A teacher wrote the following part of a chemical equation: 2H2 +02 - ?
What compound is most likely produced by the chemical reaction
represented by this equation?
A.2CO2
B.2012
C.2HCI
D.2H2O

2H₂+O₂⇒ 2H₂O

Given

Chemical equation :

2H₂+O₂⇒

Required

Compound produced

Solution

In determining the product that may be produced is to use the principle of the law of conservation of mass where the number of atoms/elements in the reaction either before the reaction (reactants) or after the reaction (products) is the same so that a balanced chemical equation is formed.

In the above reaction, there are two elements that play a role in the reaction, namely H and O

So that the resulting product also has these 2 elements, so we can ignore options A and C because there are elements C and Cl, while choice B does not contain the element H

The right choice: D

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

1.solid

2.carbon dioxide

3.helium
