<span>the kinetic theory of heat</span>
Answer:
Cs
Explanation:
This element is the farthest right, and lowest meaning that the reactivity of it is very high.
1. valence electrons and electronegativity
2. Both reactivity and electronegativity decrease down a group.
3. Electronegativity decreases down a group, and reactivity increases down a group.
4. The number of valence electrons increases from left to right.
5. Cs

Answer:
The first one
Explanation:
- K must be calculated with the concentrations AT equilibrium, not initial concentrations.
Answer:

Explanation:
Hello!
In this case, since the relationship between energy and wavelength is defined via the speed of light and the Planck's constant as shown below:

Since c stands for the speed of light and h for the so-called Planck's constant, we can compute the wavelength as follows:

Best regards!
It is important to use the same balance throughout the entire experiment since the calibration of each balance is not the same and changing balances could result in a systematic error.
There are three types of errors that could affect the results of the experiment. The effect of random or indeterminate errors is hard to predict, its effect on the results of the experiment could be different every time. The second type of error is the systematic or determinate error, which causes a shift in results in a specific direction. The last type of error in an experiment is human error.
The type of error that could be related to the use of different balances throughout the experiment is the systematic error. Instruments could be a source of error especially if they are poorly calibrated. Also, analytical balances are calibrated differently which may result in inaccuracy in the weighing of chemicals.
