If 1.27 moles of bromine gas (Br2) react with excess phosphorus (P), how many moles of phosphorus tribromide (PBr3) will be prod
frez [133]

Answer:

0.85 mole of PBr3.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

3Br2 + 2P —> 2PBr3

From the balanced equation above,

3 moles of Br2 reacted to produce 2 moles of PBr3.

Therefore, 1.27 moles of Br2 will react to produce = (1.27 x 2)/ 3 = 0.85 mole of PBr3.

Therefore, 0.85 mole of PBr3 is produced by the reaction.

The Prandtl number, Npr, is a dimensionless group important in heat transfer calculations. It defined as Cuk, where C, is the he
VARVARA [1.3K]

Answer:

The Prandlt number for this fluid is 1630.

Explanation:

The Prandlt number is defined as:

Pr=\frac{C_p\mu}{k}

To compute the Prandlt number for this case, is best if we use the same units in every term of the formula.

\mu=1936\frac{lb}{ft*h}*\frac{1000g}{2.205lb}*\frac{3.281ft}{1m}*\frac{1h}{3600s}  \\ \\\mu=800 \frac{g}{m*s}

Now that we have coherent units, we can calculate Pr

Pr=\frac{C_p\mu}{k}=\frac{0.583*800}{0.286}= 1630

how do the components that process information in the ENIAC compare with the components that process in a modern laptop computer
STALIN [3.7K]
For starters, ENIAC was as big as a room and had many parts that don't even exist nowadays. It was operated by humans and broke down often. Information processing was a tedious and a difficult process. Modern components enable much faster data travel, fewer opportunities for the thing to break down, and an easier access for people to process data.
