Given , Speed of light = 3 × 10⁸ m/s
Distance = 40 × 1.61× 1000 m
= 264400 m
We know that, speed = distance/time
so, time = distance/speed
t = 264400 / 3 × 10⁸
t = 0.00881333 sec Approx
The answer is 0.00881333 sec Approx
A balanced equation representing the acid-base reaction that allows the calculation of the moles of aspirin in a sample is
⇒ 
Aspirin, also known as acetylsalicylic acid, is a nonsteroidal anti-inflammatory drug used to reduce pain, fever, and/or inflammation, and as an antithrombotic.
Aspirin is a benzoic acid with an ortho-substituted acylated alcohol function (actually a phenol). Therefore, two reactions can occur when aspirin and NaOH are combined: In fact, several aspirin formulations contain this ingredient.
Hence, A balanced equation representing the acid-base reaction that allows the calculation of the moles of aspirin in a sample is
⇒

Molar mass NaCl = 58.44 g/mol
number of moles:
mass NaCl / molar mass
145 / 58.44 => 2.4811 moles of NaCl
Volume = 3.45 L
Therefore :
M = moles / volume in liters:
M = 2.4811 / 3.45
M = 0.719 mol/L⁻¹
hope this helps!
Answer:
they are carried away and deposited wherever.
there are many wanys sediments can be carried so common examples would be... by wind, water, or by animals.
Explanation:
Answer:
When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
