The answer is [OH⁻] = 1 x 10⁻⁸.
To find OH⁻, divide the ionic product of water by [H₃O⁺] as :
<u>OH⁻ + H₃O⁺ = H₂O</u>
<u />
- [OH⁻] = 1 x 10⁻¹⁴ / 1 x 10⁻⁶
- [OH⁻] = 1 x 10⁻⁸
Answer:
C
Explanation:
Na has an electron configuration of 2,8,1
it forms an ion by losing 1 electron thus gaining a 1+ charge
One can only hold 2 electrons which only means shell two can hold 8, and for the first eighteen elements shell three can hold a maximum of eight electrons
Answer:
Decomposition Reaction
2 AgCO₃ -----> 2 Ag + 2 C + 3 O₂
Explanation:
During the reaction, the reactant breaks down into smaller elements/compounds. As such, this is a decomposition reaction.
An equation is balanced when there is an equal amount of each element on both sides of the reaction. If these amounts are unequal, you can add coefficients to modify the quantities of particular elements/compounds. These coefficients must be as small as they can be while remaining whole numbers.
The unbalanced equation:
AgCO₃ -----> Ag + C + O₂
<u>Reactants</u>: 1 silver, 1 carbon, 3 oxygen
<u>Products</u>: 1 silver, 1 carbon, 2 oxygen
The balanced equation:
2 AgCO₃ -----> 2 Ag + 2 C + 3 O₂
<u>Reactants</u>: 2 silver, 2 carbon, 6 oxygen
<u>Products</u>: 2 silver, 2 carbon, 6 oxygen
Answer:
depending on what school you go to and what classes you are allowed to take in which grades, you should take forensics.
