Answer:

Boron Selenate

Explanation:

The compound contains B^3+ and the selenate anion SeO4^2-.

Selenate (Se(VI)) is quite weakly adsorbed by oxides and clays almost at neutral pH. Hence, oxidation of Se(IV) to Se(VI) enhances selenium mobility and persistence in natural water bodies. High concentrations of selenate can occur in agricultural drainage waters in arid areas. Selenate is further found in irrigation waters across the USA.

Many selenate compounds are known having various counter ions.

If five moles of a gas at a pressure of 5.4 kpa have a volume of 120 liters, what is the temperature?

ra1l [238]

<h3>The temperature is 15.58 kelvin </h3>

<em><u>Solution:</u></em>

<em><u>Ideal gas equation is given as:</u></em>

$PV = nRt$

Where,

P = pressure

V = volume

n = amount of substance

R = ideal gas constant

T = temperature

From given,

V = 120 liters

n = 5 moles

$R = 8.314\ \frac{Lkpa}{mol\ K}$

P = 5.4 kPa

T = ?

Therefore,

$5.4 \times 120 = 5 \times 8.314 \times T\\\\648 = 41.57 \times T\\\\T = 15.58\ kelvin$

Thus the temperature is 15.58 kelvin

If 6.4 miles of Fe react with excess O2, how many miles of Fe2O3 can be formed? 4 Fe + 3 O2 -> 2 Fe2O3

Yuri [45]

I'm assuming that by "miles" you mean moles.

If O2 is the excess reactant, that means Fe is the limiting reactant. That means that the amount of product being formed depends on the amount of Fe reactant present. To calculate the moles of Fe2O3 formed, start with the given 6.4 moles of Fe and use the mole to mole ratio given by the reaction as shown below:

6.4 mol Fe x $\frac{2 mol Fe2O3}{4 mol Fe}$ = 3.2 mol Fe2O3

The reaction for producing glucose in plants, called photosynthesis, is:

Firlakuza [10]

Answer:

41.16 moles of H2O

Explanation:

Ratio for the products-reactants is 1:6, so 1 mol of glucose is produced when plants use 6 moles of water.

Then, let's make a rule of three:

1 mol of glucose is produce by using 6 moles of water

6.86 moles of glucose are produced by the use of (6 . 6.86)/1 = 41.16 moles of H2O
