Answer:
2Fe + 3H2SO4 → Fe2(SO4)3 + 3H2
Explanation:
Iron is a metallic element with chemical symbol, Fe while concentrated sulphuric acid is a chemical compound with chemical formula, H2SO4. Both are involved in a chemical reaction as follows:
Fe + H2SO4 → Fe2(SO4)3 + H2
However, this reaction is not balanced as the number of moles of each atom in both the reactants and product side is not equal. To balance the equation, we have to ensure that each number of atom is equal. The balanced equation are as follows:
2Fe + 3H2SO4 → Fe2(SO4)3 + 3H2
When a man travels from earth to space, the mass of the person, defined as the amount energy a matter has remains constant. However, when he moves to space, gravity decreases until such time that there is no gravity that acts on the person. Weight thus changes or decreases until the point of state called weightlessness.
Answer:
Because of the tilt of Earth on its axis, Earth's surface and atmosphere are unevenly heated by the Sun. Convection currents form in the atmosphere as warmer air rises and cooler air sinks.
