(4) the same quantity of charge and the opposite sign
Protons, neutrons, and electrons are generally called subatomic particles. They are important components for building atoms. Each atom has a different number of protons, neutrons, and electrons. And ask how the atom maintains its identity and uniqueness. They have different charges and different masses. Also, the role of each subatomic particle is very different from each other. The main difference between Protons, Neutrons, and Electrons can be found in the charge. Protons are positively charged and neutrons are neutral while electrons are negatively charged.
Protons are positively charged. The charge, in this case, is determined by the number of coulombic charges an electron has. The charge of a proton is the same as loading an electron and, approved, can be expressed as 1e. (1e = 1,602 * 10 ^ (- 19) C).
Protons, along with neutrons, are called "nucleons." There are one or more protons in each atom. The number of protons is different in each atom and makes the identity of the atom. When elements are grouped together in a periodic table, the number of protons is used as the atomic number of the element.
Electrons are the third type of subatomic particles, and they are found to orbit around the nucleus in discrete energy levels with discrete. Just like the number of protons, the number of electrons in an atom which carries the identity of each element. The way electrons are published in each element is expressed by their electronic configuration. The number of electrons is similar to the number of protons found in an element. The electron is symbolized as 'e.' Electrons are the only subatomic particles that take part in chemical reactions. They also take part in certain reproductive reactions.

the balanced chemical equation for decomposition of HgO is as follows
2HgO --> 2Hg + O₂
stoichiometry of HgO to O₂ is 2:1
number of HgO moles heated are - 3.00 g / 216.59 g/mol = 0.0139 mol
according to stoichiometry of reaction -
number of O₂ moles formed = 0.0139 mol/ 2 = 0.00695 mol
mass of O₂ to be formed - 0.00695 mol x 32.00 g/mol = 0.2224 g
but the actual yield = 0.195 g
percent yield = actual yield / theoretical yield x 100 %
percent yield = 0.195 g / 0.2224 g x 100 % = 87.7 %
answer is 87.7 %
Answer:
The correct answer is 87.8%
Answer:
Genes are segments of DNA that contain the code for a paticular protein that works in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Answer:
The answer to your question is 68 g
Explanation:
Data
mass of H₂ = 12 g
mass of NH₃ = ?
Balanced chemical reaction
3H₂ + N₂ ⇒ 2NH₃
Process
1.- Calculate the molar mass of H₂
H₂ = 1 x 6 = 6
NH₃ = 2[(14 x 1) + (3 x 1)]
= 2[14 + 3]
= 2[17]
= 34 g
2.- Use proportions to find the mass of NH₃
6 g of H₂ --------------- 34 g of NH₃
12g of H₂ ---------------- x
x = (12 x 34) / 6
x = 408/6
x = 68 g of NH₃
The question given above is not complete, the options attached to the question is given below:
A). Putting them in a deep pool of water
B). Burying them in a deep underground storage facility
C). Sending them on the shuttle to be suspended in space
D). Putting them in concrete/lead casks and sitting at thereactor site
ANSWER
The correct option is C.
There are many ways of storing spent nuclear fuel rods, these include: immersing them in deep pool of water, storing them in lead casks and burying them in deep underground storage. These forms of storage are utilized in order to protect people and the environment from the harmful radiations that radiate from these fuel rods. Spent fuel rods must never be exposed, therefore it is not possible to suspend them in space.
Answer:
c
