What is the value of the specific heat capacity of liquid water in j/mol·°c?

2 answers:

Since your units said j/mol. C, which means you are looking for molar heat capacity, then that is 75.40 j $mol^{-1} C^{-1}$

Specific heat capacity of water in j $g^{-1} C^{-1}$ is 4.184, which has a mass unit in grams.

The molar heat capacity of water at liquid temperature is 75.40 j $mol^{-1} C^{-1}$ , which takes the same units as you presented in your question.

Help please! What is the mass of the iron (Fe) involved in this reaction? Identify the following equations as balanced or unbala

eimsori [14]

<h2>Question 1:</h2><h3>32g + <u><em>56g</em></u> --> 88g</h3>

This one's just a simple math problem. Do 88 - 32, which is 56. You can also find the same answer by looking for the atomic mass of iron (Fe), which rounds up to 56.

<h2>Question 2:</h2><h3>This equation is <u><em>balanced</em></u>.</h3>

On the left side, there is 2 Nitrogen (because of the subscript), and 6 Hydrogen (3 x 2 = 6). On the right side, there is 2 Nitrogen (because of the coefficient), and 6 Hydrogen. (2 x 3 again) There are 2 Nitrogen and 6 Hydrogen on each side, therefore the equation is balanced.

<h2>Question 3:</h2><h3>This equation is <em><u>unbalanced.</u></em></h3>

On the left side, there are 2 Nitrogen (N) and 2 Hydrogen (H). On the right side, there is 1 Nitrogen and 6 Hydrogen. There are 2 Nitrogen and 2 Hydrogen on one side, while the other only has 1 Nitrogen and 6 Hydrogen. Therefore the equation is unbalanced.

<h2>Question 4:</h2><h3>This equation is <em><u>balanced.</u></em></h3>

On the left side, there are 2 Chromium (Cr) and 6 Chlorine (Cl). On the right side, there are 2 Chromium and 6 Chlorine. There are 2 Chromium and 6 Chlorine on each side, therefore the equation in balanced.

How many atoms are there in 10.2 moles of Phosphorous?

nikdorinn [45]

There are 2.06 x 10²⁴ atoms

<h3>Further explanation </h3>

The mole is the number of particles (atoms, molecules, ions)contained in a substance

1 mol = 6.02.10²³ particles

Moles can also be determined from the amount of substance mass and its molar mass

number of atoms :

$\tt 10.2\times 6.02\times 106{23}=2.06\times 10^{24}$
