Answer:
There are 3 elements, Sodium, Carbon, and oxygen. There are 2 Sodium atoms 2*2=4, one carbon, and 3 Oxygen so 4+1+3=8 total atoms. one compound CO3
Explanation:
that's all I know
Answer:
8
Explanation:
To solve this question, we just need to put the new number into the equation. If [A] remain constant then that mean [A2]= [A1]. If B doubled, then that mean [B2]= 2[B2]. To find what factor does the rate of reaction increases, we need to divide the first reaction rate with the second. The calculation will be:
rate2/rate1= k[A2][B2]³ / k[A1][B1]³
rate2/rate1= [A1][2B1]³ / [A1][B1]³
rate2/rate1= A1*8B1³ / A1*B1³
rate2/rate1= 8/1= 8
The rate of reaction will be 8 times faster.
Answer :
Heating takes place during the process of Evaporation, Melting, Sublimation.
Cooling takes place during the process of Freezing, Condensation, Deposition.
Explanation :
Heating : It means thermal energy releases.
Cooling : It means thermal energy absorbs.
Evaporation : It is a type of vaporization process in which a liquid changes into gas phase by providing heat.
Melting : It is a process in which a solid changes into liquid phase by providing heat.
Sublimation : It is a process in which a solid changes directly into gas phase without passing through a liquid phase.
Freezing : It is a process in which a liquid transform into a solid phase at low temperature.
Condensation : It is a process in which a water vapor(gas) changes into liquid state at low temperature.
Deposition : It is a process in which a gas transforms directly into a solid phase without passing through a liquid phase.
