Ammonium sulphate + __________________ potassium sulfate + ammonia + water
Please fill in the blank.
Answer:
Potassium Hydroxide Solution =
or
Potassium Hydroxide =
Since we know the products and one of the reactions, we can work backward to discover what the other reactant may be.
As it is in the question, we can map the reactants and product:
Reactants Product
Ammonium Ammonia
Sulfate Sulfate
________ Potassium
________ Water
Since the reaction will yield Potassium and water, the likely reactant is Potassium Hydroxide (KOH). This is because we know that Ammonium lost a Hydrogen atom that could combine with the Hydroxide radical to form water.
This becomes clear when we consider the net ionic equation:
Ammonium sulphate + Potassium Hydroxide → potassium sulfate + ammonia + water
if we write this a balanced chemical equation:
(NH₄)₂SO₄ + 2KOH → K₂SO₄ + 2NH₃ + 2H₂O
if we write the reaction as an ionic equation
2NH₄⁺ + SO₄⁻ + 2K⁺ + 2OH⁻ → 2K⁺ + SO₄⁻ + 2NH₃ + 2H₂O
if we remove the ions that appear on both the reactant and product side (spectator ions)
2NH₄⁺ + 2OH⁻ → + 2NH₃ + 2H₂OPhản ứng tương tác của ancol tạo thành este được gọi là
Using the formula velocity = distance/time, how fast does sound travel in wood given a distance of 500 m and 0.26 seconds.

B- 746 m/s
C- 2,941 m/s
D- 127 m/s
Answer:
A : 1,923 m/s
Explanation:
= 500/0.26
= 1,923
In terms of attractive forces, explain why LiClhas a higher melting point than SCI2.
Answer:
Well, SCl2 is known, so is disulfur dichloride… Cl−S−S−Cl …and BOTH these species are molecular… On the other hand, lithium chloride, an ionic salt, is decidedly non-molecular, and consists of an infinite array of lithium and chloride ions held together by strong electrostatic forces ….. and thus we would expect the salt to have the much higher melting point….
What is true of a saturated solution?
Answer:
A saturated solution is a solution that contains the maximum amount of solute that is capable of being dissolved. At 20°C, the maximum amount of NaCl that will dissolve in 100. g of water is 36.0 g. If any more NaCl is added past that point, it will not dissolve because the solution is saturated.

how do ions form bonds, and describe the structure of the resulting compound.
Answer:
Electrons are transferred between atoms together in the ionic compound. The ions are arranged in a regular repeating pattern in an ionic crystal
Explanation:
Ions electrostatically attracts its counter ions and forms the ionic bond between these ions. The structure of ionic compounds depends on the number of atoms and bonded pair of electrons.
What is ionic bonding ?Ionic bonds are formed between metals and non-metals. Metals are electron rich and easily loss one or more electrons to the electron deficient non metals.
The loss of electrons make the atom forms a positive ion called cations. The gain of electrons make the formation of anions or negative ions. These positive ions and negative ions attracts electrostatically and forms ionic bond between them.
The structure of ionic compounds depends on the number of bonded atoms, size, presence of lone pairs etc. In solution ionic compounds exists as separate ions.

Explanation:
Ribosomes are called PROTEIN FACTORY
Ribosomes are involved in protein synthesis
Any metabolite or substance protein in nature can be synthesized on ribosomes
enzymes are protein in natureantibodies are y shaped protective proteinswater soluble hormones are also amine or protein in natureSince they are protein in nature hence can be synthesized on ribosome.

o The number of valence electrons increases from right to left.
O The number of valence electrons increases from left to right.
O The number of valence electrons increases from bottom to top.
O The number of valence electrons increases from top to bottom.
Answer:
The number of valence electrons increases from left to right.
Explanation: The number of valence electrons increases going across a period, or row in the periodic table, for example, group 1 elements have 1 valence electrons and group 2 elements have have 2.
An atom of radium (Ra) forms a monatomic ion.
Which ion does it most likely form?
a- Ra2-
b- Ra-
c- Ra2+
d- Ra+
Answer:
The atomic number of the element Radium (Ra) is 88. It is an alkaline earth metal. Electronic configuration of Radium (Ra) will be [Rn]7s^{2}[Rn]7s
2
It belongs to the group IIA of the periodic table. Alkaline earth metals that belong to the group IIA of the periodic table lose the valence electrons to form a +2 ion.
Therefore, Radium with an electronic configuration of [Rn]7s^{2}[Rn]7s
2
will lose the two 7s electrons to form the cation with +2 charge.

how do you determine the thermal energy of an object
Answer:
An object's thermal energy is dependent upon its temperature and mass. The higher the temperature of a given quantity of a substance, more is its thermal energy. Similarly, for the same temperature, higher mass of a substance will contain more thermal energy
