What  is  the  net  ionic equation
2 H^+  + SO4^2-  + Ca^2+  +  2 i^- = CaSo4  + 2H^+  +2i ^-
cancel  the spectator  ion that is the  ions  which  does  not take  place  nin  the  reaction

for this  case  is  2 H^+  and 2 i^-

the net ionic equation  is  therefore
=Ca^2+  + SO4^2- = CaSO4

How many moles of ammonia (nh3 will be produced from 4.0 moles of nitrogen (n2?
Lana71 [14]
Standard equation would be N2(g)+3H2(g)==>2NH3(g), so through stoichiometry, (4 mol N2)(2mol NH3/1 mol N2), assuming excess H2, would yield 8 moles of NH3.

How many moles are equal to 1.3 x 1024 atoms of aluminum?
marshall27 [118]

Answer:

<h3>The answer is 2.16 moles</h3>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L}  \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{1.3 \times  {10}^{24} }{6.02 \times  {10}^{23} }  \\  = 2.159468...

We have the final answer as

<h3>2.16 moles</h3>

Hope this helps you
