How many grams of Br are in 255 g of CaBr2?

1 answer:

8 0

Molar mass:

Br = 79.904 g/mol
CaBr2 = 199.886 g/mol

<span>CaBr2 = 2 Br + Ca
</span>
199.886 g --------------- 2 x 79.904 g
255 g -------------------- ?? ( mass of Br )

255 x 2 x 79.904 / 199.886 =

40751.04 / 199.886 =>203.87 g of Br

hope his helps!

A steam engine (assume a Carnot engine ) has an efficiency of 50.8%. If the waste heat has a temperature of 72.4 ◦C, what is the

Inessa05 [86]

Answer:

The temperature of the boiler is approximately 147.1 °C

Explanation:

A Carnot engine is an ideal engine that has the highest efficiency among all the engines because the second law of thermodynamics.That efficiency $\eta$ is:

$\eta=1-\frac{T_{c}}{T_{h}}$

with $T_{h}$ the temperature of the hot reservoir (the boiler temperature) and $T_{c}$ the temperature of the cold reservoir (the steam temperature). Solving for $T_{h}$ :
