What is the percent of hydrogen in C12H22011

Answer:

The reason is that there are radioactive elements that are in the center of the earth.

Explanation:

If the earth were only a rock cooling from the time of its birth. It should have already cooled completely thousands of years ago. However, volcanoes continue to shed hot magma and this is proof that there is a source of heat in the center of the earth. This source of heat is due to the radioactivity of elements such as Uranium and Thorium that were enclosed during the formation of the earth. These elements slowly disintegrate emitting particles that collide with others emanating heat.  For example, the half-life of uranium is 4.5 billion years, which means that it decays very slowly.

FE stands for iron in the Periodic Table of Elements.

Iron is a chemical element with the atomic number 26 and the symbol Fe, derived from the Latin word "ferrum." It is a transition metal and belongs to Group 8 and Period 4 of the periodic table.

Iron is well-known for its distinctive qualities, including its tremendous strength, silvery-gray colour, and magnetic tendency. It is an essential component in the creation of steel and is necessary for many biological activities, including the transfer of oxygen in the blood. Iron compounds are frequently employed in both industrial settings and daily life.

Answer:

CuO(s) + H₂(g) →  Cu(s) + H₂O(l)

Explanation:

• Assuming the reaction is the reduction of CuO by H₂
• Then the balanced equation for the reaction is;

CuO(s) + H₂(g) →  Cu(s) + H₂O(l)

• The equation shows the reducing property of hydrogen gas, such that hydrogen reduces metal oxides such as copper(ii)oxide to the respective metals.
• The law of conservation requires chemical equations to be balanced so as the mass of reactants will be equal to that of products.

• In this case; there is 1 copper atom, 1 oxygen atom and 2 hydrogen atoms on both side of the equation and thus the equation is balanced.
