A is the answer

In an ozone molecule, the three atoms must be connected, so there must at least be a single bond between them. Place

dots in pairs around the oxygen atoms until each oxygen atom has eight valence electrons, starting with the atoms on the

outside and doing the central atom last if there are enough. Do not exceed the total number of valence electrons

identified in part A. Remember that the dashes between the oxygen atoms, which represent single bonds, each indicate

the presence of two valence electrons

moles CO₂ = 5.57.10⁻⁴

<h3>Further explanation </h3>

A mole is a number of particles(atoms, molecules, ions) in a substance

Can be formulated :

$\tt mol=\dfrac{mass}{MW}$

0.7% percent change with 3.5g of plant matter

mass :

$\tt 0.7\%\times 3.5~g=0.0245~g$

moles :

$\tt moles=\dfrac{0.0245}{44}=0.000557=5.57.10^{-4}$

What is the engine piston displacement in liters of an engine who’s displacement is listed as 430 in.²

sergeinik [125]

For an engine whose displacement is listed as 430 in.², the engine piston displacement in liters is mathematically given as

PD= 7.37 L

<h3>What is the engine piston displacement in liters of an engine whose displacement is listed as 430 in.²?</h3>

Generally, the equation for the dimensional analysis method,\, we convert in to L is mathematically given as

l*(v/l)*l/v

Therefore, piston displacement

PD=(450 in3) . (1 dm3 / 61.024 in3) . (1 L / 1 dm3)

PD= 7.37 L

In conclusion, piston displacement

PD= 7.37 L
