Nickle (II) sulfite - b/c the charge on Ni can be +2 or +3 i Believe. SO3 has a charge of -2 the you need nickel II (+2) to make a proper ionic bond
It’s A .. I think I hope this helps !
Active metals are those metals in the group 1 of the periodic table.
Electronegativity is the trend to atract electrons.
Active metals have few valence electron, because their last shell is of the kind ns^1 or ns^2
Then, these atoms do not trend to attract electrons. The most electronegative atomos are those who have 7 valence elecfrons; this is their last shell is of the kind ns^7, because when they attract one electron to its valence shell they will complete 8 electrons which is the most stable configuration.
Nah its only fun if u got friends which i dont
Answer:
2.5 moles of H2
Explanation:
First, let us write a balanced equation for the reaction of Hydrogen to produce water. This is shown below:
2H2 + O2 —> 2H2O
From the equation above,
2 moles of H2 produced 2 moles of H2O.
Therefore, 2.5 moles of H2 will produce 2.5 moles of H2O
