A beaker containing 75.0 mL of 0.22 M AgNO3 is mixed with excess Na2SO4 solution. How many grams of precipitate, Ag2SO4, are formed during this reaction? Na2SO4(aq) + AgNO3(aq)¦ Ag2SO4(s) + NaNO3(aq)

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.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
