Then you have to balance each half reaction first with electrons before adding them together in one equation

⇒

and

⇒
and then combine them together to form

⇒

It isn't necessary to keep the electrons but its essential to know how many there are in order to know how many are in the equation in order to calculate the reaction energy. Note: A<span>dd H+ and H2O to balance the H's and O's in acidic solution if needed.</span>
Space Manned Exploration, more commonly known as Human spaceflight, is a type of space travel that launches to space with a spacecraft, including crews or regular passengers. The very first launching program that NASA made was back in 1958 was the Project Mercury with the goal for the first human put into Earth's orbit to survive and come back safely. Other famous spaceflights include the 1969's first moon landing of <span>Neil Armstrong and Edwin "Buzz" Aldrin. Today, NASA has confirmed another attempt to make a spaceflight to the moon in 2020 or 2023. We aren't far from those dates, so let's see what they can do!
