Explanation:
Which of the following is NOT a conductor of heat?
A. a plastic pot handle
B. a copper pan
C. a metal spoon
A) A plastic pot handle.
Explanation:Metals are very good conductors of heat because they contain delocalised electrons that can flow through the metal, transferring heat.
Both a copper pan and a metal spoon are made of metals, so are very good conductors of heat.
Plastic is an insulator, the opposite of a conductor. This makes it very bad at conducting heat, which is why it is used as the handle (it stops you burning yourself when you hold the pot). The answer is therefore A.

Multiple choice question. the endothermic process results in a precipitation of a crystalline solid from a liquid solution the endothermic process converts a gas reactant into a liquid or solid product the product particles have more freedom of motion than the reactant particles the product particles have less freedom of motion than the reactant particles
An endothermic process may be spontaneous if: C. the product particles have more freedom of motion than the reactant particles.
An endothermic reaction can be defined as a type of chemical reaction in which heat energy is absorbed from the environment.
Generally, heat energy is absorbed in a chemical reaction when the energy of the products is greater (more) than the energy of the reactants and this is referred to as an endothermic reaction.
Similarly, an endothermic process may be spontaneous when the product particles have more freedom of motion than the reactant particles.

Refer to the following balanced equation in which ammonia
reacts with nitrogen monoxide to produce nitrogen and
water.
4NH3(g) + 6NO(g) → 5N2(8) + 6H2O(l)
How many moles of NO are required to completely react with
2.45 mol NH3 ?
4NH₃(g) + 6NO(g) → 5N₂(8) + 6H₂O(l)
The mole ratio of NO to NH₃ based on the balanced equation is 6 to 4 (or 3 to 2 in the simplest form)
Therefore in the reaction, there are ³/₂ more moles of NO than NH₃.
⇒ since moles of NH₃ = 2.45 mol
then moles of NO = 2.45 mol × ³/₂
= 3.675 mol

Explanation:
An exothermic reaction is defined as a reaction that releases heat and has a net negative standard enthalpy change. Examples include any combustion process, rusting of iron, and freezing of water.
The combustion is an example of an exothermic reaction.
An exothermic reaction is a reaction that releases energy, this energy is usually in the form of heat. An endothermic reaction is a reaction that absorbs energy to take place.
Analyzing the given reactions we have that:
Evaporation: need to absorb energy to increase the kinetic energy of the moleculesMelting ice: need to absorb energy to increase the kinetic energy of the moleculesCombustion: releases energy after forming bonds between moleculesDecomposition: need to absorb energy to break moleculeSo, the combustion is an example of an exothermic reaction.

In a crystal of an ionic compound, each cation is surrounded by a number of what?
Answer:In a metal, atoms readily lose electrons to form positive ions (cations). These ions are surrounded by delocalized electrons, which are responsible for conductivity.
Explanation:
Due to the structure of ionic compounds, in a crystal of an ionic compound, each cation is surrounded by a number of oppositely-charged anions.
What are ionic compounds?Ionic compounds are compounds that are composed of oppositely charged ions held together by strong electrostatic forces of attraction.
The ions present in an ionic compound are the positively-charged ions known as cations and the negatively-charged ions known as anions.
Each of the oppositely-charged ions are attracted to each other.
Therefore, in a crystal of an ionic compound, each cation is surrounded by a number of oppositely-charged anions.

Which ground-state atom has an electron configuration described by the following orbital diagram?.
Answer:
The energy of atomic orbitals increases as the principal quantum number, n, increases. In any atom with two or more electrons, the repulsion between the electrons makes energies of subshells with different values of I differ so that the energy of the orbitals increases within a shell in the order s< p <d<f. Figure 1 depicts how these two trends in increasing energy relate. The 1s orbital at the bottom of the diagram is the orbital with electrons of lowest energy. The energy increases as we move up to the 2s and then 2p, 3s, and 3p orbitals, showing that the increasing n value has more influence on energy than the increasing I value for small atoms. However, this pattern does not hold for larger atoms. The 3d orbital is higher in energy than the 4s orbital. Such overlaps continue to occur frequently as we move up the chart.

Write the empirical formula of at least four binary ionic compounds that could be formed from the following ions: Ca2+, Al3+, Cl−, O2−
Answer:
CaCl2
CaO
Al2O3
AlCl3
You can do this by swapping the values of charges on the ions as below
eg- Ca2+ - 2
Cl- - 1
Now combine 1 Ca atom and 2 Cl atoms and it will give you CaCl2
Al 3+ - 3
O2- - 2
Combine 2 atoms of Al and 3 atoms of O
Al2O3
In the case of CaO, we have to make sure that the atoms are in their simplest ratio. So although we get Ca2O2, CaO is the correct form

The statement which best describes the hydrogen and oxygen atoms in
water is that the lone pairs of electrons in the oxygen atom causes the
molecule to be bent; the oxygen atom has a partial negative charge, while
the hydrogen atoms have partial positive charges.
Water is a compound which comprises of the elements hydrogen and
oxygen. They share electrons in the covalent bond present between the
atoms. The sharing of electrons isn't equal which is why it has a bent
structure.

why are water-soluble vitamins less likely to be toxic compared to fat-soluble vitamins?
Answer:
Water-soluble vitamins are not stored in the body and are excreted in the urine quickly. Unlike water-soluble vitamins, fat-soluble vitamins are dissolved in fat and an excess of them would lead to toxicity if consumed in large amounts because it would lead to rancidity, and they are not easily excreted by urine like water-soluble vitamins.
Even when consumed in high doses, water-soluble vitamins are less likely to create problems since they are eliminated through urine rather than stored.
What are vitamins?Vitamins are defined as a collection of molecules required for healthy cell growth, development, and function. While some vitamins support healthy neurons and infection resistance, others may aid in correct blood clotting or food energy absorption.
Water-soluble vitamins are promptly eliminated in the urine and are not retained by the body. In contrast to water-soluble vitamins, which are easily eliminated by urine, fat-soluble vitamins are dissolved in fat. If ingested in excess, they can be harmful due to rancidity and cannot be easily expelled through urine.
Thus, even when consumed in high doses, water-soluble vitamins are less likely to create problems since they are eliminated through urine rather than stored.
