How do the atoms aluminum and fluorine react to form the compound aluminum fluoride?
Answers
Answer:
Aluminum fluoride is an ionic compound. Meaning that the two elements form a ionic bond. In ionic bonding, atoms receive and donate electrons in order to become stable. In this case, aluminum donates its three outer electrons to three fluorine atoms. Aluminum forms a triple positive aluminium ion (Becomes a cation) and fluorine forms three single negative fluoride ions (Becomes a anion).

A student graphed the position of a cart during a 7-second time interval.
Which statement best describes the cart?
A.
The cart was stationary except for a short burst of acceleration of 0.5 m/s².
B.
The cart accelerated at a constant rate of approximately 0.8 m/s².
C.
The cart was stationary with a velocity of 0 m/s for the entire 7 seconds.
D.
The cart moved at a constant velocity of 0.5 m/s for the entire 7 seconds.
Answers
Answer: D the cart moved at a constant velocity of 0.5m/s for the entire 7 seconds.
The cart accelerated at a constant rate of approximately 0.8 m/s². Option (B) is correct.
Option B is the best description based on the graphed position data during the 7-second time interval. The cart's acceleration can be determined by analyzing the shape of the position-time graph.
If the cart was stationary, the position-time graph would be a horizontal line (option C). If the cart moved at a constant velocity, the graph would be a straight line inclined at a constant angle (option D).
However, the graph likely shows a curved line, indicating changing position over time. This suggests that the cart experienced acceleration. To further confirm, calculate the acceleration:
Acceleration (a) = Δv / Δt,
where Δv is the change in velocity and Δt is the change in time.
Given the time interval is 7 seconds, and the initial and final velocities are likely different, you can calculate the average acceleration. If the average acceleration is approximately 0.8 m/s², then option B is correct.
The graphed data aligns with the scenario of constant acceleration, supporting option B.

1. What is the specific heat of a substance that requires 270 J of energy to raise the temperature of 4.2 grams by 25°C?
Answers
Heat required is mcΔT=100×0.39×50=1950 J
Solve any question of Thermodynamics with:-
The specific heat of the substance that requires 270 J of energy to raise the temperature is 2.57 J/g⁰C.
Specific heat capacity of the substanceThe specific heat capacity of the substance is calculated as follows;
Q = mcΔФ
where;
c is the specific heat capacityc = Q/mΔФ
c = (270) / (4.2 x 25)
c = 2.57 J/g⁰C
Thus, the specific heat of the substance that requires 270 J of energy to raise the temperature is 2.57 J/g⁰C.

In an AP Chemistry laboratory, students were given two unlabeled beakers and told that one of the beakers contained 1.0g of solid CaCO3 and the other contained
1.0g of solid AgNO3. They were told to devise an experiment to identify which compound was which. A student did so by adding 50 mL of distilled water to each beaker. Describe the student's observations that allowed him to identify each compound.
Answers
When the student adds 50 mL of distilled water to each beaker, CaCO3 will not dissolve in water while AgNO3 will dissolve completely in water.
We have to recall that according to the solubility rules, the carbonates of group two elements are insoluble in water. The solubility rules offer a convenient way of predicting the solubility of a compound in water.
When the student adds 50 mL of distilled water to each beaker, CaCO3 will not dissolve in water while AgNO3 will dissolve completely in water. This is because, the carbonates of group two elements are insoluble in water.

how many electrons does hydrogen need in order to have a full shell of valence electrons?
Answers
Answer:
One
Explanation:
In a hydrogen atom, the first outer shell only consists of two valence electrons, because it would already have one, the atom only needs one more.
It requires two electrons to completely occupy its outer shell, it frequently forms a single covalent bond with another atom. Because of this configuration, hydrogen can gain access to two electrons and completely occupy its valence shell.
What is Hydrogen?Hydrogen adheres to the duet rule because it only requires two electrons to completely occupy its valence shell. It deviates from the octet rule. Hydrogen only needs to form one bond. Because of this, H is always a terminal atom and never a central atom. Hydrogen is a chemical element with the symbol H and the atomic number 1.Hydrogen is the lightest element. Under normal conditions, hydrogen is a gas of diatomic molecules with the formula H2. It is colorless, odourless, tasteless, non-toxic, and extremely flammable. Hydrogen is a more environmentally friendly alternative to methane, also known as natural gas. It is the most abundant chemical element, accounting for 75% of the universe's mass. Water, plants, animals, and, of course, humans contain massive amounts of hydrogen atoms.To learn more about valence electron refer to:
