A pressure of 745 mm hg equals select one:
Flura [38]
As we know that,

                                        1 mm Hg  =  1 torr
So,
                                    745 mm Hg  =  X

                         X  =  (745 mm Hg × 1 torr) ÷ 1 mm Hg

                         X  =  745 torr

Also,
                                    1 mm Hg  =  133.325 Pa
So,
                                    745 mm Hg  =  X

                         X  =  (745 mm Hg × 133.325 Pa) ÷ 1 mm Hg

                         X  =  99327 Pa

Result:
          Option-A (745 torr) is the correct answer.

How many grams of NaF form when .508 mol of HF react with excess Na2SiO3?
jonny [76]
2HF + Na2SiO3 ---->  2NaF +  H2SiO3   is the balanced equation.

2 moles of HF  form 2 moles of NaF

therefore 0.508 Mol  HF forms 0.508 mol of NaF

In grams this is 0.508( rel atomic mass of Na + RAM of F)
                        = 0.508 (22.99+19)
                        =  21.33 grams

Need help with balancing equations
solniwko [45]

The balanced equation of the reaction shows that the mole of atoms on both sides of the reaction are equal.

<h3>What are balanced chemical equations?</h3>

Balanced chemical equations are equations in wgich the moles of each species on both sides of the reaction are equal.

To balance chemical equations, numerical coefficients are placed in front of the species in the reaction.

The balanced equations of the reaction are as follows:

3Pd + 4H_3PO_4 \rightarrow Pd_3(PO_4)_4 + 6H_2 \\

C_{11}H_{24} + 17O_2 \rightarrow 11CO_2 + 12H_2O \\

2Al(HCO_3)_3 + 3H_2SO_4\rightarrow Al_2(SO_4)_3 +6CO_2 +6H_2O \\

Therefore, the balanced equation of the reaction shows that the mole of atoms on both sides of the reaction are equal.

Need help with this please
Ivanshal [37]

Answer:

-3.06 is the overall voltage produced

Explanation:

Potassium and Tin are connected in an electrochemical series.

In a series circuit, the resultant voltage is equal to the sum of voltage drops at all points in the circuit.

Here,

The voltage drop at potassium = -2.92

The voltage drop at Tin = -0.14

The net voltage

= -2.92 -0.14 \\= -3.06
