How many atoms are in 22 grams of copper metal?
strojnjashka [21]
Atomic mass Cu = 63.546 a.m.u

63.546 g ---------------- 6.02x10²³ atoms
22 g --------------------- ??

22 x (6.02x10²³ ) / 63.546 => 2.08x10²³ atoms

2.2 liters at 20 degrees Celsius if the pressure doesn’t change what is the new temperature at 2.6 liters
Mamont248 [21]
Based on the question, it is evident that this question rests on the premise of Charle's Law, which essentially states that temperature is proportional to volume once pressure and mass remain constant.

Thus by Charle's Equation:   \frac{ V_{1} }{ T_{1} }  =  \frac{ V_{2} }{ T_{2} }

Since the initial volume = 2.2 L; the initial temperature = 20 C; and the final volume = 2.6 L,
                           then V₁ = 2.2 L; T₁ = 20 C; V₂ = 2.6 L and what we would be
                           finding is T₂ (the final/new temperature)

Now,   T_{2}  =  \frac{(V_{2})   (T_{1}) }{V_{1}} 

     ⇒   T_{2}  =  \frac{(2.6 L)   (20  ^{o} C) }{2.2 L}

     ⇒   T_{2} = 23.64   ^{o}C


        ∴  the new temperature is ≈  23.6 °C

What is the polarity of black pepper
leva [86]

Answer:

Polarity in chemistry referred to physical properties of compounds related to solubility, melting and boiling properties.

Polarity of black pepper can be seen when black pepper is sprinkled on water. The balck pepper float on water and get displaced if touched.

It means black pepper is non-polar and have no difference in electronegativity between bonded atoms. Black pepper is so light in weight and non-polar, the surface tension of water keep it floating in the water.
