A cylinder containing 5.20 L of NO gas at 1.20 atm and 32 o C is compressed under 6.00 atm pressure to a volume of 2.08 L. What is the final temperature of the gas?

Answer:

Explanation:

Since electrons are particles that are in constant movement in a wave-like motion, is impossible to know exactly their position and velocity at all times. That's why instead of defining an orbit for them we define an atomic orbital, which is a location in space where the probability of finding an electron is high (therefore, is an electron dense zone). Since this zone has not defined limits (the wave function characterizing the orbital extend from the nucleus to infinity), the further we go from the nucleus the less dense this "cloud" is.

There is about a 90 percent probability of finding the electron  within a sphere of radius 100 pm surrounding the nucleus.  Thus, we can represent the 1 s orbital by drawing a boundary surface diagram that  encloses about 90 percent of the total electron density in an orbital, and the shape of this orbital is a sphere.

The boundary surface diagrams of p orbitals, for example, will have the shape of two lobes on opposite sides of the nucleus, that means that within this two lobes we have a 90 percent probability of finding the electron, and so on.

Answer:

B.) a cation that is smaller than the original atom

Explanation:

When the atoms of an element gains or loses electrons, it becomes charged. This charged atom is called an ION. An ion can either be a CATION or ANION depending on whether the atom loses electrons to become positively charged (cation) or gains electrons to become negatively charged (anion).

In this case, magnesium (Mg) atom gives up or loses electron(s) to become an ion, it will become positively charged and hence called a CATION. However, since it loses electrons in its atom, it becomes SMALLER than the original magnesium atom. This is because the electrons left in the atom becomes more attracted to the nucleus and decreases the ionic radius.

Answer:

Lavoisier disproved the phlogiston theory. He demonstrated that there was an element called oxygen that played a major role in combustion. He also showed that the mass of products in a reaction are equal to the mass of the reactants. The phlogiston theory did not account for the weight changes found in fire. Lavoisier hypothesized that it was probably the fixation and release of air, rather than fire, that caused the observed gains and losses in weight.

Answer:

put 5 dots

Explanation:

it has 5 valence electrons

Answer:

5

Explanation:

Antimony is in group 15 of the periodic table which means it has 5 valence electrons. Therefore, its Lewis Diagram should contain 5 dots to represent these 5 valence electrons.

Covalent bond

The mutual sharing of electron between 2 atoms is known as covelent bond

Standard pressure is equal to 1 atm. Therefore option 1 is correct.

Standard pressure is equal to 1 atm, which stands for atmosphere. It is a unit of pressure commonly used in the field of chemistry and physics. Standard pressure is defined as the pressure exerted by a column of mercury in a barometer when the atmospheric conditions are at standard temperature and pressure (STP).

STP is defined as a temperature of 0 degrees Celsius (273.15 Kelvin) and a pressure of 1 atmosphere (1 atm). Therefore, at STP, the standard pressure is equal to 1 atm.

While pressure can be measured in various units such as pascals (Pa), kilopascals (kPa), and atmospheres (atm), the standard pressure is specifically defined as 1 atm.

Explanation:

Frost forms when an outside surface cools past the dew point. The dew point is the point where the air gets so cold, the water vapor in the atmosphere turns into liquid. This liquid freezes. If it gets cold enough, little bits of ice, or frost, form

The coefficient for O₂ after balancing the equation is 4. The correct answer is A. 4.

To balance the equation C₄H₈ + O₂ → 4CO₂ + 4H₂O, we need to ensure that the number of each type of atom is the same on both sides of the equation.

Starting with carbon (C), we have 4 carbon atoms on the left side and only 1 on the right side (in CO₂). To balance carbon, we place a coefficient of 4 in front of CO₂:

C₄H₈ + O₂ → 4CO₂ + H₂O

Next, we move on to hydrogen (H). There are 8 hydrogen atoms on the left side, but only 2 on the right side (in H₂O). To balance hydrogen, we place a coefficient of 4 in front of H₂O:

C₄H₈ + O₂ → 4CO₂ + 4H₂O

Now, let's consider oxygen (O). On the left side, we have O₂, which contains 2 oxygen atoms. On the right side, there are 4 CO₂ molecules, each containing 2 oxygen atoms, and 4 H₂O molecules, each containing 1 oxygen atom. So, the total number of oxygen atoms on the right side is (4 x 2) + (4 x 1) = 8.

To balance oxygen, we need to have 8 oxygen atoms on the left side as well. Therefore, we place a coefficient of 4 in front of O₂:

C₄H₈ + 4O₂ → 4CO₂ + 4H₂O

Therefore, the coefficient for O₂ after balancing the equation is 4.

The correct answer is A. 4.

Answer:

Evaporation from the hydrosphere provides the medium for cloud and rain formation in the atmosphere. The atmosphere brings back rainwater to the hydrosphere. The atmosphere provides the geosphere with heat and energy needed for rock breakdown and erosion. The geosphere, in turn, reflects the sun's energy back into the atmosphere.

Answer: By performing the flame test

Explanation:

The flame test can be performed by the teacher to visually identify the substance in the solution. The metals give a characteristic color on burning. The heat of the flame causes the excitation of the electrons present in the metal ions this leads to release of energy along with the emission of visible wavelength of light. This visible light can be observed by human eye. For example, the copper produces the blue color in flame, barium gives green flame, and sodium gives yellow flame.
