The element found naturally in the earth , that has the highest atomic number is 7
Answer:
Explanation:
The pH of a solution can be found by using the formula
![pH = - log [ {H}^{+} ]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B%20%7BH%7D%5E%7B%2B%7D%20%5D)
Since we are finding the H+ ions we find the antilog of the pH
So we have
We have the final answer as
Hope this helps you
Answer:
Great question!The color of grass leaves (usually green) is mostly due to the absorbance of the other wavelengths of visible light by chlorophyll. Therefore, any differences in gene expression (that ultimately determine phenotype) that affect the concentration of chlorophyll in the leaf will, in turn, affect the color of that leaf. My guess is that, in the absence of light, you could still measure chlorophyll concentration, and assume what the color would be. However, you need transmitted (reflected) light in order to perceive color. I don't know, if a tree falls in the forest, and none is around to hear it, does it make a sound? Hope this helps. Keep the questions coming!

C is the answer because that is an actual chemical change where the sulfur and iron are not separate from each other anymore
The moles of barium nitrate in the solution has been 0.5 mol. Thus, the correct option is B.
Molarity has been defined as the moles of substance in a liter of solution. Molarity has been expressed as:
<h3>Computation for moles of Barium nitrate</h3>
The given barium nitrate solution has the volume of 0.25 L.
The molarity of the solution has been 2 M.
Substituting the values for the moles of Barium nitrate
The moles of barium nitrate in the solution has been 0.5 mol. Thus, the correct option is B.
