The answer is C. 2, 1, 2, 1
This way both sides of the reaction have the same amount of atoms of each element:
Na = 2 atoms
Cl = 2 atoms
Ca = 1 atom
F = 2 atoms
following the law of conservation of mass which says the mass remains constant, it can't be added or removed
Answer:
R = 19.36 ohms
Explanation:
Given that,
The power of an electric motor, P = 2500 Watts
The voltage of the circuit, V = 220 V
We need to find the resistance of the motor. We can find it as follows :
So, the resistance of the motor is 19.36 ohms.
Explanation:
Specific heat of a substance is defined as the amount of heat that is required to raise the temperature of one mole or mass of a substance by 1°C.
The total amount of heat of a substance is the amount of heat required to raise the temperature of the given mass of the substance by 1°C.
Specific heat is an intensive property and does not depend on the amount of matter that is present within a substance.
Total amount of heat is an extensive property of matter and it is predicated on the amount of matter present.
and C. taste, odor, and texture
