Answer:
Only the number of neutrons change.
Answer:
The new pressure of the gas comes out to be 400 KPa.
Explanation:
Initial volume of gas = V =
Initial pressure of gas = P = 120 KPa
Final volume of gas = V' =
Assuming temperature to be kept constant.
Assuming final pressure of the gas to be P' KPa

New pressure of gas = 400 KPa
<span>To solve this problem, You need to look up a picture/diagram of the electromagnetic spectrum. This will have the wave regions listed as well</span> as frequencies and wavelength.
Wavelength is distance/length of one wave, which can be calculated using frequency (hz = s^-1) and the speed of light.
2.998 x 10^8 m/s ÷ 3 x 10^19 s^-1 = 9.99 x 10^-12 m
The Frequency given falls in between X-rays and Gamma rays. The wavelength however; is in the Gama ray region.
Answer:
D. Catalyst
Explanation:
Because a Catalyst is a substance that causes or accelerates a chemical reaction without itself being affected.
Answer:
there are three significant digits.
Explanation:
Thus, 21.8, 0.283 and 567 all have three significant digits. 2. Zeros appearing between non-zero digits are significant. Thus, 505 and 0.206 have three significant digits, while 50,005 has five significant digits. (from google)
