Chicken eggs are used as host and this can be a problem for people with egg allergies!!
The first option is correct.
Answer:
m Br = 439.472 g
Explanation:
mass Br = ?
∴ mol Br = 5.50 mol
∴ molar mass Br 79.904 g/mol
mass = (mol)*(g/mol)
⇒ m Br = (5.50 mol)*(79.904 g/mol)
⇒ m Br = 439.472 g
Answer:
are gases at room temperature
usually do not react with other elements
are in a group called the noble gases
are nonmetals
Explanation:
The elements in group 18 or group O are the inert elements. They have completely outermost shell and are not reactive. Every atom reacts with another in order to be like the noble gases.
- All of the elements here are gaseous.
- They do not readily react with other elements.
- They are called noble gases, inert gases, or group O elements.
It should be noted that group 17 elements are very reactive compared to the group O elements.
