Answer:
Nitrogen dioxide is a compound made of two nonmetals.
Explanation:
Nitrogen dioxide is made by 1 nitrogen atom and two oxygen atoms. Nitrogen and oxygen are both gases. That being close to being metalloids they aren't because they can't change their structure as metalloids do. Their covalent bonds are also weaker to be considered metalloids.
the answer is
two nonmetals
i just did this and got this answer
A) Ca
B) Se
C) Zn
D) Mn
Answer: non metal
Explanation:
Nonmetals are dull, possess high ionization energies and electronegatives and are typically poor electricity conductors as they're insulators.
Non metals are also brittle and possess low melting point. Therefore, with the explanation, the sample is most likely a non metal.
The sample described is most likely a sulfur solid.
The sample described in the question, which is pale yellow, brittle, and has no shine, is most likely a sulfur solid. Sulfur is a chemical element that is commonly found in its solid form and has a pale yellow color. It is brittle, meaning that it shatters easily upon impact, and it does not have the characteristic shine that metals have.

What is the equilibrium concentration of N2O4 if the equilibrium concentration of NO2 is 0.785 M?
The balanced chemical reaction will be:
C3H8 + 5O2 = 3CO2 +4H2O
We are given the amount of oxygen gas to burn the propane gas. This will be our starting point.
34.0 L O2 ( 1 mol O2 / 22.4 L O2 ) (1 mol C3H8 / 5 mol O2 ) ( 22.4 L C3H8 / 1 mol C3H8) = 6.8 L C3H8
The most abundant element in the earth core is oxygen the most essential and precious gas. Second most abundant element is silicon.
Elements are the basic things in the universe. Everything in the world is made of elements. Elements combines to form molecules, molecules then forms compounds and compounds makes the macrothings.
There are various kinds of elements such as metals, gases, metalloids. etc. These all elements shows their characteristic physical and chemicals behaviours. Based on their electronic properties all the elements are classified into various groups in periodic table.
Oxygen is the most abundant element in the earth core that we all are used to intake for respiration. Oxygen s 8th element in periodic table and it is in P-block.
Silicon is the second most abundant element in the earth core. Silicon is a metalloids in 14th group of p-block and it is 14th element in periodic table. It is used in many electronic devises.
