1. According to Rutherford and soddy's law of Beta emission:

${K}^{42} \: ---> {Ca}^{40} + {2e}^{0}$

3. According to Rutherford and soddy's law of Alpha emission:

${U}^{238} \: ---> {Th}^{234} + {He}^{4}$

4. The process in which two or more light nuclei are combined to form a single nucleus with the release of tremendous amount of energy is called a nuclear fusion. The inner core of Sun is at very high temperature and is suitable for fusion. In fact the source of energy of Sun and other stars is nuclear fusion reactions.

They called it the Tariff of Abomination aka the Tariff of Evil because it really hurt the south. Any tariffs hurt the South with their agricultural business so I guess they believed it would lead to losing their jobs, etc..

Based on solubility rules what ions in water might interfere with the analysis of calcium ions by precipitation of calcium carbo

Pavlova-9 [17]

First, we must know what happens in the precipitation reaction. This type of reaction is a double replacement reactions. It is consists of two reactant compounds which interchange cations and anions to form two products. One of the products is an insoluble solid called a precipitate. For the precipitation of CaCO₃, there are two consecutive reactions involved:

1. Slaking of quicklime, CaO
CaO + H₂O ⇒ Ca(OH)₂

2. Precipitation
Ca(OH)₂ + CO₂ ⇒ CaCO₃ + H₂O

The ions that make up the H₂O molecule are H⁺ and OH⁻. According to solubility rules, the cation (positively charged ion) is likely to be attracted to an anion (negatively charged ion). Together, they form an ionic bond. This type of bond is when there is a complete transfer of electrons between the two. The Ca²⁺ cation lacks 2 electrons, while the anion OH⁻ has an excess 1 electron. In order to be stable, 1 Ca²⁺ ion and 2 OH⁻ ions must combine.

Therefore, the answer is OH⁻ ion.

Alright, now you actually have an aqueous solution of your salt! Though perhaps not all of the salt has dissolved yet, but we'll

erica [24]

If not all of the salt has dissolved then the measurement of the concentration at the time is really inaccurate.

<h3>What is concentration?</h3>

The concentration is the amount of substance that is present in solution. We know that we can not measure the concentration unless all of the solute have been dissolved in the solution.

Thus, if not all of the salt has dissolved then the measurement of the concentration at the time is really inaccurate.

Which is the balanced single displacement reaction between Aluminum (Al3+) and Copper Sulfate (Cu2+(SO4)2-)

Aliun [14]

Answer:

The balanced single displacement reaction between aluminum and copper sulphate is as follows.

$2Al(s)+3CuSO_{4}(aq)\rightarrow Al_{2}(SO_{4})_{3}(aq)+3Cu(s)$

Explanation:

The given ions are as follows.

$Al^{3+}$ - Aluminium ion and copper sulfate ion.

Single displacement reaction occurs one element replaces another element.

Hence, the balanced chemical reaction is as follows.

$2Al(s)+3CuSO_{4}(aq)\rightarrow Al_{2}(SO_{4})_{3}(aq)+3Cu(s)$

<u>Oxidation half reaction:</u>

$Al\rightarrow Al^{3+}+3e^{-}$

Aluminium loses three electrons.

<u>Reduction half reaction:</u>

<u> $Cu^{2+}+2e^{-}\rightarrow Cu(s)$ </u>

Copper gain three electrons.

What do enzymes do to chemical reactions in cells?

romanna [79]

Answer:

Enzymes are homogenous, thermolabile,biological catalyst that increases the reaction rate of a chemical reaction.

Explanation:

Enzymes are used as catalyst in many biochemical reactions.Enzymes basically interact in a complementary fashion with the transition state of the reaction thus helping to decrease the energy barrier called activation energy.Thus enzymes helps to stimulate the velocity of biochemical reaction.

It is very important point to note that enzymes do not affect the reaction equilibrium.
