Interestingly, Xenon has a high affinity for oxygen, and xenon fluorides are known to undergo hydrolysis to give the hydrohalic acid and the rare gas oxide similar to the following equation: XeF6 + 3H2O -> X + 6HF

Answers

Answer 1

xenon fluorides are known to undergo hydrolysis to give the hydrohalic acid and the rare gas oxide similar to the following equation: XeF6 + 3H2O -> XeO3 + 6HF.

A noble gas compound with the formula XeF6 is xenon hexafluoride. It is one of xenon's three binary fluorides, along with XeF2 and XeF4. All known are exergonic and stable at normal temperatures. The series' strongest fluorinating agent is XeF6.Water's chemical formula is H2O, which means that each of its molecules consists of two hydrogen atoms and one oxygen atom. In its +6 oxidation state, xenon can form the unstable chemical xenon trioxide(XeO3). It is an extremely potent oxidizing agent that slowly releases oxygen from water, a process that is sped up by sunshine. When it comes into touch with organic materials, it explodes dangerously. It emits xenon and oxygen gas when it explodes.

Thermal energy always moves from higher energy area to lower energy area over a temperature gradient.

What is thermal energy?

Thermal energy is a form of energy by virtue of temperature of a body. As the temperature of a body increase its thermal energy increases. Thermal energy or heat energy transfers though medium and vacuum from higher energy area to lower energy area.

Heat transfer can be through conduction in solids, convection in fluids and by radiation through space. In conduction, the thermal energy easily transfers through a chain of close packed molecules.

In all these mode of heat transfer heat energy is flowing from a hotter region to a colder region.

The sodium is the anode of the cell while the magnesium is the cathode of the cell.

How would the investigation go?

We know that in the cell, we are going to have just about two electrodes in the cell and we would have the cathode and the anode. We have to know that the cathode is the point by which the current would enter the cell and the cathode is the point from which the current would leave the cell.

Having said this, we should know that the investigation would have to take into account the reduction potentials of the magnesium as well as that of the sodium as these can be used in the construction of the cell that is under study here.

The freezing of methane is an exothermic change. What best describes the temperature conditions that are likely to make this a spontaneous change

Answers

The correct answer is option C: Low temperature only, because entropy decreases during freezing.

When a substance changes from a gas to a solid, the entropy (measure of disorder) of the system decreases. This is because the solid has a more ordered structure than the gas. The decrease in entropy is accompanied by a decrease in temperature and an increase in enthalpy (heat content).For a process to be spontaneous, the entropy change must be positive, so the freezing of methane is spontaneous only if the temperature of the surroundings is lower than the temperature of the methane. Thus, the heat released from the exothermic process will be absorbed by the surroundings, the temperature of the methane will decrease, and the entropy of the system increases, driving the process towards completion.

An 80.0-gram sample of water at 10.00C absorbs 1680 Joules of heat energy. What is the final temperature of the water

Answers

108°C is the final temperature of the water after absorption of 1680 Joules of heat energy.

What is temperature?

Temperature is a physical quantity used to measure the average kinetic energy of molecules in matter. This is measured with a thermometer or other device that measures the average kinetic energy of the molecules within the substance. The terms Celsius (°C), Fahrenheit (°F), or Kelvin are commonly used to describe temperature (K). Temperature can affect the physical state of matter.

By rearranging the equation gives:

ΔT = q/mc

Plugging in the given values,

ΔT = 1680/ (80.0 g × 4.184 J/g·C)

= 98°C.

Since the initial temperature was 10°C, the final temperature is:

The solubility of AgCN in a solution containing 1.0M H Ksp of AgCN is 2.2e-12 Ka of HCN is 6.2e-10 is 5.9 x 10^-2M.

Given concentration of H+ (M) = 1.0M

Ksp of AgCN = 2.2e-12

Ka  of HCN = 6.2e-10

AgCN ⇋ Ag+ +CN− ................Ksp

CN − + H+ ⇋ HCN................... 1/Ka​

28.02+8.064+32.07+63.99 = 132.153 g/mol

3. Convert mol to grams
0.750 mol * 132.153 g/ 1 mol = 99.11475 grams ~ 99.1 grams

D.
1. Find the molar mass of all elements and combined

H = 2*1.008 = 2. 016
S = 1 * 32.07 = 32.07
O = 4 * 15.999 = 63.996

Add the products together
2.016 + 32.07 + 63.996 = 98.082 g/mol

2. To find the mass percent, use the equation molar of element divided by molar mass of the products combined in parentheses times 100.
(2.016/98.082) * 100 —> 0.02055423013397 * 100 = 2.05542301339695 %
This can written as 2.055% since 2.016 has 4 significant figures

Notch is a receptor protein displayed on the surface of certain cells in developing fruit fly embryos. Notchs ligand is a membrane-bound protein called Delta that is displayed on the surface of adjacent cells. When Notch is activated by its ligand, the intracellular tail of the Notch protein becomes separated from the rest of the protein. This allows the intracellular tail to move to the cells nucleus and alter the expression of specific genes.Which of the following statements best explains Deltas role in regulating cell communication through the Notch signaling pathway?A. Delta transmits a chemical signal to all the cells of a developing embryo.B. Delta allows the cells of a developing embryo to communicate without making direct contact.C. Delta restricts cell communication to short distances within a developing embryo.D.
