Answer:

You could rephrase this to make more sense? You could say “Mary me please!” This is a complete sentence. It has a verb and noun making it a full sentence. “Marry” is your verb and your noun is “me” I hope this helped have a good day! :) Please mark me the brainliest?

Suppose two 200.0-L tanks are to be filled separately with the gases helium and hydrogen. What mass of each gas is needed to pro

Aneli [31]

Answer:

Mass of helium = 4426.9524 g

Mass of hydrogen gas = 2213.4762 g

Explanation:

Pressure = 135 atm

Temperature = 24 °C

Volume = 200 L

Number of moles = ?

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15

So,

T₁ = (24 + 273.15) K = 297.15 K

Using ideal gas equation as:

PV=nRT

where,

P is the pressure

V is the volume

n is the number of moles

T is the temperature

R is Gas constant having value = 0.0821 L.atm/K.mol

Applying the equation as:

135 atm × 200 L = n × 0.0821 L.atm/K.mol × 297.15 K

⇒n = 1106.7381 moles

<u>For helium gas:</u>

Molar mass = 4 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$1106.7381= \frac{Mass}{4}$

$Mass= 4426.9524\ g$

<u>For hydrogen gas:</u>

Molar mass = 2 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$1106.7381= \frac{Mass}{2}$

$Mass= 2213.4762\ g$

Aqueous hydrochloric acid reacts with aqueous sodium sulfite to form aqueous sulfurous acid and aqueous sodium chloride . Write

snow_lady [41]

Answer:

Balanced reaction: $Na_{2}SO_{3}(aq)+2HCl(aq)\rightarrow H_{2}SO_{3}(aq)+2NaCl(aq)$

Explanation:

It is an example of double displacement reaction.
Here anions and cation of two reagents interchange between themselves.

2 molecules of HCl (hydrochloric acid) reacts with 1 molecule of $Na_{2}SO_{3}$ (sodium sulphite) to produce 2 molecules of NaCl (sodium chloride) and 1 molecule of $H_{2}SO_{3}$ (sulphurous acid)
Balanced reaction: $Na_{2}SO_{3}(aq)+2HCl(aq)\rightarrow H_{2}SO_{3}(aq)+2NaCl(aq)$
