Plsss help me with thiss b) NaOH + HCl =
c) Na2O + H20 =
d) P + O2 =
e) S + O2 =
f) Na + H2O =​

a)Hydrochloric acid reacts with sodium hydroxide to form sodium chloride (the salt) and water. Sodium chloride is made up of Na+ cations from the base (NaOH) and Cl- anions from the acid (HCl). HCl+NaOH→H2O+NaCl.

b) Na2O + H2O → 2 NaOH - Balanced equation

c) P2O5

d) SO2

f)  Na + H2O = NaOH + H2

Explanation:

Hope this helps!

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
