Answer: 5.44×10226.022140857(74)×1023⋅mol−1.
Explanation: So the answer is approx. 0.10⋅mol
Answer: 
and 
and 
and 
and 
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
For the given chemical equations:
1. 
Here, is loosing a proton, thus it is considered as an acid and after losing a proton, it forms which is a conjugate base.
2. 
Here, is loosing a proton, thus it is considered as an acid and after losing a proton, it forms 
which is a conjugate base.
3. 
Here, is loosing a proton, thus it is considered as an acid and after losing a proton, it forms which is a conjugate base.
4. 
and 
are not conjugate acid/ base pairs.
5. 
Here, is loosing a proton, thus it is considered as an acid and after losing a proton, it forms which is a conjugate base.
Answer:
79.904 grams.
Explanation:
The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Bromine, or 79.904 grams.
2 HBr + Mg(OH) 2 yields Mg(Br) 2 + 2 H2O
M1V1 = M2V2
(0.245 M)(37.5 mL) = (M2)(18.0 mL)
9.1875 = (M2)(18.0 mL)
9.1875/(18.0 mL) = (M2)(18.0 mL)/(18.0 mL)
0.51041
this is not the complete answer as the mol to mol ratio must be considered!
For every 2 mols of HBr there is 1 mole of <span>Mg(OH)2; ratio = 2:1
</span>0.51041 / 2 = 0.25520
M2 = 0.25520
0.25520 M of<span> Mg(OH)2 solution</span>
Answer:
conclusion
Explanation:
it can't be a hypothesis since tests are carried out to verify so it is not a theory
an introduction to an experiment only gives the basis of what we are investigating therefore nothing has been proven and the question is still unanswered
