Answers
Answer: reflection
Explanation:
A mirror forms an image because of reflection of light. Therefore, the correct option is option B among all the given options.
What is light?Light is the electromagnetic radiation that is visible with the eye. Electromagnetic radiation has a very broad wavelength range, ranging from gamma rays having wavelengths shorter than around 1 1011 metre to radio waves with wavelengths measured in metres.
The spectral areas next to the visible band, infrared at one end as well as ultraviolet at the other, are often commonly referred to as light. The velocity of light in the vacuum is indeed a basic physical constant, with the current accepted value being 299,792,458 meters per second, or approximately 186,282 miles a second. A mirror forms an image because of reflection of light.
Therefore, the correct option is option B.

In the reaction C + O2 → CO2, 18 g of carbon react with oxygen to produce 72 g of carbon dioxide. What mass of oxygen would be needed in the reaction?
18 g
54 g
72 g
90 g
Answers
Answer:
54 g
Explanation:
Given data:
Mass of carbon = 18 g
Mass of CO₂ = 72 g
Mass of oxygen needed = ?
Solution:
Chemical reaction:
C + O₂ → CO₂
according to law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
In a similar way,
C + O₂ → CO₂
18 g + X = 72
X = 72 -18
X = 54 g
Thus, 54 g of O₂ are required.

54g

When solid S1 is heated, it breaks up into gas G and another solid S2. The solids S1 and S2 and the gas G are all pure substances. On the basis of this information alone, which substance or substances must be compounds? A.S1 only B.S2 only C.S1 and S2 D.S1 and G
Answers
Answer:
A.S1 only
Explanation:
A compound is one of the pure substances (other being element) that forms when two or more atoms of an element are chemically combined. According to this question, a solid S1 is heated and it breaks up into gas G and another solid S2 as follows:
S1 (s) ➡ G (g) + S2 (s)
Based on the information in the questio, the solids S1, S2 and the gas G are all pure substances. However, since solid S1 broke down into two other pure substances, it means solid S1 is originally a chemical combination of both products, which denotes a COMPOUND. Note that Gas G and Solid S2 are most likely elements.

Answer:
Explanation:
proposed an early model of the atom as a central nucleus containing protons and neutrons being orbited by electrons in shells. As previously discussed, there is a connection between the number of protons in an element, the atomic number that distinguishes one element from another, and the number of electrons it has. In all electrically-neutral atoms, the number of electrons is the same as the number of protons. Each element, when electrically neutral, has a number of electrons equal to its atomic number.

A paint chip is placed in ethanol and curls what type of paint is it
Answers
Answer:
it is probably acrylic or latex
Explanation:
There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, the type of paint is acrylic or latex.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
An ionic compound is a metal and nonmetal combined compound. Ionic compound are very hard. They have high melting and boiling point because of strong ion bond. If the chip remains flat when put in ethanol, it is probably an oil-based paint. If the chip curls, it is probably acrylic or latex. So, The type of paint is acrylic or latex.

Molecular orbital diagram for Fe.
Answers
ANSWER;
1s22s22p63s23p63d64s2
EXPLANATION;
Molecular orbital diagram for Fe.
In writing the electron configuration for Iron the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Iron go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the next two electrons in the 3s. Since the 3s if now full we'll move to the 3p where we'll place the next six electrons. We now shift to the 4s orbital where we place the remaining two electrons. After the 4s is full we put the remaining six electrons in the 3d orbital and end with 3d6.
Therefore the Iron electron configuration will be 1s22s22p63s23p64s23d6.
Note that when writing the electron configuration for an atom like Fe, the 3d is usually written before the 4s. Both of the configurations have the correct numbers of electrons in each orbital, it is just a matter of how the electronic configuration notation is written
Therefore we have 1s22s22p63s23p63d64s2

The product of the process of photosynthesis is sugar and the energy to dive the process of photosynthesis comes from sunlight.
What is photosynthesis?Photosynthesis is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

How many protons, neutrons, and electrons does 35/17 Cl ^ 1- have?
Answers
Answer:
In accordance to the pic
The number of protons in Cl-35 is 17 and the number of neutrons is 18. The number of Cl is 17 whereas the chloride ion Cl⁻ have 18 electrons.
What is chlorine?Chlorine is 17th element in periodic table. Cl is includes in the 17th group of p -block. Cl contains 7 valence electrons and it needs one more electron to attain complete configuration. It is highly electronegative and will easily gain an electron to achieve octet.
Atoms in neutral state have equal number of electrons and protons and this number is equal to the atomic number. The mass number is the sum of number of protins and neutrons.
The atomic number of Cl is 17. Hence the number of protons is 17 and the mass number is 35. So that number of neutrons is 35 - 7 =18. When Cl gains an electron it forms the anion Cl⁻. Hence, the number of electrons in Cl⁻ is 18.
