Answer:
ABRAHAM DIDN’T THINK ISAAC WOULD DIE!
When they reached the mountain, Abraham told his servant, “Stay here with the donkey; I and the boy will go over there and worship and come again to you” . The text is careful to include both Abraham and Isaac in the return journey.
Or consider Isaac’s question about where the lamb for the sacrifice would come from. Abraham responds, “God himself will provide the lamb”. It seems Abraham prepared himself to do what God asked, but he expected something else to happen.
The author of the book of Hebrews gives us insight to Abraham’s thoughts. It says, “He considered that God was able even to raise [Isaac] from the dead” Instead of a resurrection, Abraham was spared the sacrifice.

The London forces designated as A are much weaker than the dipole- dipole interaction designated as B.
The intermolecular forces are interactions that exists between molecules of a substance in a particular state of matter. The nature of intermolecular forces in a substance greatly affect the properties of the substance.
We can see that A represents weak London forces while B represents dipole - dipole interactions. The London forces are very much weaker than the dipole - dipole interactions.

Use the heat equation to find out how many joules of energy are needed
to raise the temperature of 67 grams of water form 20°C - 45°C. What is the
answer in kilojoules?
(specific heat of water is 4.2 J/gºC.)
Answer:
About 7.0 × 10³ J or 7.0 kJ
Explanation:
We want to determine the amount of energy needed to raise the temperature of 67 grams of water from 20°C to 45°C.
We can use the heat equation:
[tex]\displaystyle q = mC\Delta T[/tex]
Where C is the specific heat of water.
Substitute and evaluate:
[tex]\displaystyle \begin{aligned} q & = (67\text{ g})\left(\frac{4.2\text{ J}}{\text{g-$^\circ$C}}\right)\left(45^\circ \text{ C}- 20.^\circ\text{ C}\right) \\ \\ & = (67\text{ g})\left(\frac{4.2\text{ J}}{\text{g-$^\circ$C}}\right)(25^\circ \text{ C}) \\ \\ & = 7.0\times 10^3 \text{ J}\end{aligned}[/tex]
Recall that there are 1000 J in a kJ. Hence:
[tex]\displaystyle \begin{aligned} q & = 7.0\times 10^3 \text{ J} \cdot \frac{1\text{ kJ}}{1000\text{ J}} \\ \\ & = 7.0 \text{ kJ}\end{aligned}[/tex]
In conclusion, it will take about 7.0 × 10³ J or 7.0 kJ of energy to raise the temperature of 67 grams of water from 20 °C to 45 °C.
Draw the Lewis Structure for C2F4. b. Total RED's c. Nonbonding RED's d. Electron-Pair Geometry e. Molecular Shape f. Is it Polar, Nonpolar or Ionic
The molecule C2F4 has a trigonal planar molecular and electron pair geometry.
The shape of a molecule is dependent on the number of electron pairs that surround the central atom in the molecule. In the molecule C2F4, there are two central carbon atoms.
Each of the central carbon atoms have a trigonal planar molecular and electron pair geometry. C2F4 is a symmetrical molecule so it is nonpolar and has a zero dipole moment.

An unknown substance has a boiling point of 174°C. Which statement is true about this unknown substance?
a) It has a higher boiling point than water, and it likely has stronger electrostatic forces between its molecules than water.
b) It has a higher boiling point than water, and it likely has weaker electrostatic forces between its molecules than water.
c) It has a lower boiling point than water, and it likely has weaker electrostatic forces between its molecules than water.
D) It has a lower boiling point than water, and it likely has stronger electrostatic forces between its molecules than water.
Answer:
It has a higher boiling point than water, and it likely has a stronger electrostatic forces between its molecules than water.
Explanation:
The unknown substance has a higher boiling point than water, and it likely has stronger electrostatic forces between its molecules than water.
What is the meaning of Boiling Point ?The temperature at which a liquid's saturated vapour pressure equals the air pressure surrounding it is known as the boiling point.
It is given that an unknown substance has a boiling point of 174°C.
The boiling point of water is 100°C.
So the boiling point of the unknown substance is higher than that of water.
Higher boiling point signifies more heat required to break the bonds.
Higher boiling point means existence of strong non covalent bonds.
This means it likely has stronger electrostatic forces between its molecules than water.
Therefore Option A is the correct answer.

