Answer and Explanation:
Carbon dioxide (CO₂) dissolves in water and gives carbonic acid (H₂CO₃) which then dissociates first in HCO₃⁻ and then in CO₃⁻. So, its ionization increases the concentration of H⁺ and the solution becomes more acidic. If you measure the pH of a sample by using a colorimetric indicator and then you exhale your CO₂ in the sample, you will see that the indicator changes its color to the correspondent to a acid solution.
Answer:
Formation. Main-sequence stars, including the sun, form from clouds of dust and gas drawn together by gravity. ... The core that is left behind will be a white dwarf, a husk of a star in which no hydrogen fusion occurs. Smaller stars, such as red dwarfs, don't make it to the red giant state.
Explanation:
233.1g
Explanation:
Given:
Formula units of FeCl₃ = 8.65 x 10²³ formula units
Unknown:
Mass of the FeCl₃ = ?
Solution:
The formula unit is the same as the amount of subatomic particles in an atom.
1 mole of a substance = 6.02 x 10²³ formula units
For 8.65 x 10²³ formula units; the number of moles;
Number of moles = = 1.44moles
Now to find the mass of FeCl₃;
Mass of FeCl₃ = 1.44 x 162.2 = 233.1g
