How does the generator work? Select the statement that describes that.
It turns electrical energy into KE.
This is the correct statement of how a generator works:
What is generator?A generator is described as a device that converts motive power or fuel-based power into electric power for use in an external circuit.
Generators contrary to general opinion do not create electricity instead it uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit. This flow of electrons makes up the output electric current supplied by the generator.
The present-day generators work on the principle of electromagnetic induction that was discovered by Michael Faraday.
Faraday realized that the above flow of current can be created by moving an electrical conductor in a magnetic field and this movement creates a voltage difference between the two ends of the conductor which causes the electric charges to flow, hence generating electric current.

A sample of gas contains 0.1500 mol of N2(g) and 0.3000 mol of H2(g) and occupies a volume of 16.2 L. The following reaction takes place:
N2(g) + 2H2(g)N2H4(g)
Calculate the volume of the sample after the reaction takes place, assuming that the temperature and the pressure remain constant.
The volume of the sample after the reaction takes place at constant temperature and pressure would be 5.4 L.
Volume of gases at constant temperature and pressureIn the reaction: [tex]N_2(g) + 2H_2(g)-- > N_2H_4(g)[/tex]
Stoichiometrically, 1 mole of [tex]N_2[/tex] reacts with 2 moles of [tex]H_2[/tex] to produce 1 mole of [tex]N_2H_4[/tex].
In reality, 0.1500 mol of [tex]N_2[/tex] reacts with 0.3000 mol of [tex]H_2[/tex]. The equivalent amount of [tex]N_2H_4[/tex] that would be formed will be 0.1500 mol according to the mole ratios from the balanced equation of the reaction.
Now, at constant temperature and pressure:
0.1500 + 0.3000 = 0.4500 mol
0.4500 mol is equivalent to 16.2 L according to the illustration.
0.1500 mol of [tex]N_2H_4[/tex] is produced, the equivalent mole would, therefore, be:
0.4500 mol = 16.2 L
0.1500 mol = 16.2 x 0.1500/0.4500
= 5.4 L
In other words, the volume of the sample after the reaction takes place at constant temperature and pressure would be 5.4 L.

Which statement correctly explains how matter is conserved in chemical reactions?
The statement which correctly explains how matter is conserved in chemical reactions is- Atoms of each element are conserved, so the total mass does not change.
The Law of Lomonsov-Lavoisier and the Law of Conservation of Mass are other names for the Law of Conservation of Matter. "The mass is not generated or destroyed, simply altered," according to this law.
As a result of the diverse atomic arrangements in the various substances, the reagents interact with one another to create new products that differ from the reagents in terms of their physical and chemical characteristics. But the amount of matter or mass before and after a transformation (chemical reaction) must always be constant; that is, the amounts of the masses involved in a given reaction must not change in their proportions when the reaction is complete.
n other words, the mass prior to the chemical reaction and the mass following the reaction are equal. Nuclear reactions are the exception to the norm, where it is possible to change mass into energy and vice versa.

What is the bond between phosphorus and chlorine?
Phosphorus and chlorine form bond is covalent bond.
A covalent bond is likely to form if the difference in electronegativity between the elements is less than 1.7.
For instance, the electronegativity of phosphorus (P) is 2.1 and that of chlorine (Cl) is 3.0.
These two numbers are differentiated by 0.9. Since 0.9 is lesser than 1.7, phosphorus and chlorine form a covalent bond.
Chlorine and phosphorus are both found on the right side of the periodic table, which is where nonmetals are. As a result, a covalent bond will be formed between the two nonmetals.
So, we can say that covalent bond is between phosphorus and chlorine.

What are cinder cone volcanoes made up of?
Cinder cones are made up of layers of pebble-sized or larger cinders and layers of ash. Larger volcanic bombs and blocks may also be present.
cinder cone, also called ash cone, deposit around a volcanic vent, formed by pyroclastic rock fragments (formed by volcanic or igneous action), or cinders, which accumulate and gradually build a conical hill with a bowl-shaped crater at the top. Cinder cones develop from explosive eruptions of mafic (heavy, dark ferromagnesian) and intermediate lavas and are often found along the flanks of shield volcanoes. The outside of the cone is often inclined at about 30°, the angle of repose (the slope at which the loose cinder can stand in equilibrium). Cinder cones may be only a few tens of feet high, or they may grow to a height of several hundred meters (several thousand feet), like that of Paricutín in Mexico. Lava flows may break out of or breach the cone, or they may flow from under the cone through tunnels. Cinder cones are numerous in nearly all volcanic districts. Although they are composed of loose or only moderately consolidated cinder, many of them are surprisingly enduring features of the landscape because rain falling on them sinks into the highly permeable cinder instead of running off down their slopes to erode them.

what are neutral atoms on the periodic table
Neutral atom generally means to atoms which don't react with any other atoms or elements.
If an atom has an equal number of electrons and protons, then it also has an equal number of negative (the electrons) and positive electric charges (the protons). As a result, the total electric charge of the atom is zero, and the atom is said to be neutral. Thus, all the elements in the periodic table are neutral atoms.
Example of neutral atom
For example a neutral sodium atom which contains 11 protons and 11 electrons. And after removing an electron from this atom we get a positively charged Na⁺ ion that has a net charge of +1. Atoms become negatively charged when it gains extra electrons.

mL.
Considering the Boyle's law, the volume of the gas sample will be 997.908 mL.
Boyle's lawBoyle's law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant: if the pressure increases, the volume decreases while if the pressure decreases, the volume increases.
Mathematically, this law expresses that if the amount of gas and the temperature remain constant, the product of the pressure by the volume always has the same value:
P×V= k
where P is the pressure, V is the volume, and k is a constant.
Analyzing an initial state 1 and a final state 2, it is fulfilled:
P₁×V₁= P₂×V₂
New volume in this caseIn this case, you know:
P₁= 1.10 atm
V₁= 694 mL
P₂= 0.765 atm
V₂= ?
Replacing in Boyle's law:
1.10 atm× 694 mL= 0.765 atm×V₂

Is CO2 polar or nonpolar covalent bond?
Due to its symmetry and the fact that the pull of the two oxygen atoms on the electrons of carbon cancel each other out, carbon dioxide is a nonpolar molecule with polar bonds. Because the vector sum of the dipole moments of the two CO bonds is zero, the CO2 molecule is non-polar even if the CO bond in it is polar.
With carbon, each oxygen atom forms a double bond. Different electronegativities of carbon (C) and oxygen (O) result in unequal distribution of electrons between them. Due to the cancellation of the two bond dipole moments, there is no net molecule dipole moment. Carbon dioxide is a non-polar gas as a result.
