Reaction of Elemental Calcium with Water is as follow,

                        Ca  +  2 H₂O    →    Ca(OH)₂  +  H₂↑

When Sodium Metal is reacted with Water it produces NaOH and eliminates Hydrogen gas as shown in following equation,

                         2 Na  +  2 H₂O    →    2 NaOH  +  H₂↑

In both cases corresponding Hydroxides along with Hydrogen gas is produced.

For the following reaction, 28.6 grams of zinc oxide are allowed to react with 9.54 grams of water . zinc oxide(s) water(l) zinc
maw [93]

Answer:

34.9 g of Zn(OH)₂ is the maximum mass that can be formed

Explanation:

Let's state the reaction:

ZnO(s)  + H₂O(l) → Zn(OH)₂ (aq)

First of all, we need to determine the moles of each reactant and state the limiting:

28.6 g . 1mol /81.38 g = 0.351 moles of ZnO

9.54 g . 1mol /18 g = 0.53 moles of water

As ratio is 1:1, for 0.53 moles of water, we need 0.53 moles of ZnO, but we only have 0.351, so the limiting reactant is the ZnO.

Ratio with the product is also 1:1. From 0.351 moles of oxide we can produce 0.351 moles of hydroxide. Let's calculate the mass:

0.351 mol . 99.4 g /1mol = 34.9 g

Why is there a bond between the ions in potassium chloride
yKpoI14uk [10]

Answer:

Explanation:

When the two atoms are in contact, potassium transfers its outer electron to chlorine which readily accepts it, resulting in both atoms achieving a state of eight outermost electrons. With this electron transfer, the ionic bond in KCl is formed.

Hope this helped!!!
