What is the main difference between a homogeneous mixture and a heterogeneous mixture?
Sholpan [36]
The answer is <span>The components of a homogeneous mixture are evenly distributed.

In a homogeneous mixture, all components are evenly distributed. They are known as solutions. In a heterogeneous mixture, components are not evenly distributed. It consists of visibly different components. For example, milk is the homogeneous mixture, you cannot see its particles. But milk and cereals are the heterogeneous mixtures.</span>

How many moles of water are produced when 3.45 moles of KMnO4 react? Give your answer to the nearest 0.1 moles. moles H2O
andrew11 [14]

Answer:

13.8 moles of water produced.

Explanation:

Given data:

Moles of KMnO₄ = 3.45 mol

Moles of water = ?

Solution:

Chemical equation:

16HCl + 2KMnO₄ → 2KCl + 2MnCl₂ + 5Cl₂ + 8H₂O

Moler ratio of water and KMnO₄:

             KMnO₄       :        H₂O

                2             :          8

               3.45         :         8/2×3.45 = 13.8 mol

Hence, 3.45 moles of KMnO₄ will produced 13.8 mol of water.

Red lights on a traffic light have a frequency of 4.3 X 10^15 Hz. What is the red light’s wavelength in meters? (Speed of light
Juliette [100K]

Answer:

The correct answer to this problem is B. 7.0 X 10^-8 meters

Explanation:

To solve this problem, we have to use the following equation:

c = λν, or speed of light = wavelength*frequency

If we substitute in the values we are given by the problem, we get:

3.00 * 10^8 m/s = (4.3 * 10^15 Hz)*(wavelength)

wavelength = 6.98 * 10^-8 m

Since the given value has 2 significant figures, our answer should similarly include two significant figures since the operation in the problem was multiplication.

Therefore, the answer is B. 7.0 X 10^-8 meters.

Hope this helps!
