Write a balanced chemical equation based on the following description:
aqueous potassium phosphate reacts with aqueous nickel(II) bromide to
produce solid nickel(II) phosphate and aqueous potassium bromide.
Answers
the balanced chemical equation was shown here :
2 K3PO4 (aq) + 3 NiBr2(aq) ------------>> Ni3(PO4)2 (s) + 6 KBr (aq)
The balanced chemical equation when aqueous potassium phosphate reacts with aqueous nickel(II) bromide to produce solid nickel(II) phosphate and aqueous potassium bromide is:
2 K₃PO₄(aq) + 3 NiBr₂(aq) ⇒ Ni₃(PO₄)₂ + 6 KBr(aq)
Let's consider the unbalanced chemical equation that occurs when aqueous potassium phosphate reacts with aqueous nickel(II) bromide to produce solid nickel(II) phosphate and aqueous potassium bromide.
K₃PO₄(aq) + NiBr₂(aq) ⇒ Ni₃(PO₄)₂ + KBr(aq)
We will balance it using the trial and error method.
We will balance Ni atoms by multiplying NiBr₂ by 3.We will balance P atoms by multiplying K₃PO₄ by 2.2 K₃PO₄(aq) + 3 NiBr₂(aq) ⇒ Ni₃(PO₄)₂ + KBr(aq)
We will get the balanced equation by multiplying KBr by 6.
2 K₃PO₄(aq) + 3 NiBr₂(aq) ⇒ Ni₃(PO₄)₂ + 6 KBr(aq)
The balanced chemical equation when aqueous potassium phosphate reacts with aqueous nickel(II) bromide to produce solid nickel(II) phosphate and aqueous potassium bromide is:
2 K₃PO₄(aq) + 3 NiBr₂(aq) ⇒ Ni₃(PO₄)₂ + 6 KBr(aq)

Answers
The phrase that describes transmutation is ; ( A ) The conversion of an atom of one element into different element through nuclear changes.
Transmutation is simply the change of an element to another element, transmutation occurs at the nucleus of the atom of an element and this process is initiated through nuclear reaction ( radioactive decay ).
Therefore the conversion of an atom of one element into different element through nuclear changes summarizes the term "transmutation".
Hence we can conclude that the phrase that describes transmutation is the conversion of an atom of one element into different element through nuclear changes.

Potassium iodide is an ionic compound.
Describe what happens, in terms of electron loss and gain, when a potassium atom reacts
with an iodine atom.
Answers
Answer:
In this reaction, potassium atoms lose electrons to form positively-charged potassium ions (oxidation) and iodine atoms gain electrons to form negatively-charged iodide ions (reduction).
Explanation:
pls mark as brainliest
In this process, iodine atoms get electrons to produce negatively charged iodide ions, whereas potassium atoms lose electrons to form positively charged potassium ions. Oxidation and reduction takes place.
What is oxidation ?Redox reactions include a change in the oxidation state of the substrate. Similar to how reduction is the acquisition of electrons while oxidation is the loss of electrons or an increase in the oxidation state.
An oxidation process takes place when oxygen interacts with a substance or an element. Another way to think of oxidation is as the process of removing hydrogen from the species of reactants. Molecule, atom, or ion oxidation is the process of losing electrons.
Because they generate new functional groups in molecules or alter existing functional groups, oxidation processes are crucial in the synthesis of organic substances.
Thus, the iodine atom also experiences a change. The iodide atom gets one electron during the reaction with potassium, leaving it with eight electrons at its outer energy level.

How many moles of HCl will be produced when 34.56 g of AIC3 are reacted according to this chemical equation
Answers
Answer:The answer to your question is It will be formed 0.39 moles of H₂
Data
moles of H₂ = ?
moles of HCl = 0.78
moles of Zinc = excess
Balanced chemical reaction
2 HCl + Zn ⇒ 1 H₂ + ZnCl₂
Process
Explanation:
1.- Use proportions to solve this problem. Consider the coefficients of the balanced reaction.
2 moles of HCl ---------------------- 1 mol of H₂
0.78 moles of HCl ----------------- x
x = (0.78 x 1) / 2
- Simplification
x = 0.78 / 2
- Result
x = 0.39 moles of H₂
