How many nitrate ions are in 387.4 grams of calcium nitrate?

60.6 g

Explanation:

The balanced equation for the given reaction is:

It is a grams to grams conversion problem. Here, first of all the given grams of calcium nitrate are converted to moles on diving by its molar mass. Then it is multiplied by the mol ratio to get the moles of calcium phosphate and finally multiplied by molar mass of calcium phosphate to get its grams.

From balanced equation, there is 3:1 mol ratio between calcium nitrate and calcium phosphate.

Molar mass of calcium nitrate is 164.088 g per mol and the molar mass of calcium phosphate is 310.18 g per mol.

= So, the mass of calcium phosphate the reaction can produce is 60.6 g.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
