You need to take into account the equations for the average speed and kinetic energy of gases.

Kinetic energy, KE = [1/2] m * v^2

Average speed, v = √[3RT/m] => v^2 = 3RT / m

=> KE = [1/2]m * 3RT/m = [3/2] RT

R = 8,314 J/mol*K

T = 254 K

=> KE = [3/2]*(8,314J/mol*K)*(254K) = 3167.6 J/mol

Answer: 3167.6 J/mol

Spell out the full name of the compound.
Natalka [10]

Explanation:

Step one look for the longest chain of carbon atoms

Longest chain is 7 C atoms

Step 2 look for double bonds or others functional groups

it is present in 3rd carbon

Therefore IUPAC name is 3-heptene

From point of stereochemistry it can also be written as trans-3-heptene as the hydrogens are placed in opposite side of the C=C bond.

Hope this helps...

How many kilograms of water must be added to 6.07 grams of oxalic acid (H2C2O4) to make a 0.025 m solution?
uranmaximum [27]
This dilution problem uses the equation

a
=
M

V

M
a
= 6.77M - the initial molarity (concentration)
V
a
= 15.00 mL - the initial volume
M
b
= 1.50 M - the desired molarity (concentration)
V
b
= (15.00 + x mL) - the volume of the desired solution
(6.77 M) (15.00 mL) = (1.50 M)(15.00 mL + x )
101.55 M mL= 22.5 M mL + 1.50x M
101.55 M mL - 22.5 M mL = 1.50x M
79.05 M mL = 1.50 M
79.05 M mL / 1.50 M = x
52.7 mL = x
59.7 mL needs to be added to the original 15.00 mL solution in order to dilute it from 6.77 M to 1.50 M.
I hope this was helpful.

2. Explain Why would it be difficult to find the volume of a rock using<br> a ruler?
dedylja [7]

Answer:

Most of these rocks are not made up of common geometric shapes

Explanation:

Because most rocks are not made up of common geometric shapes, it would be difficult or impossible to find the volume of a rock using a ruler; there would be no easy way to measure the rock's volume using a ruler

Hope this helped!
