Use the PhET simulation to identify what happens to the concentrations of a dilute Drink mix mixture or a pure Drink mix solution for the following scenarios. A pure Drink mix solution can be obtained by draining all the mixture, then adding Drink mix to the container as a Solution (radio button in the upper right area of the simulation). Note that the Concentration meter can be placed toward the bottom of the container or in the stream of the Drink mix. Drag the appropriate items to their respective bins.

Answer:

Explanation:

The formula is density = mass÷volume

Values given are:

mass = 5.910g  and

diameter = 10.0 mm = 1cm

so, we need to find the volume first.

Volume of a sphere is (4/3)πr³

thus, V = 4.189 cm³

Density = mass ÷ volume

density = 5.910 ÷ 4.189

= 1.411 g/cm³

Explanation: Chemical changes  cause a substance to change into an entirely substance with a new chemical formula. And chemical changes are also known as chemical reaction.

This problem is providing information about the states of matter and a given diagram showing a molecular arrangement it has. Thus, we can start off by analyzing the attached file, which shows molecular arrangements and movements each state exhibits.

Solids are quite organized so that they are able to form molecular networks in which molecules vibrate but do not displace anywhere. Liquid molecules are close enough to have small movements and vibrations but are not able to form any organized network.

Gases, however, exhibit no molecular organization but large movements inside the container whose walls the gas constantly crash against. Plasma do not have any order neither yet it contains ions.

In such a way, since the given diagram do not have any apparent order or ion, we infer this is about a gas that moves into the container and crash against its walls.

Answer:

[tex]V_2=35.68\ L[/tex]

Explanation:

Initial volume, V₁ = 300 L

Temperature, T₁ = 227°C

New temperature, T₂ =  27°C

We need to find the volume of gas occupied when the temperature is 27°C.

It is based on Charle's law. A/c to Charle's law,

[tex]V\propto T[/tex] (at constant pressure)

[tex]\dfrac{V_1}{V_2}=\dfrac{T_1}{T_2}\\\\V_2=\dfrac{V_1T_2}{T_1}\\\\V_2=\dfrac{300\times 27}{227}\\\\V_2=35.68\ L[/tex]

Hence, the new volume is 35.68 L.

Protons

Each element has an atomic number. The atomic numbers are listed along with the names and symbols of the elements on the inside cover of the text. The atomic number equals the charge on the nucleus. It therefore also equals the number of protons in the nucleus and also equals numerically the number of electrons in the neutral atom. The atomic number has the symbol Z.

Different elements have different atomic numbers; therefore, atoms of different elements contain different numbers of protons (and electrons). Oxygen has the atomic number 8; its atoms contain 8 protons and 8 electrons. Uranium has the atomic number 92; its atoms contain 92 protons and 92 electrons.

The relationship between atomic number and the number of protons or electrons can be stated as follows:

Atomic number= number of protons per atom= number of electrons per neutral atom

B. Mass Number Equals Protons plus Neutrons

Each atom also has a mass number, denoted by the symbol A. The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in any atom is its mass number minus its atomic number.

Number of neutrons = mass number - atomic number

or

Mass number = number of protons + number of neutrons

The atomic number and the mass number of an atom of an element can be shown by writing, in front of the symbol of the element, the mass number as a superscript and the atomic number as a subscript:

mass number

atomic numberSymbol of elementorA

ZX

For example, an atom of gold (symbol Au), with an atomic number 79 and mass number of 196 is denoted as:

196

79Au

C. Isotopes

Although all atoms of a given element must have the same atomic number, they need not all have the same mass number. For example, some atoms of carbon (atomic number 6) have a mass number of 12, others have a mass number of 13, and still others have a mass number of 14. These different kinds of the same element are called isotopes. Isotopes are atoms that have the same atomic number (and are therefore of the same element) but different mass numbers. The composition of atoms of the naturally occurring isotopes of carbon are shown in Table 4.2.

TABLE 4.2 The naturally occurring isotopes of carbonIsotopeProtonsElectronsNeutrons12

6C66613

6C66714

6C668

The various isotopes of an element can be designated by using superscripts and subscripts to show the mass number and the atomic number. They can also be identified by the name of the element with the mass number of the particular isotope. For example, as an alternative to

12

6C,13

6C,and14

6C

we can write carbon-12, carbon-13, and carbon-14.

About 350 isotopes occur naturally on Earth, and another 1500 have been produced artificially. The isotopes of a given element are by no means equally abundant. For example, 98.89% of all carbon occurring in nature is carbon-12, 1.11% is carbon-13, and only a trace is carbon-14. Some elements have only one naturally occurring isotope. Table 4.3 lists the naturally occurring isotopes of several common elements, along with their relative abundance.

Explanation:

Fossilized marine creatures found at the top of the Himalayan Mountains provide evidence for a scientific theory of plate tectonics. Therefore, option (D) is correct.

Plate tectonics can be explained as the Earth's lithosphere being made of a large number of tectonic plates that have been slowly moving since about 3.4 billion years ago.

The lithosphere is broken into 7 or 8 major plates and many minor plates or "platelets". These plates meet, and their relative motion evaluates the kind of plate boundary: convergent, transform, or divergent.

Mountain-building, Earthquakes, volcanic activity, and oceanic trench formation take place along these plate boundaries. The relative annual movement of the plates ranges from 0 to 10 cm.

Tectonic plates are comprised of the oceanic and the thicker continental lithosphere. The process of subduction which is actually one plate moving under another carries the edge of the lower plate down into the mantle along convergent boundaries.

Pebbles, Shells, and marine fossils found in the limestone beds of the tallest Himalayas Mountains give evidence of the theory of plate tectonics.

Explanation:

The given redox reaction can be balanced in acidic medium as follows:

[tex]\rm 2 Br^{-} + HNO_{2} + H^{+} \rightarrow Br_{2} +NO + H_{2}O[/tex]

A reaction involving both oxidation and reduction is called redox reaction. One species is getting oxidized here whereas another species reduces. The substance which is oxidized  is called oxidant and the reduced species is called reductant.

In the given reaction of bromine gas with nitrous acid, bromine oxidizes from -1 to zero whereas nitrogen reduces from +3 to +2. The reaction can be occurred in acidic medium.

The redox reaction written in acidic medium involves H+ and water properly added to either sides. The balanced redox reaction of the given one in the acidic medium is thus as written above.
