When a particle and its antiparticle collide they are converted to energy.
What is collide?A colloid would be a mixture in which a component made up of insoluble particles that are scattered at a microscopic scale is suspended within another component.
What is energy?In order to accomplish work and to produce heat as well as light, energy must be supplied to a body or even to a physical system. Energy would be the quantitative attribute that does this. Energy would be transformed in form but cannot be created and destroyed, according to the rule of conservation of energy.
Annihilation occurs when a particle collides including its anti-particle. The particle and its antiparticle's whole mass are transformed back into energy to produce two gamma-ray photons. You won't find antiparticles in everyday stuff since they typically barely last for a tiny amount of time until annihilation takes place.
Therefore, the correct answer will be option (c).

If you put 100g of NaOH in cube form and 200g of NaOH in powered form which will react with HCl at a faster rate? Explain why
Answer:
200g of NaOH in powered form will react with HCl at a faster rate
Explanation:
200g of NaOH in powered form will react with HCl at a faster rate because it is in powdered form and it will have high surface area to volume ration and hence high reactivity and rate of reaction as compared to the cube NaOH.
How many atoms does 9.3 moles of Mo represent?
Answer:
5.60 × 10²⁴ Mo atomsExplanation:
The number of atoms can be found by using the formula
N = n × Lwhere n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
We have
N = 9.3 × 6.02 × 10²³
We have the final answer as

The pressure in a car tire is 178 kPa at 37°C. After a long drive, the pressure is 275 kPa. What is
the new temp of the air in the tire, assuming the volume is constant?
Answer:
T₂ = 478.93 K
Explanation:
Given that,
Initial pressure, P₁ = 178 kPa
Initial temperature, T₁ = 37°C = 310 K
Final pressure, P₂ = 275 kPa
We need to find the new temp of the air in the tire, assuming the volume is constant. We know that,
[tex]\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}\\\\T_2=\dfrac{P_2T_1}{P_1}\\\\T_2=\dfrac{275\times 310}{178}\\\\T_2=478.93 K[/tex]
So, the new temperature is equal to 478.93 K.

Evidence of Earth’s plate tectonic activity is most obvious after an earthquake. Which explanation best describes this plate tectonic movement?
A: Earth’s plates stress one another. However, when an earthquake occurs, plate movement is due to an unbalanced force on the plates.
B: Earth’s plates are moving fast. However, the force of friction slows their movement.
C: The force of gravity causes the floating plates to move up and down. The plate movement sometimes results in earthquakes.
D: Earth’s plates continually place stress on one another. However, the force is balanced during an earthquake.
Answer:a
Explanation:bc
Plates on Earth are moving quickly. Yet, friction causes them to travel more slowly. So, the correct options are B and C.
What are tectonic plates?Tectonic plates are enormous fragments of the upper mantle and crust of the Earth. They are composed of both continental and oceanic crust. Earthquakes occur around mid-ocean ridges and the large faults which mark the edges of the plates.
The Earth's plates are shifting swiftly. Nevertheless, friction slows their movement. Gravity causes the floating plates to rise and fall. On occasion, the movement of tectonic plates results in earthquakes.
When compared to the Earth's mantle, the plates behave like solid, unyielding shells. The lithosphere is the name given to this thick outer layer.
Thus, the correct options are B and C.

If 0.583 g of ammonia (NH3) is dissolved to make 250 mL of solution, what is the molarity?
Answer:
0.137 M NH3
Explanation:
First divide the mass of NH3 by the molar mass of NH3, and then divide by the volume to get molarity.
0.583 g / 17.031 g/mol = 0.0342 mol NH3
0.0342 mol NH3 / 0.250 L = 0.137 M NH3

How many moles of O₂ are needed to burn 2.5 moles of CH₃OH?
Answer:
3.75 moles
Explanation:
The chemical equation is 2CH₃OH + 3O₂ -> 2CO₂ + 4H₂O
2 moles of CH₃OH are burned by 3 moles of O₂
For 2.5 moles of CH₃OH are burned by x moles of O₂
Let's solve for x :
2*x=2.5*3 => 2*x=7.5 => x=3.75 moles of O₂ are needed to burn 2.5 moles of CH₃OH

Using an analogy of a water balloon, describe the function of the bladder.
Answer:
A bladder is like a balloon, because it holds urine, just like a balloon holds air. The urethra's function is to excrete urine from the human body.
Explanation:
A bladder and a balloon are similar, because it is the bladder which clasp urine, whereas a balloon clench air. The role of urethra is to eliminate urine from our human body.
What is bladder?The hollow organ which is in triangle shape and found in the lower abdomen just like a balloon is defined as the bladder. The urinary bladder is also known as a temporary reservoir of urine. Urine is reserved in the urinary bladder till it is removed out through the urethra.
As a result of the contraction of the wall of the urinary bladder, urine is eliminated from the body from time to time. The urine contains waste and extra fluid left over the body which has to be eliminated.
The bladder resembles the water balloon in that it holds urine in the similar way as the water balloon clench water. The water balloon pops when the amount of water exceeds than it can hold.
Thus the function of bladder and water balloon are found to be same.
