A hurricane can cause destruction at a high scale2) winds blowing from high pressure to low pressure
when the clouds take up the hot vapours , making the atmosphere warm ,the pressure increases resulting in formation of wind and when these winds wind up to make a huge pattern which we call hurricane3) Clock wise rotation
The clockwise rotation moving a same direction helps to make the eye visible to usHow is temperature related to the physical change of a
substance?
Answer:
Physical conditions like temperature and pressure affect state of matter. ... When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation)
Answer:
Temperature is a measure of the kinetic energy of particles in a substance. As temperature increases, the atoms or molecules in a substance gain energy. As temperature decreases, the particles lose energy. A change in the energy of particles causes a change in their arrangement. A change in the arrangement of particles can lead to a physical change.

The oxidation state of iron changes from 0 to +3, and of oxygen changes from 0 to -2.
What is oxidation state?Oxidation state of any atom will tells about the number of exchangeable electrons.
Given chemical reaction is:
Fe + O₂ → Fe₂O₃
Initially in the reactant form, oxidation state of iron (Fe) atom and oxygen (O₂) molecule is zero as they are in elemental form. Oxidation state of 2 iron atoms in the product (Fe₂O₃) is +3 as it is combined with the 3 atoms of oxygen whose oxidation state is -2.
Hence, oxidation state of Fe and oxygen changes as we going from reactants to product side.

An old iron battery was discarded in this meadow. The iron in the battery is undergoing a ____ change as it rusts. The rusting is changing the battery's color from black to orange. A) physical B) chemical C) environmental D) none of these changes are occurring
Answer:
chemical
Explanation:
A chemical change is irreversible and leads to the formation of new products.
Rusting occurs as a result of an irreversible chemical reaction between iron, oxygen and moisture. Rusting is the oxidation of iron when exposed to oxygen and moisture.
The rusting of iron is an electrochemical process in which water serves as the electrolyte and iron serves as the anode. The rusting of iron leads to the formation of hydrated iron III oxide (rust) usually seen an brown flakes that surround a rusted iron material.

Which statement is true about the exothermic reaction?
A.) The enthalpy of the products is greater than that of the reactants.
B.) The enthalpies of the reactants and the products are equal.
C.) The enthalpy of the reactants is greater than that of the products.
Answer:
C
Explanation:
The enthalpy of the reactants is greater than that of the products.
The statement is true about the exothermic reaction is the enthalpy of the reactants is greater than that of the products. Therefore, option C is correct.
What is an exothermic reaction ?A chemical reaction involves the movement of energy to or from the environment. An exothermic reaction occurs when energy is transmitted to the environment, raising the ambient temperature. Combustion reactions are an example of an exothermic reaction.
Chemical processes known as exothermic reactions generate heat. Therefore, the H of reaction is negative for exothermic processes. Heat is released during an exothermic reaction, raising the temperature of the immediate environment. The environment is cooled through an endothermic process that absorbs heat.
Heat is released during an exothermic reaction, raising the temperature of the immediate environment. The environment is cooled through an endothermic process that absorbs heat.

The chemical equation below shows the reaction between carbon dioxide (CO2) and lithium hydroxide (LiOH). CO2 2LiOH Right arrow. Li2CO3 H2O The molar mass CO2 is 44. 01 g/mol. How many moles of LiOH are needed to react completely with 25. 5 g of CO2? 0. 290 moles 0. 579 moles 1. 16 moles 1. 73 moles.
Answer:
C
Explanation:
The reaction between carbon dioxide and lithium hydroxide can be represented by the equation:
[tex]\displaystyle \text{CO$_2$} + 2\text{LiOH} \longrightarrow \text{Li$_2$CO$_3$}+ \text{H$_2$O}[/tex]
We want to determine the amount of moles of LiOH needed to react completely with 25.5 g of CO₂.
Determine the number of moles of CO₂ in 25.5 g of CO₂:
[tex]\displaystyle 25.5\text{ g CO$_2$} \cdot \frac{1\text{ mol CO$_2$}}{44.01\text{ g CO$_2$}} = 0.579\text{ mol CO$_2$}[/tex]
Use stoichiometry to determine the amount of LiOH necessary. CO₂ and LiOH are in a 1:2 ratio. That is, for every one mole of CO₂ that reacts, two moles of LiOH must also react.
[tex]\displaystyle 0.579\text{ mol CO$_2$} \cdot \frac{2\text{ mol LiOH}}{1\text{ mol CO$_2$}} = 1.16\text{ mol LiOH}[/tex]
In conclusion, our answer is C.
Solid zinc and aqueous lead (II) nitrate react to from aqueous zinc (II) nitrate and solid lead.
Zn(s) + Pb(NO₃)₂ (aq) → Zn(NO₃)₃ (aq) + Pb (s)
Further explanationThere are two types of chemical reactions that may occur.
single-replacement reactions and double-replacement reactions.
A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
A + BC ⇒ AC + B
Not all of these reactions can occur. We can use the activity series, which is a list of elements that can replace other elements below / to the right of them in a single replacement reaction.
This series is better known as the Volta series, where the metal element with a more negative electrode potential is on the left, while the element with a more positive electrode potential on the right.
The more left the position of a metal in the series, the more reactive metal (easy to release electrons)
Generally, the Volta series used is
Li K Ba Sr Ca Na Mg Al Mn Zn Cr Fe Cd Co Ni Sn Pb H Sb Bi Cu Hg Ag Pt Au
Solid zinc and aqueous lead (II) nitrate react to from aqueous zinc (II) nitrate and solid lead.
Can be expressed in chemical equations :
Zinc + aqueous lead (II) nitrate ⇒aqueous zinc nitrate + lead metal
Zn(s) + Pb(NO₃)₂ (aq) → Zn(NO₃)₃ (aq) + Pb (s)
Reactants : Zn and Pb(NO₃)₂
Products : Zn(NO₃)₃ and Pb
The existing Zinc element can replace the Lead element, which is on the right side of Zn, so the reaction will occur.
Which of the following could make a decomposition reaction occur?
heat or light
time
nothing needed for most to proceed
Heat or light could make a decomposition reaction occur. Therefore, option (A) is correct.
What are decomposition reactions?
The decomposition reactions can be described as in which one reactant breaks into one or more products during the reaction.
The decomposition reaction can be represented as the following equation:
AB → A + B
Where AB is the parent molecule that acts as a reactant and gives A and B as products.
A decomposition reaction can be possibly an exothermic reaction or endothermic reaction. Thermal decomposition reactions are those in which the energy is supplied to reactant molecules for the decomposition.
For example, the decomposition of calcium carbonate is a thermal decomposition reaction. In the products, carbon dioxide gas and calcium oxide are produced. The decomposition of ozone gas occurs in the presence of light.
Therefore, heat or light can make the decomposition reaction take place.

What is the main difference between Lewis structure and Bohr models?
The main difference between both models is that the Bohr model depicts all subatomic particles, but the Lewis dot diagram only depicts the symbol and valence electrons.
What is Lewis structure?Lewis Structure is a simplified representation of a molecule's valence shell electrons. It's used to depict how electrons in a molecule are distributed around specific atoms.
Electrons are shown as "dots" or as a line between two atoms when they are bonded in Lewis structure.The Bohr Model is a planetary model in which negatively charged electrons orbit a tiny, positively charged nucleus in the same way that planets orbit the sun.Hence the Bohr model depicts all subatomic particles, but the Lewis dot diagram only depicts the symbol and valence electrons.
