NF3 Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons. +- CHONS
hram777 [196]

Here is the correct question.

Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.

NF3

SBr2

CCl4

Answer:

Explanation:

The objective here is to draw the molecule three molecules by placing atoms on the grids and connecting them with their respective bonds, therefore including all the lone pairs of electrons.

See the attachment below for the diagrams.

The first compound is know as Nitrogentrifluoride. A non-flammable greenhouse gas. It is majorly used for he production of semi conductors. It has a trigonal planar structure.

SBr2: Sulfur dibromide is a yellowish liquid toxic gas. It results as a reaction between SCl_2 and HBr. Its has a Bent Structure.

CCl_4 : carbon tetrachloride has the presence of a colourless liquid with a sweet smell. Carbon tetrachloride is used for different domestic uses such as: cleaning surfaces, fumigating, cleaning metals etc. It has a tetrahedral structure.

What is the relationship between the number of particles in a substance, the number of moles, and the mass of the substance
Vedmedyk [2.9K]

Answer:

One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro's number or Avogadro's constant. The concept of the mole can be used to convert between mass and number of particles

What is the balanced form fir Na(s) + ao2(g) = Na2O(s)​
Dima020 [189]

Answer:

Balanced Chemical equation:

4Na + O₂ → 2Na₂O

Explanation:

Chemical equation:

Na + O₂ → Na₂O

Balanced Chemical equation:

4Na + O₂ → 2Na₂O

Four mole of sodium combine with one mole of oxygen and form two mole of sodium oxide.

Coefficient with reactant and products:

Na   4

O₂     1

Na₂O  2

Oxygen is present in group sixteen and have six valance electrons. while sodium is alkali metal and present in group one and have one valance electron.

Oxygen needs two electron to complete the octet while sodium need to lose the one electron to get the complete octet.

When oxygen is combine with sodium it gain its two valance electrons from two sodium atom and form anion while sodium loses its valance electron to wards oxygen and form cation. The bond form between them is ionic because one is metal and other is non metal and electrons are completely transfer from two sodium atom to one oxygen atom.

How many grams of C are in 500g or NaHCO3​
harina [27]

Answer: 71.43g

Explanation: The RMM of NaHCO3 is

23+1+12+16(3)=84.

There is one carbon in NaHCO3 thus there are 1×12g of C in NaHCO3.

Thus

85gNaHCO3-----12g C

500gNaHCO3---- xgram

(500×12)÷84= 71.43
