Hm I’m confused, if you mean what are they weighting, it’s they :)
I assume you’re looking for a balanced equation.
SiCl4 + 2H2O = SiO2 + 4HCl
Answer:
55.845 u
Explanation:
Fe, iron, has 29 neutrons and a atomic mass of 55.845 u
Answer:
Heat transfer = Q = 62341.6 J
Explanation:
Given data:
Heat transfer = ?
Mass of water = 50.0 g
Initial temperature = 30.0°C
Final temperature = 55.0°C
Specific heat capacity of water = 4.184 J/g.K
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 55.0°C - 30.0°C
ΔT = 25°C (25+273= 298 K)
Q = 50.0 g × 4.184 J/g.K ×298 K
Q = 62341.6 J
