Compare an oxygen particle to a water particle. In your answer , include describing how they are different and similar.
Naddik [55]

Answer:

An oxygen molecule consists of two oxygen (o2) atoms bound together and a water molecule consists of two hydrogen atoms and one oxygen atom (h20). H20 has a higher evaporation temperature than oxygen therefore it stays a liquid at room temperature unlike oxygen. Both have oxygen atoms.

A box contains 104 gas molecules, 2500 of nitrogen and 7500 of argon in thermal equilibrium. The molecular weight of N2 is 28g/m
LekaFEV [45]

Answer : The temperature of this gas will be, 206.9 K

Explanation :

The expression for the kinetic energy per molecule of monoatomic gas (argon) is:

K.E_{argon}=n_{argon}\times \frac{3}{2}\times K_BT      ...........(1)

The expression for the kinetic energy per molecule of diatomic gas (nitrogen gas) is:

K.E_{nitrogen}=n_{nitrogen}\times \frac{5}{2}\times K_BT      .............(2)

The total kinetic energy of the molecule will be,

K.E_{Total}=K.E_{argon}+K.E_{nitrogen}

Now put all the expression in this, we get:

K.E_{Total}=(7500)\times \frac{3}{2}\times K_BT+(2500)\times \frac{5}{2}\times K_BT

T=\frac{K.E}{17500\times K_B}

Now put all the given values in this expression, we get:

T=\frac{5\times 10^{-17}J}{17500\times (1.381\times 10^{-23}J/K)}

T=206.9K

Therefore, the temperature of this gas will be, 206.9 K

Which of the following compounds is not likely to have ionic bonds LiF, NaCI, CH4, MgF2
Rina8888 [55]

Methane CH_{4} does not have ionic bonds. Because of the close value of electronegativity of the carbon and hydrogen atoms the electrons are shared forming covalent bonds.

What is the volume, in liters, of 576 grams of so2 gas at stp?
katen-ka-za [31]
The volume  in  liters  of  576 grams  of SO2  gas  at STP  is   calculated as below

calculate the moles of SO2 = mass/molar  mass

= 576 g/64 g /mol  = 9 moles

At  STP  1mole =22.4 L
what  9 mole =? liters

by cross  multiplication

= 22.4 L x  9 moles/ 1moles = 201.6 liters
