C. Fluorine with an electronegativity of 4.0
We can actually deduce here that the important points to consider when conducting the described data collection are:
- The exact temperature at which the crickets chirped less.
- The exact temperature the crickets chirped more.
- Other forces that influence the chirping of the crickets e.g: weather condition, human factor, environmental noise, etc.
<h3>What is data collection?</h3>
Data collection is actually known to be the process of collecting data, information or statistics for the purpose of research and documentation.
Data collection is actually important when research projects are being carried out.
We see that it is very important to note that when carrying out the data collection in Pinky's science fair project, the above important points should be noted or observed.

Answer:
The specific heat capacity is 0.67
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
The amount of heat that a body receives or transmits is determined by the following expression:
Q = c * m * ΔT
Where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
This expression indicates that between heat and temperature there is a direct proportional relationship.
In this case:
- Q= 100 J
- c= ?
- m= 5 g
- ΔT= Tfinal - Tinitial= 40 °C - 10 °C= 30 °C
Replacing:
100 J= c*5 g* 30°C
Solving:
c= 0.67

Answer:
58.32
Explanation:
The mass number is one mole and for Mg it is 24.306 for O it is 15.999 and for H it is 1.008. because O and H have 2, you multiply them by 2 and add all the numbers and it equals 58.32
