Answer:
If liquid bromine is cooled to form a solid, which type of solid does it form? Brass is made by melting copper and zinc and physically mixing them. As this alloy is cooled, it forms a solid where the copper and zinc are not chemically bonded together.
Explanation:
Answer:
Earth's atmosphere is divided into five main layers: the exosphere, the thermosphere, the mesosphere, the stratosphere and the troposphere.
Explanation:
Here are my reasonable beliefs
For number 1. what the answer seems to be is C.Than looking are numbers two and three their answers are both B
My reasoning for them is , because if you think about the solid liquid gas's this is a common result in most experiments.also for number two , you have to decrease ( go down ) on the concentration ( hardness ) of the subject to get a more powerful solution
So far as number one , for it to be water the atoms have to be far away from the other moving freely , to be a solid they can barely move at all.
Answer:
The answer is Nitrogen has a larger radius and one less proton than oxygen.
Explanation:
Nitrogen is a gas and gas expands to fill up an area so oxygen would be pushed out and the Nitrogen would take over.
Answer:
Explanation:
2Ca is the elemental form of calcium. There are 2 mols of calcium in whatever equation you are talking about.
Ca_2 means that there are 2 ions of Calcium making up something like
Ca3(PO4)2 means that you have the compound Ca3(PO4)2 with 2 mols of PO4 and 3 moles of Ca
It is hard to come up with something composed of Ca2 because unless the other ion is odd, the 2 will divide into something.
