trasher [3.6K]2 years ago
6 0

Answer:

A colloid is a heterogeneous mixture in which the dispersed particles are intermediate in size between those of a solution and a suspension. The particles are spread evenly throughout the dispersion medium, which can be a solid, liquid, or gas.

In the chemical reaction below, calcium (Ca) and water (H2O) react to form calcium hydroxide (Ca(OH)2) and hydrogen gas (H2). Ca
lakkis [162]

Answer:

C.

Explanation:

The mass of the reactants should not change, in fact it would be equal because the only thing that changes is the form in which your products are in. The reactants will still have the same amount of mass from the products as no products were removed or added, the structure changed, the mass did not.

A group of students working in a high school chemistry lab believe they have discovered a new element! How exciting? Upon furthe
spayn [35]

Answer:

Explanation:

Information given about the element:

Number of protons = 74

Number of neutrons = 110

For the atomic number:

Neutral atoms such as this one would have their atomic number to be the same with their number of electrons and protons:

     atomic number = number of protons = number of electrons

The atomic number would therefore be 74

For the mass number:

The mass of an atom is centrally concentrated within the tiny nucleus. The mass number is the sum of protons and neutrons in an atom. Protons and neutrons are nuclear particles and are called nucleons:

     Mass number = number of protons + number of neutrons = 74+110=184

Is this a new element?

From the peroidic table, tungsten(W) perfectly fits this description of the atom. It has an atomic number of 74 and a mass number of approximately 184. The element is not a new element.

Is it solid, liquid, or gas?

The element is a hard metallic solid. It is a classified as a transition metal on the periodic table. Transition metals have very unique metals and are mostly solids.

The orbital shape, i.e. the radial probability distribution, of the 2s sublevel shows it to be more stable than that of the 2p s
olga_2 [115]

The orbital shape, i.e. the radial probability distribution, of the 2s sublevel shows it to be more stable than that of the 2p sublevel because it closer to The nucleus.

The nucleus of an atom consists of neutrons and protons, which in flip are the manifestation of more primary debris, known as quarks, which are held in affiliation through the nuclear sturdy pressure in positive solid combos of hadrons, referred to as baryons.

The nucleus of the atom, also called the atomic nucleus, is the small, dense, spherical center of an atom. The nucleus incorporates  subatomic debris: the protons and the neutrons. Protons are definitely charged particles with a mass of about 1 amu (atomic mass unit).

It is composed of protons, which have a fantastic charge, and neutrons, which haven't any price. Protons, neutrons, and the electrons surrounding them are lengthy-lived particles found in all ordinary, clearly going on atoms.

30g of naoh is dissolved in 1.5 liter solution the active mass of naoh is?
Pepsi [2]

Answer:

0.5mol/L

Explanation:

First, let us calculate the number of mole NaOH = 23 + 16 + 1 = 40g/mol

Mass of NaOH from the question = 30g

Number of mole = Mass /Molar Mass

Number of mole = 30/40 = 0.75mol

Volume = 1.5L

Active mass = mole/Volume

Active mass = 0.75mol/1.5L

Active mass = 0.5mol/L

Calculate the molarity of glucose in a solution that which contains 35 g of glucose in 0.16 kg of phenol
sleet_krkn [62]
C(Molarity) = n of solute/V of solution (mol/L)

glucose(C6H12O6) = 180g/mol
glucose 35g = 35g/(180g/mol) = 0.1944mol

We need density of solution here, and I assume it as density of phenol, 1.07g/mL. (I don't know why the question doesn't contain it)

phenol 0.16kg = 0.16kg/(1.07kg/L) = 0.1495L

0.1944mol/0.1495L = 1.300M(mol/L)
