Answers
Answer:
Notice that tellurium is listed before iodine even though its atomic mass is higher. Mendeleev reversed the order because he knew that the properties of iodine were much more similar to those of fluorine (F), chlorine (Cl), and bromine (Br) than they were to oxygen (O), sulfur (S), and selenium (Se).

D. 1:1
Answers
Answer the ratio of Be to At is 1:2 in the compound
Explanation:
Be in Periodic Table 2A has 2 valence electrons in its outer orbital and needs to give them away. When it gets rid of 2 negatives, its charge is +2.
At in Periodic Table 7A has 7 valence electrons in it outer orbitals and needs one more electron. 2 AT atoms each accept one electron from Be and each has a charge of -1. The Be ion of +2 charge is balanced by the two At ions of -1 charge, so the ratio of Be to At is 1:2

the average single and double n-o bond lengths are 136 pm and 122 pm, respectively. assuming these two structures were to make equal contributions to the observed bonding in hno2, predict the n–o bond length.
Answers
Resonance structures show that chemical species have equal bond lengths and bond angles when in resonance. The bond lengths of the N - O bond in HNO2 is 126pm.
Linus Pauling introduced the idea of resonance to explain the nature of bonding in compounds and ions where a single Lewis structure can not satisfactorily account for the observed properties of the chemical species.
If the two structures are resonance structures, they will have equal N - O bond lengths and bond angles. The bond length will be intermediate between that of a pure N - O single and N - O double bond. The actual N- O bond lengths in HNO2 are obtained as; 136 pm - 122 pm/2 = 126 pm.

Answers
Answer: Heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.
A accumulation of static charge inside a storm cloud causes lightning.
What is lightning?Lightning is a massive electrical discharge that originates in the atmosphere between clouds, the air, or the earth.
In a rain cloud, lightning begins as static charges.
At the peak of the cloud, lighter, positively charged particles form. The cloud's heavier, negatively charged particles settle to the bottom. A massive spark, or lightning, develops between the two charges within the cloud when the positive and negative charges get large enough.
Step involved in the forming of lightning:
The collision of water droplets with ice crystals in the upper atmosphere occurs due to the rapid rise of the air. These collisions generate static electricity, which charges the clouds. Huge sparking occurs between the clouds or between the clouds and the ground as a result of this. This is referred to as lightning.
Example, Nylon clothes
Static electricity is produced when nylon clothing is rubbed against another fabric or against the wearer's skin.

What is water wave?Water wave is a type of mechanical wave. Water wave is a transverse wave in which the oscillation of particles is along the direction of wave propagation.
The the water waves are highly energetic and this kinetic energy is converted to electric energy using turbines and generator. The height to the crest of the wave from the base line is called amplitude. As the amplitude increases, energy of the wave is increasing.
Thus, more the amplitude, more the energy of wave leading to greater yield of electrical energy as well. Therefore, option D is correct.

Why does the reactivity of metals increase from right to left on the periodic table? (1 point)
Metals on the right have more valence energy levels, so the ability of the nucleus to attract electrons is reduced,
Metals on the right have more protons, causing valence electrons to be held more strongly
Metals on the right have fewer protons, making it harder to attract electrons from other atoms,
Metals on the right have fewer valence energy levels, so electrons are closer to the nucleus and harder to pull away

Answers
Taking into account the definition of reactivity, the correct option is the first option: Metals on the right have more valence energy levels, so the ability of the nucleus to attract electrons is reduced.
Reactivity is a measure of the probability that a chemical species will participate in a chemical reaction to form chemical bonds.
In other words, the reactivity of a chemical element is the tendency that this element has to combine with others.
For elements that behave like metals, this trend is directly related to the ease with which they lose their valence electrons.
Valence electrons are those electrons farthest from the nucleus of the atom. These electrons are easier to remove because they are the least attracted to the nucleus. Thus, less and less energy is needed to start these valence electrons, so they can commonly participate in the formation of chemical bonds.
In other words, as the size of the metal atoms in a group increases, so does their reactivity.
Then, the correct option is the first option: Metals on the right have more valence energy levels, so the ability of the nucleus to attract electrons is reduced.

While considering boiling point elevation and freezing point depression a solution concentration is expressed in molality and not in molarity?why?
Answers
Answer:
Colligative properties are physical properties of solutions, like boiling point elevation and freezing point depression. In these calculations, the temperature of the solution is changing as we add more solute to the solvent, so this means that the volume of the solution is changing. Since molarity is moles solute per liter of solution, we cannot use molarity as our concentration unit. This is why we use molality (moles solute per kg of solvent) since the kg of solvent doesn't change with temperature.
Explanation:
First in boiling point elevation and freezing point depression, we deal with the system whose temperature is not constant. Second we cannot express the concentration of the solution in mortality because it changes with temperature whereas mortality is temperature independent. Therefore, while considering boiling point elevation and freezing point depression a solution concentration is expressed in mortality and not in mortality.

How do valence electrons impact the type of bonds an atom makes?
An atom wants an empty outer shell of valence electrons, so it will either transfer or share electrons depending on what the other atom needs.
A large number of valence electrons means the atom will share electrons; a small number of valence electrons leads to transferring from one atom to another.
A small number of valence electrons means the atom will share electrons; a large number of valence electrons leads to transferring from one atom to another.
An atom wants a full outer shell of valence electrons, so it will either transfer or share electrons depending on what the other atom needs.

Methane’s chemical formula is CH4. Is there a bond between any of the hydrogen atoms? Why or why not?
Yes, there is because there are one too many hydrogen atoms for carbon to handle alone, so one hydrogen must bond with another.
No, there is not because carbon needs four bonds, so it bonds with each hydrogen atom; hydrogen only forms one bond.
No, there is not because it would form H2 instead of methane if hydrogen bonded with itself.
Yes, there is because they form a long chain in order to all have stable outer energy shells.
