If more heat is removed from the reaction the rate of reaction change as below to counter the action
The rate of the <em>forward reaction increase</em> and produces more <em>zinc chloride</em>
<u><em> explanation</em></u>
- <u><em> </em></u>The reaction of zinc and HCl to produce ZnCl and H2 <u><em>is </em></u> exothermic reaction, heat is produced as one product and by removing heat it favor forward reaction
- The position of equilibrium moves to the right since removing heat led to decrease of temperature and more zinc chloride is produced.
Answer:
Frequency = 0.6 × 10¹⁵ s⁻¹
Explanation:
Given data:
Wavelength = 5.32 × 10⁻⁷ m
Frequency = ?
Solution:
Formula:
speed of light = wavelength × frequency
Frequency = speed of light / wavelength
Frequency = 3 × 10⁸ m/s / 5.32 × 10⁻⁷ m
Frequency = 0.6 × 10¹⁵ s⁻¹
Answer:
B.Number of times a person can squeeze a clothespin
Explanation:
Hello,
Since the idea is to detect the effect of the previous exercise on the number of times a person can squeeze a clothespin and this is done by setting a specific time of 1 minute (a controlled variable) and subsequently record the times, one can state that the times the clothespin is squeezed depend both on the type of exercise and the time, thus those times turn out into the dependent variable.
Best regards.
