SnO2 + 2H2 → Sn + 2H2O

Chemistry
1 answer:
anzhelika [568]3 years ago
7 0

Answer:- B: 4.21 is the correct option.

Solution:- The given balanced equation is:

SnO_2+2H_2\rightarrow Sn+2H_2O

From the balanced equation, there is 1:1 mol ratio between SnO_2 and Sn.

To calculate the moles of SnO_2 required to produce500.0 grams of Sn, we need to convert the grams to moles and multiply it by the mole ratio as:

500.0gSn(\frac{1moleSn}{118.71gSn})(\frac{1moleSnO_2}{1moleSn})

= 4.21moleSnO_2

So, the correct option is B: 4.21 moles.

an aqueous solution contains 1.2mM of total ions. if the solution is NaCl (aq), what is the concentration of chloride ions?
Genrish500 [490]

Explanation:

As the total concentration is given as 1.2 mM. And, it is also given that salt present in the solution is NaCl.

As sodium chloride is an ionic compound so, when it is added to water then it will dissociate into sodium and chlorine ions as follows.

           NaCl \rightarrow Na^{+} + Cl^{-}

So, it means in total there will be formation of 2 ions when one molecules of NaCl dissociates.

Therefore, concentration of chlorine ions will be calculated as follows.

       Concentration of Cl^{-} ions = \frac{1.2mM}{2}

                                                        = 0.6 mM

Thus, we can conclude that the concentration of chloride ions is 0.6 mM.

I NEED HELP ASAP!!!
Rus_ich [418]

Explanation:

To answer this question, we'll need to use the Ideal Gas Law:

p

V

=

n

R

T

,

where

p

is pressure,

V

is volume,

n

is the number of moles

R

is the gas constant, and

T

is temperature in Kelvin.

The question already gives us the values for

p

and

T

, because helium is at STP. This means that temperature is

273.15 K

and pressure is

1 atm

.

We also already know the gas constant. In our case, we'll use the value of

0.08206 L atm/K mol

since these units fit the units of our given values the best.

We can find the value for

n

by dividing the mass of helium gas by its molar mass:

n

=

number of moles

=

mass of sample

molar mass

=

6.00 g

4.00 g/mol

=

1.50 mol

Now, we can just plug all of these values in and solve for

V

:

p

V

=

n

R

T

V

=

n

R

T

p

=

1.50 mol

×

0.08206 L atm/K mol

×

273.15 K

1 atm

= 33.6 L

this is not the answer but it will help you

do by the formula it is on the answer
