Answer : Atmosphere.

Explanation : The combination of gases that surrounds and protects the earth is known as Atmosphere.

An atmosphere is defined as a layer or a set of multiple layers of gases surrounding a planet or other material body, which is held in place by the gravity of that body.

It acts as an envelope of air around the earth and protects the earth from the harmful ultraviolet rays coming from the sun. Air in the atmosphere contains high amount of nitrogen which is 78.09 percent, oxygen is 20.95 percent, argon is 0.9 percent argon, carbon dioxide is 0.04 percent there is also small amounts of other gases.

How many neon atoms are contained in (7.27x10^2) grams of neon?

statuscvo [17]

Answer: 2.19x10^25 atoms

Explanation:

Molar Mass of Neon = 20g/mol

1mole(20g) of Neon contains 6.02x10^23 atoms.

Therefore, 7.27x10^2g of Neon will contain x atoms i.e

X atoms = (7.27x10^2x6.02x10^23)/20 = 2.19x10^25 atoms

If a reaction occurs when a piece of metal is placed in a solution, what can you conclude about the solution?

USPshnik [31]

Hello!

If a reaction occurs when a piece of metal is placed in a solution, you can conclude that the solution is <span>probably acidic because bases rarely react with metals.

Strong Acids, like HCl, react with metals to produce salts and release gaseous hydrogen (H</span>₂) which is evidenced by the generation of bubbles in the solution. The general chemical equation for this kind of reactions for a metal M and an acid HA is:

2M(s) + 2HA(aq) → 2MA(aq) + H₂(g)
