Why do certain substances dissolve in water and others don't? *
ipn [44]
<h2>Answer: <u><em>Hope this helps</em></u></h2>

Explanation:

<h3><u><em>Why do some substances dissolve in water and others don't? It has to do with the structure of the water molecule. Oxygen has a greater attraction for electrons, so the shared electrons (bonding electrons) spend more time close to oxygen then to either of the hydrogens.</em></u></h3>

A particular isotope of uranium has a nucleus with 92 protons and 143 neutrons identify this isotope in two diffrent ways
inn [45]

Isotopes can represented in two ways. In the first way, the element's symbol is used with mass number at the upper left and atomic number written on the lower left of the symbol. In the other form of representation, the isotope name is written with a dash and mass number.

Given that the isotope has 92 protons. So the atomic number is 92.

The isotope has 143 neutrons

So the mass number = Total number of protons + Neutrons

                                  = 92 + 143 = 235

Therefore, the two ways of representing the isotope is:

1. ^{235}_{92} U

2. Uranium-235

slavikrds [6]

True

Explanation:

when a physical change occurs in a substance, the appearance might change but the chemical identity remains same. For example, if liquid water is heated, the water changes to gaseous form .This means the appearance of the water has changed, but the chemical identity remains same as both liquid water and steam has both oxygen and hydrogen as the component molecules or atoms.
