What type of reaction does each of the following equations represent?
A. Single replacement
B. Double replacement
C. Decomposition
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)

f is the force
m is the mass
From the question we have
[tex]a = \frac{8}{2} \\ [/tex]

Write one paragraph explaining what you have learned so far about Kinetic and Potential Energy.
(will give brainliest)
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.
A tank containing oxygen, carbon dioxide, and nitrogen gases has a total pressure of 6.7
atm. If the O2 has a pressure of 3.0 atm and the carbon dioxide has a pressure of 1.2
what is the partial pressure of the nitrogen gas?
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

A 10g sample of Fe reacts with O to form 18.2g of FeO. How many grams of O reacted?
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

How many moles of Mg(OH)2 will react with 2.5 mol HCI?
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

What is the speed of an object that covers 10 miles in 5 hours?
a. 5 mph
b. 15 mph
c. 2 mph
d. 50 mph
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.
What is speed?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.

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.

Someone please help will mark as brainliest please answer all of the questions
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
