Answer:
d. Radio wave
Explanation:
There are three types of mechanical waves, transverse waves, longitudinal waves, and surface waves
Answer:
Explanation:
<u>1) Data:</u>
a) n = ?
b) V = 50.0 dm³ = 50.0 liter
c) p = 100.0 kPa
d) T = 50 °C
<u>2) Physical law:</u>
<u>3) Constants:</u>
- R = 0.08206 atm-liter / K-mol
<u>4) Unit conversions:</u>
- T = 50 + 273.15 K = 323.15 K
- P = 100.0 kPa × (1 amt /101,325 kPa) = 0.9869 atm
<u>5) Solution:</u>
- n = 0.9869 atm × 50.0 liter / (0.08206 atm-liter /K-mol × 323.15 K)
Answer:
There are 1.253*10²⁴ particles in 2.080 moles
Explanation:
Avogadro's number is called the number of particles that make up a substance (usually atoms or molecules) that can be found in the amount of one mole. In other words, Avogadro's number is the number of molecules that one mole of any substance contains. Its value is 6.023 * 10²³ particles per mole.
So, you can apply a rule of three as follows: if 1 mole has 6.023*10²³ particles, then 2.080 moles, how many particles does it have?
amount of particles= 1.253*10²⁴ particles
<u><em>There are 1.253*10²⁴ particles in 2.080 moles</em></u>
POH = - log [ OH-]
pOH = - log [ 1 x 10⁻¹²]
pOH = 12
Magnesium is more metallic than chlorine because elements with metallic character readily lose electrons. Magnesium has an ionic charge of +2, ie. it will lose 2 electrons if possible. Chlorine has an ionic charge of -1, means that it will gain 1 electron if possible.
