Question 67 of 75 ISA
When chromium metal is added to nitric acid, the following reaction
takes place
Cr (s) + 6 HNO3 (aq) → Cr(NO3)2 (aq) + 3 H20 (1) + 3 NO2 (g)
Calculate the volume of NO2 gas (in L) collected over water at 40.0 °C
when 19.3 g of chromium is added to excess nitric acid if the total
pressure is 675.0 torr. The vapor pressure of water at 40.0 °C is 55.3
torr.

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.

"the periodic table is arranged in order of atomic number."
