Answer:

<h3>The answer is 1.63 %</h3>

Explanation:

The percentage error of a certain measurement can be found by using the formula

P(\%) =  \frac{error}{actual \:  \: number}  \times 100\% \\

From the question

actual mass = 9.80 g

error = 9.80 - 9.64 = 0.16

We have

p(\%) =  \frac{0.16}{9.80}  \times 100 \\  = 1.632653061...

We have the final answer as

<h3>1.63 %</h3>

Hope this helps you

Which of the following statements is TRUE? Which of the following statements is TRUE? Two electrons in the same orbital can have
Monica [59]

An orbital that penetrates into the region occupied by core electrons is less shielded from nuclear charge than an orbital that does not penetrate and therefore has a lower energy.

Explanation:

The only true statement from the given options is that "an orbital that penetrates into the region occupied by core electrons is less shielded from nuclear charge than an orbital that does not penetrate and therefore has a lower energy." Inner orbitals which are also known to contain core electrons feels the bulk of the nuclear pull on them compared to the outermost orbitals containing the valence electrons.

  • The nuclear pull is the effect of the nucleus pulling and attracting the electrons in orbitals.
  • This pull is stronger for inner orbitals and weak on the outer ones.
  • The outer orbitals are said to be well shielded from the pull of the nuclear charge.
  • Also, based on the quantum theory, electrons in the outer orbitals have higher energies because they occupy orbitals at having higher energy value.

Calorimetric studies show that the reaction is exothermic. 2NO2(g) N2O4(g) + 14.1 kcal. Based on this information, which one--if
FinnZ [79.3K]
In order for you to get the answer, please have in mind the following situation: To increase the molar concentration of N2O4(g), 2NO2(g) should also increase for equilibrium to occur. Now, this equation is exothermic. By <span>Le Chatelier's principle, equilibrium constant and reaction constants also come into play in terms of increasing or decreasing the temperature. After that I know you can find the answer. </span>

What would the wave speed be of a wave with a frequency of 64Hz and a wavelength of 102m
masya89 [10]

Answer: The speed of a wave with a frequency of 64 Hz and a wavelength of 102m is 6528 m/s.

Explanation:

The formula of a speed of a wave is frequency x the wavelength.

Therefore multiply 64 and 102.

You get 6528 m/s which is the correct answer.
