Answer: Gravity
Explanation: The answer is gravity: an invisible force that pulls objects toward each other. ... So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body.
The general formula for alkyne series is CnH2n-2
This is because alkyne is unsaturated hydrocarbon which has one triple bond and has no functional group from homologous series. Alkyne has a general formula of CnH2n-2
An example of an alkyne in ethyne with HC≡CH chemical formula ,
another example is propyne with CH3C≡CH formula
Answer: The destruction of crust occurs at deep-sea trenches. Oceanic rocks are pillow-shaped when formed. Rocks across the ocean floor have alternating magnetic stripes. Younger rocks are closer to mid-ocean ridges.
Explanation:
a) H2S (aq) + 2 O2 (g) → H2SO4(aq)
b) H2SO4 (aq) + CaCO3(s) → CaSO4 (s) + H2O (L) +CO2 (g)
To identify a redox reaction, we have to monitor the oxidation number of the elements to see if there is change.
In reaction (a);
The oxidation number of S increases from -2 (H2S) to + 6 (H2SO4). Also the oxidation number of O decreases from 0 (O2) to -2 (H2SO4). This is a redox reaction.
The oxidizing agent is O2 because it was reduced and the reducing agest is H2S.
In reaction (b);
There is no change in oxidation number in any f the elements. This is not a redox reaction.
