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!

<h3>
Answer:</h3>
79.8 ml
<h3>
Explanation:</h3>
Boyle's law describes the relationship between pressure and volume when the temperature is constant. For this question, I will be rounding to significant figures.
Boyle's Formula
When describing the relationship between pressure and volume, the formula
. In this formula,
is the initial pressure and volume. On the other side,
is final pressure and volume. So, to find a missing variable you must plug in the values you are given.
Final Volume
Remember when solving this question to remain constant in your units. When we plug in the values we know we are given:
Now, we can multiply the left side
Finally, we can divide by 385 to isolate the final volume
This gives the final volume of 79.8mL.
Answer:
You take the mass of carbon dioxide, 56.8g, divide by its molar mass, 44.01g/mol, to produce the moles of carbon dioxide. This is multiplied by the molar ratio of butane/CO2, (2/8) = 1/4, which gives the moles of butane required to produce the carbon dioxide.

Answer:
B
Explanation:
solute is what gets dissolved in the solvent
ie: salt in water. salt is the salute and the more of it you add to the water (solvent) the more interactions will occur increasing rate
The minimum energy required to remove an electron from a potassium metal can be obtained by subtracting the energy of the incident photons from the kinetic energy of the removed photoelectrons. Based from the given values, the following equation is obtained:
Minimum energy required = 4.23×10^-19 J - <span>1.864×10^-21 J
</span>
We then get 4.2114 x 10^-19 J as the minimum energy required to remove the electron. We then convert this into units of energy per mole. This is to be done by using Avogadro's number which result to the following equation:
Minimum energy required per mole = 4.2114 x 10^-19 J x 6.022 x 10^23 mol^-1
The final answer is then 253.608 kJ/mol
