The given figure is Lewis structure of BrF₃ and its polarity.
A Lewis structure is based on the concept of the octet rule, in which atoms share electrons so that each atom has eight electrons in its outer shell.
Lewis structures, also known as Lewis-dot diagrams, show the bonding relationship between atoms of a molecule and the lone pairs of electrons in the molecule. Lewis structures can also be useful in predicting molecular geometry in conjuntion with hybrid orbitals.
Net dipole moment of this molecule is not zero. Hence, this is polar molecule.

Answer:
The correct option is 9
Explanation:
The easiest way to balance any combustion equation is to first write the general form. In a combustion reaction the products are always carbon dioxide (CO2) and water (H2O) and the reactants are the organic material plus oxygen (O2).
General Form:
C6H12 + O2 --> CO2 + H2O
Now start by balancing the carbon atoms:
six carbons on the left so you need 6 on the right.
C6H12 + O2 ---> 6 CO2 + H2O
Next balance the hydrogen atoms:
12 on the left, so you need 12 on the right.
C6H12 + O2 --> 6CO2 + 6H2O
Now count the number of oxygen on the right = 12 + 6= 18
Divide the number on the right by 2 to get the number needed on the left. 18/2 = 9
It would be that Electrical energy is converted to chemical energy only when there is an external power source because there are both kinds of cells that are electrochemical to which an arode is an electrode to which there is half-reaction on the oxidation and another half-reaction on the reduction but only for the electrode cathode. The main cell that converts chemical energy into electrical energy is a called the Galvanic energy.
9,000 meters
Because density is altered by altitude, the helium balloon can reach a height of 9,000 meters, or 29,537 feet. Anything higher than this altitude will cause the helium within the balloon to expand and the balloon to pop.
Answer is: <span>requirement of valine is 0,0222 mol for a100 kilograms adult.
</span>m(C₅H₁₁NO₂) = 2,60 g.
M(C₅H₁₁NO₂) = 5 · 12 + 11 · 1 + 1 · 14 + 2 · 16 · g/mol.
M(C₅H₁₁NO₂) = 117 g/mol.
n(C₅H₁₁NO₂) = m(C₅H₁₁NO₂) ÷ M(C₅H₁₁NO₂).
n(C₅H₁₁NO₂) = 2,60 g ÷ 117 g/mol.
n(C₅H₁₁NO₂) = 0,0222 mol.
n - amount of substance.
m - mass of substance.
M - molar mass of substance.
