Answer:
The carbons on either side of the double bond are pointed in the same direction
Answer:
28
Explanation:
28 is correct. (NH4)2 is equal to 10 atoms. (8 H and 2 N ) CO3 is equal to 4 atoms. (1 C and 3 O) That's 14 atoms. But it's two molecules of this. So you just multiply by the number of molecules (2), and you get 28.
Answer:
The unfiltered polluted water is not clear and is yellowish in color. The filtered polluted water is clear with a little bit of yellow color. The pH readings are beyond the range in which organisms can grow. Based on these observations, I can conclude that even though water may look clean, it could actually not be clean or it can still be harmful to living things.
Answer:
Electrons in the outermost energy level of an atom are called VALENCE ELECTRONS.
Answer:
3
Explanation:
There are three different elements in given chemical equation. These elements are hydrogen, oxygen and carbon.
Chemical equation:
2CH₄ + 4O₂ → 2CO₂ + 4H₂O
This equation shows the burning of methane. When methane burns in the presence of oxygen it produced water and carbondioxide.
We can see that all the reactant and product are made up of only three elements carbon, hydrogen and oxygen.
There are two reactant and two products in given reaction.
This reaction also follow the law of conservation of mass.
We can see that there are two carbon eight hydrogen and eight oxygen atoms on both side of equation.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
