What are the components needed in order for an experiment to be valid? Identify these components in the following experiment: A
VMariaS [17]
He is missing a (real) control. Growing two plants without plant food at all doesn't count; in order to see if the new food is better, he must also grow plants with the original food in order to compare it. 

He does have an independent variable. This is the type of plant food. It's independent because he has direct control over it.

He needs to give plants the same conditions besides food: same water (amount), same light exposure, same temperature, etc.

He needs to choose a quantitative way to measure how much the plants grew, like mass or length.

an ideal gas is at a pressure 1.00 x 10^5 N/m^2 and occupies a volume 11.00 m^3. If the gass is compressed to a volume of 1.00 m
bogdanovich [222]

Answer:

P_2=1.1x10^6Pa

Explanation:

Hello.

In this case, we can solve this problem by applying the Boyle's law which allows us to understand the pressure-volume behavior as a directly proportional relationship:

P_1V_1=P_2V_2

In such away, knowing the both the initial pressure and volume and the final volume, we can compute the final pressure as shown below:

P_2=\frac{P_1V_1}{V_2}

Consider that the given initial pressure is also equal to Pa:

P_2=\frac{1.00x10^5Pa*11.00m^3}{1.00m^3}\\ \\P_2=1.1x10^6Pa

Which stands for a pressure increase when volume decreases.

Regards.

Why is it easier to remove an electron from a sodium atom than a magnesium atom
gulaghasi [49]
It doesn't take much energy to remove one electron from a sodium atom to form an Na+ ion with a filled-shell electron configuration. The first ionization energy of magnesium is larger than sodium because magnesium has one more proton in its nucleus to hold on to the electrons in the 3s orbital.
