Answer:
C Condensation of water vapor
Explanation:
One of the components of the atmosphere is water vapour. Water vapour is always present in air.
This water vapour may combine with particles of dust and smoke and condense around them to form clouds.
As more water vapour condenses and coalesces, the clouds become thicker and precipitation eventually follows.
<h2>Isotopes of uranium</h2>
Uranium is a naturally occurring radioactive element that has no stable isotope. It has two primordial isotopes, uranium-238 and uranium-235, that have long half-lives and are found in appreciable quantity in the Earth's crust. The decay product uranium-234 is also found.
<h3 /><h3>SF: Spontaneous fission</h3>
Answer:
Explanation:
Hello.
In this case, given the chemical reaction, we can compute the grams of oxygen by using the 98.2 g of water via the 2:1 mole ratio between them, the molar mass of water that is 18.02 g/mol, the molar mass of gaseous oxygen that is 32.00 g/mol and the following stoichiometric procedure relating the given information:
In which the result is displayed with three significant figures because the given mass of water 98.2 g, has three significant figures too.
Best regards!
2Mg+O₂⇒2MgO
It can be a combustion reaction, or it can be a combination reaction
