The ph of solution will be 2.865 which comes in the catogery of weak acid
Answer:
The kinetic energy of the two curling stones is 320 J
Explanation:
Given;
mass of the first curling stone, m₁ = 20 kg
velocity of the first curling stone, v₁ = 4 m/s
velocity of the second curling stone, v₂ = - 4m/s
assuming the second curling stone to have equal mass with the first stone = 20 kg
The kinetic energy of the first curling stone is given by;
K.E₁ = ¹/₂m₁v₁²
K.E₁ = ¹/₂(20)(4)²
K.E₁ = 160 J
The kinetic energy of the second stone is given by;
K.E₂ = ¹/₂m₂v₂²
K.E₂ = ¹/₂ (20) (-4)²
K.E₂ = 160 J
Thus, the kinetic energy of the two curling stones is given by;
K.E = K.E₁ + K.E₂
K.E = 160 J + 160 J
K.E = 320 J
Therefore, the kinetic energy of the two curling stones is 320 J

The answer to your question is below
Explanation:
Alpha decay occurs when a radioactive atm emits an alpha particle (Helium atom).
a) ²⁵⁶Ra ⇒ ²⁵²₈₄ Po + ⁴₂He
b) ²¹⁹Rn ⇒ ²¹⁵₈₂Pb + ⁴₂He
c) ²¹¹Po ⇒ ²⁰⁷₈₀Hg + ⁴₂Hg
d) ²¹⁰Pb ⇒ ²⁰⁶₇₈Pt + ⁴₂Hg
e) ²³⁸U ⇒ ²³⁴₈₈U + ⁴₂Hg
Event 1 is an example of a chemical reaction.
<u>Explanation:</u>
Whenever if two solutions are mixed, then if there is any color change, or evolution of any vapors, bubbles or gas formation or if there is any formation of a color or white precipitate confirms that the occurrence of a chemical reaction.
If nothing happens said above then it is said that there is no chemical reaction occurs.
Here in the event 1 a clear liquid in one beaker poured into clear liquid in beaker 2 then there is a formation of orange liquid, which means there is a formation of a new colored liquid confirms that the chemical reaction occurred.
