The answer is C They are able to be divided by a chemical reaction.
<u>Answer:</u> The hydrogen ion concentration in apple juice is
<u>Explanation:</u>
pH is defined as negative logarithm of hydrogen ion concentration. It is basically defined as the power of hydrogen ions in a solution.
Mathematically,
We are given:
Putting values in above equation, we get:
Hence, the hydrogen ion concentration in apple juice is
Answer:
D. <span>10 mol of solute/ 1L of solution
Explanation:
Molarity is used to express the concentration of the solution. It is expressed as the number of moles of solute per liter of solution
Molarity = moles of solute / liters of solution
This means that molarity has the units moles/liter
The only option satisfying this is the last one.
Hope this helps :)</span>
Answer: The number of neutrons will increase as we move from left to right in a periodic table.
Explanation:
Atomic number is equal to the number of protons.
Mass number is the sum of number of neutrons and number of protons.
As we move from left to right, both the atomic number and mass number increases.
For example: As we move from Lithium to berrylium to boron to carbon to nitrogen to oxygen to fluorine to neon , the number of neutrons increase from 4 to 5 to 6 to 6 to 7 to 8 to 10 to 10.
Thus the number of neutrons will also increase as we move from left to right in a periodic table.
Answer:
Wavelength = 16.48 µm
Explanation:
As we know...
Wavelength = Speed of light / Frequency
Wavelength = 3 x 10^8 / 18.2 x 10^12
Wavelength = 0.1648 x 10^-4 m = 16.48 µm
