Explanation:

%C = 27.3%

%O=72.7%

Proust states the Comparative Law that compounds are formed from elements with the same Mass Comparison, so that compounds have a fixed composition of elements

The empirical formula is the mole ratio of compounds forming elements.

MW CO₂ : 44 g/mol

Ar C = 12 g/mol

Ar O = 16

[tex]\tt \dfrac{12}{44}\times 100\%=27.3\%[/tex]

[tex]\tt \dfrac{2.16}{44}\times 100\%=72.7\%[/tex]

Answer:

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

[tex]a = \frac{f}{m} \\ [/tex]

f is the force

m is the mass

From the question we have

[tex]a = \frac{8}{2} \\ [/tex]

Answer:

1. Aluminum oxide

2. Sodium chloride

3. Magnesium oxide

4. Calcium Chloride

Explanation:

Ionic compounds with only 2 elements all end with "ide" Use the full name of the element listed first and the second element with ide. Ex: Chlorine would become chloride.

Answer:

Explanation:

1. Al2O3 = Aluminum Oxide

2. NaCl  =  Sodium Chloride

3. MgO  =  Magnesium Oxide

4. CaCl2  = Calcium Chloride

Answer:

1.25mole of Mg(OH)₂

Explanation:

The reaction is between Mg(OH)₂ and HCl, this is a neutralization reaction between an acid and a base.

         Mg(OH)₂   +   2HCl   →   MgCl₂   + 2H₂O

The balanced reaction equation is given above.

           2 mole of HCl reacts with 1 mole of Mg(OH)₂

So,       2.5mole of HCl will react with [tex]\frac{2.5}{2}[/tex]  = 1.25mole of Mg(OH)₂

The number of moles of Mg(OH)₂ is given as 1.25mol

Answer:

P(N₂) = 2.5 atm

Explanation:

Given data:

Total pressure of gasses = 6.7 atm

Partial pressure of O₂ = 3.0 atm

Partial pressure of CO₂ = 1.2 atm

Partial pressure of N₂ = ?

Solution;

According to Dalton law of partial pressure,

The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.

Mathematical expression:

P(total) = P₁ + P₂ + P₃+ ............+Pₙ

Now we will solve this  problem by using this law.

P(total) = P(O₂)  + P(CO₂) + P(N₂)

6.7 atm = 3.0 atm + 1.2 atm + P(N₂)

6.7 atm = 4.2 atm + P(N₂)

P(N₂) = 6.7 atm - 4.2 atm

P(N₂) = 2.5 atm

Answer:

1.The main difference between SPECT and PET scans is the type of radiotracers used. While SPECT scans measure gamma rays, the decay of the radiotracers used with PET scans produce small particles called positrons. ... These react with electrons in the body and when these two particles combine they annihilate each other.

2 .A single photon emission computed tomography (SPECT) scan is an imaging test that shows how blood flows to tissues and organs. It may be used to help diagnose seizures, stroke, stress fractures, infections, and tumors in the spine.

3.Uses for PET scan include checking brain function; diagnosing cancer, heart problems, and brain disorders; examining blood flow to the heart; and determining spread of cancer and response to therapy. The use of PET scans may help doctors more accurately detect the presence and location of cancer cells.

4.Stress-only SPECT protocols resulting in lower dosimetry and less time in the imaging laboratory may be appropriate for many patients. PET perfusion imaging offers indisputably better images that are characterized by higher resolution, better attenuation correction, less scatter, and better contrast

Answer:

c

Explanation:

protons are the atomic number which define an element

Answer: Energy stored in an object due to its position is Potential Energy. The energy that a moving object has due to its motion is Kinetic Energy. All forms of kinetic energy are the result of a previous state of potential energy. For example, the stored chemical potential energy of a battery converts to electrical kinetic energy to transport electricity to a light bulb, which radiates thermal kinetic energy. Potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.

The reaction would shift to favor the side with the most moles of gas.

Answer:

2 miles per hour.

Explanation:

10/5=2

To solve this we must be knowing each and every concept related to speed  and its calculations. Therefore, the correct option is option C.

Speed may be defined as the distance traveled by an item in the amount of time it requires to travel that distance. In other words, it measures how rapidly an item travels but does not provide direction.

The Scientific unit system is most typically used to express speed. Speed is determined in metres per second, or m/s, since distance is recorded in metres while time is recorded in seconds.

Mathematically,  

speed= distance/ time

distance= 10 miles

time= 5 hours

substituting all the given values in the above equation, we get

speed=10/5

on calculations, we get

speed = 2 mph

Therefore, the correct option is option C.

Answer: Dinitrogen pentoxide

Explanation:

Answer:

Dinitrogen Pentoxide

Explanation:

In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. The researcher can operationalize (i.e. define) the variables being studied so they can be objectivity measured.

Answer:

Mass of O = 8.2 gram

Explanation:

Given:

Mass of Fe = 10 g

Total volume = 18.2 g

Find:

Mass of O

Computation:

Using Conservation of total mass

Total volume = Mass of O + Mass of Fe

18.2 = Mass of O + 10

Mass of O = 8.2 gram

Answer:

Option C. Decomposition

Explanation:

To know which option is correct, it is important we know what is a single displacement reaction, double displacement reaction and decomposition reaction.

A Single displacement reaction can be defined as a reaction in which a single element is replaced by another element in a compound.

A double displacement reaction is a reaction involving the exchange of ions of two parts of ionic compounds to form two different compounds.

A decomposition reaction is a reaction in which a compound splits into two or more simpler compound or element.

Bearing the above definitions in mind and considering the question given above, we can conclude that the reaction given in the question above is a decomposition reaction since the compound (NH₄OH) splits into two different compound (NH₃ and H₂O)
