What do cations and anions form?

1 answer:

7 0

Answer: Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride.

What is molar concept

andrew11 [14]

Answer:

The molar mass of a substance is defined as the mass in grams of 1 mole of that substance. One mole of isotopically pure carbon-12 has a mass of 12 g. ... That is, the molar mass of a substance is the mass (in grams per mole) of 6.022 × 1023 atoms, molecules, or formula units of that substance.

dmitriy555 [2]

Saturated Solution: A solution with solute that dissolves until it is unable to dissolve anymore, leaving the undissolved substances at the bottom. Unsaturated Solution: A solution ( with less solute than the saturated solution )that completely dissolves, leaving no remaining substances. Supersaturated Solution.

The mechanisms of most common reactions consist of two or more elementary steps, each of which describes a single molecular even

olga2289 [7]

Answer:

The correct answer is "True".

Explanation:

A reaction mechanism is a theoretical postulate that tries to explain in a logical way which are the elemental and intermediary reactions that happen in a chemical reaction and that allow to explain the qualitative and quantitative characteristics observed in its development, in which a unique molecular event is described in each elemental step.

Lead has a density of 11.4 g/cm^3. What is the density in kilograms per cubic meter?

Vikentia [17]

The density in kg/m³ = 1.14 x 10⁴

<h3>Further explanation </h3>

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of density

The unit of density can be expressed in g/cm³ or kg/m³

Density formula:

$\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}$

ρ = density , g/cm³ or kg/m³

m = mass , g or kg

v = volume , cm³ or m³

A density of Lead : ρ = 11.4 g/cm³

the density in kg/m³ :

$\tt 11.4~\dfrac{g}{cm^3}\times \dfrac{kg}{10^3~g}\times \dfrac{cm^3}{10^{-6}~m^3}=\boxed{\bold{1.14\times 10^4~\dfrac{kg}{m^3}}}$

HELP ASAP!!!!!! I NEED HELP

Whitepunk [10]

The organs of the digestive system such as the pancreas, liver, stomach, small intestine, and large intestine help in the digestion of food.

<h3>What are organs?</h3>

Organs are a collection of tissues that are closely related and which perform a related function.

The role and function of the organs of the digestive system are as follows:

Pancreas - produces pancreatic juice which contain digestive enzymes
Liver - produces bile for the emulsification of fat
Stomach - serves as a temporary store of food and produces digestive juices
Small intestine - functions in food digestion
Large Intestine - helps to remove undigested food from the body

Therefore, the organs of the digestive system such as the pancreas, liver, stomach, small intestine, and large intestine help in the digestion of food.
