Answer: heck the chemistry app itll help you i dont know this answer but the app will tell u!
The answer is b.) Levi crosses a horse with a donkey to a create a mule. The mule is stronger than both of its parents.
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: option A) Mixtures may be composed of two or more elements, two or more compounds, or a combination of both.
Explanation:
A mixture is a combination of two or more substances mixed together and can be separated by physical methods.
A combination of two elements or compounds will yield chemical compounds NOT a mixture.
Thus, option A is false statement
Answer:
mass = 963.53 grams
Explanation:
mass = moles x molar mass
m = 9.45 x 101.96 (molar mass of Al2O3)
m = 963.53g
