Sulfur trioxide (triangular planar) formed by double covalent bonds, is a compound that presents polar bonds although the dipole moments associated with each bond are canceled by symmetry, resulting in apolar molecules.
What is SO3?It is a nonpolar molecule that contains one sulfur atom bonded to three oxygen atoms.
Characteristics of the types of bonding present in the molecule SO3It is a molecule formed by covalent double bonds between S and O atoms, whose molecular formula is SO3.In SO3 there are three bonds between S and O, the first bond is formed by sharing two pairs of electrons (double bond), with this double bond the S and O complete the octet.S has two other pairs of electrons in the valence shell and gives each pair to two O atoms, thus completing its octet, forming two other bonds called dative covalent bonds.Therefore, we can conclude that SO3 is a nonpolar molecule due to its geometry (trigonal planar) and the absence of a lone pair of electrons.

The partial pressure of the mixture is equal to the sum of the individual pressure.The partial pressure of the remaining gas measured will be 0.8 atm.
What is partial pressure?The partial pressure of the mixture is equal to the sum of the individual pressure of the gases present in ther mixture.
The given date in the problemis
Total pressure of the mixture=P
P₁ is the partial pressure of gas 1 (N₂) =1.2 atm
P₂ is the partial pressure of gas 2(F₂)= 2.0 atm
P₃ is the partial pressure of the gas 3(H₂)=1.0 atm
P₄ Is the partial pressure of the gas 4=?
From the defination
P=P₁ +P₂ +P₃+P₄
5=1.2+2.0+1.0+P₄
P₄=0.8 atm
Hence the partial pressure of the remaining gas that was not measured will be 0.8 atm.

What volume will 2. 0 moles of nitrogen occupy at 720 torr and 20. 0°C? Formula: PV = nRT (R = 62. 396 L•torr/mol•K) 3. 5 L 6. 6 L 48 L 51 L.
Answer:
the answer is 51 L please brainliest
Explanation:
The volume of 2. 0 moles of nitrogen at 720 torr and 20. 0°C is 51 L
Finding volume of Nitrogen
Using the formulae, PV=nRT
Recall that
1 torr= 0.00132atm
Such that
P=720torr =720 x 0.00132atm= 0.95atm
Also,
V= 20°C= 20+273= 293K
R=0.08206L-atm/mol-K
Solving, we have that
PV=nRT
0.95×V= 2×0.08206×293
V= 2×0.08206×293/ 0.95
V= 50.62L
Rounded to 51 L.

S + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O
In the above equation how many moles of water can be made when 134 grams of HNO3 are consumed?
Round your answer to the nearest tenth. If you answer is a whole number like 4, report the answer as 4.0
Answer:
S + HNO3 = H2SO4 + NO2 + H2O
Explanation:
Answer:
Based on stoichiometry HNO3 to H2O is 6:2
Use 9 grams to find the moles of HNO3
9 grams/63g/mol=0.143 moles of HNO3
HNO3:H2O
6:2
0.143*2/6=0.048
H2O moles is 0.048moles

Which phrase defines bond energy? (1 point)
energy output when product bonds form
energy required to break a chemical bond
energy stored in chemical bonds

The phrase that defines bond energy is the energy required to break a chemical bond.
WHAT IS BOND ENERGY?Bond energy is amount of energy needed to break the atoms involved in a chemical bond into free atoms.
The bond energy of each molecule varies with the type of bond in the molecule. Stronger bonds require a higher bond energy and vice versa.
Therefore, the phrase that defines bond energy is the energy required to break a chemical bond.

Answer:
D. Energy input needed to break bonds of reactants.
Explanation:
Activation energy is the minimum amount of energy required to initiate a chemical reaction by breaking the bonds of the reactants. It is the energy needed to reach the transition state, where the reaction can proceed, and new chemical bonds can be formed to create the products. The activation energy is the energy barrier that must be overcome for a reaction to occur.
Once the reactants have enough energy to overcome the activation energy, the reaction proceeds spontaneously, and energy is released when new bonds form in the products.

Answer:
"Soaps are made from natural ingredients, such as plant oils (coconut, vegetable, palm, pine) or acids derived from animal fat. Detergents, on the other hand, are synthetic, man-made derivatives. While soap is limited in its applications, detergents can be formulated to include other ingredients for all sorts of cleaning purposes. Perhaps the most common and versatile of these ingredients are surfactants … surface active agents.

metal atoms lose electrons from their outer shell to form positively charged ions
From groups 1 to 3 the charge is the same as the group number
Non metals gain electrons on their outer shell to form negatively charged ions
From groups 5 to 7 the charge is 8 subtract the group number

So here , we can make a table as ,
[tex]\begin{array}{c|c} \\ LHS & RHS \\\\ Zn = 1 & Zn = 1 \\\\ SO_4 = 1 & SO_4 =1\\\\ Li = 2 & Li= 2 \\\\ CO_3 = 1 & CO_3 = 1 \end{array}[/tex]
We can see that the number of elements and ions is same on both LHS and RHS . Hence the reaction is already balanced .
Therefore the final reaction would be same as before that is ,
