A hypothesis is a stage in scientific investigation that follows shortly after asking a simple scientific question.
Hypothesis is simply a scientific guess that is logical in nature.
It presents a problem in a manner in which the problem is stated, the cause and the likely outcome can be predicted.
After a hypothesis formulation, the experiment is conducted and results of findings weighed against the predictions of the statement.

Write the empirical formula

stira [4]

Answer:

$1) NH_{4}IO_{3}\\2) Pb(IO_{3})_{4} \\3) NH_{4}(C_{2}H_{3}O_{2})\\4) Pb(C_{2}H_{3}O_{2})_{4}$

Explanation:

$1) NH_{4}^{+}IO_{3}^{-} ---> NH_{4}IO_{3}\\2) Pb^{4+}(IO_{3}^{-})_{4} --->Pb(IO_{3})_{4} \\3) NH_{4}^{+}(C_{2}H_{3}O_{2})^{-} ---> NH_{4}(C_{2}H_{3}O_{2})\\4) Pb^{4+}(C_{2}H_{3}O_{2})^{-} _{4} --->Pb(C_{2}H_{3}O_{2})_{4}$

Express the frequency in inverse seconds. n=5-->n=1

Natalija [7]

The frequencies expressed in inverse seconds are 5 s⁻¹ and 1 s⁻¹.

<h3>What is frequency?</h3>

Frequency is the number of complete cycles in a second made by a wave.

F = 1/T

F = n/t

F = 5/s = 5 s⁻¹ = 5Hz

F = 1/s = 1 s⁻¹ = 1Hz

If 100.0 grams of na3n decompose to form sodium and nitrogen, how many moles of sodium are formed? write and balance equation be

Yakvenalex [24]

The balanced equation is:
$2Na_3N-\ \textgreater \ 6Na + N_2$

Then proceed with the following equations.

$100g Na_3N*(\frac{1molNa_3N}{82.98gNa_3N})*(\frac {6mol Na}{2molNa_3N})*(\frac {22.99gNa}{1molNa})=83.12gNa$

The answer is $83.12gNa$ .
