Compounds of carbon and hydrogen
Explanation;
An organic compound is any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.
The primary difference between organic compounds and inorganic compounds is that organic compounds always contain carbon while most inorganic compounds do not contain carbon. Additionally, nearly all organic compounds contain carbon-hydrogen or C-H bonds.
Organic compounds includes nucleic acids, fats, sugars, proteins, enzymes and hydrocarbon fuels. All organic molecules contain carbon, nearly all contain hydrogen, and many also contain oxygen.

Which of the following shows the combustion of a hydrocarbon?A. 2C2H2 +502 + 4CO2 + 2H20O B. CO2 + H2O → H2CO3O C. NaOH + HCl → NaCl + H20O D. C2H4 + Cl2 → C2H4Cl2
Which of the following statements best explains why the atomic radius increases from top to bottom of the periodic table? A. The electronegativity decreases from top to bottom of the periodic table, so the atoms near the bottom have an increased capacity for electrons. B. For the atoms lower in the periodic table, there is more difference in charge between the electrons and the protons, which allows electrons to orbit farther from nucleus. C. The ionization energy decreases from top to bottom of the periodic table, so the atoms near the bottom have an increased capacity for electrons. D. For the atoms lower in the periodic table, the valence electrons are in higher energy levels and farther from the nucleus.

Answer:
so the reaction rate increases by a factor 6.
Explanation:
For the given equation the reaction is first order with respect to both ester and sodium hydroxide
So we can say that the rate law is
now as per given conditions the concentration of ester is increased by half it means that the new concentration is 1.5 times of old concentration
The concentration of NaOH is quadrupled means the new concentration is 4 times of old concentration.
The new rate law is
the final rate = 6 X initial rate
so the reaction rate increases by a factor 6.

Answer:
The glass cup falling from the counter
Explanation:
the glass isn't changing in any chemical way. it's still made of the same material, just broken apart.
Final answer:
Physical changes involve the alteration of the state or appearance of matter, without changing the composition. An example is solid wax turning into liquid wax when heated, or steam condensing inside a cooking pot.
Explanation:
The question asks for an example of a physical change. Physical changes involve alterations in the state or appearance of matter, without changing its composition. For example, solid wax turning into liquid wax when heated is a physical change. The wax is still the same substance, it's just in a different state. Similarly, steam condensing inside a cooking pot is also a physical change. The water vapor turns back into liquid water, but it's still water. These are distinguished from chemical changes, which transform one substance into a different substance.

Answer:
A. 1 J=1kg•m^2/s^2
Explanation:
Energy refers to the capacity to do work. According to the International System of units (SI units), energy is measured in Joules.
Energy is represented by the force applied over a distance. Force is measured in Newton (N) and distance in metres (m). Hence, energy is Newton × metre (N.m)
Newton is derived from the SI units of mass (Kilograms), and acceleration (metres per seconds^2) i.e Kg.m/s^2, since Force = mass × acceleration.
Since; Energy = Newton × metres
If Newton = Kg.m/s^2 and metres = m
Energy (J) will therefore be; Kg.m/s^2 × m
1J = Kg.m^2/s^2

Answer:
Ionization
Explanation:
Molecular compounds are chemical compounds composed of discrete molecules. A molecular compound undergoes ionization when being dissolved in water and the formation of ions are being produced. For example, hydrogen chloride is a molecular compound, when it dissolves in water, ionization is being carried out, and ions are being formed.
