The answer is ; Tectonic plates

The plates sit above the ‘plastic’ mantle and move due to the convection currents in the underlying mantle. There are approximately 7 major tectonic plates of the lithosphere. Where some of these plates collide is called a convergence/ destructive boundary while where they move away from each other is called a divergent/constructive boundary.

Use the van der waals equation to calculate the pressure exerted by 1.335 mol of cl2 in a volume of 4.920 l at a temperature of
nika2105 [10]
<span>Van der waal or ideal eqn is given by PV = NRT; P = NRT/ V. Where N = 1.335 is the number of moles. T = 272K is temperature. V = 4.920L is the volume. And R = 0.08205L. Substiting the values into the eqn; we have, P = (1.331* 0.08205 * 272)/ 4.920 = 29.7047/ 4.920 = 6.03atm.</span>

nuclear reactions can be written out in equation form with information about the nuclei that are produced. in one to two sentenc
Umnica [9.8K]

Nuclear fusion involves the combination of two light nuclei to form a heavier nucleus with emission of energy.

A nuclear reaction equation is a representation of the change that takes place as one nucleus is converted to another. A nuclear transformation could be any of the following;

  • Nuclear fission
  • Nuclear fusion
  • Transmutation

We can know that a nuclear fusion is taking place when two nuclei come together to form a larger nucleus and emit energy. I would identify a nuclear fusion when;

  • Two light atom combine to give a larger nucleus
  • Tremendous energy is produced

What mass of agno3 can be dissolved in 250g of water at 20°c?
Mice21 [21]
Hello there,

You should know the <span>solubility of AgNO3 in water at 20°C equals to 2220 g/L.

So we can say that in 1 L of water, 2220 g of AgNO3 can be dissolve.

Now you should know 1L = 1000g.

Which means 1000 g of water can dissolve 2220 g of AgNO3.

Therefore :

</span>250 g<span> --> x
1000 g --> 2220 g

So : </span>x = \frac{250*2220}{1000} =  \frac{555000}{1000}= 555g.

In short, 555g of AgNO3 can be dissolved in 250g of water at 20°C.

Hope this helps !
