how do you think the atoms in metal element are different from those in nonmetals or metalloids

Answer:The molecular formula is C5 H10 O5 .

Explanation:

The molarity of the solution will be 0.4M.

The unit of measurement for a chemical compound is the mole. The term "molarity" in science refers to a substance's concentration, which is determined by dividing its molecular mass by the volume of the solution it is in.

As given,

Weight of NaOH =  4g

Molecular weight of NaOH = 40 G

Volume of the solution is 250ml

Molarity = ?

M = (W / MW ) × (1000 / V(in ml))

M = ( 4 / 40) ×  (1000 / 250)

0.4M

The pairs of elements which forms covalent bonds. P and S are the elements which forms iconic bond are D. Mg and o.

An ionic bond that is produced between metallic and non-metallic atoms, here the electrons are completely transferred from one atom to another in this process. During this process, one atom loses electrons and another one gains them in this process, forming ions. The metal gives up the electrons forming a cation which results in nonmetal element, which forms an anion. In this process the octet rule is fulfilled which means that this rule states that each atom in a molecule requires 8 valence electrons (in the last layer) to remain stable.

The covalent bond can be defined as the chemical bond between atoms where electrons are shared,  forming a unit called molecule. Covalent bonds are the ones that are established between non-metallic elements, like hydrogen H, oxygen O and chlorine Cl. These elements have electrons in the outermost level and have a tendency to gain electro which acquire the stability of the electronic structure of the noble gas like He.  In other words, sharing electrons, non-metallic elements must lose or gain in order to comply with the Octet rule.

The pressure of the gas can be determined using ideal gas equation. The pressure of neon in the tank is 9.7 atm.

Ideal gas equations states the relation between volume, pressure, temperature and number of moles of gas as written below:

PV = nRT.

Where R is the universal gas constant equal to 0.082 L atm/K mol.

Given the volume of the tank  V = 10 L

number of moles n = 4 moles

temperature  = 22 ° C = 295 k

Then pressure P = nRT/V.

Pressure of neon gas = 4 moles × 295 K× 0.082 L atm/K mol /(10 L)

P = 9.7 atm.

Option C: Neutron is the subatomic particles that could be changed without changing the identity of the atom.

The number of protons in an atom is indicated by the atomic number. As a result, when the amount of protons changes, the atomic number also changes, changing the element's identity. An element's atomic mass changes when its neutron count is altered, but its identity is preserved. An element's charge changes as its electrons are lost or acquired, but its identity is unaffected. Thus, option C is the correct choice.

Protons, neutrons, and electrons are the three subatomic particles that make up an atom. Neutrons are neutrally charged particles, whereas protons are positively charged. The opposite of this is true of electrons, which have a negative charge. Protons and neutrons are found in the nucleus of an atom.

The appropriate law for this problem is Graham's Law of Effusion and Diffusion.

Appropriate law is the legal framework and regulations that are established to ensure fairness and justice within a society. It defines the rights and responsibilities of individuals, businesses, and governments, and helps to promote the public good.

Graham's Law states that the rate of effusion or diffusion of a gas is inversely proportional to the square root of its molecular weight. This means that the lighter the gas, the faster the rate of effusion or diffusion. In this case, u-235 has an atomic mass of 235 g/mol, while u-238 has an atomic mass of 238 g/mol. This makes u-235 the lighter gas, so it will diffuse faster than u-238. Therefore, the answers to the questions are:

u-235 diffused 1.01 times faster than u-238

u-235 effused 1.01 times slower than u-238

700 ml of 10% salt solution and 700 ml of 90% water should the chemist use to make 1400 ml of a solution that is 6% salt.

In chemistry, a solution is a homogeneous combination of two or more compounds in their relative proportions. The composition of the solution can be continually changed up to the solubility limit. Although the term "solution" is frequently used to refer to the liquid state of matter, mixtures of gases and solids are also possible.

When one material dissolves, or separates into another, a solution is created. Solute refers to the material that dissolves to create a solution. A solvent is a substance that helps a solute dissolve. Water serves as the solvent and sugar as the solute in a sugar-water solution.

Given that,

Total solution = 1400 ml

now, x + y = 1400 ....... (i)

Here, x = salt in ml

y = water in ml

Next, 10% salt and 90% water for one solution

another solution that is only 2% salt

Thus, 0.1x + 0.02y = 1400

x + 0.2y = 840 ....... (ii)

2.395 grams of lithium hydroxide are needed to completely neutralize 500 ml of a 0.2 m solution of HCl.

A chemical reaction between an acid and a base that results in a more neutral solution is known as a neutralization reaction. The strength of the acid and base used in the reaction determines the pH of the solution.

For the neutralization reaction: LiOH + HCl -> H2O + NaCl

To find the number of moles of HCl present in the solution:

0.2M * 0.5L = 0.1 moles of HCl

As the reaction is a neutralization reaction, the number of moles of HCl will be equal to the number of moles of LiOH used in the reaction.

Now, we know the number of moles of LiOH used in the reaction is 0.1 moles.

To find the mass of LiOH used in the reaction, we can use the formula: mass = moles * molar mass

The molar mass of LiOH is 23.95 g/mol.

mass = 0.1 moles * 23.95 g/mol = 2.395 g of LiOH.

Therefore, 2.395 grams of lithium hydroxide are needed to completely neutralize 500 ml of a 0.2 m solution of HCl.
