KOH(aq) dissociates in water to form K+(aq) and OH-(aq).
The rate of reaction may be determined using the concentration-time graph of either a reactant or product. The slope of the graph helps in determining the rate of reaction. If the rate of reaction increases, the magnitude of the slope of the graph will increase. This indicates that more reactant is being consumed per unit time, or, in the case of the product, more product is being produced per unit time.
Answer:
2.67 × 10⁻²
Explanation:
Equation for the reaction is expressed as:
CaCrO₄(s) ⇄ Ca₂⁺(aq) + CrO₂⁻⁴(aq)
Given that:
Kc=7.1×10⁻⁴
Kc=
Kc= [x][x]
Kc= [x²]
7.1×10⁻⁴ = [x²]
x =
x = 0.0267
x =
Answer:
C A B
Explanation:
come on, you also know this from normal water waves.
which ones are stronger (= have more energy) ? the small ones or the big ones ?
and the same applies to all waves. the bigger the waves (higher amplitude), the more energy.
D. It has mass, takes up space, and can be seen without a microscope.
