1. No, it doesn't.
2. 4 Hydrogen atoms are on the reactants side and 2 hydrogen atoms on products side.
3. Because the mass of reactants is not equal to the mass of the products thus it doesn't follow the law of conservation of matter.
But on balancing the eqn,
CH4 + 2O2 > CO2 + 2H2O
The above eqn will follow the law of conservation of matter because the mass of reactants is equal to the mass of products.
the kinetic theory of matter explores the spatial relationship between the particles of solids liquids and gases , which of the following processes causes the distance between particles to increase the most?
A-Melting
B-Freezing
C-Sublimation
D-condensation
Which choice is an element? carbon dioxide water carbon air
Answer:
carbon
Explanation:
Considering the definition of elements ans compounds, carbon is an element.
Elements are simple substances that cannot be broken down by common chemical methods. The atoms in an element are the same as each other, yet they are different from those in other elements. In addition, the elements are represented by a symbol and can be found in the periodic table.
On the other hand, compounds are substances that are the result of the chemical union of two or more elements. This combination makes it impossible to identify each element by its individual and original properties. Compounds can be separated by chemical action.
In summary, the element is a pure chemical substance formed from an atom, which is characterized in that it cannot be divided or transformed by a chemical reaction. Whereas a compound is a pure chemical substance made up of a particular set of molecules or ions that are chemically bound together.
So, being:
carbon dioxide: composed of carbon and oxygen water: composed of two atoms of hydrogen and one of oxygenair: composed mainly of oxygen and nitrogenthen, carbon is an element.

https://brainly.com/question/20716171?referrer=searchResultshttps://brainly.com/question/13654839?referrer=searchResultshow are the light reactions and the calvin cycle connected?
Answer:
The light reactions provide the Calvin cycle with oxygen for carbon fixation, and the Calvin cycle provides the light reactions with sugars to produce ATP. The light reactions provide ATP and NADPH to the carbon fixation step of the Calvin cycle, and the Calvin cycle provides water and electrons to the light reactions.
Explanation:
The energy that drives the Calvin cycle comes from ATP and NADPH produced by the light reactions, that is, the energy capture reactions in the first stage of photosynthesis.
The Calvin cycle is a process that results from photosynthesis made by plants, through which Carbon dioxide is absorbed and transformed into organic material or biomass.
In the light phase, light energy is stored in organic molecules that provide energy to carry out the process (ATP) and have the ability to donate electrons (reducing power) to another molecule such as NADPH.These molecules formed in the light reactions participate in the reactions that make up this cycle during which carbon dioxide (CO2) taken from the atmosphere is fixed, incorporating it into the body in the form of glucose thanks to the action of the enzyme RuBisCo.Therefore, we can conclude that the molecules constituted in the light reactions (ATP and NADPH) participate in the reduction of carbon dioxide (CO2) through the series of reactions of the Calvin Cycle.

Most lakes have rivers flowing out of them, carrying water to the ocean. However, some
lakes, including Great Salt Lake and the Dead Sea, have no outlet. Water flowing into
these lakes leaves only through evaporation. Considering that the water flowing into the
lakes contains many dissolved substances, how does the lack of an outlet affect the
composition of these lakes? What would you expect to happen after many more years
of inflow and evaporation?
Answer:
I feel like it could lead to flooding

how can you calculate the number of electrons present in a shell? pls help!!! will give brainliest
Answer:
The maximum number of electrons present in a particular shell is calculated by the formula 2n2, where “n” represents the shell number. For instance, K shell is the first shell and it can hold up to 2(1)2 = 2 electrons. Similarly, L shell is the second shell and it can hold up to 2(2).

Nitrogen has 5 electrons in its valence shell. How many more electrons will it likely gain? As a result, what charge will the Nitrogen in the above problem have?
Answer: 3 electrons; charge = -3
Explanation:
Nitrogen will likely gain 3 electrons.
Nitrogen will therefore carry a charge of -3. (since gaining electrons causes a negative charge.

31: 1366.82
32: 6.45062
33: 12.50400
34: 210.42700
35: 63.88200 cm
36: -970.8772
Explanation:
4.550 x 300.4 = 1366.82
2.45002 + 4.0006 = 6.45062
26.004 - 13.5 = 12.50400
2.667 + (5.6 x 37.1) = 210.42700
2.34 x 4.55 x 6.0 = 63.88200
4.60 x 5.16 x 1.05 + 6.2 - 1002 = -970.8772
What does temperature indirectly measure? 1)Sound 2)Thermometers 3)Chemical Reactions 4)Heat
Answer:
Heat
Explanation:
Temperature is the average thermal energy (or heat) in a substance. Sound isn't really related, thermometers measure temperature, and chemical reactions can produce heat, but none of those are measured by temperature.

what is the maximum wavelength of photon that will eject a ground state electron from a hydrogen atom?
Answer:
9.13 x 10^-8 m
Explanation:
The maximum wavelength of photon that will eject a ground state electron from a hydrogen atom is 9.18 * 10^-8.
What is wavelength?
Wavelength is defined as the distance between identical points in the adjacent cycle of a waveform signal propagated in space or along the wires.
Wavelength is calculated as wave speed and frequency.
Wavelength = speed/frequency
SI unit of wavelength is meter.
A ground state atom is an atom in which total energy of the electron can not be lowered by transferring one or more electrons to different orbitals.
Thus, the maximum wavelength of photon that will eject a ground state electron from a hydrogen atom is 9.18 * 10^-8.

a) What is the role of neutrons in an atom?
b) How do we determine how many neutrons are in an atom?
Answer:
numer 1:Neutrons are required for the stability of nuclei, with the exception of the single-proton hydrogen nucleus. Neutrons are produced copiously in nuclear fission and fusion. They are a primary contributor to the nucleosynthesis of chemical elements within stars through fission, fusion, and neutron capture processes.
number 2:The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).let me know if i helped
Write Cadmium nitride formula using criss cross method
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here calcium is having an oxidation state of +2 called as Ca^{2+}Ca2+ cation and NO_3^{-}NO3− is a polyatomic anion with oxidation state of -1.. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral Ca(NO_3)_2Ca(NO3)2
