22 because that how many days it will take for the exact moon shape to pass and it will then reappear.
Answer: 6100 seconds
Explanation: 6.1 Kiloseconds = 6100 Seconds
Answer:
The correct answer is C.
Explanation:
The reaction speed remains constant in region C. This is because the growth rate decreases, tending to zero. Graphically you can see how the slope of the tangent line approaches the horizontal. The slope of the tangent line represents the rate of reaction speed. It is constant because although the concentration continues to increase, the reaction rate does not vary.
Have a nice day!
A.
This is because BaSO₄ has the lowest solubility product out of all the substances.
Strong electrolytes by definition are those compounds that completely dissociates into their component ions when dissolved in water. The chemical formula for the zinc fluoride is,
ZnF2
This means that each formula unit is composed of one atom of zinc and 2 atoms of fluoride. The ions comprising the unit are Zn²⁺ and F⁻. The dissociation is as shown below,
ZnF₂ --> Zn²⁺ + 2F⁻
When dissolved in water it is expected that the compound dissociates into three different ions, one Zn²⁺ and two F⁻.
