Answer: With power and energy, power is units of energy divided by time. The same difference as distance and velocity. The units of power are watts, the units of energy are joules.
Explanation:
It is exothermic. Exothermic reaction is a reaction that gives out heat and energy. Sodium is a highly reactive metal that is found in group 1 in the periodic table. We all know that all group 1 elements(alkali metals) are usually stored in inert liquid like oil to prevent contact with air and water so as to prevent an explosion. An explosion is a form of a exothermic reaction since it gives out heat and light. Hence, the reaction between Na and water is an exothermic reaction.
Have a nice day ahead.
The ideal gas law may be written as
where
p = pressure
ρ =density
T = temperature
M = molar mass
R = 8.314 J/(mol-K)
For the given problem,
ρ = 0.09 g/L = 0.09 kg/m³
T = 26°C = 26+273 K = 299 K
M = 1.008 g/mol = 1.008 x 10⁻³ kg/mol
Therefore
Note that 1 atm = 101325 Pa
Therefore
p = 2.2195 x 10⁵ Pa
= 221.95 kPa
= (2.295 x 10⁵)/101325 atm
= 2.19 atm
Answer:
2.2195 x 10⁵ Pa (or 221.95 kPa or 2.19 atm)

Point "C" is correct and all the remaining are false.
Note, HomeAtomic and HeteroAtomic compounds are the types of compounds, but not homogenous and heterogenous.
