how do you think the atoms in metal element are different from those in nonmetals or metalloids
Answer:The atoms of metallic elements are different from the atoms of non metals or metalloids base on the outer electron/ valency electrons and the its bonding pattern.
The atoms of different metals varies in it ability to bond quickly.
The atoms of metallic elements are different from the atoms of non metals or metalloids base on the outer electron/ valency electrons and how it bonds.
Metallic atoms have very few electrons in the outermost shell. The valency electrons of this metallic atoms are few and are easily lost during bonding. They have the ability to release there valency electrons easily. Example of this metals are sodium, potassium , calcium etc.
On the other hand non metallic elements have numerous electron in the outermost shell and easily receive electron during bonding. Example are chlorine, fluorine, oxygen etc.The metalloid atoms like silicon and germanium have an average number of electron in their outermost shell. They are in between.
The atoms of different metals varies in it ability to bond quickly. For example the group 1 metals are very reactive than the group 2 metals. This simply means the group 1 metals(alkali metals) goes into bonding more easily than the group 2 metals(alkali earth metals).

What splitting pattern is observed in the 1H NMR spectrum for the indicated (BOLD) hydrogen (on carbon
Number many peaks are present in the ¹H-nmr spectrum of Eugenol are having 12 different hydrogen atom.
How many peaks are present in the 1h-nmr spectrum of Eugenol?The Eugenol has contain the 12 different hydrogen atoms. in the ¹H-nmr spectrum the peaks from right to left is 3:2:2:3:2. The three hydrogen atoms have two peaks of about the 6.7 pm.The integral of 2H means that this group is a methylene, so it has two hydrogens. The carbon bearing these two hydrogens can have two other bonds. Another type of additional data available from 1H NMR spectroscopy is called multiplicity or coupling. Coupling is useful because it reveals how many hydrogens are on the next carbon in the structure. That information helps to put an entire structure together piece by piece.In ethanol, CH3CH2OH, the methyl group is attached to a methylene group. The 1H spectrum of ethanol shows this relationship through the shape of the peaks. .This pattern is called a multiple, and specifically a quartet. A quartet means that these hydrogens have three neighbouring hydrogens on adjacent carbons.

Include:
- Particles in plasmas collide more often.
- Plasma particles have high kinetic energy (they move quickly).
- Plasma particles are far apart.
- The ionized particles have no fixed volume
Plasma is a state of matter. It was once considered as a subset of gas. But it is an entirely different state with its own characteristics.
Plasma is superhot, so that all the atoms are ripped apart from its electrons and is in an ionized state. But gas particle contains mostly neutral particles of the gas. Like we heat a liquid to produce gas, we heat gas to form plasma.
Plasma can conduct electricity due to the presence of charged particles. Plasma can be held in a place by using magnetic forces. By disturbing the magnetic field inside the plasma it emits a wave called Alfven wave, which is only characteristic to plasma.
The charged particles moves at high speed towards the poles of the magnetic field and due to its collision with each other, excites gases like nitrogen and oxygen and emits neon like lights. Most plasma's are not dense enough for particles to collide with each other, this is where electrical and magnetic field comes to play.
So plasma is formed from superheated gases, which have ionized particles, rather than neutral atoms, which are less denser, conductive, and in presence of electrical or magnetic field, emits waves that are characteristic only to plasma.

[tex]\boxed{\large\textsf{$\sf\displaystyle number\ of\ moles\ (mol)=\frac{mass\ present\ (grams)}{molar\ mass\ (g/mol)}$}}[/tex]
Rearranging this formula to find mass, therefore, mass present = number of moles ÷ molar mass:

Since we are already given the number of moles of HNO₃ present, we just need the molar mass. The molar mass of elements can be found on any standard periodic table, and the molar mass of a compound is just the sum of all the molar masses of the elements in the compound.
∴ molar mass HNO₃ = H (1.008) + N (14.01) + O₃ (3×16.00) = 63.02 g/mol.

Based on the proposed mechanism, which of the following best describes the concentration of the species represented above as the reaction occurs?answer choicesThe concentration is larger than that of reactant or product.The concentration is very low for the duration of the reaction.The concentration fluctuates between high and low during the reaction.
Answer: The concentration fluctuates between high and low during the reaction.
Explanation: In a chemical reaction, the reactants are converted into products and the concentrations of the species involved in the reaction change over time. The proposed mechanism describes how the reaction occurs, and it can give an insight into how the concentrations of the species change during the reaction.
When the reaction starts, the concentration of reactants is high, and the concentration of products is low. As the reaction progresses, the reactants are consumed, and the products are formed. The concentration of reactants decreases, and the concentration of products increases.
At some point, the rate of the forward reaction is equal to the rate of the reverse reaction, and the reaction reaches equilibrium. At equilibrium, the concentrations of the reactants and products remain constant, and the reaction proceeds at a steady state.
Therefore, based on the proposed mechanism, the concentration of the species represented in the equation fluctuates between high and low during the reaction, as the reactants are consumed, and the products are formed, until reaching the equilibrium state.

It is similar to a molecular equation in which compounds are expressed as molecules. Chemical equations known as ionic equations only display the ions involved in a chemical reaction. Or, the ions that combine in a solution to react and create new substances. Those ions that don't take part are referred to as spectator ions. A chemical equation known as an ionic equation expresses the electrolytes in aqueous solution as dissociated ions. The ionic species are usually followed by (aq) in the equation to denote that they are in an aqueous solution, and this is typically a salt that has been dissolved in water.
Here,
The precipitation reaction between silver nitrate solution and sodium sulfide solution is represented by the net ionic equation 2Ag[+](aq) + S[2-] -> Ag{2}S(s).

When calcium carbonate is heated, it breaks down into calcium oxide and carbon dioxide. caco3(s) →cao(s) co2(g) you heat 2.0 moles caco3. how many moles of carbon dioxide(co2) will you make?
Moles of carbon dioxide(co2) will you make only 0.0115 mol was produced.
we know the ideal gas equation,
PV = nRT
PV/RT=n
n=(1.04 atm)(1.00 L) /L atm (0.0821 )(1100 K) mol K
n=0.0115 moles of CO2.
The moles ofCaCO3 = 50.0 g/100.09 g/mol = 0.500 mol CaCO3 .If the reaction had gone to completion, 0.500 mol of CO2 would have been produced. The two different experiments (one with 50.0 g of CaCO3 and one with 100.0 g of CaCO3) reached the same constant, final pressure of 1.04 atm.
Since increasing the amount of reactant did not produce more product, there is no way that all of the CaCO3 reacted. Instead, an equilibrium condition has been achieved and there must be some solid CaCO3 in the container.
