A 1.83 mol sample of carbon reacts with excess zinc oxide to produce zinc and carbon dioxide. How many moles of zinc oxide are c
dusya [7]

Answer:

3.66 moles of Zinc Oxide are consumed

Explanation:

Based on the reaction:

C + 2ZnO → 2Zn + CO₂

<em>Where 1 mole of Carbon reacts with 2 moles of Zin Oxide to produce 2 moles of Zinc and 1 mole of Carbon Dioxide.</em>

<em />

To solve this question, we must convert the moles of carbon added to the moles of Zinc Oxide that react using the chemical equation (1mol C = 2mol ZnO):

1.83 moles C * (2mol ZnO / 1mol C) =

<h3>3.66 moles of Zinc Oxide are consumed</h3>

You add 100. 0 g of water at 60. 0°c to 100. 0 g of ice at 0. 00°c. Some of the ice melts and cools the water to 0. 00°c. When t

The Mass of ice is 69.12g.

What is mass?

It is a dimensionless quantity that expresses a particle or object's mass. The accepted unit of mass under the International System (SI) is the kilogram.

What is temperature?

Temperature is a measure of the average kinetic energy of the particles inside an object. The temperature increases cause these particles to move more quickly. It is possible to measure temperature using a thermometer or a calorimeter.

first calculate the amount of heat as follows;

q= mass of water C= (0°C-55°C)

=100.0g (4.186J/g°c) (-55°C)

=-23023J

Heat lost by water is gained by ice,

-q=m*ΔH

-23023J= m*333J/g

= 69.12g

Therefore, Mass of ice is 69.12g.
