That would result in an exothermic reaction.
Hope this helps :)
Answer:
reacts with an acidic solution
Explanation:
Scandium Oxide is a basic metal oxide which therefore reacts with acidic solution. An oxide is a compound that contains only two elements, one of which is oxygen .
The objective of this question is to Write a balanced chemical equation to support your answer.
The chemical equation to support the reaction of with acidic solution is as follows:
Assuming the acidic solution to be HCl
The ionic equation :
Z=1 is the formula i would have to see the following lol
<span>In H2CO, C is bonded to H, H and O. Write down the valence electrons of each element.
2 H = 1x 2 = 2.
C= 4
O = 6
Total 12 </span>
Answer:
41.4 grams of NaOH
Explanation:
Molarity is the data of moles of solute in 1L of solvent, so 2.3 moles of NaOH are contained in 1L or which is the same, 1000mL.
Let's find out the moles in our volume 450 mL by a rule of three:
In 1000 mL we have 2.3 moles
In 450 mL we have (450. 2.3)/1000 = 1.035 moles
Moles . molar mass = mass
1.035 m . 40 g/m = 41.4 g
