The Zn atom in Zn(CIO3)2 will be 1.
A chemical element however is uniquely defined by its atoms, which are tiny pieces of substance. An atom is made up of a core nucleus and one or perhaps more electrons with negative charges that orbit it. The positively charged, comparatively hefty protons and neutrons that make up the nucleus may be present.
The given chemical formula is :
Zn(CIO3)2
The number of Zn = 1
The number of Cl atom = 2
The number of O = 6
Hence, it can be said that there are 1 atom of Zn present in the Zn(CIO3)2 .
Therefore, the correct answer will be option (A)

ILL GIVE YOU BRIANLIEST! PLEASE HELP: Every compound is a molecule, but every molecule is not a compound. Why is this? Give an example with your answer.
Answer:
This is because some molecules contain only one chemical element, and a compound, by definition, contains 2 or more elements.
Explanation:
Consider molecular Hydrogen (H₂) as an example. It is a molecule, albeit very simple, because it is made up of multiple atoms (2 Hydrogen atoms, to be precise). It is not a compound, however, because it only contains one chemical element: Hydrogen.
what kind of metal is bronze? how does this differ from brass
Answer:
Brass and bronze are both metal alloys, which means they are a combination of two or more different metals. Brass is composed of copper and zinc, whereas bronze is made up of copper and tin, sometimes with other elements such as phosphorus or aluminium added in.
Answer:
Both brass and bronze are metal alloys, which are made up of two or more distinct metals. Brass is comprised of copper and zinc, while bronze is formed of copper and tin, with the addition of phosphorous or aluminum.

Lead has a density of 11.4 grams per mL. If I make a statue out of 3.78 grams of lead, what is the statues volume
Answer:
0.332mL
Explanation:
11.4g/mL is 11.4 for every one mL
11.4g / 1mL needs to be the same ratio as 3.78g to an unknown value, let's call it x.
11.4g/1mL = 3.78g/x
We cross multiply: 1*3.78 = 11.4*x
3.78 = 11.4x
Now isolate x by diving 11.4 on both sides: 0.331578974mL = x
In chemistry, we usually round to significant figures, so our answer would be 0.332mL
identify ways to reduce the risk of liquid bumping while heating.
The most common way of preventing bumping is by adding one or two boiling chips to the reaction vessel. However, these alone may not prevent bumping and for this reason it is advisable to boil liquids in a boiling tube, a boiling flask, or an Erlenmeyer flask.

what is the difference between thermal energy and heat ?
There is really no difference thermal energy and heat are pretty the same thing.
Answer:
Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy.

Why does the total mechanical energy stay the same as kinetic and potential energy change?
total mechanical energy is the sum of kinetic energy and potential energy so it will remain same always
Answer:
Explanation:
Because the kinetic and potential energy are constant. A good example of kinetic and potential energy are throwing a ball up. It leaves your hand with kinetic energy. When it reaches the top it doesn’t have any kinetic force but potential energy equal to the kinetic energy the ball had when you threw it up. And, when it comes back to your hand it has the same kinetic energy it had when it left your hand. Thus, the sum of the kinetic energy plus potential energy is a constant.
is stretching a rubber band endothermic or exothermic
Answer:
exothermic
Explanation:
take a rubber band between the first two finger of each hand
stretch it, release, stretch is release over and over fast
put the rubber band on you cheek and feel the heat
You RELEASED HEAT, HEAT CAME OUT, HEAT EXITED THE RUBBER
so the process is EXO(EXITS)-THERMIC (HEAT)

Straw house: 5 feet
Explanation:
Look at the window on the left side of the simulation. It shows the reaction A + BC ⇌ AB + C. How does this reaction differ from the reaction by which ammonia is synthesized?
Answer:
A + BC → AB + C "single replacement reaction" while ammonia synthesis is a "synthesis reaction".
Explanation:
A single replacement reaction, is a reaction by which one element replaces an/other element in a compound.
It can be represented generically as: A + B-C → A-C + B This will most often occur if A is more reactive than B, thus giving a more stable product.
A synthesis reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product. The reactants may be elements or compounds, while the product is always a compound.
Example: ammonia synthesis,
N₂ + 3H₂ ⇄ 2NH₃
