Salt=compound, soda=liquid solution, aluminum foil=element, milk=colloid,
steel=solid solution
vaieri [72.5K]3 years ago

Answer:

liquid solution: soda

solid solution: stell.

compound: salt.

coloid: milk.

element: aluminum foil.

Explanation:

Solutions are homogeneous combination of two components, a solute (the one in lower proportion) and a solvent (the one in bigger proportion). Soda is solution composed by water (solvent) and carbonic acid (solute). Steel is a solid combination of Iron (solvent) and Carbon (solute).

A compound is a molecule composed by 2 or more different elements. Here, salt (NaCl) is composed by Sodium (Na) and Chlorine (Cl).

Coloids are systems, apparently homogeneous, but when you look deeper you can detect different phases. This is the case of milk which is a fluid with proteins and differents components constituting different phases.

Finally an element is a form of materia in which there is only one atom. Aluminum foil is an example of this.

What two elements in the sun mostly made of
ivanzaharov [21]

The sun is made up of two main elements, hydrogen and helium.

  • Hydrogen makes up about 92% of all of the atoms in the sun while helium makes up about 7.8%.
  • Oxygen, carbon, neon and nitrogen make up most of the remaining 0.2%.

In a high-mass star, hydrogen fusion occurs via the choose one: a. spin-spin interaction. b. proton-proton chain. c. cno cycle.
Lerok [7]

In a high-mass star, hydrogen fusion occurs via the CNO (Carbon-Nitrogen-Oxygen) cycle.

According to the life cycle of a star, there are three main phases in the life of a star: The initial phase (a quick phase), short phase or supergiant phase and death phase or supernova explosion.

the CNO cycle means Carbon-Nitrogen-Oxygen cycle and this process tale place during main sequence phase.

In this phase, hydrogen fuses into helium as a result of six different reaction taking place inside a star.

The first step of the sequence begins when the nucleus of carbon 12 isotope emits gamma rays after capturing a proton and produces nitrogen-13.

This whole cycle is known as stellar nucleosynthesis.

Calculate the mass of CaCl2•2H2O required to make 100.0 mL of a 0.100 M solution. Each of the calculations below will take you t
Zolol [24]

Answer:

The mass is 1.4701 grams and the moles is 0.01.

Explanation:

Based on the given question, the volume of the solution is 100 ml or 0.1 L and the molarity of the solution is 0.100 M. The moles of the solute (in the given case calcium chloride dihydride (CaCl2. H2O) can be determined by using the formula,  

Molarity = moles of solute/volume of solution in liters

Now putting the values we get,  

0.100 = moles of solute/0.1000

Moles of solute = 0.100 * 0.1000

= 0.01 moles

The mass of CaCl2.2H2O can be determined by using the formula,  

Moles = mass/molar mass

The molar mass of CaCl2.2H2O is 147.01 gram per mole. Now putting the values we get,  

0.01 = mass / 147.01

Mass = 147.01 * 0.01

= 1.4701 grams.
