Answer:
caO
Explanation:
Among the given options, Calcium Oxide (CaO) contains an ionic bond. This bond is formed through the transfer of two electrons from a calcium atom to an oxygen atom.
The question seeks to identify the compound that contains an ionic bond from the provided options. Ionic bonds are usually formed between metals and non-metals. In these cases, the metal atom donates an electron to the non-metal atom, leading to the formation of a positively charged cation and a negatively charged anion. These oppositely charged ions then attract each other, forming an ionic bond.
Let's look at the options:
#SPJ6
Answer:
A. 120m
Explanation:
just took the test
b.It is a heterogeneous catalyst, so only a small amount is needed and it is easily separated from the products.
c.It is a homogeneous catalyst, so although a large amount is needed, it is easily separated from the products.
d.It is a heterogeneous catalyst, so a large amount is needed and it exits with the products.
Answer:
B EDGE 2022
Explanation:
Answer:
The reaction would be 1500n (equal reaction)
Explanation:
This can be explained by Newton's third law of motion which states that for every action (force), there is an opposite and equal reaction. In other words, when two objects or people come in contact, the magnitude of force which they exert on each other is equal and they both feel an equal reaction force.
It doesn't matter whether one of the colliding bodies is of bigger mass than the other. This Newton's third law of motion is also known as the law of action and reaction.
Answer: The water is highly corrosive when the saturation index < - 0.5 and
> 0.5
Explanation:
If the saturation index for a pool measures the balance between the acid level and the amount of minerals in pool water. Considering its balanced water has an index value of 0.
The water is highly corrosive when the saturation index < - 0.5 and
> 0.5
The attachment below shows the calculations.
Answer: H₂SO₄ is the chemical formula that represents sulfuric acid.
Explanation:
1) H stands for hydrogen and H₂ means that each unit contains two atoms of hydrogen.
2) S stands for sulfur. Since there is not subscript, means each unit contains one atom of sulfur.
3) O stands for oxygen, and O₄ means that each unit has four oxygen atoms.
4) The way the compound is build up is the S atom at the center with two double bonds to each to one atom of O, and two single bonds one to each OH ion.
5) Sulfuric acid is a strong acid, so it dissociates in water and alghough the formula H₂SO₄ is used to represent it, the aqueous solution is formed by ions: HSO₃⁻, H⁺, SO₄²⁻, and OH⁻, as represented by these dissociation equaitons show:
1) H₂SO₄ ⇄H⁺ + HSO₄⁻ first dissociation
2) HSO₄⁻ ⇄ H⁺ + SO₄²⁻ second dissociation
So, H₂SO₄ is one form to represent sulfuric acid.
In an aqueous solution, H₂SO₄ represents sulfuric acid.
In an aqueous solution, H₂SO₄ represents sulfuric acid. Sulfuric acid is a strong diprotic acid that ionizes in two stages. The first stage is essentially complete in an aqueous solution, while the secondary ionization is less complete, resulting in the formation of HSO₄⁻, which is a moderately strong acid.
