Calculate the amount of energy when water at 72 degrees c freezes completely at 0 degrees c
gtnhenbr [62]

<u>Answer:</u>

<em>The amount of energy needed when water at 72 degrees c freezes completely at 0 degrees c is 6.37\times10^4 Joules</em>

<em></em>

<u>Explanation:</u>

Q = m \times c \times \Delta T

where

\Delta T = Final T - Initial T

$Q_{1}=100 g \times 4.184 \frac{J}{g^{\circ} \mathrm{C}} \times\left(72^{\circ} \mathrm{C}-0^{\circ} \mathrm{C}\right)$

Q_1 =30125J

Q is the heat energy in Joules  

c is the specific heat capacity (for water 1.0  cal/(g℃))  or 4.184  J/(g℃)

m is the mass of water

mass of water is assumed as 100 g (since not mentioned)

Q_2  is the heat energy required for the phase change

Q_2 =mass × heat of fusion

\\$Q_{2}=100 g \times 336 \frac{J}{g}$\\\\$Q_{2}=33600 J$

Total heat = Q_1 + Q_2

Total Heat = 30123J + 33600J

= 63725 J

= 6.37\times10^4 Joules is the answer

PLEASE HELP ALL OTHER ANSWERS ON BRAINLY ARE INCORRECT AS THEY ARE ALL THE SAME HELP!!! WILL MARK BRAINLIEST!!! Give the quantum
stealth61 [152]

it can form 3 bonds because 1 electron is in each of the 3 2p oribitals.

The electron configuration of nitrogen (atomic number 7) is 1s2 2s2 2px1 2py1 2pz1

so specifically the 2p oribital is :

2px1 2py1 2pz1

What is 5L to mL ( chemistry )
zlopas [31]

There are 1000 mililiters in a liter, so 1000 ml for every liter, you have 5 liters, so:

5L*1000 = 5000 mL

The strength of an atom's attraction for the electrons in a chemical bond is the atom's?
Mazyrski [523]

<span><span>Yes. An element that is highly electronegative pulls more on the electrons in a bond, such as oxygen in H20. This creates a polar bond, where there is a small negative charge on the oxygen, and a small positive charge in between the hydrogens.