Covalent compounds are generally not very hard. Justify the statement.
Covalent compounds are generally not very hard because they are formed by two or more nonmetallic atoms.
COVALENT COMPOUNDS:Covalent compounds are compounds whose constituent elements are joined together by covalent bonds.
Covalent bonding occurs when two or more nonmetallic atoms of an element share valence electrons. This means that covalent compounds will not be physically hard since they constitute non-metals.

2.Closed System: A closed system is a thermodynamic system where energy can be exchanged with its surrounding but not matter. Open System: Open systems can exchange matter with the surrounding. Closed System: Closed systems cannot exchange matter with the surrounding. Open System: The mass of the system will vary with time in open systems.

1.The particle model is the name for the diagrams used to draw solids, liquids and gases. In the model, the particles are shown as circles or spheres. However, the particles in ice, liquid water and steam look the same because they are all water, but in different states of matter. Why do we use the particle model in science?
3.An open system can be defined as a system which can exchange both matter and energy with the surrounding. For example, the earth can be recognized as an open system. In this case, the earth is the system, and space is the surrounding. Sunlight can reach the earth surface and we can send rockets to space.
Gaseous chlorine dioxide (ClO2) is used in bleaching flour and municipal water treatment in
500.0L containers. If these processes are performed at room temperature (22.0°C) using 52.1
moles of gas, what is the pressure? Must show calculation setup.
Taking into account the ideal gas law, the pressure is 2.52 atm.
An ideal gas is a theoretical gas that is considered to be composed of randomly moving point particles that do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.
The pressure, P, the temperature, T, and the volume, V, of an ideal gas are related by a simple formula called the ideal gas law. This equation relates the three variables if the amount of substance, number of moles n, remains constant. The universal constant of ideal gases R has the same value for all gaseous substances. The numerical value of R will depend on the units in which the other properties are worked.
P×V = n×R×T
In this case, you know:
P=?V= 500 Ln= 52.1 molesR= 0.082[tex]\frac{atmL}{molK}[/tex]T= 22 C= 295 K (being 0 C=273 K)Replacing in the ideal gas law:
P×500 L = 52.1 moles ×0.082 [tex]\frac{atmL}{molK}[/tex] ×295 K
Solving:
P= (52.1 moles ×0.082 [tex]\frac{atmL}{molK}[/tex] ×295 K)÷ 500 L
P= 2.52 atm
Finally, the pressure is 2.52 atm.

Equilibrium concentration of HOCl at 25°C is 0.140 M
The equation of the reaction at equilibrium is given below:
H₂O (g) + Cl₂O (g) ⇄ 2 HOCl (g)
Equilibrium constant, Kc = 0.0900 at 25°C
An ICE chart for the reaction is set up below
H₂O (g) + Cl₂O (g) ⇄ 2 HOCl (g)
I 0.384 0.384 0.652
C -x -x + 2x
E 0.384 - x 0.384 - x 0.652 + 2x
The equation of the equilibrium constant is given as;
Kc = [tex]\frac{[HOCl]^2}{[H_{2}O][Cl_{2}O]}[/tex]
substituting the values into the equation:
Kc = [tex]\frac{(0.652 + 2x)^2}{( 0.384 - x)( 0.384 - x)}[/tex] = 0.0900
4x² + 2.608x + 0.425 = 0.0900 (0.147 - 0.768x + x²)
4x² - 0.09x² + 2.677x - 0.069x + 0.425 - 0.013 = 0
3.910x² + 2.677x + 0.412 = 0
Solving using the quadratic formula:
a = 3.910, b = 2.677, c = 0.412
x = [tex]\frac{-2.677\±\sqrt{2.677^2 - 4*3.910*0.412}}{2*3.910}[/tex]
x = -0.256 or -0.431
The negative sign indicates that equilibrium is to the left of the reaction
Since x cannot be greater than 0.384, x = -0.256.
Equilibrium concentration of HOCl = 0.652 + 2(-0.256)
Equilibrium concentration of HOCl at 25°C is 0.140 M
