Answer:
Explanation:
Mg + 2HCl = Mg Cl₂ + H₂
.594 g = .594 / 24.3
= .02444 mole 
Heat evolved = msΔ T , m is mass of water ( solvant ) , s is specific heat of water , Δ T is rise in temperature 
= 100 x 4.2 x ( 41.83 - 25 )
= 7068.6 J 
.02444 mole  of Mg evolves 7068.6 J of heat 
1 mole of Mg evolves 7068.6 /.02444 J 
= 289222.6 J 
= 289 kJ . 
Molar heat enthalpy = 289 kJ . 
 
        
             
        
        
        
The answer will be A & B not only because it makes sense but evaporation is taking water away not adding to (gaining)
        
             
        
        
        
Answer:
The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength. ... The more rigid (or less compressible) the medium, the faster the speed of sound
