Answer:
C4H10
Explanation:
you already written it :)
E = energy in the light rays = h ν = h c /λ = 6.67 * 10×⁻³⁴ * 3 * 10⁸ / (5.84*10⁻⁸) J = 3.42 * 10⁻18 JKinetic energy of electrons = 1/2 m u^2 = 1/2 * 9.1 * 10⁻³¹ * (2.45 * 10⁶)² J = 2.73 * 10⁻¹⁸ J The ionization energy = (3.42 - 2.73) * 10⁻¹⁸ J = 6.9 * 10⁻¹⁹ J
What are the options the your question
Answer:
Option B
Explanation:
All people who are asked to testify in a criminal case must first be issued a subpoena by law enforcement, is a "false statement" or option B. A subpoena is a request to appear in court which is usually given out by the attorneys who are a part of the case, the law enforcement does not give out subpoenas, so this is indeed a false statement.
Hope this helps.

Answer:</h3>
79.8 ml
<h3>
Explanation:</h3>
Boyle's law describes the relationship between pressure and volume when the temperature is constant. For this question, I will be rounding to significant figures.
Boyle's Formula
When describing the relationship between pressure and volume, the formula
. In this formula,
is the initial pressure and volume. On the other side,
is final pressure and volume. So, to find a missing variable you must plug in the values you are given.
Final Volume
Remember when solving this question to remain constant in your units. When we plug in the values we know we are given:
Now, we can multiply the left side
Finally, we can divide by 385 to isolate the final volume
This gives the final volume of 79.8mL.
