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

2 answers:

6 0

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.

Which of the following would increase the strength of an electromagnet? Check all that apply.

TiliK225 [7]

Answer: The correct statements are ; A and B.

Explanation:

The strength of the magnetic field(B) in an electromagnet can be calculated using formula:

$B=\mu\frac{N}{L}I$

$\mu$ = Relative permeability

N = number of turns

I = Current in the wire of the solenoid

L = length of the solenoid or electromagnetic

As we can see from the formula:

$B\propto N$

$B\propto I$

So, by increasing the turns and increasing current flowing through wire one can increase the strength of an electromagnet.

Hence, the correct statements are ; A and B.

A material has a volume of 63.0 cm3 and a mass of 28 grams. What is the density of the material in g/cm3 to the correct number

dimaraw [331]

Answer:

0.4444 g/cm³ ≅ 0.44 g/cm³ (2 significant figures).

Explanation:

Knowing that:

d = m/V,

where, d is the density of the material (g/cm³).

m is the mass of the material (m = 28 g).

V is the volume of the material (V = 63.0 cm³).

∴ d = m/V = (28 g)/(63.0 cm³) = 0.4444 g/cm³ ≅ 0.44 g/cm³ (2 significant figures).

Virty [35]

Explain whether this is a chemical or physical change, and why. does it involve elements, compounds, mixtures, or pure substances?

If the process involves a chemical reaction then surely it is a chemical change where new bonds are being formed from the collision of the reactants.

Describe how many atoms are involved before and after. what do you notice about the number of atoms?

From the balanced chemical reaction, we see that we need 1 mol of N2 gas and 3 mol of H2 in order to form 2 mol of NH3.

Which statement is true at STP? (The atomic mass of Zn is 65.39 u.)

earnstyle [38]

Zinc is a metal. At STP, it exists as solid and is stable as it is. It is an important mineral and is used in many applications like in food, metal and drugs. Zinc can be found in the Earth's crust and also it is present in small amounts in some food.
