C
A
B
Both B and C
Answers
Answer:
C is the answer..
The equation is showing how it is formed, so the answer is on the other side of the equal sign.
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, diagram C shows the final compound.
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.

Answers
Answer:
16.5gm of Sr(strontium) has 1.12 x10^23 atoms...26.5 gm of Fe(iron) has 2.84 x10^23.... 7.73 gm of Bismuth has 2.22 x10^22.....36.4gm of Phosphorus has 7.06 x10^23
Explanation:
by the formula,
Moles=[tex]\frac{no of atoms}{Avogadro's No}[/tex]
you could find moles by
Moles = given mass/atomic mass
Put the value of moles and multiply it by Avogadro's no you will get the following answers

Which of the following d shell configurations is likely to be the best magnet?
Answers
Answer:
D10 is answer
Explanation:
Magnetism can result from unpaired electrons in a given ion of an element, depending on the spin states of the electrons and d10 is fully filled
The d 10 is the d shell configurations which is most likely to be the best magnet.
What are configurations?Configurations are defined as the way that parts are joined together to form the computer system. The arrangement of electrons scattered throughout the orbital shells and subshells is depicted by the electron configuration of an atom. Divide the periodic table into pieces to represent the atomic orbitals, the areas where electrons are stored, in order to determine an electron configuration. The s-block is represented by groups one and two, the d-block by groups three through twelve, the p-block by groups thirteen to eighteen, and the f-block by the bottom two rows.
Depending on the spin states of the electrons and whether or not d10 is completely filled, magnetism can emerge from unpaired electrons in a specific ion of an element.
Thus, the d 10 is the d shell configurations which is most likely to be the best magnet.

AgF (aq) + KNO3 (aq) →
Answers
Answer:
AgF (aq) + KNO₃ (aq) → AgNO₃(aq) + KF(aq)
Explanation:
AgF (aq) + KNO₃ (aq) →
The products from the equation above can be obtained as follow:
1. AgF and KNO₃ will dissociate in solution as shown below:
AgF (aq) —> Ag⁺(aq) + F¯(aq)
KNO₃ (aq) → K⁺(aq) + NO₃¯(aq)
2. A double displacement reaction will occur between AgF and KNO₃ as illustrated below:
AgF (aq) + KNO₃ (aq) →
Ag⁺(aq) + F¯(aq) + K⁺(aq) + NO₃¯(aq) → Ag⁺NO₃¯(aq) + K⁺F¯(aq)
AgF (aq) + KNO₃ (aq) → AgNO₃(aq) + KF(aq)
A careful observation of the above equation shows that the equation is balanced.

In each of the following pairs, circle the form of radiation with the LONGER WAVELENGTH:
A. red light or blue light
B. microwaves or radiowaves
C. infrared radiation or red light
D. gamma rays or UV rays
Answers
Answer:
In the first one in a it is red light in b it is radio waves in c it is infrared radiation and d is UV radiation
Explanation:
The forms of radiation from the pairs listed that have longer wavelength are :
A) Red light
B) Radio waves
C) Infrared radiation
D) UV rays
Red light have a wavelength between 650 to 720 nm while a Blue light has a wavelength of 380nm to 500nm which makes it to produce a high energy visible light.( HEV ) light. therefore the Red light has a longer wavelength.
The wavelength of a microwave is approximately 30 centimeters to 1 millimeter, which makes it shorter than the wavelength of a radio wave ( shortest wavelength in the electromagnetic spectrum.
Hence we can conclude that The forms of radiation from the pairs listed that have longer wavelength are A) Red light B) Radio waves C) Infrared radiation D) UV rays

Autism is a disability that results from a disorder in the central nervous system. It has been speculated that the increasing number of cases of autism in recent years is due to the increase in the number of vaccinations given to young children. What might be another possible explanation for this phenomenon?
Answers
Answer:
Explanation:
As described in the question, autism is a disability that arises from a disorder in the central nervous system which is actually characterized by abnormality in the brain structure and then function. Autism is known for symptoms such as challenges with communication and interaction and some obsessive behaviors. While there is generally no known scientific cause for autism but trends have suggested that vaccination in young children causes autism.
However, genes could also be involved in this phenomenon because there have been reports of unusual genetic sequence in children that have autism. Hence, there is a possibility that vaccination actually triggers this genetic sequence which is then expressed as autism in the children.
Please note this isn't a scientific fact and just a possibility as requested in the question.
