The "Ideal Gas Law Equations" is 
PV=nRT
P= Pressure (in Pascals)
V=Volume (in Liters)
n=amount, or <u>n</u>umber (in moles)
R= 8.3145 \frac{Pascals*Liters}{Moles*Kelvin} or \frac{PaL}{molK}
T= Temperature (In Kelvin)

P= \frac{nRT}{V}

Plug into the equation and you're good!
P=\frac{nRT}{V}
P =\frac{(5mol)(8.3145)(286K)}{2L}
P=5944.8675Pa

If your teacher cares about sig figs,
2 sig figs (significant figures)
P=5900Pa

For other units of pressure,
1 atm = 760 mmHG = 760 Torr = 101326 Pa = 1.01325 bar<u />

For which structure(s) does the electron-bearing carbon atom have a formal charge of zero
AlladinOne [14]

Formal charge can be calculated from the following formula

Formal charge = valency of central atom - (number of lone pair of electrons + number of covalent bonds)

a) for methylene:

Formal charge = 4 -( 2+ 2) = 0

b) For methyl free radical

Formal charge = 4- (3 +1) = 0

A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is
Airida [17]

Answer:

the maximum safe operating temperature the engineer should recommend for this reaction is 616 °C  

Explanation:

Given the data in the question;

First we calculate the Volume of the steel cylinder;

V = πr²h

radius r = Diameter / 2 = 27 cm / 2 = 13.5 cm

height h = 32.4 cm

so we substitute

V = π × ( 13.5 cm )² × 32.4 cm

V  = π × 182.25 cm × 32.4 cm

V = 18550.79 cm³  

V = 18.551 L

given that; maximum safe pressure P = 3.10 MPa = 30.5946 atm

vessel contains 0.218kg or 218 gram of carbon monoxide gas

molar mass of carbon monoxide gas is 28.010 g/mol

so

moles of carbon monoxide gas n = 218 gram /  28.010 g/mol = 7.7829 mol

we know that;

PV = nRT

solve for T

T = PV / nR

we know that gas constant R = 0.0820574 L•atm•mol⁻¹ K⁻¹

so we substitute

T = ( 30.5946 × 18.551 ) / ( 7.7829 × 0.082 )

T = 567.5604 / 0.6381978

T = 889.317387 K

T = ( 889.317387 - 273.15 ) °C

T = 616.167 ≈ 616 °C  { 3 significant digits }

Therefore, the maximum safe operating temperature the engineer should recommend for this reaction is 616 °C

Determine the hybrid orbital of this molecule.
Pavel [41]

The hybrid orbital of this molecule is sp^3. Hence, option C is correct.

<h3>What is hybridisation?</h3>

Hybridization is defined as the concept of mixing two atomic orbitals to give rise to a new type of hybridized orbitals.

In this compound, sp^3 a hybrid orbital makes I-O bonds. Due to sp^3hybridization iodate should have tetrahedral geometry but because of the presence of lone pair of electrons the shape of IO^{3-} the ion is pyramidal.

The hybrid orbital of this molecule is sp^3. Hence, option C is correct.
