What volume does 8.5 g NH₃ occupy at STP?

Chemistry
1 answer:
vesna_86 [32]2 years ago
5 0
First, convert grams to moles by dividing 8.5 by the molar mass of NH₃ (N=14,H=1)
14+1+1+1=17
8.5/17=.5 moles NH₃
Multiply .5 by the conversion factor of moles to L (22.4)
.5*22.4=11.2 L NH₃
11.2 is just 11.21 rounded down, so your answer is C) 11.21 L

How many formula units are there in 212 grams of mgCl2
AleksandrR [38]

Formula units are there in 212 grams of MgCl₂ are 830.56

Formula is the empirical of any ionic or covalent network solid compound used as an independent entity for stoichiometric calculations and it is the lowest whole number ratio of ions represented in an ionic compound

Here given data is

MgCl₂ = 212 grams

1 mole of magnesium chloride has mass = 95.211 gram and contains 6.022×10²³formula units of magnesium chloride

Here 212 grams×6.022×10²³form unit of MgCl₂/95.211 gram = 830.56

Answer:

1) 70

2) conduction

3) The ground absorbs the solar radiation and

releases it throughout the later afternoon.

4) transpiration

5) convection

6) cumulonimbus

7) reflectivity of Earth’s surface

8) As temperature increases, air pressure

increases.

9) thermosphere

10) convection cells, pressure belts, and the

Coriolis effect

11) radiation

12) pollen

13) scattering

14) thermosphere

15) The different types of clouds are:

<u>cumulus:</u><em><u> </u></em><em>Cumulus clouds are clouds which have flat bases and are often described as "puffy", "cotton-like" or "fluffy" in appearance. Their name derives from the Latin cumulo-, meaning heap or pile. </em>

<u>cirrus</u><em>:</em><em> </em><em>Cirrus is a genus of atmospheric cloud generally characterized by thin, wispy strands, that typically appear white or light grey. The name is derived from the Latin word cirrus, meaning 'ringlet' or 'curling lock of hair'. Such a cloud can form at any altitude between 5,000 and 13,700 m above sea level.</em>

<u>stratus:</u><em> </em><em>Stratus clouds are low-level clouds characterized by horizontal layering with a uniform base, as opposed to convective or cumuliform clouds that are formed by rising thermals.</em>

<u>nimbus</u>: <em>Nimbostratus clouds are dark, grey, featureless layers of cloud, thick enough to block out the Sun and produce persistent rain. Height of base: 2,000 - 10,000 ft. Shape: Bands or areas of individual cells. Latin: nimbus - rainy cloud; stratus - flattened or spread out. Precipitation: Continuous rain or snow likely.</em>

16) the tradewinds

17) the location’s latitude

18) Cirrus clouds

19) the ozone layer

20) Global winds are created by both the spin of

the Earth (Coriolis effect) and the differences

in temperature between the equator and

the polar areas. These winds are often

grouped together as trade winds, easterlies,

and westerlies.

21) nitrogen

22) the Miller-Urey hypothesis

the Oparin-Haldane hypothesis

23) ammonia gas

24) cumulus

25) It determines the mass of water in a volume of air

Answer:

See explanation

Explanation:

A net ionic equation shows only the chemical species that are involved in a reaction, while a complete ionic equation also includes the spectator ions(Khan Academy).

From the species shown in the image we can write the molecular equation, ionic equation and net ionic equation and also identify the spectator ions.

Chemical equation: KX + BY --------> BX + AY

Ionic Equation; X^- + A^+ + B^+ + Y^- -----> BX + A^+ + Y^-

Spectator ions;  A^+ and Y^-

Net Ionic Equation; X^- + B^+ ------> BX
