B) hydrogen peroxide.
C) sulfuric acid.
D) methane.
Burning fossil fuels in a low oxygen environment most likely produces carbon monoxide due to incomplete combustion. This is because there isn't enough oxygen to react with carbon, leading to formation of carbon monoxide instead of carbon dioxide. The correct option is A.
When fossil fuels are burned in a low-oxygen environment, the most likely product will be carbon monoxide (A). This occurs because in a low-oxygen environment, there is not enough oxygen to react with the carbon atoms in the fossil fuels to form carbon dioxide, which is the normal product of combustion in a high-oxygen environment. Instead, each carbon atom reacts with only one oxygen atom, forming carbon monoxide instead of carbon dioxide. It's also important to note that the production of carbon monoxide in such situations is a significant health hazard as it is a poisonous gas.

Explanation:
Via Educere/ Founder's Education
B) It has increased slightly
Answer: Helium is least likely to form bonds.
Explanation:
Helium has the electronic configuration . As the 1s sub-shell is completely filled so there is no need for helium to form bonds with other atoms.
Whereas, nitrogen has the electronic configuration . As the p sub-shell is half filled, it has the tendency to accept more electrons. Therefore, nitrogen is more susceptible to form bonds as compared to helium.
Thus, it is concluded that helium is least likely to form bonds.
Light of certain energy shines on a metal and causes electrons to be emitted. Based on the research of Albert Einstein, the change that would most likely result in stopping the emission of electrons from this metal is to coat the metal.
your answer is: the use of that light has a lower frequency
reactivity
valence electrons
atomic radii
atomic mass
Explanation:
When we move down a group then there will be increase in number of shells present in an atom. Due to this there will be increase in atomic radii of the atom.
As a result, there will be increase in atomic mass of the atom also. Whereas reactivity of metals increases on moving down the group as the valence shell moves away from the nucleus. So, it becomes easy for the metal atom to lose an electron.
On the other hand, reactivity of non-metals decreases on moving down the group.
So, we can conclude that properties increase when moving down a group of the periodic table are atomic radii and atomic mass.
Atomic Mass.
Reactivity decreases as you go down a group.
Atomic Radius also decreases as you go down a group.
Valence electrons are the same within a group.
Atomic mass, however, increases as you go down a group.
Hope this helps!
