CH4+ (2)O2—CO2+ (2)H2O
1 C 1
4 H 2 > 4
4 < 2 O 3 > 4

You leave [C] alone and only focus on [O] and [H]
You’ll have to place 2 on the right side in front of H2O because there is a H4 on the left side
This makes H4 on the right side and O2 which then makes the total of [O] on the right side four
You then will need to place a 2 in front of O2 to make the total of [O] on the left side four as well

A ridged steel tank filled with 62.7L of nitrogen gas of 85.0L atm
mylen [45]

The final gas pressure : 175.53 atm

<h3>Further explanation</h3>

Maybe the complete question is like this :

A ridged steel tank filled with 62.7 l of nitrogen gas at 85.0 atm and 19 °C is heated to 330 °C while the volume remains constant. what is the final gas pressure?

The volume remains constant⇒Gay Lussac's Law  

<em>When the volume is not changed, the gas pressure in the tube is proportional to its absolute temperature  </em>

\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}

P₁=85 atm

T₁=19+273=292 K

T₂=330+273=603 K

\tt P_2=\dfrac{P_1\times T_2}{T_1}\\\\P_2=\dfrac{85\times 603}{292}\\\\P_2=175.53~atm

Assuming that the only lons contributing to the salt content in the Dead sea is Nat
marshall27 [118]

Answer:

3.37kg of NaCl is the salt content of the dead sea

Explanation:

A concentration of 33.7% means there are 33.7g of NaCl in 100mL of solution.

To solve this question we need to convert 10.0L to mililiters, and then, solve for the mass of NaCl in grams and convert it to kg:

<em>Volume in milliliters:</em>

10.0L * (1000mL / 1L) = 10000mL

<em>Mass of NaCl:</em>

10000mL * (33.7g NaCl / 100mL) = 3370g NaCl

<em>In kg:</em>

3370g * (1kg / 1000g) =

<h3>3.37kg of NaCl is the salt content of the dead sea</h3>

What is the effect of constant stirring on the solubility of solids and liquids?
vfiekz [6]

Stirring affects how quickly a solute dissolves in a solvent, but has no effect on how much solute will dissolve. The amount of solute that will dissolve is affected by temperature - more will dissolve at higher temperatures. This is called the solubility of the solute
