mic numbers of the ions are S (16), Cl (17), K (19), and Ca (20). Thus, the ions DECREASE in SIZE in the order S2– > Cl– > K+ > Ca2+.

Explanation:An example of EQUILIBRIUM is in economics when supply and DEMAND are equal. An example of equilibrium is when you are calm and steady. An example of equilibrium is when hot air and cold air are entering the ROOM at the same time so that the overall temperature of the room does not CHANGE at all

1-the NET force in all directions MUST be zero.2-The state of a body at rest or in uniform motion, the resultant of all FORCES on which is zero.

The TOTAL ENERGY of the ELECTRONS in this carbon atom can not be lowered by transfering one or more electrons to different ORBITALS. Therefore, this carbon atom is a ground-state atom.

What is the NUMBER of moles in 1 g carbon? 1 MOLE = MOLAR mass of carbon = 12 g. 1 g carbon = 1/12 mole = 0.084 mole.

The KEY DIFFERENCE between chemical equilibrium and dynamic equilibrium is that the chemical equilibrium describes the state at which concentrations of REACTANTS and products do not UNDERGO any CHANGE whereas the dynamic equilibrium describes the state at which ratio of reactants and products do not change, but substances move between the chemicals at an equal rate.

Elemental carbon is a BLACK, dull-looking SOLID that conducts heat and electricity well. It is very brittle and cannot be made into THIN SHEETS or LONG wires.

1. 4) 34°C As ethanol have HYDROGEN bonding, it have higher BOILING POINT than diethyl ether2. 4) POCl3C2H5-O-C2H5 + PCl5 --- 2C2H5Cl + POCl3 3. 1) C2H5OC2H5As ether forms peroxy compound DUE to -O- grouphope this will help you

The units for atomic radii are PM, equal to 10 RAISED to −12 meters. As an EXAMPLE, the internuclear distance between the TWO hydrogen atoms in an H2 molecule is measured to be 74 pm.

the FUNCTION of dynamic equilibrium?ANS. Dynamic equilibrium is an example of a steady state function. For a SYSTEM in a steady state, presently observed behavior continues into the FUTURE. Therefore, once a reaction has reached equilibrium, the ratio of product and reactant concentrations will remain the same EVEN as the reaction continues.

Here's your ANSWER EXPLANATION:HIGH MELTING points.good CONDUCTORS of electricity.good conductors of heat.high density.malleable.

Here's your answer EXPLANATION:Hess' law states that the CHANGE of enthalpy in a CHEMICAL reaction (i.e. the heat of reaction at constant PRESSURE) is INDEPENDENT of the pathway between the initial and final states.

A COMPOUND that does not CONTAIN carbon is an INORGANIC compound as opposed to an organic compound, which contains carbon and hydrogen.please MARK as brainliest.

tion:According to the first law of THERMODYNAMICS, ENERGY can be TRANSFERRED from place to place or changed between different forms, but it cannot be created or DESTROYED. ... Humans can convert the CHEMICAL energy in food, like this ice cream cone, into kinetic energy by riding a bicycle.

Hess's law states that the energy CHANGE in an overall chemical REACTION is equal to the sum of the energy changes in the individual reactions COMPRISING it. ... The law is a variation of the FIRST law of thermodynamics and CONSERVATION of energy.

tion:The computer screen on which you are reading this article, the clothes that you are wearing, the food that you eat and even the cars in which you ride all have one thing in common. What is this thing? They all are comprised of some element of carbon. Actually, all organic things are made up of carbon. This is why the study of carbon and its components is so important.Carbon Uses in Everyday LifeGraphite can be used as the lead in pencils and is also used in steel production. Amorphous carbon can be used in making paints and inks and in batteries.More About CarbonThe origin of the name ‘carbon’ is a Latin WORD ‘carbo’ which means CHARCOAL. This may come as a surprise to you, but it is the fourth most abundant element in the entire universe. And it is the second most abundant element in our bodies, the first being oxygen. As a matter of fact, all organic substances in the world contain carbon in some form or element, which is why it is the base for the entire branch of organic chemistry.Carbon Atomimage in attachment The atomic number of carbon is 6, which represents the number of electrons. It is represented by the symbol C and is a non-metal. It has 6 protons, 6 neutrons and obviously 6 electrons. A carbon atom is considered to be special and unique because it can bond with other carbon atoms to an almost unlimited degree. It is because its atom is very small in size and can conveniently fit in as a part of larger molecules. Each of its atoms has four electrons in its outer shell called valence electrons and can form for CHEMICAL bonds with other atoms and molecules.Physical Properties of CarbonThe physical properties of this element vary according to its allotropes. The two major allotropes are diamond and graphite. These two have almost opposing physical properties.Whereas diamond is transparent and has no colour, graphite is opaque and blackDiamond is the hardest substance known to man, graphite is soft and spongy in textureNow diamond cannot conduct electricity at all, graphite is a very good conductor of electricityBoth allotropic elements are solid, non-gaseousAlso both diamond and graphite are insoluble in waterIt does not melt when heated, it sublimes which is it turns to gaseous formUses of Carbon in daily lifeNow you may not even notice but carbon is used in so many daily activities. Some of the most important uses are:It makes up for 18% of the human body. Sugar, glucose, proteins ETC are all made of it. The food we eat contains an important source of energy which we call carbohydrates. Carbohydrates are nothing but elements of carbon itself.Carbon in its diamond form is used in jewellery. But diamonds are also used for industrial purposes. It is the hardest substance known to man and so has many uses in manufacturing processes.Amorphous carbon is used to make inks and paints. It is also used in batteries.Graphite is used as the lead in your pencils. It is also used in the production of steel.One of the most important uses is carbon dating. We can actually use carbon to measure the age of things. Scientists use a rare form of carbon called Carbon-14 to measure the age of fossils, bones etc. The release of this carbon-14 is recorded to estimate the LIFE of the said organic substance. This is how scientists find the age and period of dinosaur bones and fossils!

1.00784 uExplanation:Find the relative mass of any atom by ADDING the number of PROTONS to the number of neutrons. Hydrogen has a relative ATOMIC mass of 1, and carbon-12 has a relative atomic mass of 12. Isotopes of the same element have different NUMBERS of neutrons, so you need to calculate for one specific isotope
