A) Jupiter because it has the largest mass of all the planets
It will expand because the helium atoms will move more quickly and get farther apart. This is your answer because as the particles get more heated, they start to increase the kinetic energy and move more.
Renewable energy source
reduces electric bills
low maintenance costs
reduced needs for fossil fuels and foreign oils
Answer:
Nickel is extracted from nickel oxide by reduction with carbon. Nickel is a metal which react with atmospheric oxygen which is very reactive in order to protect the inner surface of metal. Carbon extract oxygen which is attached to the nickel in the form of nickel oxide because carbon is more reactive so it made a chemical bonds with oxygen and nickel oxide is converted into a pure nickel.
Answer:
Synthesis reaction
Explanation:
To know which option is correct, it important that we know what each option represents.
Synthesis reaction is a reaction in which two different elements react to form a single compound. For example
X + Y —> XY
Decomposition reaction is a reaction in which a compound splits into two or more simpler substance. For example
XY —> X + Y
Single Replacement reaction is a reaction in which one element replaces or displaces another element from a compound. For example
X + YZ —> XZ + Y
Double Replacement reaction is a reaction in which the parts of two ionic compounds exchange their ions to form a new compound. For example
WX + YZ —> WZ + YX
Now, considering the equation given above i.e
P + O₂ —> P₄O₁₀
We can see that P and O₂ reacted to produce a new compound (i.e P₄O₁₀).
Thus, the reaction is a synthesis reaction because two different elements (i.e P and O₂) reacted to form a single compound (i.e P₄O₁₀).
