formula for soda glass

Answer:

occur if two of the ions form an insoluble ionic compound, which precipitates out of solution

Explanation:

When two ionic compounds are dissolved in water, a double replacement reaction takes place if two of the ions form an insoluble ionic compound, which precipitates out of solution. In double displacement reaction ions switch partners. And hence, produce an insoluble precipitate.

Answer:

Total energy consumed = 1,882.8 joules

Explanation:

Given:

Calories burned = 450 calories

Find:

Total energy consumed

Computation:

1 calorie = 4.184 joules

So,

450 calories = 4.184 × 450

450 calories = 1,882.8 joules

Total energy consumed = 1,882.8 joules

Answer:

Inverse proportion occurs when one value increases and the other decreases. For example, more workers on a job would reduce the time to complete the task. They are inversely proportional.

Explanation:

Answer:

The atomic number of the atom is 14.

Explanation:

The following data were obtained from the question:

Valence electrons = 4

Atomic number =.?

From the question given, we were told that the valence electron is in the m shell. Thus, we can say:

M shell = 4 electrons

The number of shells of the atom can be written in the order K, L, M with M as the last shell because we were told that the valence electrons i.e electrons in the outer shell is located at the M shell.

From a detailed knowledge of atom,

K shell = 1st shell

L shell = 2nd shell

M shell = 3rd shell

The first shell, K of an atom can only accommodate 2 electrons while others can accommodate a maximum of 8 electrons.

Note: we can only put electrons in another shell if a shell is already having 8 electrons. This rule only applies to the 2nd shell and above.

Thus, the atom in question has the following electrons:

K shell = 1st shell = 2 electrons

L shell = 2nd shell = 8 electrons

M shell = 3rd shell = 4 electrons

To get the atomic number of the atoms, we simply add all the electrons together.

This is illustrated below:

Atomic number = 2 + 8 + 4

Atomic number = 14

Therefore, the atomic number of the atom is 14.

For example, in a molecule of aspirin, C9H8O4, there are 9 carbon atoms, 8 hydrogen atoms and 4 oxygen atoms. compound.

Explanation:

The carbon atoms are in 0.650 gram tablet of aspirin (C9H8O4) is 3.24 x 10² atoms.

Atoms are defined as the smallest unit of matter that can be divided without releasing electrically charged particles.

After the Big Bang, the building blocks of matter were generated is known as atoms.

Molar mass of aspirin = 180.2 g

Number of carbon atoms

= 0.650 g x 1 mole aspirin / 180.2 g x 9 / 1 mole aspirin

= 3.24 x 10² atoms

Thus, the carbon atoms are in 0.650 gram tablet of aspirin (C9H8O4) is 3.24 x 10² atoms.

Explanation:

Structural formulas of polymers show the actual arrangement of atoms within the polymer. This helps us to explain some of the observed properties of the polymer.

A polymer is composed of monomers. Monomers are small molecules which could link together to form a larger molecule.

There are three kinds of formulas that could be used to represent a chemical substance;

Compounds used as medicines are most often organic compounds, which are often divided into the broad classes of small organic molecules (e.g., atorvastatin, fluticasone, clopidogrel) and "biologics" (infliximab, erythropoietin, insulin glargine), the latter of which are most often medicinal preparations of proteins

Answer:

NO3 that is the answer to the question

Answer:

20 mL

Explanation:

The student should record 20 mL as the correct volume.

The curved surface of a liquid that is usually observed in a buret is referred to as the meniscus. This meniscus is created as a result of the surface tension of the liquid against the walls of the buret. Hence, in order to avoid errors due to parallax, the bottom of the meniscus should be read and not the top.

Therefore, the correct volume that the student should record is 20 mL.

A saturated solution is at equilibrium (rate of dissolution is equal to rate of crystallization) with some equilibrium constant K1. If you change the temperature of the system at equilibrium, you will observe a different equilibrium constant K2. Whether the equilibrium constant increase or decreases is described by the Van't Hoff equation:

ln(K2K1)=−ΔHR(1T2−1T1)

So it depends on the sign of the enthalpy of reaction, in this case the enthalpy of dissolution.

Answer:

B) is any species that donates a proton.

Answer:

A Brønsted-Lowry acid is any substance (molecule or ion) that can donate a hydrogen ion (H+).

A Brønsted-Lowry base is any species that can accept a hydrogen ion (H+).

Explanation:

In short, acids have the ability to donate protons and bases have the ability to accept protons.

Take the following reaction for example:

H2SO4+NH3⇌NH+4+HSO−4

Sulfuric acid (H2SO4) is the Brønsted-Lowry acid because it donates a hydrogen ion. Ammonia (NH3) is the Brønsted-Lowry base because it accepts the hydrogen ion.

The Brønsted-Lowry theory also introduces the concept of conjugate acid-base pairs. A conjugate acid-base pair are two species that differ by a (H+) ion.

Based on the reaction above, the ammonium ion

(NH+4) is the conjugate acid of the base ammonia and the hydrogen sulfate ion (HSO−4) is the conjugate base of sulfuric acid.

Here's a tip to let you know which substance is the conjugate acid and which substance is the conjugate base:

A conjugate base has one less (H+) proton than the acid you started with.

A conjugate acid has one more (H+) proton than the base you started with.

So option c is correct
