Answer:
They all do. If you throw them off a building and watch them shatter.
Explanation:
Answer: 3.42 L
Explanation:
Molarity equation = moles / L
.35 M = 1.2 mol / L
volume = 3.42 L
In the electrolysis of molten BaI₂, the product forms at the cathode Barium metal (Ba).
First ionic bonds in this salt are separated because of heat:
BaI₂(aq) → (aq) + I⁻(aq).
Reaction of reduction at cathode(-):
(aq) + 2e⁻ → 2Ba(s)
turns into Ba metal.
Reaction of oxidation at anode(+):
2I⁻(aq) → I₂(g) + 2e⁻.
So I⁻ turns into I₂(g)
The anode is positive and the cathode is negative.
In chemistry, the type of process in which decomposition of a chemical substance occurs due to the flow of electricity through the substance is generally known as the electrolysis process. Usually, the electrolysis process becomes in an arrangement in which one electrode of the cathode and one electrode of the anode are present.
In chemistry and production, electrolysis is a technique that makes use of direct electric present-day (DC) to power an otherwise non-spontaneous chemical response.
Electrolysis is commercially crucial as a degree inside the separation of factors from clearly going on sources including ores the usage of an electrolytic cell.

Answer:
A number of other chemists before Mendeleev were investigating patterns in the properties of the elements that were known at the time. The earliest attempt to classify the elements was in 1789, when Antoine Lavoisier grouped the elements based on their properties into gases, non-metals, metals and earths. Several other attempts were made to group elements together over the coming decades. In 1829, Johann Döbereiner recognised triads of elements with chemically similar properties, such as lithium, sodium and potassium, and showed that the properties of the middle element could be predicted from the properties of the other two.
It was not until a more accurate list of the atomic mass of the elements became available at a conference in Karlsruhe, Germany in 1860 that real progress was made towards the discovery of the modern periodic table. This area of the website celebrates the work of many famous scientists whose quest to learn more about the world we live in and the atoms that make up the things around us led to the periodic table as we know it today.

Answer:
The amount of glue used, the material and how much of it you're using every time you test each glue, the temperature of the room, etc.
Explanation:
There are many answers to this question but think about the obvious ones first. Obviously you'll need to use the same amount of glue every time you're testing each type. The material used is also important and how much of the material you're using because different types of glue can work better with different materials, as well as how much material you're using. The temperature of the room can affect how well each glue holds up because often glue dries easier/quicker with heat, so in your experiment to make it fair you need to make sure that each glue is tested in the same environment.
