1: An atom is nuclear energy that is extremely small. It is the smallest unit of matter that forms a chemical element. It is the building block for all matter in the universe. They are made up of even smaller particles. Particles that make up an atom are electrons, neutrons, and protons.
2. What’s different inside of an atom to make them into different elements is that the number of protons in an atom is the defining feature of an atom. This is what makes a element different from another.
Hope this helps!!
Answer:
The measured absorbance will be too large.
Explanation:
Fe³⁺(aq) + SCN⁻(aq) ⟶Fe(SCN)²⁺(aq)
A = log₁₀(I₀/I)
If the student orients the cuvette so that the path of the light is through the frosted sides of the cuvette, little light will be able to reach the detector.
The measured intensity (I) will be quite small, so the absorbance (A) will be unusually large.
The given reaction is
2Li₂O₂(s) ⇄ 2Li₂O(s) + O₂(g)
The equilibrium constant for the specified reaction will be because the concentrations of solids and pure liquids are not taken into account in the expression of the equilibrium constant:
K=[O 2 ]
The reaction reaches equilibrium when Li₂O₂ is added at the conclusion of the reaction, ensuring that the amount of O₂ remains constant or unchanged.
What is thermal decomposition?
Thermolysis, also known as thermal decomposition, is a chemical decomposition brought on by heat. The temperature at which a substance decomposes chemically is known as the decomposition temperature of the substance. Since heat is necessary to break the chemical bonds in the substance that is undergoing breakdown, the process is typically endothermic.

Answer:
mass of water in hydrate = 2.37 grams
Explanation:
The mass of the hydrated cobalt (III) chloride is the summation of the salt and the water it contains.
This means that:
Total mass of sample = mass of salt + mass of water
Now, we are given that:
total mass of sample = 5.22 grams
mass of salt = mass of sample after heating = 2.85 grams
Substitute to get the mass of water as follows:
5.22 = mass of water in hydrate + 2.85
mass of water in hydrate = 5.22 - 2.85
mass of water in hydrate = 2.37 grams
Hope this helps :)
