Atoms which might substitute for one another can be found in the same column in the periodic table. 
So, since Si and C are found in the same column, they can substitute each other.
1. Si = C
2. K = Na
3. Nb = V
4. Cu = Ag
5. P = As
6. Mg = Ca

Phenol red is an indicator that changes color over a range from ph=6.4 to ph=8.0. what is ka of phenol red?
patriot [66]
First, we will get the average pH of the two given values:
average pH = (6.4+8) / (2) = 7.2
At this average pH, the concentration of the acid from the phenol red is equal to the concentration of the base.
pH = 7.2
[H+] = 10^(-7.2) = 6.3 * 10^-8

Phenol red has the general formula HA, this gives us:
HA <.......> H+ + A- 
At pH = 7.2, [H+] = [A-]
<span>Ka = [H+][A-]/ [HA]
</span>Ka = [H+] = <span>6.3 x 10^-8</span>

You heat 3.869 g of a mixture of fe3o4 and feo to form 4.141 g fe2o3. What is the mass of oxygen reacted?
Lostsunrise [7]

The reaction is  

FeO + Fe3O4 + 1/2 O2---> 2Fe2O3

Thus as shown in the balanced equation two moles of Fe2O3 are formed when 0.5 moles of O2 reacted with mixture of FeO and Fe3O4

moles of Fe2O3 = MAss / Molar mass = 4.141 / 159.69 = 0.0259 moles

So moles of O2 needed = 0.5 X 0.0259 = 0.01295

Mass of O2 = moles X molar mass = 0.01295 X 32 = 0.4144 grams

An atom has 24 protons and 23 electrons and 28 neutrons what charge does this atom have?
alina1380 [7]

Answer:

1+

Explanation:

the number of protons tells you which element it is in the periodic table, you can notice that there is 1 less electron that then there is protons which means that the element had to give 1 electron away. When you get rid of 1 e- you have 1 proton more that electrons so that's why it's 1+

also the element is Cr
