Question 1 Write a balanced molecular equation for the addition of 1M H3PO4 + 3M NaOH and 3M HCl + 1M Na3PO4 together

question 2

Are the experimental ΔTs of reactions #1, 3, and 4 related if so explain why

reaction 1

3M HCl + 3M NaOH

reaction 3

1M H3PO4 + 3M NaOH

reaction 4

3M HCl + 1M Na3PO4

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
