Alkina metals all have the similar proteries
A size force of 5N will be exerted on Artl's foot.
This is because Newton's third law of motion, where in which an action occurs, a reaction will occur with the same amount of force, but reversed towards the direction of the area where the action occurred.
I guess it is the second one but you missed the state symbols.
Answer:
False
Explanation:
The octet rule forms the basis for chemical reactions. The octet rule states that; an atom is only stable when it has eight electrons around its outermost shell.
This implies that the driving force behind chemical reaction is the attainment of an octet structure(eight electrons in the outermost shell of each of the bonding atoms).
An atom that has only six electrons in its outermost shell is not yet stable according to the demand of the octet rule. Hence, the statement "chemical reactions happen and compounds form because they're trying to get 6 electrons in their outer orbitals" is false.
Answer:
Final temperature of water is 
Explanation:
1 mol of LiBr releases 48.83 kJ of heat upon dissolution in water.
So, 2 moles of LiBr release 
or 97.66 kJ of heat upon dissolution in water.
This amount of heat is consumed by 1000.0 g of water. Hence temperature of water will increase.
Let's say final temperature of water is 
.
So, change in temperature (
) of water is 
or (t-25) K
Heat capacity (C) of water is 
Hence, 
where m is mass
So, 
or, 
Hence final temperature of water is
