Chemistry
1 answer:
DochEvi [55]3 years ago
6 0

Answer:

The answer to your question is: letter E,  1.77 L of 1.55 M Ba(NO3)2

Explanation:

Formula

Molarity = \frac{moles}{volume (L)}

moles = Molarity x volume (L)

a. 2.58 L of 0.0250 M Ba(NO3)2

moles = (0.025) (2.58)

moles = 0.065 M

b. 19.23 mL of 8.5 × 10−2 M Ba(NO3)2

moles = (8.5 x 10 ⁻²) (0.01923)

moles = 0.0016

c. No right answer.

d. 26.20 mL of 2.21 M Ba(NO3)2

 moles = (2.21)(0.0262)

moles = 0.058

e. 1.77 L of 1.55 M Ba(NO3)2

  moles = (1.55)(1.77)

  moles = 2.74            This solution needs the greatest concentration of

                                    Ba(NO₃)₂

The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.  

Usually radioactive elements have an unstable atomic nucleus.  

General formulas used in decay:  

\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{t/t\frac{1}{2} }}}

T = duration of decay  

t 1/2 = half-life  

N₀ = the number of initial radioactive atoms  

Nt = the number of radioactive atoms left after decaying during T time  

Nt=25 g

No=100 g

t1/2=5770 years

\tt 25=100\dfrac{1}{2}^{T/5770}\\\\\dfrac{1}{4}=\dfrac{1}{2}^{T/5770}\\\\2=T/5770\rightarrowT=11540~years

Ammonia chemically reacts with oxygen gas to produce nitric oxide and water . What mass of water is produced by the reaction of
Kay [80]

Full Question:

Ammonia chemically reacts with oxygen gas to produce nitric oxide and water. What mass of water is produced by the reaction of 7.7g of ammonia?

Be sure your answer has the correct number of significant digits.

Answer:

12.23g ≈ 12g (2 s.f)

Explanation:

Ammonia chemically reacts with oxygen gas to produce nitric oxide and water. The balanced chemical reaction is given as:

4 NH3 + 5 O2 ------->  4 NO + 6 H2O

From the reaction;

4 mole of ammonia reacts to produce 6 moles of water

From the question;

Moles = mass / molar mass

From the question;

moles of ammonia = mass / molar mass = 7.7 / 17 = 0.4529moles

Number of moles of water produced;

4 = 6

0.4529 = x

x = (0.4529 * 6 )  / 4

x = 0.67935moles

Mass of water =  moles * molar mass = 0.67935 * 18 = 12.23g ≈ 12g (2 s.f)
