Answer:Concrete is a heterogeneous mixture of an aggregate: cement, and water.
Sugar and sand form a heterogeneous mixture. If you look closely, you can identify tiny sugar crystals and particles of sand.
Ice cubes in cola form a heterogeneous mixture. The ice and soda are in two distinct phases of matter (solid and liquid).
Salt and pepper form a heterogeneous mixture.
Chocolate chip cookies are a heterogeneous mixture. If you take a bite from a cookie, you may not get the same number of chips as you get in another bite.
*Soda is considered a heterogeneous mixture. It contains water, sugar, and carbon dioxide, which forms bubbles. While the sugar, water, and flavorings may form a chemical solution, the carbon dioxide bubbles are not uniformly distributed throughout the liquid.
An example of homogenization is homogenized milk, which is processed so that the milk components are stable and don't separate.
In contrast, natural milk, while it might appear homogeneous when shaken, isn't stable and readily separates into different layers.
I hope that helped!
ANSWER
They are positively charged and move toward an anode
Option C
EXPLANATION
In electrochemical reaction, cation are positively charged. Since they are positively charged, they move toward negatively charged anode
There are two types of reaction which are oxidation and reduction reaction. At oxidation, the positively charged cations move towards the negatively charged anode.
Recall, that like charges attract and unlike charges repel.
Therefore, the correct answer is option C
Answer: An initial velocity
Explanation:
Explanation:
To solve this question, we will use the Clayperon Equation:
P.V = n.R.T
where:
P = 101.28 kPa
1 atm = 101,325 Pa
x atm = 101,280 Pa
x = 1 atm
V = 37.058 L
n = we don't know
R = 0.082 atm.L/K.mol
T = -139.88 ºC = -139.88+273.15 = 133.27 K
1*37.058 = n*0.082*133.27
n = 0.29 moles
Answer: 0.29 moles
It is really easy if you look up an electron configuration table (one that looks like a periodic table) and then just go down the rows left to right, top to bottom, and just stop when you get to where the element is on the table.
