Answer:
a. nitrate ion
e. sulfur dioxide
Explanation:
Trigonal planar geometry, is possible, where the combination of atoms or lone pain form a triangle which is is same plane.
Hence, from the given options,
- Nitrate ion has a trigonal planar geometry.
- Carbon tetrachloride has a teterahedral geometry
- water has a bent angular geometry.
- sulfur dioxide has a trigonal planar geometry.
Therefore,
From the given options, the correct answer is -
a. nitrate ion
e. sulfur dioxide
Answer:
1 unshared pair of electrons
Explanation:
In order to draw the Lewis structure, we need to consider the octet rule: atoms tend to share electrons to complete their valence shell with 8 electrons. In the case of H, it has to complete a duet (2 valence electrons).
N has 5 valence electrons, so it has to share 3 pairs of electrons to reach the octet.
H has 1 valence electron, so it has to share 1 pair of electrons to reach the duet.
In the picture, we can see the resulting Lewis structure. There is 1 unshared pair of electrons on each nitrogen.
The complete question would be as follows:
700,000 tons of baking soda are produced per year. <span>How many kilograms of carbon dioxide are used per year to produce baking soda?
We calculate as follows:
</span><span>CO2(g) + NH3(aq) + NaCl(aq) + H2O -----> NaHCO3(s) + NH4Cl(aq)
</span>
700000 tons NaHCO3 ( 907.185 kg / 1 ton ) (<span>1 kmole NaHCO3 / 84.0 kg NaHCO3) x (1 kmole CO2 / 1 kmole NaHCO3) x (44.0 kg CO2 / 1 kmole) = 3x10^8 kg CO2
Hope this answers the question. Have a nice day.</span>
