Answer:
so like Each of the five states of matter collectively made up all the "stuff" that's in the universe- — everything that takes up space and has mass is matter,and All matter is made up of atoms and in turn made up of protons and neutrons and electrons.
Explanation: hope this helps
Indeed they are. The uranium atoms have separate numbers of neutrons in their nuclei, but still have the same number of protons.
Answer:
Turbines.
Explanation:
Hello,
In this case, we define steam as high-energy vapor water, which has the capacity to be cooled to release energy to a system. For instance, turbines, use overheated steam to produce energy, by feeding the steam to the turbine's rotor blades in order to make the rotate and generate work. As a consequence of the rotation, the steam loses energy, for which it goes out from the turbine at low both temperature a pressure, even do, in some cases it could go out liquid so a condensation may occur.
Regards.
Answer:
Mass = 51 g
Explanation:
Given data:
Mass of ammonia formed = ?
Number of moles of hydrogen = 4.50 mol
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
Now we will compare the moles of hydrogen and ammonia.
H₂ : NH₃
3 : 2
4.50 : 2/3×4.50 = 3 mol
Mass of ammonia formed:
Mass = number of moles × molar mass
Mass = 3 mol × 17 g/mol
Mass = 51 g
Answer:
B. The air pressure would increase 2X
Explanation:
Pressure = density × acceleration due to gravity × height
p = ρ × g × h
Pressure is force per unit area
p = F/a
Density is mass per unit volume
Pressure is directly proportional to density hence, any change in the density of a body directly affects the change in pressure of the body and vice versa.
