Answer:

A very large amount of energy is produced from a series of chemical reactions.

Explanation:

Nuclear fission is the process of splitting apart nuclei (usually large nuclei). When large nuclei, such as uranium-235, fissions, energy is released. So much energy is released that there is a measurable decrease in mass, from the mass-energy equivalence. This means that some of the mass is converted to energy.

Answer:

2nd option

Explanation:

Nuclear fission is the process of splitting apart nuclei (usually large nuclei). When large nuclei, such as uranium-235, fissions, energy is released. So much energy is released that there is a measurable decrease in mass, from the mass-energy equivalence. This means that some of the mass is converted to energy.

Salutations!

<span>___ Particles of which of the following have the greatest thermal energy

Gas is the particle that has the greatest thermal energy. Gas has the greatest thermal energy because the movement between particles is clump. This thermal energy is then converted into kinetic energy.

Thus, your answer is option C.

How many moles are there in 270.4 g sample of NaOH
pochemuha

Answer:

6.5

Explanation:

No of moles is the ratio of reacting mass to molar mass

RM - 270.4g

MM - 23+16+1= 40g/mol

270.4/40= 6.76mol

What is the mass, in grams, of each elemental sample? a. 2.3 * 10-3 molSb b. 0.0355 mol Ba c. 43.9 mol Xe d. 1.3 mol W
belka [17]

Answer:

a. Sb =0.280048 g ,  b. Ba=4.875215 g ,  c.  Xe=5763.631 g ,    d. W=238.992 g

Explanation:

number of moles = \frac{mass}{molar mass}

(a) For Sb, molar mass =121.76g/mol

number of moles =2.3*10^{-3}mol

<em>mass= number of moles * molar mass</em>

mass =2.3*10^{-3} *121.76

mass =0.280048 g

(b) for Ba, molar mass=137.33 g/mol

number of moles =0.0355 mol

mass = 0.0355 *137.33

mas = 4.875215 g

(c) for Xe, molar mass = 131.29 g/mol

number of moles =43.9 mol

mass =43.9 *131.29

mass =5763.631 g

(d) for W, molar mass = 183.84 g/mol

number of moles = 1.3mol

mass = 1.3 *183.84

mass = 238.992 g

You've collected several samples of DNA at a crime scene, but they are all short strands. What technique would you rely on to as
Nezavi [6.7K]

Option C

PCR technique would you rely on to assist with analysis

<u>Explanation:</u>

Experts elaborate this tiny specimen by a means acknowledged as a polymerase chain reaction, or PCR. PCR produces replicas of the DNA significant like DNA duplicates itself in a cell, offering virtually any coveted measure of the ancestral element.

Following the accumulation of biological matter from a crime picture, the DNA is beginning derived from its biological source element and then estimated to assess the number of DNA rescued. Subsequent detaching the DNA from its cells, precise areas are imitated with a procedure acknowledged as the polymerase chain reaction, or PCR.
