Answer : The polyatomic ion with the formula $HPO_4^{2-}$ is called hydrogen phsophate ions.

Explanation :

The rules for naming the ionic compounds with polyatomic ion is given as :

The positive ion (cation) is written first.
The negative ion (anion) is written next.
The suffix is added at the end of the negative ion (anion). The suffix used is '-ate'.

In $HPO_4^{2-}$ , hydrogen ion combine with phosphate ion to give hydrogen phosphate ion.

Hence, the polyatomic ion with the formula $HPO_4^{2-}$ is called hydrogen phsophate ions.

Order the following expressions by their values from least to greatest

Licemer1 [7]

Answer:

Step-by-step explanation:

a = -1

b = 2

c = 3

a + (-c) = -1 + (-3) = -4

Both numbers have same sign(-Ve).So add and the result will have the -Ve sign.

c - (-b) = c + b = 3 + 2 = 5

b = 2

Least to greatest: a +(-c) , b , c-(-b)

(b) A bag contains five red counters and 3 blue counters. One counter is taken at random from the bag. What is the probability o

densk [106]

Answer:

<h2>p(obtaining a red counter) = 0.625</h2>

Step-by-step explanation:

The total number of counters in the bag is 5 + 3 = 8.

and only 5 are red.

Then

the probability of obtaining a red counter is :

$= \frac{5}{8} = 0.625$

Find the value of H:

rewona [7]

Answer:

The value of H is 28.

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(H-6)/(-7-(-5))

m=(H-6)/(-7+5)

-11=(H-6)/-2

-11(-2)=H-6

22=H-6

H=22+6

H=28
