What is the rate for the second order reaction Products when [A] = 0.371 M? (k = 0.761 M's")​
AlekseyPX

Given :

Concentration of product [A] = 0.371 M .

Rate constant , R = 0.761\  M^{-1}t^{-1} .

To Find :

The rate for the reaction .

Solution :

We know , for second order reaction , rate is given by :

r=k[A]^2\\\\r=0.761\times 0.371^2\ M/t\\\\r=0.10\ M/t

Therefore , the rate for the second order reaction is 0.1 M/t .

Hence , this is the required solution .

How does the altitude of the Sun change throughout the year in Reno, NV?
vampirchik [111]

Given what we know, we can confirm that in Reno, NV, the angle of the Sun is lower during the winter months and <u>higher </u>in the <u>sky </u>during the summer.

<h3>How can we know this?</h3>

We can know this about Reno, NV, given that it is irrelevant where we placed this question. the answer will be the same all across the world. It has to do with the way the Earth orbits the Sun as well as the tilt of the Earth. This causes the Sun to be higher in the sky during summer and lower in the winter months.

Therefore, we can confirm that the angle of the Sun is lower during the winter months and higher in the sky during the summer, both in Reno, NV and everywhere else.

C3H8 + 5 O2 → 3 CO2 + 4 H2O
Reika [66]

Answer:

Mass = 112 g

Explanation:

Given data:

Mass of CO₂ produced = 90.6 g

Mass of oxygen needed = ?

Solution:

Chemical equation:

C₃H₈ + 5O₂       →      3CO₂+ 4H₂O

Number of moles of CO₂:

Number of moles = 90.6 g/ 44 g/mol

Number of moles = 2.1 mol

Now we will compare the moles of  CO₂ and oxygen:

                 CO₂           :           O₂

                    3             :            5

                    2.1           :        5/3×2.1 = 3.5

Mass of oxygen needed:

Mass = number of moles × molar mass

Mass = 3.5 mol × 32 g/mol

Mass = 112 g
