Answer:
Sun at the center.
Explanation:
The actual dictionary definition of Heliocentric defines it as, "Heliocentrism is the astronomical model in which the Earth and planets revolve around the Sun at the center of the Solar System. Historically, heliocentrism was opposed to geocentrism, which placed the Earth at the center."
Hey there!
Ca + O₂ → CaO
Balance O.
2 on the left, 1 on the right. Add a coefficient of 2 in front of CaO.
Ca + O₂ → 2CaO
Balance Ca.
1 on the left, 2 on the right. Add a coefficient of 2 in front of Ca.
2Ca + O₂ → 2CaO
Our final balanced equation: 2Ca + O₂ → 2CaO
Hope this helps!
Dilution is the process of “lowering the concentration of a solute in a solution by simply adding more solvent to the solution, such as water.” Diluting a solution entails adding more solvent without adding more solute.
<h3>How do you do dilution in math?</h3>
The number of dilutions is equal to the number of times the dilution factor will be multiplied by itself to equal the starting concentration divided by the final concentration. So with a dilution factor of 10, 10 to the X power is equal to the starting concentration divided by the final concentration.
<h3>How do you find the dilution of a solution?</h3>
You can solve for the concentration or volume of the concentrated or dilute solution using the equation: M1V1 = M2V2, where M1 is the concentration in molarity (moles/Liters) of the concentrated solution, V2 is the volume of the concentrated solution, M2 is the concentration in molarity of the dilute solution.
