Answer:
0
Explanation:
they cancel each other out (ex: 1 positive and 1 negative cancels, making it neutral or a charge of 0)
HC₂H₃O₂ , equilibrium can be represented as:
HC₂H₃O₂ + H₂O--------->CH₃COO⁻ + H₃O⁺
HC₂H₃O₂, that is acetic acid dissociate in water that is H₂O and formed acetate anion that is CH₃COO⁻ and hydronium ions that is H₃O⁺.
Its equiibrium constant can be represented as:
Ka=\frac{[CH_{3}COO^{-1}]\times [H_{3}O^{+1}]}{CH_{3}COOH}
While NaC₂H₃O₂ can be dissociate as:
NaC₂H₃O₂------>CH₃COO⁻ + Na⁺
Sodium acetate that is NaC₂H₃O₂, dissociates as forming acetate anion and sodium cation.
Answer:
Methane + Bromine = (CH4+Br2)
Explanation:
When a mixture of methane and bromine is exposed to ultraviolet light - typically sunlight - a substitution reaction occurs and the organic product is bromomethane. However, the reaction doesn't stop there, and all the hydrogens in the methane can in turn be replaced by bromine atoms. The reaction is a single-step reaction.
This hypothetical process would produce actinium-230.
<h3>Explanation</h3>
An alpha decay reduces the atomic number of a nucleus by two and its mass number by four.
There are two types of beta decay: beta minus β⁻ and beta plus β⁺.
The mass number of a nucleus <em>stays the same</em> in either process. In β⁻ decay, the atomic number <em>increases </em>by one. An electron e⁻ is produced. In β⁺ decay, the atomic number <em>decreases </em>by one. A positron e⁺ is produced. Positrons are antiparticles of electrons.
β⁻ are more common than β⁺ in decays involving uranium. Assuming that the "beta decay" here refers to β⁻ decay.
Gamma decays do not influence the atomic or mass number of a nucleus.
Uranium has an atomic number of 92. 238 is the mass number of this particular isotope. The hypothetical product would have an atomic number of 92 - 2 ⨯ 2 + 1 = 89. Actinium has atomic number 89. As a result, the product is an isotope of actinium. The mass number of this hypothetical isotope would be 238 - 2 ⨯ 4 = 230. Therefore, actinium-230 is produced.
The overall nuclear reaction would involve five different particles. On the reactant side, there is
On the product side, there are
- one actinium-230 atom,
- two alpha particles (a.k.a. helium-4 nuclei),
- one electron, and
- one gamma particle (a.k.a. photon).
Consider: what would be the products if the nucleus undergoes a β⁺ decay instead?
