construct the lewis structure of no2no2 . draw the molecule by placing atoms on the grid and connecting them with bonds. include all lone pairs of electrons and nonbonding electrons.
Although NO2 is a bent molecule, when you take an electron out of it to get NO2+, the molecule becomes linear as a result of the loss of a lone electron.
What is the number of electrons in the Lewis structure of NO2 ?The Lewis structure of NO2 has 18 valence electrons in total. In the NO2-Lewis structure, nitrogen is the least electronegative atom, hence it is placed in the middle of the structure.
Why do no2's 18 valence electrons exist?In the nitrite ion, we have 5 valence electrons for nitrogen, 6 for oxygen, but since there are 2 oxygen atoms, we will double that number by 2, plus 1 for this valence electron up top, giving us a total of 18 valence electrons for the Lewis structure of the nitrite ion.

2. 2CO(g) ⇌ C(s) + CO2(g)
3. N2O4(g) ⇌ 2NO2(g)
1. CO(g) + H₂O(g) ⇌ CO₂(g) + H₂(g), the number of moles of products remains the same.
2. 2CO(g) ⇌ C(s) + CO₂(g), the number of moles of products increase.
3. N₂O₄(g) ⇌ 2NO₂(g), the number of moles of products decrease.
What is equilibrium?Any change in the equilibrium can be studied on the basis of Le-Chatelier's principle. This principle can describe that for any change in the variables of the reaction, the equilibrium shift in the direction to minimize the effect of that change.
CO(g) + H₂O(g) ⇌ CO₂(g) + H₂(g)
On increasing the pressure, the equilibrium shift in direction where decrease in pressure is occurring, the reaction will shift in no direction because the number of gaseous moles is the same on both sides. Therefore, no increase in the number of moles of products.
2CO(g) ⇌ C(s) + CO₂(g)
On increasing the pressure, the reaction will shift in a forward direction because the number of gaseous moles is less on the product sides. Therefore, increase in the number of moles of products.
N₂O₄(g) ⇌ 2NO₂(g)
On increasing the pressure, the reaction will shift in a backward direction because the number of gaseous moles is less on reactant side both sides. Therefore, decrease in the number of moles of products.

Which of the following atoms tend to form ionic bonds?
Metal and nonmetal ions form ionic connections. For instance, the ionic link between the nonmetal chloride (Cl) and the metal sodium (Na), creating the compound NaCl.
Which metals are prone to creating ionic bonds?Only between nonmetals and metals do ionic bonding develop. Because nonmetals "desire" to gain electrons but metals "want" to give up electrons, this is the case. In order to create a positive ion and remove the valence electrons from an atom, energy is required.
Ionic connections between Na and F exist?As a result, an ionic bond between Na and F is created, with Na losing one valence electron to become Na+ and F gaining one to produce F. Therefore, the NaF bond is ionic.

The chemical equation below shows the photosynthesis reaction.
6CO2 + 6H2O Right arrow. C6H12O6 + 6O2
The molar mass of carbon dioxide (CO2) is 44.01 g/mol. The molar mass of water (H2O) is 18.02 g/mol. A reaction uses 528 g of CO2. How many moles of water are used in this reaction?
12 mol of water are used in this reaction.
Step by Step Explanation:528 g of CO2/ (44.01 g/mol CO2) = 12 moles CO2
12 moles CO2 (6 moles H2O/ 6 moles CO2) = 12 moles H2O
12 moles H2O (18.01 g/mol H2O) = 216.12 grams H2O
What is Photosynthesis?Phototrophs transform light energy into chemical energy through a process called photosynthesis, which is then used to power cellular processes. In the form of sugars, which are made from water and carbon dioxide, the chemical energy is kept in reserve.According to the definition of photosynthesis, the process only occurs in the chloroplasts using photosynthetic pigments like carotene, xanthophyll, chlorophyll a, and b. Photosynthesis is a process used by all green plants and a few other autotrophic organisms to create nutrition from carbon dioxide, water, and sunlight. Oxygen is a byproduct of the photosynthesis process.To learn more about Photosynthesis refer to:
