What determines the identity of the salt that forms in a neutralization reaction?

What happens to a Lithium atom for it to become an Li+1 ion?

Maru [420]

Answer:

If an atom gains or loses an electron, it bacomes an ion. An atom that gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion

Explanation:

A lithium atom has 3 protons and 3 electrons. It can lose one of its electrons, making it an ion. It now has more positive protons than electrons so it has an overall positive charge. Therefore it is a positive ion.

A fluorine atom will tend to gain, rather than lose, an electron. By gaining a negative electron, it has an overall negative charge. It has become a negative ion.

A student observes that a popcorn kernel has a hard coat. He places the kernel in a moist paper towel and observes it for severa

Ierofanga [76]

Answer: Water inside the seed coat creating a pushing force, breaking the seed coat.

Explanation:

Seed germination can be defined as the process by which a new plant emerge out from a seed. The radicle is the first emerging part from a seed and it develops into a root and the plumule is the second emerging part and it develops into a shoot. The light, water, adequate temperature, and soil are the factors that are necessary for seed germination.

According to a given situation, the popcorn kernel will receive the moisture necessary for the germination process, the water will imbibe into the seed coat creating pressure inside the seed and which will cause the seed coat to break and the new plant parts or seedling will emerge out of the seed coat.

If 0.025 gram of Pb(NO3)2 is dissolved in 100. grams of H2O, what is the concentration of the resulting solution, in parts per m

anastassius [24]

Answer:

249.94ppm

Explanation:

Given parameters:

Mass of Pb(NO₃)₂ = 0.025g

Mass of water = 100g

Unknown:

Concentration of solution in ppm = ?

Solution:

Concentration in parts per million gives the amount of solute found in a million units of the solution. They are desirable for expressing very small amount of solutes in a large solution. For example, the level of arsenic in the soil.

Concentration in ppm = $\frac{amount of solute}{amount of solution} x 10^{6}$

A solution is made up of solute and solvent. The solvent here is water.

mass of solution = mass of solute + mass of solvent = 0.025 + 100 = 100.025g

Concentration in ppm = $\frac{0.025}{100.025} x 10^{6}$ = 249.94ppm

In tne equation below identify the bronsted lowry acid bronsted lowry base conjugate acid conjugate base

Ad libitum [116K]

Answer:

Brønsted-Lowry acid: HNO₂

Brønsted-Lowry base: NH₃

Conjugate acid: NH₄⁺

Conjugate base: NO₂⁻

Explanation:

The equation is:

$HNO_2(aq)+NH_3(aq)\rightarrow NH4^+(aq) + NO2^-(aq)$

Brønsted-Lowry acids are H⁺ donors.

Brønsted-Lowry bases are H⁺ acceptors.

Thus, on the left side, HNO₂ is the acid and NH₃ is the base.

The conjugate acids and conjugate bases are on the right side of the equation.

The conjugate acid is the spieces that is formed after a base accepts the proton; thus it is NH₄⁺. A conjugate acid contains one more H atom and one more + charge than the base that formed it.

The conjugate base is the species that is formed after the acid donates its proton; thus, NO₂⁻ is the conjugate base. A conjugate base contains one less H atom and one more - charge than the acid that formed it.

Summarizing:

Brønsted-Lowry acid: HNO₂

Brønsted-Lowry base: NH₃

Conjugate acid: NH₄⁺

Conjugate base: NO₂⁻
