I believe the answer is d.
Answer:
In nature the atoms of noble gases do not bond either with other gases or with each other. Helium exists as atoms of Helium not as diatomic molecules. Some of the larger noble gases can be made to form molecules. This does not normally happen in natural conditions.
Explanation:Noble gases are odorless, colorless, nonflammable, and monotonic gases that have low chemical reactivity. The full valence electron shells of these atoms make noble gases extremely stable and unlikely to form chemical bonds because they have little tendency to gain or lose electrons.
To determine strength of attractive forces between the molecules the size of the molecules, their polarity (dipole moment), and their shape. ... If two molecules have about the same size and similar shape, the dipole-dipole intermolecular attractive force increases with increasing polarity.
Answer:
Na2B4O7 + H2SO4 + 5H2O → 4H3BO3 + Na2SO4
Explanation:
The unbalanced equation is given as;
Na2B4O7 + H2SO4(aq) + H2O → H3BO3(s) + Na2SO4(aq)
Balancing the equation of the reaction involves making sure the number of moles of elements in the reactants to be equal to the number of moles of the element of the products.
The balanced equation is given as;
Na2B4O7 + H2SO4 + 5H2O → 4H3BO3 + Na2SO4
Answer:Are these free points
Explanation: because if so I want them
