Both Nitrates and Nitrites are inorganic chemical compounds, and as the names imply, the characteristic element in them is ‘N’ or Nitrogen, which has an atomic number of 7.

Hope this helps.

Both Nitrates and Nitrites are inorganic chemical compounds, and as the names imply, the characteristic element in them is ‘N’ or Nitrogen, which has an atomic number of 7. Nitrogen is an odourless diatomic gas in nature and is reactive. The element Nitrogen is also highly electro-negative. And both Nitrates and Nitrites are two important classes of Nitrogen-containing compounds. The main difference between Nitrate and Nitrite is that Nitrate group contains one Nitrogen atom and three Oxygen atoms whereas Nitrite group contains one Nitrogen atom and two Oxyg

Neon gas has a volume of 261 ml and a pressure of 108.5 kPa. What volume will the gas occupy at 96.5 kPa if the temperature rema

Tatiana [17]

Answer:

$\large \boxed{\text{293 mL}}$

Explanation:

The temperature and amount of gas are constant, so we can use Boyle’s Law.

$p_{1}V_{1} = p_{2}V_{2}$

Data:

$\begin{array}{rcrrcl}p_{1}& =& \text{108.5 kPa}\qquad & V_{1} &= & \text{261 mL} \\p_{2}& =& \text{96.5 kPa}\qquad & V_{2} &= & ?\\\end{array}$

Calculations:

$\begin{array}{rcl}108.5 \times 261 & =& 96.5V_{2}\\28320 & = & 96.5V_{2}\\V_{2} & = &\dfrac{28320}{96.5}\\\\& = &\textbf{293 mL}\\\end{array}\\\text{The volume of the gas is } \large \boxed{\textbf{293 mL}}$

This kind of bond is formed when an atom with low electronegativity donates electrons to an

Butoxors [25]

Answer:

Ionic Bond

Explanation:

The atom with the higher electronegativity wants to fill its valence electron shell (meaning it wants 8 electrons in this shell). The atom with lower electronegativity will want to empty or donate an electron so that it can have an empty valence shell.

Which of the following species cannot act as a Lewis base?

gayaneshka [121]

Answer:

NH4+

Explanation:

A Lewis base is a substance with the ability to share or give pairs of electrons.

The NH4 + ammonium ion donates a proton, therefore the ammonium ion is a Lewis acid.
