<span>The difference between heterogeneous and homogeneous mixtures is the degree at which the materials are mixed together and the uniformity of their composition. Ahomogeneous mixture is a mixture where the components that make up the mixtureare uniformly distributed throughout the mixture.</span>
Answer:
pH= 1.70
Explanation:
I 4.988 0 0
C -x +x +x
E 4.988 -x x x
8.0 x 10^-5 = X^2/ 4.988 - x
(since the X value is so small, round 4.988-x to 4.988 because X is close to zero)
8.0 x 10^-5 = x^2/4.988
x4.988 x4.988
4.0 x 10^-4 = x^2
x = .0199
pH=-log[.0199] = 1.70
Answer:
<h2>The answer is 0.5 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 5 cm³
density = 0.1 g/cm³
The mass is
mass = 0.1 × 5
We have the final answer as
<h3>0.5 g</h3>
Hope this helps you
The answer is. :
nitrogen has 1s2 2s2 2p3 electronic configuration... it still needs 3e' to get octet structure and become stable.. hence valency=3.
