Explanation:When the stove turns on the skillet will become very hot because of the conduction of heat transferring from the stove to the skillet.
Answer : Option 1) nuclei of
and nuclei of
only.
Explanation : Radiation is spontaneously emitted from nuclei of
because this isotope of hydrogen is highly radioactive as compared to other isotopes of hydrogen namely; nuclei of
and nuclei of
.
They have much stable nucleus as compared to nuclei of
.
The more it is unstable the more radiations will be emitted from its nucleus.
Answer:
26 grams of D will be produced.
Explanation:
The reaction is given by:
A + B -----> C + D
Mass of A reacted = 21 g
Mass of B reacted = 22 g
Mass of C formed = 17 g
Mass of D formed = m =?
According to law of conservation of mass, the total mass of the reactants used is equal to the total mass of the product formed.
Then:
mass of A reacted + mass of B reacted = mass of C formed + mass of D formed
21 + 22 = 17 + m
m = 26 g
S2F6, is the correct answer I believe!
