Answer:
0.492 lb/in^3
Explanation:
From Density of Mercury (13.6g/cm3) given,
Mass = 13.6g
Volume = 1cm3
Now we covert these variables as follows :
For Mass:
454 g = 1 lb
13.6g = 13.6/454 = 0.03lb
For volume:
2.54 cm = 1 in
1cm = 1/2.54 = 0.394in
Volume = (0.394in)^3 = 0.061 in^3
Density = Mass /volume
Density = 0.03lb/0.061 in^3
Density = 0.492 lb/in^3
Answer:
The correct option is The net ionic equation shows the spectator ions in the reaction.
Explanation:
The net ionic reaction will show us the ions which are involved in the reaction. It also helps us the charges present on each atom and how a reaction occurs due to these charges on atoms. It shows us that which ions actually take part in a chemical reaction and which ions do not take part in the reaction and are involved only for balancing the equation.
Answer:
Explanation:
A homogenous mixture is a mixture is the same throughout. Some examples are clean water, milk, oil, and food colouring.
Atoms “stick” to each other because they all try to get into a noble gas configuration. Which simply means that they try to reach a amount of electrons equal to noble gasses, this property makes simple atoms like water stable. I hope this helps! Have a great day and stay safe!
