Calcium carbonate contains the carbonate ion. Citric acid is an acid. When an acid reacts with a carbonate, carbon dioxide gas is one of the products. Carbon dioxide gas produces the fizzing effect in water.

When an acid reacts with a carbonate, carbon dioxide gas is one of the products.

If antacids are dissolved prior to ingestion, the reaction between carbonate and hydrogen is faster.

A column is filled with four different liquids of different densities. A red liquid, a blue liquid, a green liquid, and a purple

Svet_ta [14]

Answer:

The order of liquid from top to bottom is as follow

Purple, green, red, blue

Explanation:

Chart of densities:

Red = 1.2 g/cm∧3
Blue = 1.6 g/cm∧3
green = 0.8 g/cm∧3
Purple = 0.1 g/cm∧3

Density:

Density is the ratio of mass and volume as follow

d = m/v

Summary:

Greater the density, it will be at bottom and vice versa.
Blue liquid has greater density so it will be at bottom
Purple liquid has low density, so it will be at top.

How many possible stereoisomers are there of propylene glycol, an organic compound found in clearasil acne cream, caladryl, colg

vova2212 [387]

Answer:

Explanation:

Isomers are molecules with the same molecular formula, but with some difference. If that difference is in the manner the atoms are distributed in the molecule, they are called structural isomers; if the difference is the way the molecule is in space, they're called space isomers (cis/trans); and there are the stereoisomers, which the molecules are images that can be overlapping.

The stereoisomers have the property to deviate the polarized light, and, when a molecule has a chiral carbon, it means that it has stereoisomers. The number of stereoisomers is 2ⁿ, where n is the number of chiral carbons.

Chiral carbon is a carbon that bonds with four different structures. So, below is represented the molecule of propylene glycol, and it has only one chiral carbon (see the blue arrow), so, it has only 2 stereoisomers.

Which of the following describes the electron sharing between hydrogen and fluorine?

EastWind [94]

Hello
We know both the elements involved in bonding are non-metals and the primary type of bonds involved in non-metals are covalent bonds. Covalent bonds are formed when two atoms share one or more electrons; thus we know that whatever the number of electrons shared, it has to be equal for both. We can eliminate choices A and B.
Next, we understand that it is easier for one atom to be shared among the two, rather than the 7. First, because Hydrogen needs only 1 electron to be stable and would require energy to compensate the remaining 6. Second, electrons are attracted towards the nucleus so it is inefficient to try and share 7 electrons when 1 provides the same amount of stability to Fluorine.
Therefore, the answer is C.

All of the following reactions can be described as displacement reactions except:____________.

Lady_Fox [76]

Answer:

Explanation:

The reaction that is not a displacement reaction from all the options is $C_6H_6_{(l)} + Cl_{2(g)} --> C_6H_5Cl_{(l)} + HCl_{(g)}$

In a displacement reaction, a part of one of the reactants is replaced by another reactant. In single displacement reactions, one of the reactants completely displaces and replaces part of another reactant. In double displacement reaction, cations and anions in the reactants switch partners to form products.

Options a, c, d, and e involves the displacement of a part of one of the reactants by another reactant while option b does not.

Correct option = b.
