron.
