¿Cuántos gramos de dicloruro de manganeso se obtienen cuando reaccionan 7,5 g de ácido clorhídrico? MnO2 + 4 HCl = Mn Cl2 + Cl2 + 2 H2O *

Answers

Answer:

6.6 g

Explanation:

La ecuación de la reacción es;

MnO2 + 4 HCl -------> MnCl2 + Cl2 + 2H2O

Número de moles de HCl que reaccionan = 7.5g / 36.5 g / mol = 0.21 moles

Dado que;

4 moles de HCl producen 1 mol de MnCl2

0,21 moles de HCl producen 0,21 * 1/4 = 0,0525 moles de MnCl2.

Masa de MnCl2 = 125,844 g / mol * 0,0525 moles = 6.6 g

Analyzing models compare an atom’s structure to a ladder. Identify one way in which ladder is not a good model from the atom.

Answers

Answer:

Climbing a ladder assumes that you would touch/use each step only once. Electrons will take one layer that is empty first, and previous layers or "steps" will continue being filled with additional electrons only when every other layer is occupied by, at least, one electron.

determine the velocity of a cart traveling at 135cm in 5.5s.
​

Answers

velocity = distance/time

distance = 135cm
time = 5.5 s

velocity = 135 cm/5.5 s
velocity = 24.546 cm/s

Answer: 0.245 m/s

Explanation:

So velocity = d/t or distance over time in this case m/s or meters per second. But BE CAREFUL you must remember to convert cm to m always so 135 cm= 1.35m and 1.35m/5.5s= 0.245m/s

What happened during the fusion reaction shown?

Answers

Answer:

the answer to this question B. Two H nuclei that fused into one He necleus

Explanation:

Two hydrogen atoms fused to one helium molecule, hence option B is correct.

What is fusion?

Fusion is defined as a process in which two or more atomic nuclei unite to create new atomic and subatomic particles. Heat, which is produced when two atoms fuse, is the key to generating energy. Similar to how nuclear fission produces energy, this heat can be utilized to warm water, produce steam, and turn turbines to produce electricity.

In the core of the Sun, hydrogen is being converted to helium. This phenomenon is known as nuclear fusion. Fusion is what powers both the sun and the stars. One example of this kind of reaction is when two hydrogen atoms combine to form a helium atom. During the process, a portion of the hydrogen's mass is converted into energy.

Thus, two hydrogen atoms fused to one helium molecule, hence option B is correct.

What is the molarity of a solution made by diluting 0.025L of 6.0 M HCl until
the final volume of the solution is 1.75 L?

Answers

Answer:

Explanation:

Use the dilution equation: M1V1 = M2V2

M1 = 6.0 M

V1 = 0.025 L

M2 = ?

V2 = 1.75 L

(6.0 M)(0.025 L) = M2(1.75 L)

Solve for M2 --> M2 = 0.086 M HCl

Why does a DNA fingerprint require millions of copies of each DNA fragment

Answers

Answer:

Because it can identify a person.

DNA Fingerprint

A DNA fingerprint is a piece of DNA so distinct that it can prove a person's identity. These distinct areas can take on many different forms, but each form is unique to any one individual.

PCR allows the amplification of a single copy of DNA into millions of copies. However this technique requires that the DNA of interest already be of a known sequence in order to design primers that will specifically hybridize to the target DNA.

It is important as:

It's used as evidence in courts, to identify bodies, track down blood relatives, and to look for cures for disease.
