Answer:
The moles of gas is 0.009474 moles.
Explanation:
Given that,
Volume = 526 mL
Pressure = 346 mmHg
Temperature = 35.0°C
We need to calculate the moles of gas
Using formula of ideal gas

Where, P = pressure
V = volume
R = gas constant
T = temperature
Put the value into the formula


Hence, The moles of gas is 0.009474 moles.
Answer: The transition metals make up the middle block of he periodic table
Answer: The mole ratio of sodium to sodium chloride 2:2.
Explanation:
As the given reaction equation is as follows.

Here, 2 moles of sodium reacts with 1 mole of
and leads to the formation of 2 moles of NaCl.
This means that 2 moles of sodium gives 2 moles of NaCl on reaction with chlorine.
Hence, the ratio of moles of sodium to sodium chloride is 2:2.
Thus, we can conclude that the mole ratio of sodium to sodium chloride 2:2.
Answer:
230hz
Explanation:
Hello,
To solve this question, we gave to use the relationship between velocity-frequency-wavelength to find the frequency in this question.
V = Fλ
V = velocity or speed of the wave
F = frequency of the wave
λ = wavelength of the wave
Data;
V = 414m/s
λ = 1.8m
f = ?
V = fλ
f = v/λ
f = 414/1.8
f = 230hz
The frequency of the wave is 230hz
