A device for measuring atmospheric pressure is a _____.

Chemistry
1 answer:
Damm [24]4 years ago
4 0

Answer: Barometer

<span>The device used in meteorology to measure atmospheric pressure is called a barometer. It consists of a long glass tube filled with mercury and turned upside down into a container of mercury. The tube is closed at one end and open at the other which works by balancing the mercury in the glass tube against the outside air pressure. As air pressure increases, the air becomes heavier and it pushes more of the mercury up into the tube. As air pressure decreases, mercury drains from the tube. </span>

Tema [17]

Answer:

45.13 psi

Explanation:

Assuming the volume does not change

P1/T1 = P2/T2         T  must be in Kelvin

40/(273.15) = P2/(273.15 + 35)       P2 = 45.13 psi

Explain and illustrate the notation for distinguishing between the different p orbitals in a sublevel.
masha68 [24]

Here, the three different notation of the p-orbital in different sub-level have to generate

The value of azimuthal quantum number (l) for -p orbital is 1. We know that the magnetic quantum number m_{l} depends upon the value of l, which are -l to +l.

Thus for p-orbital the possible magnetic quantum numbers are- -1, 0, +1. So there will be three orbitals for p orbitals, which are designated as p_{x}, p_{y} and p_{z} in space.

The three p-orbital can be distinguish by the quantum numbers as-

For 2p orbitals (principal quantum number is 2)

1) n = 2, l = 1, m = -1

2) n = 2, l = 1, m = 0

3) n = 2, l = 1, m = +1

Thus the notation of different p-orbitals in the sub level are determined.

Nata [24]

Answer:

1. How do metals and non-metals react with acids?

Ans : Non metals does not react with acids while metals react with acids and produce hydrogen gas that burns with a 'pop'sound.

2. Write and explain the chemical equation for the reaction of magnesium with sulphuric acid and aluminium with hydrochloric acid.

Magnesium + sulphuric acid = Hydrogen + salt

Mg(s) + H2SO4 (aq) MgSO 4(aq) +H2 (g)

Aluminium + Hydrochloric acid = Hydrogen + Aluminium chloride

2Al(s)+6HCl(aq)→2AlCl3(aq)+3H2(g)

Does a precipitate form when a solution of sodium acetate and a solution of ammonium sulfate are mixed together?
e-lub [12.9K]
<h3><u>Answer</u>;</h3>

No, a precipitate does not form

<h3><u>Explanation</u>;</h3>
  • Precipitation involves mixing or combining solutions that contain soluble ionic compounds to form an insoluble ionic compound by a reaction.
  • Sodium acetate and ammonium sulfate are both soluble ionic compounds, which implies that they exist as ions in aqueous solution.
  • <em><u>When they combine they form NH4CH3COOH and sodium sulfate, Na2SO4, which are both soluble salts, as all salts of ammonium and sodium are soluble.</u></em>
  • <em><u>Both ammonium acetate and sodium sulfate are soluble because there are no anions that can form an insoluble solid with NH4+ and Na+ cations. </u></em>
