What is the rate of a reaction if the value of k is 3 and A and B are each 2 M Rate kA2B?
4vir4ik [10]

Answer:

Rate= 24

Explanation:

Rate = k[A]^2[B]

k= 3, [A]=2M, [B]=2M

Rate= 3×(2)^2×2= 24

Substitute into above

Give the characteristic of a first order reaction having only one reactant.
Slav-nsk [51]

Answer:

As the first order reaction depends on (a uni-molecular reaction) the concentration of only one reactant.

And the rate law of the reaction of first order with a reactant A is:

rate = K[A]^-1

when K is the rate constant.

Calculate to three significant digits the density of dinitrogen monoxide gas at exactly and exactly . You can assume dinitrogen
Ulleksa [173]

Answer:

see explanation below

Explanation:

You miss the part of the temperature and pressure. According to what I found this is held under 30 °C (or 303 K) and 1 atm.

The problem states that we can treat this gas as an ideal gas, therefore, we can use the equation of an ideal gas which is:

PV = nRT (1)

Now, the density (d) is calculated as:

d = m/V (2)

We can rewrite (2) in function of mass of volume so:

m = d*V (3)

Now, the moles (n) of (1) can be calculated like this:

n = m /MM (4)

If we replace it in (1) and then, (3) into this we have the following:

PV = mRT/MM ----> replacing (3):

PV = dVRT/MM ----> V cancels out so finallly:

P = dRT/MM

d = P * MM / RT (5)

The molar mass of N2O is 44 g/mol So, replacing all the data we have:

d = 1 * 44 / 0.082 * 303

d = 1.77 g/L

Suppose Earth was tilted much less on its axis. What effect would this have on the planet? Please help me !
hodyreva [135]

Answer:

If Earth was tilted much less on its axis, it would lead to minor changes in precipitation and temperatures as Earth moves slightly towards and away from the sun.

Explanation:

If a planet tilts more, it leads to colder winters and warmer summers. However, if a planet tilts less, it leads to less severe seasons that is and milder winters and cooler summers.

If Earth was tilted much less on its axis, it would lead to minor changes in precipitation and temperatures as Earth moves slightly towards and away from the sun.
