Answer:
Explanation:
The dilution formula is:
Where M₁ and M₂ are the molar concentrations and V₁ and V₂ are the volumes of the concentrated and the diluted solutions.
Substitute:
Clear M₂ and compute:
The molecule is unstable and impossible to create the PCl_6
Only one way is that change the formula
Lets look at structure(See attachment)
There are total 7atoms
Answer:
Explanation:
1. First take the cylinder volume formula:
2. Then take the values for the radius and the height of the cylinder and replace them into the formula:
3. Solve the equation:
Answer: Option D) Salt
Explanation:
An example of acid-base reaction is
HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)
Acid + base → Salt + Water.
Here, water H2O and salt, NaCl are produced.
Usually, the acid, aqeous HCl reacts completely with an appropriate amount of the base, aqueous NaOH to produce salt, aqueous NaCl and water, liquid H2O only, in a process also known as neutralization reaction
Answer:
Strontium (St)
Explanation:
The atom that will have a larger radius than zinc is strontium, Sr.
Atomic radius is defined as the half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between two nuclei in the solid state of metals.
- Across the period atomic radii decreases progressively due to the increase in nuclear charge.
- Down a group atomic radii increase progressively due to the successive shells of electrons being added.
- Since strontium satisfies the criteria, it has the larger atomic radius.
