7 0

Answer:

Yes

Explanation:

Nuclear equation:

²¹⁴₈₂Pb →  ₂He⁴ + ²¹⁰₈₀Hg

The given equation is balanced. It shows the emission of alpha particle which is helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number less than 4  and atomic number less than 2 as compared to parent atom the starting atom.

Properties of alpha radiation:

Alpha radiations are emitted as a result of radioactive decay. The atom emit the alpha particles consist of two proton and two neutrons. Which is also called helium nuclei.

Alpha radiations can travel in a short distance.

These radiations can not penetrate into the skin or clothes.

These radiations can be harmful for the human if these are inhaled.

These radiations can be stopped by a piece of paper.

₉₂U²³⁸   →   ₉₀Th²³⁴  + ₂He⁴  + energy

Which of the following is not an acid-base neutralization reaction?
Alexus [3.1K]
A neutralization process is a reaction between an acid and a base which yields a salt and water. From the choices, a neutralization reaction would be: 2 HBr + Ca(OH)2 yields CaBr2 + 2 H2O.  Moreover, <span>NH3 + HCl yields NH4Cl is also a neutralization reaction. The complete reaction is actually NH4OH + HCl --> NH4Cl + H2O. NH4OH is the aqueous solution of NH3. This reaction is still a neutralization reaction.

On the other hand, the reaction </span><span>HCl + HBr yields H2 + ClBr is not valid. There is no reaction between HCl and HBr because both are strong acids. They would just dissociate into ions like H+, Cl- and Br-.

The valid reaction that is clearly not a neutralization process is </span><span>H2 + Br2 yields 2 HBr. This is a combination reaction yielding a strong acid HBr.</span>

Enter the net ionic equation, including phases, for the reaction of AgNO3 ( aq ) and KCl ( aq ) . Refer to the solubility rules
GrogVix [38]

Answer:

First, it is easiest if you write the compete molecular equation:

AgNO3(aq) + KCl(aq) ==> AgCl(s) + KNO3(aq) ..  molecular equation.

You must also know or look up which compounds are soluble (aq) and which are not (s). In this case, silver chloride (AgCl) is not soluble.  Thus, the net ionic equation is...

Ag+(aq) + Cl-(aq) ==> AgCl(s)

If an experiment produces 5 g but should have made 500 g, what is the percent<br> yield?
hoa [83]

Answer:

Percentage of yield = 1%

Explanation:

Given:

Amount of yield = 5g

Total amount of product = 500 gram

Find:

Percentage of yield = ?

Computation:

⇒ Percentage of yield = [Amount of yield / Total amount of product]100

⇒ Percentage of yield = [5g / 500g]100

⇒ Percentage of yield = [0.01]100

⇒ Percentage of yield = 1%
