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).

Answer:

When energy is either absorbed or released, it is indicative of a chemical change. Fireworks are an example of a chemical change that produces a temperature change and emits light.

Answer:

sugar and carbon dioxide

Explanation:

Chemical energy is stored in the bonds of sugars. When the bonds of a sugar molecule are broken, a burst of energy is released that the cell can use. Cells can release energy in two basic processes: cellular respiration and fermentation. Cellular respiration requires oxygen, but fermenta- tion does not.

The secret to adding extra flavor to your Thanksgiving turkey is to season it liberally. To make sure that your favorite herbs permeate every bit of your bird, stuff a small bundle into the turkey cavity. Thyme, sage, parsley and a bit of rosemary are a great combination—but feel free to customize to your taste.

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.

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.

The specific heat capacity of the substance is calculated as follows;

Q = mcΔФ

where;

c = 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.

Explanation:

How many moles of iron are present in 3.15 × 10^24 atoms of iron?

1 mole has 6.02 X 10^23 particles

so

3.15X10^ 24 atoms =( 3.15 X 10^24)/(6.02 X 10^23) =(3.15/6.02 )X 10 =

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.

This is the electron configuration of the element carbon.

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.
