Answer:
1.VOLUME– The amount of space an object takes up. Basic Unit (SI Unit) for Solids – Cubic Meter, m3. LENGTH/DISTANCE – The measurement between two points.
2.one particle per cubic meter.
3.it means it is heavier
4.In a liquid the particles are still close together but a little further apart than in a solid.
5.In gases the particles are much further apart than in solids or liquids.
Explanation:
thats all i can type lol
Answer:
0.1 moles of electrons
Explanation:
Electroplating is a process in which a metal is used to cover the surface of another metal for protection or beautification purposes.
The reduction of the silver is captured in the equation;
Ag^+(aq) +e ------> Ag(s)
We were already told in the question that the mass of silver is 108g
1 mole of electrons is needed to deposit 108g of silver
x moles of electrons is required to deposit 10.8 g of silver
x= 1 ×10.8/108
x= 0.1 moles of electrons
Answer:
The volume of the piece of iron is 5.18dL.
Explanation:
The density (ρ) is equal to the mass (m) divided the volume (V).
If we rearrange it, we have:
To express the volume in dL we will need the following relations:
- 1 dL = 0.1 L
- 1 kg = 10³ g
- 1 cm³ = 1 mL
- 1mL = 10⁻³L
Then,
Finally,
Answer
D. propyl butanoate
Explanation:
The general formula of an ester is RCOOR'. Esters are named as if the alkyl chain from the alcohol is a substituent. No number is assigned to this alkyl chain. This is followed by the name of the parent chain from the carboxylic acid part of the ester with an –e remove and replaced with the ending –oate.
Therefore, the name of the given ester molecule is:
D. propyl butanoate.
