Cuando haces ejercicios abdominales estas realizando un trabajo. Si haces el mismo numero de abdominales en la mitad de tiempo que acostumbras, ¿como seria tu rendimiento en terminos de potencia comparandolo con el tiempo normal en que las haces?
Answer:
El rendimiento seria mayor ya que la potencia aumenta.
Explanation:
La potencia aumenta cuando determinado trabajo se realiza en menor cantidad de tiempo.

6. How many molecules are in 2.7 moles of carbon dioxide
Answer:
2.7×6.022×10^23
=16.594×10^23 moleclules
Explanation:
number of mol= 2.7
1 mol of any element=6.022×10^23
therefote 2.7 mol =2.7×6.022×10^23
=16.594×10^23

Explanation:
How many particles are in 3.4 moles of HCl?
Answer:
The volume is 77 L.
Explanation:
where P is pressure, V is volume, n is moles, R is the gas constant, and T is temperature in Kelvins.
The current STP temperature is 0∘C or 273.15 K (used for gas laws), and the pressure is 105Pa, which most people write as 100 kPa (both pressures are equal).
Which has more mass, one mole of carbon (C) or one mole of copper (Cu)?
Explain.
What volume of a 3.00M KL stock solution would you use to make 0.300 L of a 1.25M Kl solution?
Answer:
0.125L or 125 mL
Explanation:
See the image for steps!0.125L of 3.00M KI stock solution is required to make 0.300 L of a 1.25M KI solution.
What is solution?A solution is a homogeneous mixture of one or more solutes dissolved in a solvent.
What is stock solution?A stock solution is a concentrated solution that will be diluted to a solution of lower concentration.
stock solution = diluted solution
What do you mean by dilution?Dilution is the process of decreasing the concentration of a stock solution by adding more solvent to the solution. The solvent added is the water. The more the solvent you add, the more dilute the solution is.The equation for dilution is M1V1=M2V2Where, M1 = concentration in molarity (moles/Litres) of the concentrated solution
V2 = volume of the concentrated solution,
M2 = concentration in molarity of the dilute solution
V2 = volume of the dilute solution.
The volume of 3.00M KI solution can be calculated using the dilution equation:
Given:
M1 = 3.00M, M2 = 1.25M, V1 = x, V2 = 0.300L
M1V1 = M2V2
3.00M(x) = 1.25M(0.300L)
x = 0.125L
Hence, 0.125L of 3.00M KI stock solution is required to make 0.300 L of a 1.25M KI solution.

what is the most important part of an Atom? Why?
Answer:
I would say proton and electron are the two most important subatomic particles in an atom
Explanation:
The number of protons inside a nucleus must equal to the number of electrons outside of the nucleus. This number determines all the chemical properties of the atom, which governs the behaviors of all matters in our world.
