Which of the following measurements is equal to 2.3 dL?

Verdich [7]

2.3 dL = .23 liters. d=deci=10^-1 so you move the decimal place back once.

It's D because micro is 10^-6 (move the decimal place back 6 times) 230,000x10^-6=.23 liters or 2.3 dL.

Consider the reaction 4PH3(g) → P4(g) + 6H2(g) At a particular point during the reaction, molecular hydrogen is being formed at

Svetllana [295]

Answer:

The rate at which $P_4$ is being produced is 0.0228 M/s.

The rate at which $PH_3$ is being consumed is 0.0912 M/s.

Explanation:

$4PH_3\rightarrow P_4(g)+6H_2(g)$

Rate of the reaction : R

$R=\frac{-1}{4}\frac{d[PH_3]}{dt}=\frac{1}{6}\frac{d[H_2]}{dt}=\frac{1}{1}\frac{d[P_4]}{dt}$

The rate at which hydrogen is being formed = $\frac{d[H_2]}{dt}=0.137 M/s$

$R=\frac{1}{6}\frac{d[H_2]}{dt}$

$R=\frac{1}{6}\times 0.137 M/s=0.0228 M/s$

The rate at which $P_4$ is being produced:

$R=\frac{1}{1}\frac{d[P_4]}{dt}$

$0.0228 M/s=\frac{1}{1}\frac{d[P_4]}{dt}$

The rate at which $PH_3$ is being consumed :

$R=\frac{-1}{4}\frac{d[PH_3]}{dt}$

$0.0228 M/s\times 4=\frac{-1}{1}\frac{d[PH_3]}{dt}$

$\frac{-1}{1}\frac{d[PH_3]}{dt}=0.912 M/s$

At STP, when 3.75 liters of oxygen reacts with excess glucose, what volume of carbon dioxide does it produce?

yKpoI14uk [10]

Well, STP means standard temperature and pressure

In this condition, it is safe to assume that the moles of specie given will be equal to the moles of specie sought

I think the volume of the Carbon dioxide that it produced will also be 3.75 liters

Hope this helps

For each of the following, predict the complete, balanced chemical equation for the reaction that occurs when they are mixed. Ma

madam [21]

Answer:

1. The balanced chemical reaction is:

$HNO_3(aq)+NaOH(aq)\rightarrow NaNO_3(aq)+H_2O(l)$

2. The balanced chemical reaction is:

$2HI(aq)+Sr(OH)_2(aq)\rightarrow SrI_2(aq)+2H_2O(l)$

Explanation:

Hello there!

In this case, according to the given chemical reactions, it is necessary to keep in mind the cations and anions are switched around as a result of the bonds rearrangement in these neutralization reactions; therefore, we can proceed as follows:

1. The balanced chemical reaction is:

$HNO_3(aq)+NaOH(aq)\rightarrow NaNO_3(aq)+H_2O(l)$

Because all atoms are in the same amount at each side of the equation and the resulting salt is soluble.

2. The balanced chemical reaction is:

$2HI(aq)+Sr(OH)_2(aq)\rightarrow SrI_2(aq)+2H_2O(l)$

Because all atoms are in the same amount at each side of the equation and the resulting salt is soluble.

Best regards!
