Reactants are what is changed in the chemical reaction. They go before the arrow when you wrote the equation. Products are what is formed when the chemical reaction occurs. Products always contain the same elements as the reactants, but they might be rearranged because of the reaction. In this picture, you can see that the reactants go before the arrow, and the products go after.

<h3>What I think is : The protons are present at the centre of the atom with rotating electrons around it so when it is rubbed by fur the electrons get passed from the ebonite rod to the fur leaving the rod negatively charged</h3>

Argon is the third most common gas found in the air we breathe. The air we breathe has approximately 78% nitrogen and 21 % oxygen. The third more abundant gas in the air we breathe is Argon. It is available in a very small quantity in the air that we breathe.
The percentage of the gas argon is about 0.9% in the air
that we breathe. There are several other gases also present in the air that we
breathe, but they are found mostly in negligible amounts.
Answer:
c = 5505263.16 J/g.°C
Explanation:
Given data:
Mass of ring = 12 mg (12/1000 = 0.012 g)
Calories used = 30.0 cal (30.0 ×4184 = 125520 J)
Temperature increases = 1.9°C
Specific heat of ring = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
125520 J = 0.012 g×c ×1.9°C
125520 J = 0.0228 g.°C ×c
c = 125520 J / 0.0228 g.°C
c = 5505263.16 J/g.°C
