Chemistry

Nataly [62]3 years ago
8 0

Explanation:

Normal Earth temperature means the standard temperature and pressure conditions. At STP, temperature is 273 K or zero degree celsius and pressure is 1 atm.

For gases at STP, volume is equal to 22.4 liter.

So, at normal Earth temperature sodium exists as a solid whereas oxygen exists as a gas.

On the other hand, both bromine and mercury exists as liquid at normal Earth temperature.

1) What is air pressure? (4 Points)
Nataly [62]

<span>1)    </span><span>What is air pressure? (Answ</span>er: Atmospheric pressure, sometimes also called barometric pressure, is the pressure within the atmosphere of Earth.)

<span>2)    </span><span>What is a barometer and what is it used to measure? <span>(Answer: A barometer is a scientific instrument used in meteorology to measure atmospheric pressure. Pressure tendency can forecast short term changes in the weather.)</span></span>

<span>3)    </span><span>How does air pressure change?  <span>(Answer: Millibar values used in meteorology range from about 100 to 1050. At sea level, standard air pressure in millibars is 1013.2. Weather maps showing the pressure at the surface are drawn using millibars. ... This change in pressure is caused by changes in air density, and air density is related to temperature.)</span></span>

<span>4)    </span><span>Why is cooler, drier air related to High Pressure? <span>(Answer: This is due to density differences between the two air masses. Since stronger high-pressure systems contain cooler or drier air, the air mass is denser and flows towards areas that are warm or moist, which are in the vicinity of low pressure areas in advance of their associated cold fronts.)</span></span>

<span>5)    </span><span>Why is warm, moister air related to Low Pressure?  <span>(Answer: When air warms, its molecules scatter. The air becomes lighter and rises.)</span></span>

The molecular formula for butane is C4H10. Determine the percent composition for
masya89 [10]

%Mass

Ar C = 12 g/mol, Mr C₄H₁₀ = 58 g/mol, Ar H = 1 g/mol

\tt C=\dfrac{4.12}{58}\times 100\%=82.8\%\\\\H=100\%-82.8\%=17.2\%

or

\tt H=\dfrac{10.1}{58}\times 100\%= 17.2\%

A reaction between ammonia gas and chlorine gas produces
7nadin3 [17]

Answer:

32.25

Explanation:

8NH3 + 3Cl2 → 6NH4Cl + N2

NH3 = 17 g/mol

number of moles = 1

NH4Cl= 43 g/mol

number of moles = 3/4

mass= 43 × ¾ ≈ 32.25 g

Cuando aumenta la temperatura dentro de un recipiente cerrado que contiene un gas este se expande/comprime por que las partícula
Evgesh-ka [11]

Answer:

expande

forman se alejan

Explanation:

Según las leyes de los gases ideales;

La ley de Charles establece que el volumen de una masa dada de gas ideal es directamente proporcional a su temperatura a la presión simultánea.

Esto significa que cuando se calienta una masa dada de gas ideal, el gas se expande y las moléculas de gas se alejan unas de otras de acuerdo con la ley de Charles.
