Answer:

1.553 M^2s^-1

Explanation:

Now let us consider experiments 1,2,3.

In experiment 1 and 2, the concentration of NO is doubled and the initial rate of reaction is quadrupled.

0.575/0.144 = 4

So;

2^2 =4

In experiment 2 and 3

The concentration of reaction of H2 is doubled and the rate of reaction is doubled.

0.575/0.287 = 2

2^1 =2

So we can now write;

Rate =k[NO]^2 [H2]^1

Taking up the first reaction;

0.144 =k [0.475]^2 [0.411]

k = 0.144/ [0.475]^2 [0.411]

k = 1.553 M^2s^-1

How many moles of helium gas are contained in a 4.0 L flask at STP
Ratling [72]
First, you convert liters to moles. 
Usually you have to go to grams but this is STP.

Get moles directly by dividing the 4 by STP (22.4)
\frac{4}{22.4} =0.17857142857
About 1.8*10^{-1} or 0.18 moles whichever your teacher prefers

If a liter of water is cooled from 50 to 30 what happens to its volume
dangina [55]
In general when you heat up a liquid such as water its volume "increases" as the heat energy causes the water molecules to move leading to more space between molecules causing it to occupy a larger volume.

hope that helps

In water, Vanillin, C8H8O3, has a solubility of 0.070 moles of vanillin per liter of solution at 25C. What will be produced if 5
Rufina [12.5K]

Answer:

The full amount (5.00 g) will be dissolved in 1 L of water at 25°C.

Explanation:

The molecular weight (MW) of Vanillin (C₈H₈O₃) is calculated from the chemical formula as follows:

MW(C₈H₈O₃) = (12 g/mol x 8) + (1 g/mol x 8) + (16 g/mol x 3) = 152 g/mol

If 0.070 mol of C₈H₈O₃ are soluble per liter of water at 25°C, the maximum mass that can be dissolved in 1 L is:

0.070 mol x 152 g/mol = 10.64 g

Since 5.00 g is lesser than the maximum amount that can be dissolved (10.64 g), the added amount will be completely dissolved in 1 L of water at 25°C.
