Why does a light bulb turn in When you flip the switch to on?
Explanation:
Flipping a light switch to turn on a light means that the circuit with the light is being closed. When the switch is flipped the opposite way, to turn the light off, the circuit is being opened.
Answer:
You now have an open circuit
Explanation:
The circuit is closed when the switch is flipped the other way to turn off the light.
How did the Heisenberg uncertainty principle contribute to the idea that electrons occupy “clouds," or "orbitals”?
Answer:
Because the exact position of the electron is not known,it must be assumed that the electron takes up the entire space in an orbital.

Magnesium Chloride is used as a precursor magnesium metals.
Explanation:
pls answer this it's due today
Answer:
That's pretty easy,if you have a grasp of Elements, Compounds and their Symbols ans Molecular formula.
So, Let's get started!
Our reactions are as follows:
Sodium(Na) + Chlorine(Cl) ---> Sodium chloride(NaCl)Think of a compound that has both Sodium and Chlorine and is very common.
Common salt — Sodium chloride!
Yeah, that's it! It has both Sodium and Chlorine in it's molecular formula. (NaCl)
Magnesium(Mg) + Oxygen(O2) ---> Magnesium oxide(MgO)Now, we have to, somehow, get Magnesium oxide using Oxygen. The best way is: by reacting Magnesium with Oxygen.
Iron(Fe) + Sulfur(S) ---> Iron Sulfide(FeS)Now, we have to get two reactants that react to form Iron Sulfide.
FeS contains only two elements in its formula and that are: Iron(Fe) and Sulfur(S).
So, the best way would be to react Iron(Fe) and Sulfur(S) and get Iron Sulfide (FeS)
Hydrogen(H2) + Oxygen(O2) ---> water(H2O)You must know that water is H2O, that is, a compound of Hydrogen and Oxygen, the easiest way to get H2O as your product would be : by reacting Oxygen and Hydrogen.
what type of elements form ionic bonds with metals
Answer:

Explanation:
When magnesium ium is left in moist air for several hours, the metal Sur face taanishes?why
Answer:
due to the formation of an oxide or hydroxide layer
Explanation:
magnesium is a reactive metal...when left in air it reacts with oxygen to form an oxide layer of MgO and it can react with moisture to form Mg(OH)2 LAYER ON THE SURFACE.
Use the Periodic Table to find molar mass of water. Sodium hydroxide (NaOH) and hydrochloric acid (HCl) react to form sodium chloride (NaCl) and water according to the equation: NaOH HCl → NaCl H2O What mass of water forms when 2. 75 Ă— 10â€""4 mol NaOH reacts completely? 2. 75 Ă— 10â€""4 mol NaOH = g H2O.
Considering the reaction stoichiometry, 0.00495 grams of water is produced when 2.75×10⁻⁴ moles of NaOH reacts completely.
Sodium hydroxide (NaOH) and hydrochloric acid (HCl) react to form sodium chloride (NaCl) and water. So, the balanced reaction is:
NaOH + HCl → NaCl + H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
NaOH: 1 moleHCl: 1 moleNaCl: 1 moleH₂O: 1 mole
In the periodic table, you can find the molar mass of the elements, also called atomic mass or atomic weight. So, to calculate the molar mass of a compound, you must add the molar mass of the elements of the compound multiplied by the times they appear in the compound.
So, in the case of water:
H₂O= 2× 1 g/mole + 16 g/mole
H₂O= 18 g/mole
Then, if by stoichiometry of the reaction 1 mole of water is produced, the mass of water produced is calculated as:
mass H₂O= 1 mole× 18 g/mole
mass H₂O= 18 g
Then you can apply the following rule of three: if by stoichiometry 1 moles of NaOH produce 18 grams of H₂O, 2.75×10⁻⁴ moles of NaOH will produce how much mass of H₂O?
[tex]mass of H_{2} O=\frac{2.75x10^{-4} moles of NaOHx18 grams of H_{2} O}{1 mole of NaOH}[/tex]
mass of H₂O= 0.00495 grams
In summary, 0.00495 grams of water is produced when 2.75×10⁻⁴ moles of NaOH reacts completely.

A. The addition of sodium metal to water.
B. The addition of sulfur dioxide gas to water.
C. Burning sodium metal in chlorine gas.
D. The addition of chlorine gas to a solution of potassium iodide.
Answer:
the addition of chlorine gas to a solution of potassium iodide.
The reaction that produces a colored substance is the addition of chlorine gas to a solution of potassium iodide. The correct option is D.
What is a chemical reaction?In a chemical reaction, reactants undergo a chemical reaction and transform into products through a chemical process. For instance, when humans breathe in oxygen, it combines with glucose to create carbon dioxide, water, and energy.
Another sign that a chemical reaction has taken place is a change in color. If two solutions are combined and a color change occurs that is not just the effect of diluting one of the reactant solutions, a reaction has taken place. A solid and a liquid combined may also result in a change in color.
Therefore, the correct option is D. The addition of chlorine gas to a solution of potassium iodide.

Why is there a large difference between day and night temperatures in a desert?
All rainfall in a desert happens at night.
There are no plants to trap the heat.
Heat escapes rapidly at night because the air is so dry.
The ground absorbs all heat. 20 points :,)
Answer: Heat escapes rapidly at night because the air is so dry.
Explanation: The desert has little humidity and rarely is cloudy. These two factors allow the desert to heat up rapidly during the day and cool off quickly at night.

why does fluorine have the highest electronegativity
Answer:
Because it only needs one more electron to get to a full valence shell (8), so it really wants it and is pulling other electrons in. It also has to do with needing one more electron to fill the 2p shell. It is a small element which means its electrons are pulled tightly to the nucleus.

How does temperature affect winds all
over the globe?
Answer:
The differences in atmospheric pressure generate winds.
Explanation:
At the Equator, the sun warms the water and land more than it does the rest of the world. Warm equatorial air rises higher into the atmospher and migrates towards the poles. The complex relationships between fronts cause different types of winds and weather patterns.
