The answer is heat.
To use a glue gun, it has to use heat to heat up so that it can melt the glue.
The correct option is C.
A Lewis dot diagram is a representation of the valence electron of an atom, which uses dot around the symbol of the atom. Chlorine has seven electrons in its outermost shell, these seven electrons are arranged in form of dot around the atom of chlorine. If you count the number of dot given in option C, you will notice that they are seven.
Answer is: 1 megamole is equal to 1000000 (one million) mole or 10⁶<span> moles</span>.
The SI base unit for amount of substance is the mole. The SI prefix "mega" represents a factor of 10⁶, or in exponential notation, 1E6.
<span>The mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 12 grams of carbon C-12.</span>
Answer:
d:more dense and falls
Explanation:
warm air Rises around cold air bc of its lower density. and when you have a lower density fluid or sum the lower density fluid rises and the higher density falls
Ans: 4.73 moles
Given reaction:
2LiBr + Ba → BaBr2 + 2Li
Mass of Ba = 325 g
Atomic mass of Ba = 137.32 g/mol
# moles of Ba = 325/137.32 = 2.368 moles
Based on the reaction stoichiometry:
1 mole of Ba produces 2 moles of Li
Therefore, 2.368 moles of Ba will produce, 2.368*2 = 4.736 moles
