<h2>Answer:</h2>
At 189 K volume = 32.0 cm
As volume of gas is directly proportional to temperature.
As the temperature increase the volume of gas will also increase.
so
Volume at 1 K = 32/189
Volume at 242 K = 32/189 * 242 = 40.97 cm.
Gas occupy 40.97 cm volume at 242 K.
Answer:
≈29.94 [°C].

Answer:
Explanation:
Hello there!
In this case, since we need to dilute the 1.75-M HCl, and the total number of moles remain unchanged, we can write:
And in terms of volume and concentration:
Thus, we can solve for the volume of the concentrated HCl as shown below:
Therefore, we plug in the data to get:
Best regards!
Answer:
The ratio of the mass of an adult rhino to the mass of a small egret is
(1400 kg)/(0.76 kg) = 1842.11
The ratio of the mass of a proton to the mass of an electron is
1836.15
The two ratios are very similar, the ratio of the masses of the proton to the electron being slightly smaller.
Answer: Glaciers can erode around rock. They shift over time so it causes the rock (or glacier) to erode. If it erodes enough it creates a valley. The glacier causes it to go deeper and deeper! That is how valleys are made!
