Imagine that you have many U-235 atoms and you fire a neutron at one of them. What do you think will happen?

The correct answer is Release of large amount of heat and radiation.

U-235, which makes up just over 0.7% of natural uranium, is relatively uncommon; uranium is nearly 100 times more frequent than silver.Because uranium-235, one of the radioactive metal's isotopes, is the only naturally occurring isotope capable of supporting a nuclear fission process, radioactive metal is special. Nuclear power facilities, as well as the nuclear reactors that power ships and submarines, can be powered by uranium that has been "enriched" to have a higher proportion of U-235. In nuclear weapons, it can also be applied. Examples of extremely unstable fission fragments produced by uranium-235 fission events caused by neutron absorption include the barium and krypton nuclei. These pieces nearly instantly split into barium-144 and krypton-89 by releasing three neutrons between them.

How much water should be added to 4.3 moles of LiBr to prepare a 2.05 m solution?
arsen [322]

Answer:

2.1 kg of water

Explanation:

Step 1: Given data

  • Moles of lithium bromide (solute): 4.3 moles
  • Molality of the solution (m): 2.05 m (2.05 mol/kg)
  • Mass of water (solvent): ?

Step 2: Calculate the mass of water required

Molality is equal to the moles of solute divided by the kilograms of solvent.

m = moles of solute/kilograms of solvent

kilograms of solvent = moles of solute/m

kilograms of solvent = 4.3 mol /(2.05 mol/kg) = 2.1 kg

frosja888 [35]

Answer:

False

Explanation:

The statement ; Regardless of any concentration of ammonium solution the precipitate of unknown halide after 0.1M AgNO3 will remain is FALSE

This is Because the remaining concentration of AgNO3 is dependent on the solubility of Ag⁺

Write the steps for calculating molar mass.
Marizza181 [45]

Answer:

Explanation:

1) Find number of each of the type of atom that is present in the compound, using the chemical formula .

2) Then multiply number of atoms of each element that is present in the compound with the atomic weight of each of the element

3) Add everything together and add the units (grams/mole ) after the number

Let finds that of water

Chemical formula of water is (H20 )

hydogens atoms= 2

oxygen atom= 1

Atomic weight for Hydrogen= 1

Atomic weight for Oxygen= 16

Total number of atoms of Hydrogen from the formula (H2O)= 2

Total number of atoms of Oxygen from the formula (H2O)= 1

the molar mass=

Hydrogen: ( 2 x 1)= 2

Oxygen: ( 1 x 16)= 16

Add together= (16+2)

= 18

Then add the unit, we have(18 g/mol.)
