What is the product of the synthesis reaction between calcium and iodine?

Answers

Answer 1

Answer:

The product of the synthesis reaction is CaI.

Explanation:

In chemistry, chemical equations are the representation of chemical reactions between elements, compounds, substances, or molecules.

They are written using element symbols (and sometimes including their current state of matter).

Therefore, if we wanted to show the reaction of sodium and chlorine to make sodium chloride, or table salt, we would illustrate it as such:

[tex]\bullet \ \text{Na + Cl} \rightarrow \text{NaCl}[/tex]

A synthesis reaction in chemistry is the combination of two or more elements, compounds, molecules, or substances to make one compound, molecule, or substance.

The parent equation for a synthesis reaction is:

[tex]\bullet \ \text{A + B}\rightarrow \text{AB}[/tex]

Therefore, we need to find out what the element symbols are for both calcium and iodine.

If we reference a periodic table, we will see that calcium is atomic number 20 and has the symbol Ca.

Additionally, when we locate iodine, we will see that it is atomic number 53 and has the atomic symbol I.

Now, we just need to create the reaction equation.

[tex]\text{Ca + I}\rightarrow \text{?}[/tex]

We know that we are dealing with a synthesis reaction, or a combination, so the elements will combine to make one substance.

With this information, we can make an equation:

[tex]\text{Ca + I} \rightarrow \text{CaI}[/tex]

Therefore, the product of the synthesis reaction is CaI.

Note: Please note that "I" is an uppercase i.

3. Does the siren of a moving police car seem to change pitch to the
police officers inside the car? Why or why not?

Answers

Answer:

As the police car moves towards them, the pitch of the police car's siren goes up because the sound waves get closer together in front of the police car. When the police car moves away from the person, the pitch goes down because the waves spread out behind the police and that makes the frequency go down.

How much heat is required to raise the temperature of a 6.21 g sample of iron from 25.0 oC to 79.8 oC?

Answers

Answer:

151.1J

Explanation:

Given parameters:

Mass of iron  = 6.21g

Initial temperature of iron  = 25°C

Final temperature of iron  = 79.8°C

Unknown:

Amount of heat = ?

Solution:

The amount of heat require to cause this temperature can be determined using the expression below;

    H  = m c (T₂ - T₁)

H is the amount of heat

m is the mass

c is the specific heat capacity

T is the temperature

    Specific heat capacity of iron 0.444J/g°C

Insert the parameters and solve;

     H  = 6.21 x 0.444 x (79.8 - 25)

     H   = 151.1J

Using the quantum numbers of the identified electrons to derive the electron configuration ( the representation of the distribution of electrons in the orbit of  an atom ) electron configuration of electrons can be calculated using the formula :2n².

where n = orbit number and the various energy levels are represented as 1,2,3,4... while shells of the an atom is written as K,L,M,N

hence the electron configuration of the electrons identified by the quantum numbers are as written above.

Which models of the atom does the experimental evidence from Bohr's hydrogen experiment support? Explain why these models are compatible with the experimental results.

The models are Daltons, Thompsons, and Rutherfords

Answers

Answer:

Rutherfords

Explanation:

The model of the atom supported by Bohr's hydrogen experiment is the Rutherford's model of the atom.

Rutherford through his experiment on gold foil suggested the atomic model of the atom. The model posits that an atom has a small positively charged center(nucleus) where nearly all the mass is concentrated.

Surrounding the nucleus is the large space containing electrons. In the Bohr's model of the atom, he suggested that the extranuclear space of the atom is made up of electrons in specific spherical orbits around the nucleus.

In this example we will start the Carbon Dioxide out at a temperature of -20oC and 1 atm of pressure. If the pressure was raised to 100 atm of pressure while still staying at -20oC, what phases would the Carbon Dioxide change between?

Answers

If you mark those points on the phase diagram it appears to be moving from vapor to liquid. If you can’t see how I determined that please let me know and I can further explain.

Vapor to liquid is the same as saying gas to liquid, which I believe to be the correct answer.

Calculate how much Carbon Dioxide IN GRAMS needs to be absorbed to
release 500g of oxygen during photosynthesis.

Answers

Answer:

687.5 g of CO2

Explanation:

We'll begin by writing the balanced equation for photosynthesis. This is illustrated below:

6CO2 + 6H2O —> C6H12O6 + 6O2

Next, we shall determine the mass of CO2 absorbed and the mass of O2 released from the balanced equation. This is illustrated below:

Mass of CO2 = 12 + (2 × 16) = 12 + 32

= 44 g/mol

Mass of CO2 from the balanced equation = 6 × 44 = 264 g

Molar mass of O2 = 2 × 16 = 32 g/mol

Mass of O2 from the balanced equation = 6 × 32 = 192 g

Summary:

From the balanced equation above,

264 g of CO2 were absorbed to release 192 g of O2.

Finally, we shall determine the mass of CO2 absorbed to release 500 g of O2. This can be obtained as follow:

From the balanced equation above,

264 g of CO2 were absorbed to release 192 g of O2.

Therefore, Xg of CO2 will be absorbed to release 500 g of O2 i.e

Xg of CO2 = (264 × 500)/192

Xg of CO2 = 687.5 g

Thus, 687.5 g of CO2 will be absorbed to release 500 g of O2.
