If you traded (converted) 15 Skittles for M&Ms, you will have 20 M&Ms

We'll begin by converting 15 Skittles to cookies. This can be obtained as follow:

6 Skittles = 4 Cookies

Therefore,

15 Skittles = (15 Skittles × 4 cookies) / 6 skittles

15 Skittles = 10 cookies

We can convert 10 cookies to M&Ms as follow:

1 Cookies = 2 M&Ms

Therefore,

10 cookies = (10 cookies × 2 M&Ms) / 1 Cookies

10 cookies = 20 M&Ms

Thus, 15 Skittles is equivalent to 20 M&Ms

Answer:

A big star collapsing creates a shock wave that can trigger fusion events in the star's outer shell, which is how I believe the process that took place in stars and supernovae to form the atoms that make up everything on Earth happened. Nucleosynthesis is the process by which these fusion processes produce new atomic nuclei. One of the primary sources of the universe's heavy elements is thought to be supernovae. It is possible to synthesize materials heavier than iron, such as uranium and gold, during a supernova because the star emits enormous amounts of energy and neutrons. All of these components are launched into space during the supernova explosion.

Answer:

Option D.

2Ag⁺(aq) + Ni(s) —> 2Ag(s) + Ni²⁺(aq)

Explanation:

From the question given above:

Ni(s) —> Ni²⁺(aq) + 2e¯

Ag⁺(aq) + e¯ —> Ag(s)

We can obtain the net ionic equation by combining both equation as shown below:

Ag⁺(aq) + e¯ + Ni(s) —> Ag(s) + Ni²⁺(aq) + 2e¯

Next, we shall balance the equation. This can be obtained as follow:

Ag⁺(aq) + e¯ + Ni(s) —> Ag(s) + Ni²⁺(aq) + 2e¯

There are 2 atoms of e¯ on the right side and 1 atom on the left side. It can be balance by putting 2 in front of e¯ as shown below:

Ag⁺(aq) + 2e¯ + Ni(s) —> Ag(s) + Ni²⁺(aq) + 2e¯

Next, we shall balance the charge on both sides. This is illustrated below:

TOTAL charge on the left = +1 + (–2)

= 1 – 2

= –1

TOTAL charge on the right side = +2 + (–2)

= 2 – 2

= 0

Thus, to balance the charge, put 2 in front of Ag⁺ as shown below:

2Ag⁺(aq) + 2e¯ + Ni(s) —> Ag(s) + Ni²⁺(aq) + 2e¯

There are 2 atoms of Ag on the left side and 1 atom on the right side. It can be balance by putting 2 in front of Ag as shown below:

2Ag⁺(aq) + 2e¯ + Ni(s) —> 2Ag(s) + Ni²⁺(aq) + 2e¯

Next, cancel out 2e¯ from both side to obtain the net ionic equation. Thus, we have:

2Ag⁺(aq) + Ni(s) —> 2Ag(s) + Ni²⁺(aq)

Answer:

Heating water until it boils. The water particles would gain thermal energy from the heat source and there would be an increase in the kinetic energy between the water particles. During this stage, the temperature of the water particles remains the same as the thermal energy is used to break the strong bonds of attraction between the water particles so that they can be further apart and transition from the liquid state to the gas state.

Consider a solution containing 10−5 M H2S(aq) and a constant dissolved oxygen concentration of 0.25 mM (8.0 mg/L). If the given reaction is the only way that 100 temperature.

Temperature is a numerical expression of how hot (or energetic) stuff or radiation is.

There are three different types of temperature scales: those, like the SI scale, that are defined in terms of the average translational kinetic energy per freely moving microscopic particle, like an atom, molecule, or electron, in a body; those that only depend on strictly macroscopic properties and thermodynamic principles, like Kelvin's original definition; and those that are defined by practical empirical properties of particulates rather than by theoretical principles.

