What is a type of nuclear reaction in which the nucleus of a heavy atom splits into two or more smaller nuclei that have masses of relatively similar size?

A: gamma radiation
B: nuclear fusion
C: chain reaction
D: nuclear fission

Answer:

2.85g/cm^3

Explanation:

density = mass/volume

density=8.76g/3.07cm^3= 2.85g/cm^3

Answer:

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

From the question we have

[tex]density = \frac{8.76}{3.07} \\ = 2.85342019...[/tex]

We have the final answer as

The answer is Reverse Itself In The Past

Answer:

Zero grams of NaCl & KNO₃  ... The reagents mixed in aqueous solution would not produce products as no driving force is present; i.e., no precipitate, weak electrolyte or gas decomposition product will form.

Explanation:

NaNO₃(aq) + KCl(aq) => (theoritically) NaCl(aq) + KNO₃(aq)

However all chloride salts from metathesis rxns remain soluble and 100% ionized except for halide derivatives of Hg⁺², Ag⁺ & Pb⁺₂.  Further, all NO₃⁻ salt derivatives also remain soluble and 100% ionized.

Technically, metathesis reactions (also known as double replacement rxns) depend upon the formation of a 'driving force' that leaves the reaction system in the form of a precipitate, weak electrolyte (weak acid or weak base) or a gas decomposition product. So, the reaction in this case should be as follows:

NaNO₃(aq) + KCl(aq) => No Reaction

Explanation:

The word ecosystem refers to the all of the living species as well as non-living elements in a particular environmental area. For instance, a lake, swamp, coral reef, forest, or a prairie would each be considered an ecosystem. Ecosystems can vary greatly in size and individual characteristics -- for instance, the ecosystem of a puddle differs greatly from that of a swath of tundra.  

Despite these disparities, all ecosystems function similarly in the way in which energy flows into, through, and out of them through the energy cycle

Energy is transferred into and out of ecosystems via a web of complex interactions. Energy enters an ecosystem from external sources and moves throughout its components. For instance, energy from the sun flows through plants, microorganisms, and animals. Energy cycles in an ecosystem end with decomposition, and then the process begins anew    

Essentially, the flow of energy through ecosystems can be explained by who eats what. Keep in mind, however, that energy transfer isn’t perfectly efficient; much of it dissipates as heat at various phases in the cycle.

The energy flows from the sun to the plants by photosynthesis and animal eats plants and energy is transferred from plants to animals.

The energy transfer isn't entirely efficient because a significant amount of it evaporates as heat at different points throughout the cycle.

Despite these differences of energy, all ecosystems function similarly in terms of the energy cycle, which governs how energy enters, passes through, and exits them.

Ecosystems receive and expend energy through a network of intricate interconnections. An ecosystem receives energy from outside sources, which circulates among its parts.

Thus, as a result of photosynthesis, energy is transmitted from the sun to plants, which are then consumed by animals.

Answer:

Percent yield of reaction is 75%.

Explanation:

Given data:

Moles of A = 2.0 mol

Moles of B = 4.0 mol

Moles of C formed = 1.8 mol

Percent yield of reaction = ?

Solution:

Chemical equation:

2A + 5B     →      3C +  D

We will compare the moles of A and B with C from balance chemical equation.

                A         :          C

                2         :           3

               B          :         C

                 5         :         3

                 4         :        3/5×4 = 2.4 mol

Number of moles of C formed by 4 moles B are less thus B is limiting reactant and will limit the yield of C.

Percent yield:

Percent yield =  actual yield /theoretical yield × 100

Percent yield = 1.8 mol / 2.4  × 100

Percent yield =75%

Answer: Polymers are broken down into monomers via hydrolysis reactions, in which a bond is broken, or lysed, by addition of a water molecule. ... This is the reverse of a dehydration synthesis reaction, and it releases a monomer that can be used in building a new polymer.

The explosion of fireworks is an example of chemical change. During a chemical change, substances are changed into different substances. In other words, the composition of the substance changes.

Answer:

The similarity is that Elements and Compunds exist in stable form because of the bonds formed between their atoms. The difference is that an element is a material that consists of a single type of atom and a compound consists of two or more types of elements held together by covalent or ionic bonds.

[tex]\boxed {\tt Carbohydrate \ or \ monosaccharides}[/tex]

Explanation:

There are 4 main types of macromolecules: lipids, proteins, carbohydrates, and nucleic acids.

If you are looking for some quick energy, the best choice is carbohydrates. Carbohydrates are the easiest for the body to break down and turn into ATP/energy.

There are also different types of carbohydrates. If you want a more specific answer, monosaccharides is the best answer. They are the simplest sugars. Also, glucose is a monosaccharide, and it shows up directly in the cellular respiration formula. If glucose is consumed, the body doesn't have to break it down before starting respiration.

Explanation:

The photosynthesis equation is:

energy+6CO₂+6H₂O--> C₆H₁₂O₆+6O₂

The reactants are light energy, carbon dioxide, and water. The products are glucose and oxygen.

The products of photosynthesis become the products of the light-independent reaction called cellular respiration, which creates useable energy. Therefore, the correct answer is oxygen and glucose.

Answer:

For, this question,

The balanced equation is; 2Al + 3 ----> 2Al

We can now, calculate how many grams of will be needed to completely convert 15 g of Al into Al.

Here, the reaction produces, 2 moles of Al

So, For 15.0 g of Al; we can calculate;

(15.0 g Al) X (1 mole Al / 26.98 g Al) X (3 moles / 2 moles Al) X (159.81 g / 1 mole )

= 133 g of  will be needed.

Therefore, 133g of will be needed to completely convert 15 g of Al into Al.

Answer:

Kc = 3.94

Explanation:

CH₃COOH(g) + C₂H₅OH(g) → CH₃COOC₂H₅(g) + H₂O(g)

Liquids aren't included in the equilibrium constant, but at 100°C, all four compounds are a gas.  So the equilibrium equation is:

Kc = [CH₃COOC₂H₅] [H₂O] / ([CH₃COOH] [C₂H₅OH])

Set up an ICE table for each row and calculate the value of Kc.  Then average the results.  (See picture.)

Kc ≈ (3.919 + 4.012 + 3.902) / 3

Kc ≈ 3.94
