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

7. Jasmine wants to prevent getting burned by accidently touching a hot metal pipe, What would be the worst
tatyana61 [14]

Answer:

A) Glass

Explanation:

Glass is a conductor, so it allows heat to go through it (Ex. Touching a pie pan that came right out of the oven)

Rubber is an insulator, so heat has a hard time passing through (Ex. Using a rubber grip on a cast iron pan.

Cloth is also an insulator, so heat has a hard time passing through (Ex. Using a pot holder to prevent the counter from getting scarred)

Wood is also an insulator, so heat has a hard time passing through (Ex. Bedding for a rabbit hutch)

Hope this helps!!
