The effects of long-term exposure to mustard gas causes mortality and chronic respiratory disease.

Exposure to mustard gas in the long term can result in mortality from influenza, pneumonia as well as chronic breathing disease. Exposure for long term leads to respiratory complications and septic shock. Extensive breathing in the environment of mustard gas can cause chronic respiratory disease, respiratory infections or death.

Extensive eye exposure to this gas can cause permanent blindness. Exposure to mustard gas may also increase the chances of lung and respiratory cancer so we can conclude that mustard gas is lethal and can cause a number of diseases in a person who is exposed to it.

A 3.00-L container with O₂ at 4.00 atm is connected to a 2.00-L container with Ne at 2.00 atm, resulting in a final pressure of 3.20 atm in the container.

We have 2 containers connected by a valve.

One container has a volume of 3.00 L and contains O₂ at 4.00 atm. The other container has a volume of 2.00 L and contains Ne at 2.00 atm.

When the valve is opened, the total volume is the sum of the 2 containers.

[tex]V_2 = 3.00 L + 2.00 L = 5.00 L[/tex]

Assuming constant temperature and ideal behavior, we can calculate the final pressure of each gas using Boyle's law.

O₂

[tex]P_1 \times V_1 = P_2 \times V_2\\\\P_2 = \frac{P_1 \times V_1}{V_2} = \frac{4.00atm \times 3.00L}{5.00L} = 2.40atm[/tex]

Ne

[tex]P_1 \times V_1 = P_2 \times V_2\\\\P_2 = \frac{P_1 \times V_1}{V_2} = \frac{2.00atm \times 2.00L}{5.00L} = 0.800atm[/tex]

The final pressure in the container will be the sum of the final pressures of the gases.

[tex]P = 2.40 atm + 0.800 atm = 3.20 atm[/tex]

A 3.00-L container with O₂ at 4.00 atm is connected to a 2.00-L container with Ne at 2.00 atm, resulting in a final pressure of 3.20 atm in the container.

Answer:

The nucleus of atom is composed of two subatomic particles that each have charges.

Both reside in the nucleus of an atom. The amount of protons and neutrons (Electrons can to) is what helps us identify each atom apart. Electrons are NOT in the nucleus of atom but orbit it in outer layers called orbitals.

Main compounds of milk are lactose and casein. And it is also called a colloidal mixture (i.e. in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance). Therefore milk is regarded as a mixture not as a pure substance. So this is the required answer.

Answer:

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.

₈₂Pb²⁰⁸ => ₈₀Hg²⁰⁴ + ₂He⁴ =>  ₈₀Hg²⁰⁴ + (₂α⁴)⁺²

Note the sum of superscripts & subscripts of reactants (₈₂Pb²⁰⁸) must equal sum of superscripts & subscripts of products (₈₀Hg²⁰⁴ + ₂He⁴); that is ...

∑mass reactants = ∑mass products => 208 = 204 + 4

Explanation:

How is the relatively high melting point of sodium chloride related to its structure at the atomic scale? Observe sodium chloride crystals with a hand lens. Use your observations and the model of sodium chloride to support your claim.

Unlike the raltively low melting point of water (100 °C), NaCl has a much higher melting point (801 °C),.

Theater molecules in ice are held together by hydrogen bonds, which are relatively weak.

The ions in NaCl are held together by  ionic bonds, whose electrostatic ,force is much greater.

The crystal structure makes the force even greater.

imagine a chloride ionin a NaCl crystal.

It has Na ions in front, behind, to the left, to the right, above and below.

Likewise the Na ion has Cl ions in front, behind, to the left, to the right, above and below.

It takes a lot of energy to berak these bonds and temprature is a measure of energy.

if you try the experiment make certain you are undr a fune hood and wear protective loves and apron.   801 °C can seriously burn skin and clothing

The temperature at which the liquid and the solid of refined compounds and elements can occur stable and in equilibrium is called the melting point.

Therefore, the melting point is related to the structural organization of the atoms.

Explanation:

Explanation:

When dilute HCl is added to a small amount of copper oxide in a beaker, a greenish-yellow gas is released and a bluish-green solution is formed. Since the metal oxides such as a Copper oxide (CuO) are basic in nature, it reacts with acids such as HCl to form the corresponding salt and water.

Answer:

It's because the solubility of gases in water is inversely proportional to the temperature, so it means when the temperature is increased, the solubility decreases, and the gases tend to get out from the soda

Answer:

A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.
