The nucleus of a radium-226 atom is unstable, which causes the nucleus to spontaneously(1) absorb electrons (3) decay
(2) absorb protons (4) oxidize

Answers

Answer: The nucleus of radium-226 is unstable and hence undergoes decay.

Explanation: Radium has many isotopes. One of them is $_(88)^(226)\textrm{Ra}$ which has 88 protons and 138 neutrons. It is a radioactive isotope and undergoes decay process.

This isotope undergoes alpha - decay and produces Radon-222 isotope.

Equation for alpha - decay follows:

$_(88)^(226)\textrm{Ra}\rightarrow _(86)^(222)\textrm{Rn}+_2^4\alpha$

Hence, the nucleus of radium-226 undergoes decay process.

The answer is (3) decay. An atom whose nucleus is unstable is said to be "radioactive," and its nucleus undergoes nuclear decay.

Which of the following alcohols is dehydrated most easily with conc. H²SO⁴? a. p-O²NC⁶H⁴CH(OH)CH³ b. p-C1C⁶H⁴CH(OH)CH³ c. p-CH³OC⁶H⁴CH(OH)CH³ d. C³H⁵CH(OH)CH³

Answers

Answer:

a. p-o²nc⁶h⁴ch(oh)ch

Explanation:

Final answer:

The alcohol that is dehydrated most easily with conc. H₂SO₄ is p-C1C₆H₄CH(OH)CH₃.

Explanation:

The alcohol that is dehydrated most easily with conc. H²SO⁴ is p-C1C⁶H⁴CH(OH)CH³. This alcohol is tertiary, meaning it has three alkyl groups attached to the carbon atom containing the hydroxyl group. Tertiary alcohols are more easily dehydrated compared to primary and secondary alcohols because the carbon atom attached to the hydroxyl group is more stable due to the presence of the alkyl groups.

When wood is burned, energy is released in the forms of heat and light. Describe the reaction, and explain why this change does not violate the law of conservation of energy. Use the terms combustion, exothermic, and chemical energy.

Answers

Burning wood would be a sort of combustion (spontaneous), which is a biochemical process that occurs involving chemical energies.

It's indeed exothermic, which means it generates heat because it happens. Whenever the hardwood is burnt, charcoal decomposes and then becomes responsible for the formation and creates a new particle.
Because the carbons aren't generated but just redistributed or shuffled, this doesn't contradict the principle or the concept of conserving energy.

Thus the above approach is appropriate.

Burning wood is a form of spontaneous combustion, a type of chemical reaction occurring with chemical energy. It is exothermic, meaning it releases heat when it occurs.When wood is burned, carbon breaks down (which creates the crackling sound you hear) and creates a new material. Since the carbons are not being created and only rearranged, this does not violate the law of conservation of energy.

n=3mol+3mol

n=6mol

T=120+273=393K

P=nRT/V

P=6×0.0821×393/1

P=193atm

Which of these reactions can be classified as double replacement reactions?A) Zn + 2HCl → ZnCl2 + H2

B) 2NaCl + F2 → 2NaF + Cl2

C) 2AlBr3 + 3K2SO4 → 6KBr + Al2(SO4)3

D) 2K + MgBr2 → 2KBr + Mg

Answers

C is the answer. Reasons being that, two elements from both side of the reactant switches side to form two new compounds. On the other hand, A , B and D involves one element displacing the other to produce a new compound.

Answer:

The correct answer is option C.

Explanation:

Double displacement reaction is defined as the reaction in which exchange of ions takes place to give a product.

$AB+CD\rightarrow CB+AD$

Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction.

$AB+C\rightarrow CB+A$
