As a diprotic acid, the H₂SeO₃ can ionize by step. First step is H₂SeO₃ =(reversible reaction) H⁺ + HSeO₃⁻. And second step is HSeO₃⁻ =(reversible reaction) H⁺ +SeO₃ ²⁻.
Answer:
<em><u>700N</u></em>
Explanation:
<em><u>F</u></em><em><u>=</u></em><em><u>ma</u></em>
<em><u>mass</u></em><em><u>=</u></em><em><u>35</u></em>
<em><u>acceleration</u></em><em><u> </u></em><em><u>=</u></em><em><u>20</u></em>
0.0760 m
do this by:
finding the moles of NaOH which will be <span>5.702 E -3 m
</span>
next find the moles of H3PO4 which will be <span>1.90 E -3 m</span><span>
calulcate </span>25 ml sample molarity = 0.07603 m, just put 0.0760<span>
</span>
Answer:
negative
Explanation:
When something slows down, its acceleration is the opposite of the velocity.
A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in another
