The answer is conductors
You welcome : )
Density=mass / volume
Data:
mass=30.0 g
volume=volume with rock - volume without rock=27.6 ml - 22.3 ml=5.3 ml
1 ml=cm³ ⇒ 5.3 ml=5.3 cm³
Therefore:
Density=30.0 g / 5.3 cm³=5.66 g/cm³
Answer: density = 5.66 g/cm³
Answer:
<u>2HClO(aq) + Ba(OH)₂(aq)</u> → Ba(ClO)₂(aq) + 2H₂O(l)
Explanation:
The reaction corresponds to a neutralization reaction between an acid and a base, as follows:
2HClO(aq) + Ba(OH)₂(aq) → Ba(ClO)₂(aq) + 2H₂O(l)
From the equation above we have that the acid HClO reacts with the base Ba(OH)₂ to obtain a salt Ba(ClO)₂ and water.
In the balanced reaction, we have that 2 moles of HClO react with 1 mol of Ba(OH)₂ to produce 1 mol of Ba(ClO)₂ and 2 moles of water.
I hope it helps you!
Flame test is a qualitative test which is used to identify the metal and metalloid ion in the sample.
<h3>What is Flame Test ?</h3>
A Flame test is used to identify the metal and metalloid ion in the sample. Flame test is a qualitative test. Not every metal ion emit color when it is heated in the gas burner.
<h3>What is the Purpose of Flame test ?</h3>
The purpose of flame test is used to find the identities of ions in two solutions of unknown composition by comparing the colors they produce.
<h3>What are the material used ?</h3>
- Bunsen Burner
- Matches
- Gloves
- Weighing dishes
- Beakers
Thus from the above conclusion we can say that Flame test is a qualitative test which is used to identify the metal and metalloid ion in the sample.
