Answer:
RH = 20%
Explanation:
Data given:
water pressure at 0°C = 4.85 g/m³
Actual water vapor density = 0.97 g/m³
Relative humidity (RH) = ?
Solution:
Formula used
Relative humidity (RH) =
x 100%
As we know that at 0°C water vapor have 4.85 g/m³ saturated vapor density.
So,
put values in the above formula
Relative humidity (RH) = 0.97 g/m³ / 4.85 g/m³ x 100%
Relative humidity (RH) = 0.2 x 100%
Relative humidity (RH) = 20%
So,
Relative humidity (RH) = 20%

Answer:
2Na(s) + 2HCl(aq) —> 2NaCl(aq) + H2(g)
Explanation:
Na(s) + HCl(aq) —> NaCl(aq) + H2(g)
Writing an ionic equation will actually help us to understand the equation and also to balance it. This is illustrated below:
Na + H+Cl-
Na is higher than H in the activity series and as such, it will displaces H from the solution and form NaCl with H2 liberated as shown below
Na + H+Cl- —> Na+Cl- + H2
Now, put 2 in front of Na, H+Cl- and Na+Cl- to balance the equation as shown below:
2Na + 2H+Cl- —> 2Na+Cl- + H2
Now we can write the elemental equation as follow:
2Na(s) + 2HCl(aq) —> 2NaCl(aq) + H2(g)

Answer:
pH = 4.4
Explanation:
pH = -log[H₃O⁺]
= -log(4.3 × 10⁻⁵)
pH = 4.37 = 4.4
I'm actually learning this in my chemistry class right now lol. Hope this helps though. :)
