** will give you 15 points plus brainliest if you answer correctly ** the ph of four different substances is shown below. substance ph shampoo 6 lemon juice 2 tomato juice 4 liquid drain cleaner 14 which substance is closest to being neutral on the ph scale? a. shampoo b. lemon juice c. tomato juice d. liquid drain cleaner

Shampoo

Explanation:

The neutral pH is 7 when their is no acid or alkali and shampoo has the closest value to 7.

Lemon juice = Strong acid

Tomato juice = Moderate acid

Liquid drain cleaner = Very strong alkali

Shampoo

Explanation:

Water has a pH of 7 and water is a neutral substance so the closest thing to 7 would be shampoo :)

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.

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
