The charge that flows through the shower in 300 seconds is 18000C. The electric shower has a power of 13.8 kW. Calculate the resistance of the heating element in the shower.

Firstly, we want to define what information we know from the question: ∆Q = 18000C; ∆t = 300s, P = 13.8kW Therefore, to calculate the resistance we can use the power equation, P=I 2 R, and calculate the curr...

In Stage 2 of a reaction, 40 kg of titanium chloride was added to 20 kg of sodium. The equation for the reaction is: TiCl4 + 4Na -> Ti +4NaCl Relative atomic masses (Ar): Na = 23 Cl = 35.5 Ti = 48 Explain why titanium chloride is the limiting reactant.

To calculate which of titanium chloride or sodium is limiting, convert both into mol so they are directly comparable. You cannot compare in masses because in equations there is a conservation of moles and no...
