Answer:
First you need to know that the warm air is less dense than the colder air and thus it tends to rise; so snow-caves are constructed in some way that the tunnel entrance is below the main space, and so the warm air can be retained into the cave. In a typical snow-cave, you can reach temperatures over 0°C even when the temperature outside are under zero degrees celsius.
Answer:
5 .04 percent.
Explanation:
it is also known as sulfur dioxide. so it's 5.0.4 percent.
The element's Atomic number , which has 5 protons, 6 neutrons, and 2 electrons (the atomic number is the number of protons) = 5
<h3>What in an atomic number?</h3>
the number assigned to a chemical element according to its atomic number in the periodic system, which places the elements in ascending order of the number of protons in their nuclei. As a result, the atomic number is also the number of protons, which in a neutral atom is always equal to the amount of electrons.
<h3>Briefing:</h3>
Protons and neutrons are added to determine an element's mass number. The only number that may change while maintaining the identity of an element is the number of neutrons for that element (because the atomic number is the number of protons).
Mass number = protons + neutrons
<h3>According to the given data;</h3>
Given:
5 protons,
6 neutrons
2 electrons
Atomic number = ?
We know that the Mass number = protons + neutrons:
Mass number = protons + neutrons
Mass number = 5 + 6:
Mass number = 11
The element's Atomic number , which has 5 protons, 6 neutrons, and 2 electrons (the atomic number is the number of protons) = 5.

Answer:
We use coolant instead of water because when heated, water can start to accumulate the minerals that it has, and this can corrode the metal on your car. Other solution could be to use distilled water, but is will also corrode the metal of your radiator. One advantage of ethylene glycol is that prevents the corrosion in your radiator providing a protective coating to the metals.
