Neutrons don't have a charge. They are neutral
Taking into account the definition of ato, proton, neutron and electron, the correct answer is second option: The one particle that does NOT have a charge is the neutron.
You must know the atom is defined as the smallest particle into which an element can be divided without losing its chemical properties.
Atoms are made up of extremely small particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom and form the nucleus, while electrons surround the nucleus.
Electrons have a negative charge, while the charge of protons is positive. The only ones that have no electrical charge are neutrons.
In this way, the atomic nucleus has a positive charge in which almost all its mass is concentrated, while around the atomic nucleus, there are a certain number of electrons, negatively charged.
Finally, the correct answer is second option: The one particle that does NOT have a charge is the neutron.

What do the elements within a "period" have in common?
The number of atomic orbitals is the same for all elements in a period. Every element in the top row (the first period), for example, has only one orbital for its electrons. The electrons of all the elements in the second row (second period) have two orbitals. Every row adds an orbital as you progress down the table.

Some power plants burn coal to produce electricity the energy released from the cold being burned is used to change water into steam steam spinach turbines of large generators that produce electricity which energy transformations occur when coal is used to produce electricity
Answer:
When coal is used to produce electricity , the heat energy is transformed into mechanical energy .
Explanation:
Coal is one of the United States' most affordable and largest domestically produced energy sources. It is used to generate a significant quantity of our electricity, about 37%. Historically, producing power from coal has been correlated with a wide range of environmental impacts.
Water is converted into steam at a coal-fired steam plant, much like a nuclear plant, which in turn powers turbine generators to generate electricity. Here is how it operates in the process.
Heat is produced -: It is pulverized to the fineness of talcum powder until the coal is burnt. It is then combined with hot air and blown into the boiler's firebox. The coal / air mixture provides the most full combustion and optimum heat necessary for suspension burning.Water transforms to vapor -: The heat turns highly purified water, pumped through pipes inside the boiler, into steam. The steam is piped to the turbine, reaching temperatures of up to 1,000 degrees Fahrenheit and pressures of up to 3,500 pounds per square inch. The Engine Transforms Steam -: The turbine shaft is rotated by the immense stress of the steam pressing against a pair of giant blades. The turbine shaft is attached to the generator shaft, where magnets spin to generate electricity within wire coils.Steam switches back to water -: The steam is drawn into a large chamber in the basement of the power plant after doing its job in the turbine. Millions of gallons of cool water from a nearby source (such as a river or lake) are pumped through a network of tubes that pass through the condenser in this significant stage. In the tubes, the cool water turns the steam back into water that can be used in the plant over and over again.Without any pollution, the cooling water is returned to its source and the steam water is returned to the boiler to repeat the cycle.
Hence, the heat energy is transformed to the mechanical energy ,when coal is used to produce electricity.

Answer:
[tex]\huge\boxed{\sf 186.59\ L}[/tex]
Explanation:
Given that:
No. of moles = 8.33 mol
At STP, 1 mol. of all gases has a molar value of 22.4 dm³/mol
So,
Volume of 8.33 mol of N₂ gas:
= no. of moles x molar value
= 8.33 x 22.4
= 186.59 dm³
Since 1 dm³ = 1 L
So,
Volume = 186.59 L

What mass of nitrogen is required to react with 5. 04 grams of oxygen?
The mass of nitrogen, N₂ required to react with 5.04 grams of oxygen O₂ is 1.76 grams
Balanced equation2N₂ + 5O₂ —> 2N₂O₅
Molar mass of N₂ = 2 × 14 = 28 g/mol
Mass of N₂ from the balanced equation = 2 × 28 = 56 g
Molar mass of O₂ = 2 × 16 = 32 g/mol
Mass of O₂ from the balanced equation = 5 × 32 = 160 g
SUMMARY
From the balanced equation above,
160 g of O₂ reacted with 56 g of N₂
How to determine the mass of N₂ requiredFrom the balanced equation above,
160 g of O₂ reacted with 56 g of N₂
Therefore,
5.04 g of O₂ will react with = (5.04 × 56) / 160 = 1.76 g of N₂
Thus, 1.76 g of N₂ is needed for the reaction
