Explanation:
Animals have to eat other living things to get their food, but plants can produce their own food. Plants absorb sunlight and use that energy to make glucose from carbon dioxide and water during the process of photosynthesis; glucose is the food plants can use as a source of energy or matter for growth
Answer:
Z=26, A = 56, charge +3.
Explanation:
The atomic number is represented by Z. Is equal to the total number of protons that the atom has. Z=26.
The atomic mass is represented by A. The number results from the total sum of protons and neutrons of an atom. Both particles have a weight of 1 uma, are in the nucleus and give the mass to the atom.
Mass number (A) = atomic number (Z) + number of neutrons (N)
A = 26 + 30
A = 56
The net charge of the atom can be calculated by subtracting the negative charges from the positive ones. The positive charges come from the protons and the negative ones from the electrons.
26-23=3
This iron ion has a positive charge +3.
Answer:
At equilibrium:
[H2] = 0.005 M
[Br2] = 0.105 M
[HBr] = 0.189 M
Explanation:
H2(g) + Br2(g) ⇄ 2HBr
an "x" value will be used from reactant to produced "2x"
so at equilibrium:
[H2] = 0.1 - x
[Br2] = 0.2 - x
[HBr] = 2x
we know that Kc=[HBr]²/[H2][Br2]
Thus 62.5 = (2x)²/(0.1-x)(0.2-x)
this generate a quadratic equation: 58.5x² - 18.75x + 1.25 = 0
the x₁ = 0.23 x₂ = 0.09457
we pick 0.09457 because the two reactants can not make more than what they have. x₁ is higher than both initial reactant concentration
Then we substitute the "x₂" value at equilibrium:
[H2] = 0.1-0.09457 = 0.005 M
[Br2] = 0.2-0.09457 = 0.105 M
[HBr] = 2*0.09457 = 0.189 M
Answer:
diamonds are carbon based and have a giant covalent structure
Explanation:
This is what gives diamonds its strength and rigidity.
Diamonds are different from graphite due to the way the atoms are arranged
The same sample of gas at different temperatures shows that at low
temperatures, most molecules have speeds close to their average
speed.

What does the Maxwell-Boltzmann distribution graph show?</h3>
Put simply, a Maxwell-Boltzmann distribution graph shows how the energy of gas particles varies within a system.
This is solely a measurement of the speeds of particles because kinetic energy is directly related to speed.
The Maxwell-Boltzmann distribution in chemistry is the subject of this article.
We will begin by describing how to read a graph of the Maxwell-Boltzmann distribution. This will involve taking a closer look at things like the typical energy and the most likely energy.
The graph will then be changed under various circumstances, such as when a catalyst is added or the temperature is raised.
The Maxwell-Boltzmann distribution, which we previously mentioned, is a probability function that depicts the distribution of energy among the particles of an ideal gas. (For more information on this topic, see Chemical Kinetics.)
