The volume of water that should be added in the given solution is equal to 202 ml.

The concentration or the volume of the dilute or concentrated solution can be calculated from the following equation:

M₁V₁ = M₂V₂

where M₁, V₁, M₂, and V₂ are the concentration and volume of the concentrated solution and dilute solution respectively.

Given, the concentration of the solution, M₁ = 0.14 M

The concentration of the diluted solution, M₂ = 0.100 M

The volume of concentrated solution, V₁ = 505 ml

Put the value of the molarity and volume in equation (1):

(0.140)× (505) = (0.100) × (V₂)

V₂ = 707 ml

The amount of water should be added = 707 - 505 = 202 ml

According to the research, the correct answer is solidification and condensation. These processes that decrease the motion of particles.

Solidification refers to the state that can be produced by the compression of the matter in question or by a drop in temperature, decreasing the kinetic energy of the particles, favoring the appearance of cohesive forces between them.

In this sense, condensation is the process of transforming a gaseous body into a liquid, by decreasing the temperature, decreasing the energy contained in the gas particles, therefore their motion.

Therefore, we can conclude that solidification and condensation are processes that imply a decrease in temperature and therefore decreases the motion of particles by losing energy.

Based on the mole ratio of the balanced equation of the reaction,

The mole ratio of the reaction is obtained from the balanced equation of the reaction as follows:

Balanced equation of reaction: 2 C₂H₆ + 7 O₂ ------> 4 CO₂ + 6 H₂O

From the balanced equation of the reaction, the mole ratio of the reaction shows that 2 moles of ethane, C₂H₆, undergo combustion with 7 moles of oxygen, O₂, to produce 4 moles of carbon (iv) oxide, CO₂, and 6 moles of water, H₂O.

Hence;

4.5 moles of ethane will require 4.5 * 7/2 moles of oxygen

moles of oxygen required = 15.75 moles of oxygen

Moles of carbon (iv) oxide, CO₂, produced = 4.5 * 4/2

Moles of carbon (iv) oxide, CO₂, produced = 9 moles

Moles of water, H₂O, produced = 4.5 * 6/2

Moles of water, H₂O, produced = 13.5 moles

Answer: copper is a fcc.

Explanation:

Solid copper can be described as the arrangement of copper atoms in a face-centered-cubic (fcc) configuration.

Solid copper can be described as the arrangement of copper atoms in a face-centered-cubic (fcc) configuration.

Two of the most recognizable crystal shapes are face-centered cubics (FCC) and body-centered cubics (BCC). There are FCC, BCC, or HCP structures for almost all elements.

The atomic configurations are where FCC and BCC crystals diverge most drastically. All 8 corner positions and the centers of each of the six faces are occupied by atoms in the face-centered cubic structure. All eight corner positions and the cube's center are occupied by atoms in the body-centered cubic structure.

Compared to BCC metals, FCC metals are often more ductile, more stable at high temperatures, and more dense. This is a result of their packaging design and slip systems.

The most effective atomic configuration is found in FCC (tied with HCP).

Because of this, we refer to FCC as a "close-packed" structure. FCC metals will typically be more dense and stable because FCC atoms are grouped more tightly together than BCC atoms.

Answer: a

Explanation:

Answer:

Both can be measured with a low level of certainty at the same time.  

it depends on what you count as low or high levels of uncertainty though.

Explanation:

The equation is something like:
[tex]\Delta x \Delta p \geq \frac{h}{4 \pi}[/tex]

delta x is the uncertainty (not change) of position, and delta p is the uncertainty of momentum. then term on the right is a constant (in this case, a very small number)

This equation tells us that neither the uncertainty of position nor the uncertainty of momentum can be zero, which means that there will always be some uncertainty. However, we can note that both of the uncertainties can be quite small at the same time, they just can't be smaller than h/4pi. This means that both can be measured with a fairly high level of certainty at the same time. However, there is a limit of how high the values can be, so i would expect that the answer your teacher is looking for is that both can be measured with a low level of certainty at the same time. This is always true, as opposed to saying that both can be measured when a high level of certainty at the same time, since high is quite subjective
