If fluorine is stronger than carbon, what charge will the fluorine receive?
a. partially negative
b. partially positive
c. positive
d. negative
explain why
If fluorine is stronger than carbon, fluorine will receive a negative charge.
WHAT IS THE ELECTRONEGATIVITY SERIES?The electronegativity series is the order in which elements of the periodic table are ranked in terms of their negative charges.
Elements with higher electron affinity are positioned higher in the series. According to this question, fluorine is stronger than carbon.
This means that fluorine will receive a negative charge (-) to become more electronegative.

what happens to a pendulum’s kinetic energy as the pendulum comes to a stop.
On the other end of the swing, the kinetic energy begins to change back into potential energy. The pendulum then comes to a complete stop! At the end of each swing, it comes to a complete stop for a brief moment. When the energy is "at rest," it is once again potential energy.

To prevent inhaling spill vapors. Avoid attempting to clean up a spill if it is in an area that isn't well-ventilated. Send out a call for help to respond to and clean up the spill.
Additionally, more severe side effects include breathing problems, coughing, wheezing, a faint feeling, or weakness that may result from significant chemical exposure. The most dangerous substances can cause immediate collapse, convulsions, and possibly even death.
Wearing personal protection equipment (often known as "PPE") helps reduce exposure to a number of risks. Gloves, foot, and eye protection, protected hearing equipment (earplugs, muffs), hard helmets, respirators, and complete body suits are a few examples of PPE.

An unknown salt was dissolved to make a total 1.53g of solution. The temperature of the water decreased from
24.3C to 20.3C when 8mol were dissolved. What is the heat of solution in J/mol?
Answer:
3.213J/mol
Explanation:
first specific heat capacity of water = 4200J/Kg K
Q=mass×temperature difference×specific heat capacity
Q=1.53×(24.3-20)×4200
Q=25.704 J
heat of solution= quantity of heat ÷ amount of substance
heat of solution= 25.704÷8
heat of solution= 3.213J/mol

The combustion of c2h4(g) is represented by the equation above. (a) use the enthalpies of formation in the table below to calculate the value of δh∘1 for the reaction
Based on Hess law of constant heat summation, the enthalpy of the combustion of C2H4 can be calculated from the heat of formation values of the products CO2 and H2O.
What is a combustion reaction?A combustion reaction is a reaction between a substance and oxygen in which light and large amounts of heat is given off.
The amount of heat evolved when one mole of that substance reacts completely with oxygen is known as the enthalpy of combustion of that substance.
The equation of the combustion of C2H4 is given below:
C2H4 + 3 O2 ---> 2 CO2 + 2H2OThe enthalpy of the combustion of C2H4 can be calculated from the heat of formation of the products CO2 and H2O based on Hess law.