Using a thermometer, one can gauge temperature. It is calibrated using different temperature scales, each of which historically defined itself using a different set of reference points and thermometric materials.

Answer:

The products are SnPO4 and LiC2H3O2

Explanation:

The reactants are LiPO4 + Sn(C2H3O2)2

This is a double replacement reaction

So what you do is switch the elements the other way around.

To do that, all you have to do switch Sn with PO4 since Sn is a cation and PO4 is an anion.

Then you switch Li with C2H3O2 because Li is a cation and C2H3O2 is an anion.

After that, check the charges. PO4 has -3 charge

So just leave Sn the way it is without a subscript.

In word form, the product would be Tin(III) Phosphate

C2H3O2 has a -1 charge Li has a +1 charge

So leave both of them the way it is without any subscripts.

In word form, the product would be Lithium Acetate

Explanation:

Divergent: When two plates are diverging from each other, meaning that the two plates are moving away from each other. Events that may occur include ridges or rifts.

Convergent: When two plates are moving towards each other.

If a continental plate and an oceanic plate are converging, the oceanic plate would slide underneath the continental plate since it is thinner. This would result in subduction, which means that part of the oceanic plate would hang underneath the continental plate, where magma can melt the hanging part.

If two continental plates are converging, the crash would result in mountains or volcanic activity. Magma could rise and rush from the crack. There would be a bump in these tectonic plates.

Transform: When two plates are sliding past each other. Earthquakes can occur when the plates are sliding. When an oceanic plate is involved, the movement of the plates could cause a tsunami as well. The water above the transform fault could rise, and grow bigger and bigger. The 2011 Japan Tsunami is a good example of this.

H=12×1 = 12

O=6×16=96

Molar mass=72+12+96

Molar mass=170

Answer:

180

Explanation:

C = 12

H = 1

O = 16

The molar mass of the glucose is

⇒ 12 x 6 + 1 x 12 + 16 x 6

⇒ 72 + 12 + 96

Aristotle laid the philosophical groundwork for all subsequent discussions of elements, pure substances, and chemical combinations.

The nature of substances and their transformations were the main topics of Aristotle's theories, just like in contemporary chemistry. In On Generation and Corruption (De Generatione et Corruptione), Meteorology, and portions of Physics and On the Heavens, he provided the first systematic treatments of chemical theory (De Caelo).

Although he believed that some of them might be made of a single, pure component, Aristotle realized that the majority of common, tangible things are composed of several different substances. In order to identify a single substance, he needed to provide a purity standard. His standard was the homoeomerism of pure substances, which means that they are made up of similar components at all levels.

Answer:

The correct answer is -1946.89 j/K.

Explanation:

The reaction is:

2H2O (l) ⇔ 2H2 (g) + O2(g)

First there is a need to find dHfrxn = dHf(Products) - dHf(reactants)

With the help of standard thermodynamic table, the values of dHf can be obtained,

dHf(H2O) = -285.8 kJ/mol

dHf(H2) = 0 kJ/mol

dHf(O2) = 0 kJ/mol

dHrxn = 2 × dHf (H2) + dHf(O2) - 2 × dHf(H2O)

= 2 × 0 + 0-2 × (-285.8) kJ = +571.6 kJ

This value is for 2 moles of H2O, for 2.03 moles of H2O, the value will be,  

dHrxn = +571.6 kJ/2 mol × 2.03 mol

= 580.174 kJ

The given temperature is 298 K.  

So, the value of dSsurr = -dHrxn/T  

= -580.174kJ/298 K

= -580174 j/298K

= -1946.89 j/K

Molarity = 0.24 M

Explanation:

Given data:

Number of moles of Mg(NO₃)₂ = 0.181 mol

Volume of solution = 0.750 L

Molarity of solution = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

by putting values,

Molarity = 0.181 mol / 0.750 L

Molarity = 0.24 M

Multiply the no. of moles with Avogadro's constant which is 6.02*10^23
