The reaction is actually endothermic because delta H is positive, indicating that it absorbing heat.
Answer:
the answer is C) sharing
Explanation:
positive ions & negative ions form when atom s lose or gain electrons. Covalent bonds form when atoms share electrons.Metallic bonds form by the attraction of metal ions and the electrons around them. Covalent compounds form when atoms of elements share electrons.
Answer:
The answer is
<h2>0.89 atm </h2>
Explanation:
To convert from kPa to atm we use the conversion
101.325 kPa = 1 atm
If
101.325 kPa = 1 atm
Then
90.23 kPa will be
We have the final answer as
<h3>0.89 atm</h3>
Hope this helps you
Thomson's model of the atom was called the plum pudding model. He discovered electrons, so he placed them in the atoms. This was before the nucleus was discovered.
Now, the current model is an atom that contains a positively charged nucleus (with both protons and neutrons), and negatively charged orbitals with electrons.
