Beryllium oxide is heated.
What is the chemical reaction equation?
Answer:
BeO
Reaction of beryllium with air
However, powdered beryllium metal does burn in air to give a mixture of white beryllium oxide, BeO, and beryllium nitride, Be3N2. Beryllium oxide is more normally made by heating beryllium carbonate. 2Be(s) + O2(g) → 2BeO(s)
**PLEASE HELP** If you were presented with a preserved brain specimen, but weren’t told whether it was from a human or a sheep, how would you determine which animal it was from? Describe at least three differences you would use to help determine your answer.
Answer:
size-humans brains are usually larger than animals, shape-some animal brains are shaped very odd, and the cerebrum-that is the part of the brain that makes us human.
The three difference between animal brain and human brain will be state out on the basis of size, shape and number of folds.
What is brain?Brain is the main central part of the nervous system of all organism present in the earth.
Three differences between the structure of human brain and animal brain.
Size of the human brain is generally larger than the animal brain.Shape of the brains for humans and animals are different as they both have differnt folds in that.Cerebrum is present only in mammals, so that some animals will not have cerebrum.Hence three differences between human and animal brains are listed above.

Describe two patterns in the periodic table?
Answer:
Patter 1: Ionization Energy Decreases going down a group
Pattern 2: Ions tend to gain/lose the least amount of electrons
Take oxygen, for example. Oxygen has 8 electrons. To become like a noble gas it could either gain two to become like neon or it could lose six to become like helium. So what will oxygen do—gain two or lose six? As a general rule, atoms will gain or lose the fewest number of electrons possible.

What volume of 9.0 M copper (II) sulfate stock solution is needed to prepare 3.0 L of a 5.0 M solution?
Answer:
The volume of 9.0 M copper (II) sulfate stock solution needed to prepare 3.0 L of a 5.0 M solution is 1.667 L
Explanation:
Dilution is a process by which the concentration of a solute in solution is reduced by adding more solvent.
In other words, dilution is the procedure followed to prepare a less concentrated solution from a more concentrated one, and it simply consists of adding more solvent.
In a dilution the amount of solute does not vary. What varies in a dilution is the volume of the solvent: as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.
The equation used in this case is:
Ci * Vi = Cf * Vf
where
Ci: initial concentration Vi: initial volume Cf: final concentration Vf: final volumeIn this case:
Ci: 9 M Vi: ? Cf: 5 M Vf: 3 LReplacing:
9 M*Vi= 5 M* 3 L
Solving:
[tex]Vi=\frac{5 M*3 L}{9 M}[/tex]
Vi= 1.667 L
The volume of 9.0 M copper (II) sulfate stock solution needed to prepare 3.0 L of a 5.0 M solution is 1.667 L

Using the same sample of gas (P = 475 torr , T = 21 °C ), we wish to change the pressure
to 4750 torr with no accompanying change in volume or amount of gas. What temperature T2 in
Celsius, is needed to reach this pressure?
Answer:
210°C
Explanation:
using the equation
P1/T1=P2/T2
475/21=4750/T2
T2= (21×4750)/475
T= 210°C

What hold elements together to form compounds
Answer:
Chemical bonds are forces that hold elements together. it can be either covalent or ionic bonds that are these chemical bonds.
(03.03 LC)
Which of the following describes a covalent bond?
Answer:
It is the sharing of electrons between atoms with an electronegativity difference below 1.7.
Explanation: Covalent bond is the bond which is formed with the sharing of the electrons between the two atoms which are taking part in the bond.
Answer: Covalent bond, in chemistry, the interatomic linkage that results from the sharing of an electron pair between two atoms. The binding arises from the electrostatic attraction of their nuclei for the same electrons.
Explanation: A covalent bond forms when the bonded atoms have a lower total energy than that of widely separated atoms.
