Explanation:
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.
balance CHCl3 + O2 = CO2 + H2O + Cl2
Answer:
2CHCl3 + 5/2 O2 => 2CO2 + H20 + 3Cl2
Explanation:
Left Hand Side(LHS)
We have CHCl3 and O2
Right Hand Side(RHS)
We have CO2, H2O and Cl2
Balancing
To make sure that they have same values, put 2 before CHCl3 giving 2CHCl3 and 3 on Cl2(RHS) for chlorine gas giving 3Cl2
H2O remains the same
Before CO2 put 2 giving 2CO2
To make sure that oxygen is balanced put 5/2 before it. This gives 5/2 O2 (2 cancels out don't worry)
Combining all;
2CHCl3 + 5/2 O2 => 2CO2 + H20 + 3Cl2
I hope this helps. Have a nice studies.
Which of the following correctly completes the statement?
Cations are always _____ than the parent atom and anions are always _____ than the parent atom.
Answer: smaller, larger
Explanation:
Cations are always {smaller} than the parent atom. Anions are always {larger} than the parent atom.
Cations are always smaller than the parent atom, and anions are always greater than the parent atom.
What is parent atom ?The term "parent atom" refers to an atom that has not yet undergone any chemical transformation. A parent atom is one that is discovered in its initial state.
Because they contain fewer electrons while maintaining the same nuclear charge, cations are always smaller than their parent atoms. Because the protons in the nucleus are holding the remaining electrons more tightly, their radii are less than those of the parent atoms. In the case of anion, this is the opposite.
Due to variations in electron-electron repulsion, the ionic radii of cations and anions are always less or bigger than the parent atom, respectively. The trends in ionic radius follow those in atomic size.
Thus, Cations are always smaller than the parent atom, and anions are always greater than the parent atom.

wht will react with acid to giv bluish green salt nd water ??
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.
Based on their definitions, electron affinity could be considered the opposite of
Based on their definitions, electron affinity could be considered the opposite of electron affinity. This is the force required to remove an electron from an atom while it is gaseous, or the propensity of an atom to lose electrons.
What is meant by electron?The electron is a subatomic particle with a negative one elementary charge electric charge. Due to their lack of components or substructure, electrons, which are part of the lepton particle family's first generation, are typically regarded to be elementary particles.
An electron is a negatively charged subatomic particle that can exist either free or bound to an atom (not bound). Along with protons and neutrons, electrons are one of the three primary types of particles that make up an atom. Together, protons, neutrons, and electrons make up the atom's nucleus.
This is the force required to remove an electron from an atom while it is gaseous, or the propensity of an atom to lose electrons. Conceptually, this is the polar opposite of electron affinity.

Which are effects of long-term exposure to mustard gas? Select all that apply. One, some, or all responses may be correct.
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.

9) What is the final pressure in the container shown below after the valve is opened and the gases are allowed
to flow? (The gases do not act)
0
4.00 am
3.00
NE
2.00 am
2.00 L
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.
