Answer:
Explanation:
exothermic reactions involve release of heat whereas endothermic reaction involve absorption of heat.
The answer choice is going to be B.
Answer:
its 0.163 g
Explanation:
From the total pressure and the vapour pressure of water we can calculate the partial pressure of O2
PO 2 =P t −P H 2 O
= 760 − 22.4
= 737.6 mmHg
From the ideal gas equation we write.
W= RT/PVM = (0.0821Latm/Kmol)(273+24)K(0.974atm)(0.128L)(32.0g/mol/) =0.163g
Answer:
iron, graphite,NaCl solution etc are some examples of good conductor of electricity
Opposing reactions are constantly occurring at equal rates
favoring the formation if fewer miles if gaseous products
