3. What mass of water vapor condenses if 435 kJ of heat are released in the process? a a 10.79 b 982 g C 1.30 x 10 g d 1939​

Answers

Mass of water vapor = 193 g

Further explanation

Given

435 kJ of heat are released

Required

mass of water vapor

Solution

The heat to change the phase can be formulated :

Q = mLf (melting/freezing)

Q = mLv (vaporization/condensation)

Lv for water = 2256 kJ/kg or 2256 J/g or 40.7 kJ/mol

So the mass of water vapor :

[tex]\tt m=\dfrac{Q}{Lv}\\\\m=\dfrac{435000~J}{2256~J/g}\\\\m=192.8\approx 193~g[/tex]

What is the molecule that formed between B and F?

Answers

Answer:

BF3

Explanation:

For this question, you need to use the number of valence electrons present in each element. Boron is in group 3/13 on the periodic table so you know it has 3 valence electrons while Fluorine is in group 7/17 so it has 7 valence electrons. These elements are both covalent so they will share electrons. All elements in the first three rows want to reach either have 8 valence electrons or zero valence electrons depending on whichever is easier. When B and F interact each Fluorine will only want to take one electron, but Boron wants to get rid of all 3 electrons, so it will bond with 3 Fluorine to get rid of all its valence electrons.

Nuclear fusion reactions release more energy than fission reactions while also generating less waste. However, nuclear fusion reactors are not currently used to generate electricity.

What is the main reason for this?

Answers

Nuclear fusion reactions release high energy and required tremendous temperature of nuclear reactors is the main reason for not used to generate electricity.

What are nuclear reactions?

Nuclear reactions are those reactions which are taking place in the nucleus of any unstable atom and produces energy.

As in the question it is given that nuclear fusion reactions releases more energy and less wastage, but this energy are releases in the tremendous amount which can be proved harmful for the environment and the humans. To carry out this reaction we have to maintain the very high temperature of nuclear reactors of about 6 times greater than sun's temperature, which is not possible manually.

Hence, high temperature of nuclear reactors and high amount of energy released is the main reason.

Scientists use the chemical and physical properties of matter to differentiate substances. Which of the following is a chemical property?
(A) A starch sample turns blue when introduced to iodine
(B) Gold's property of malleability allow it to be shaped into a ring.
(C) Salts exhibit electrical conductivity.
(D) A metal is identified by its density.

Answers

Answer:

a.) A starch sample turns blue when introduced to iodine

Explanation:

A is a chemical change whereas the other answers would be physical changes.

The chemical property has been the turning of the iodine blue with starch introduction. Thus, option A is correct.

The substance properties can be differentiated as Physical properties and chemical properties. Physical properties can be defined as the properties that do not lead to the change in the chemical composition of the compound, For example, electrical conductivity, malleability, density, etc.

The properties of the compound that have been led to the change in the chemical composition of the compound have been termed chemical properties. For example. burning, reduction, etc.

Since the starch sample has been reacted with iodine there has been a chemical change that leads to the product of blue color. Thus, the starch turning iodine blue has been the chemical property. Thus, option A is correct.

Answer:

Most earthquakes occur along the edge of the oceanic and continental plates. The belt exists along boundaries of tectonic plates, where plates of mostly oceanic crust are sinking beneath another plate.

Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. As the plates move, they spread apart, collide, or slide past each other. Sixty percent of all active volcanoes occur at the boundaries between tectonic plates.
