Answer:

Mass = 4.326 kg

Explanation:

The relation between mass, volume and density is:

$density=\frac{mass}{volume}$

Given:

Density = 1.40g/mL

Volume = 3.090 L = 3.090 X 1000 mL =3090 mL

Mass = Density X volume = 1.40 X 3090 = 4326 grams

Mass = 4.326 kg

The standard free energy change for a reaction in an electrolytic cell is always:_________

sattari [20]

Answer: The standard free energy change for a reaction in an electrolytic cell is always positive.

Explanation:

Electrolytic cells use electric currents to drive a non-spontaneous reaction forward.

Relation of standard free energy change and emf of cell

$\Delta G^o=-nFE^0_{cell}$

where,

$\Delta G^o$ = standard free energy change

n= no of electrons gained or lost

F= faraday's constant

$E^0_{cell}$ = standard emf

$E^0_{cell}$ = standard emf = -ve , for non spontaneous reaction

Thus $\Delta G^o=(-ve)(-ve)=+ve$

Thus standard free energy change for a reaction in an electrolytic cell is always positive.

An initial mixture of nitrogen gas and hydrogen gas is reacted in a rigid container at a certain temperature by the reaction At

anygoal [31]

Answer: [N2]₀ = 10M and [H2]₀ = 11M

Explanation: To calculate the initial concentration, you would have to set up an ICE table, which is an organized way of tracking known quantities or the ones you want to find. ICE stands for:

I is initial amount;

C is change in concentration;

E is for equilibrium concentration;

For the mixture,

N2 3H2 2NH3

I [N2]₀ [H2]₀ 0

C - x -3x +2x

E [N2]₀ - x =8 [H2]₀ - 3x =5 2x =4

With the product, we can find "x":

2x=4

x=2M

With x=2, find the concentrations:

[N2]₀ - x = 8

[N2]₀ = 10M

[H2]₀ - 3x = 5

[H2]₀ = 11M

The initial concentrations of nitrogen gas [N2] is 10.0 M and of hydrogen gas [H2] is 11.0 M.

1. The speed limit on most city streets is (25 miles). How many meters per minute

irina1246 [14]

Answer:

$Speed = 670.56 \frac{m}{min}$

Explanation:

Given

$Speed = \frac{25 mi}{hr}$

Required

Convert to meters per minutes

$Speed = \frac{25 mi}{hr}$

Start by converting the speed from miles to meters

$1\ mile = 1609.34\ meters.$

So, we have:

$Speed = \frac{25 * 1609.34\ m}{hr}$

$Speed = \frac{40233.5\ m}{hr}$

Next, we convert time from hours to minutes

$1\ hour = 60\ minutes$

So, we have:

$Speed = \frac{40233.5\ m}{60\ min}$

$Speed = 670.56 \frac{m}{min}$

<em>Hence, the equivalent of 25 miles per hour is 670.56 meters per minutes</em>
