n E Which is the electron configuration for zinc? O 1s22s22p3s23p64s23d8 O 1s22s22p 3s 3p64s+3d10 01s 2s 2p 3s 23p64523d10 0 1522s 2p 3s23p64533d10
The electronic configuration is used to explain the orbitals of an atom and it helps to determine the physical and chemical properties of the elements. The electronic configuration of zinc is 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰. The correct option is C.
What is electronic configuration?The distribution of electrons in the atomic orbitals is given by the electronic configuration. It is a standard notation in which all the electrons holding atomic subshells are arranged in a sequence. Each element has a unique electronic configuration.
The electronic configuration of an element can be written in two ways, in standard notation, and in condensed form. In the case of elements with larger atomic numbers, the electronic configuration becomes lengthy in standard notation. So in such cases condensed form is generally used.
In condensed form electronic configuration of zinc is [Ar] 3d¹⁰4s² and in standard form it is 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰.
Thus the correct option is C.

Answer:
50 mL; 7
Explanation:
By looking at the graph, the boundary point where the solution turns from acidic to basic appears at approximately 50 mL.
Because this is a titration between a strong acid and strong base, the pH of the equivalence point is always 7 (aka neutral).

O B. They both use ATP energy to produce radiant energy.
C. All of their chemical products are gases found in the atmosphere.
O D. The chemical products of one are the reactants of the other.
Answer: D. The chemical products of one are the reactants of the other.
I just took the quiz
Cellular respiration and photosynthesis related as the chemical products of one are the reactants of the other and the correct option is option D.
What is the difference between Respiration and Photosynthesis?Respiration is something that occurs in all living organisms. Thus, it is a process that converts oxygen and glucose into carbon dioxide and water and ultimately makes energy for your body cells.
On the other hand, photosynthesis takes place in green plants that contain chlorophyll. In this process, they make use of sunlight and water for converting it into energy.
Plants release oxygen which is a by-product of photosynthesis, and we breathe in oxygen so that our cells can carry out cellular respiration and generate ATP.
Therefore, Cellular respiration and photosynthesis related as the chemical products of one are the reactants of the other and the correct option is option D.

Luisa likes to drink water from a plastic bottle. She knows the bottles were formed from synthetic polymers that were created in a chemical reaction.

Complete question: Luisa likes to drink water from a plastic bottle. She knows the bottles were formed from synthetic polymers that were created in a chemical reaction. She also knows that synthetic materials can cause problems. Which statement explains the kind of problem that can develop from using synthetic materials such as plastics?
a) plastics have changed the way people use materials
b) plastics have made the lives of people easier
c) plastics have contributed to more pollution
d) plastics have made more work for people
Answer: The correct statement is plastics have contributed to more pollution. Option C.
Explanation:
Synthetic polymers are commonly called plastics. These are referred to as synthetic materials which can be softened by heat or pressure and then moulded into any desirable shape like the the plastic bottle Luisa drank from.
The raw materials for the manufacture of plastics are readily and cheaply available for the refinement of crude oil through series of chemical reactions. They are made by polymerization of monomers which are derived from petrochemicals.
Although they are used in producing materials used daily, it has contributed to more pollution over the years. POLLUTION is the release of chemicals or substances through man's activities, into the environment which causes harm to both man and the environment.
Plastics have contributed to more pollution because most plastics are non- biodegradable and cannot be broken down by microbial action into simple inorganic forms. Therefore, they cause severe land pollution problems since they are not easily disposable. Also is poses a major problem to the world supply of crude oil as it's limited. This is as a result of heavy dependence on crude oil which provides petrochemicals that is the bulk of the raw materials needed for making plastics.

Answer: 824.6 g of NaCl are produced from 500.0 g of chlorine.
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex] [tex]\text{Moles of} Cl_2=\frac{500.00g}{71g/mol}=7.04moles[/tex]
[tex]2Na+Cl_2\rightarrow 2NaCl[/tex]
According to stoichiometry :
1 mole of [tex]Cl_2[/tex] produce = 2 moles of [tex]NaCl[/tex]
Thus 7.04 moles of [tex]Cl_2[/tex] will produce=[tex]\frac{2}{1}\times 7.04=14.08moles[/tex] of [tex]NaCl[/tex]
Mass of [tex]NaCl=moles\times {\text {Molar mass}}=14.08moles\times 58.5g/mol=824.26g[/tex]
Thus 824.6 g of NaCl are produced from 500.0 g of chlorine.
3. Add labels for mass extinction and adaptive radiation:
Answer:
I'm assuming you need to label above the lines. So, above the line where the Cretaceous period ends is mass extinction and where the bracket lies is adaptive radiation.
Explanation:
Mass extinctions are periods of time where the organisms are essentially wiped out in an extremely brief period of time. You can see how the species just drops off. Adaptive radiation occurs when there is a diversification of a group of organisms as evident by the rise in the number of marine animal groups shown by the bracketed area.

A light bulb has a resistance of 96.8 Ω. What current flows through the bulb when it is connected to a 120 V source of electrical energy?
Answer:
I = 1.23 A
Explanation:
Given that,
The resistance of the lightbulb, R = 96.8 Ω
Voltage, V = 120 V
We need to find the current flows through the lightbulb. Let the current be I. We can use the ohm's law to find it i.e.
[tex]V=IR\\\\I=\dfrac{V}{R}\\\\I=\dfrac{120}{96.8}\\\\I=1.23\ A[/tex]
So, the current flows through the bulb is 1.23 A.

What method can be used to separate benzoic acid and potassium carbonate
Answer:
To separate the components, a water wash may be attempted to remove benzoic acid, but benzoic acid is not particularly water-soluble due to its nonpolar aromatic ring, and only small amounts would be extracted into the aqueous layer
The method that can be used to separate Benzoic acid and potassium carbonate is : The application of water wash separation method
Benzoic acid is slightly soluble in cold water but becomes more soluble as the temperature of water is increased. Water wash separation method is a methodology used for the selective removal of unwanted compounds in a mixture.
Separation method based on solubility water wash methodprecipitationThe separation of benzoic acid and potassium carbonate is based on the solubility differences between Benzoic acid and potassium carbonate when dissolved in a solvent ( water ) therefore the water wash separation method is the most effective method.
Hence we can conclude that The method that can be used to separate Benzoic acid and potassium carbonate is : The application of water wash separation method.
