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!

In the very beginning of the era of space exploration each new discovery definitely weighed a lot. The humanity has learnt many new amazing things and it is natural that we want to know more and more. However, do we have enough technology and intelligence for it?

Sian Meaney, a journalist and researcher at Cherwell College in Oxford, the UK, writes that such giants as China and Russia have recently made no claims to the scientific benefits of manned missions. Nevertheless, space exploration takes the money that could be spent on the development of “earthly” sciences, or on the exploration of the planet Earth itself.

The supporters of manned space missions argue that it is so natural for the human to explore new territories and acquire new knowledge. But don’t the secrets of our planet suffice to satisfy scientists’ interest? Can’t complex human body and soul be the main subjects of heavily invested studies? We still do not know the entire truth about our world. So, how dare we intrude on the one where our laws do not work?

John and Alex were asked to make a 0.70 M solution. John measure out .35 L from the 2.0 M solution before asking how much soluti
nasty-shy [4]

Answer:

1.0 L

Explanation:

Given data

  • Initial volume (V₁): 0.35 L
  • Initial concentration (C₁): 2.0 M
  • Final volume (V₂): ?
  • Final concentration (C₂): 0.70 M

John and Alex prepared a diluted solution from a concentrated one. We can find the volume of the diluted solution using the dilution rule.

C₁ × V₁ = C₂ × V₂

V₂ = C₁ × V₁ / C₂

V₂ = 2.0 M × 0.35 L / 0.70 M

V₂ = 1.0 L
