Oxygen is killing us This isnt for science this is real talk the reason oxygen kills us because it damages our cells as we dont
siniylev [52]
I can tell you're not very educated because everyone knows that breathing pure oxygen for long periods of time can sometimes hurt us. Oxygen in lower levels, such as levels found in atmosphere are just right for us to breathe. Get a life and stop trying to scare young kids that just want help on their homework.

What is the definition of a common ion as it applies to Le Chatelier’s principle?
navik [9.2K]
The definition of a common ion as it applies to Le Chatelier's principle is an ion that is present in an equilibrium system and a compound added to the system. This is the case since in Le Chatelier's principle, it is based on an equilibrium system and where the reaction shifts to the left or to the right; towards the products or the reactants side.

Enter the net ionic equation, including phases, for the reaction of AgNO3(aq) with K2SO4(aq). Solubility Rules are found here.
wel
<span>In ionic equations, the chemicals are written as the ions which are dissolved in water.
 
AgNO</span>₃<span>(aq) reacts with K</span>₂<span>SO</span>₄<span>(aq) and produces Ag</span>₂<span>SO</span>₄<span>(s) and KNO</span>₃<span>(aq). The balanced complete ionic reaction is
2Ag</span>⁺<span>(aq) + NO</span>₃⁻<span>(aq) +2K</span>⁺<span>(aq) + SO</span>₄²⁻<span>(aq) → Ag</span>₂<span>SO</span>₄<span>(s) +2K</span>⁺<span>(aq) + NO</span>₃⁻<span>(aq)
 
K</span>⁺<span>(aq) and NO</span>₃⁻<span>(aq) present in both sides. Hence, we can cut off them to find net ionic equation. So, net ionic equation is
2Ag⁺(aq) + SO₄</span>²⁻<span>(aq) → Ag₂SO₄(s)</span>

A gas system has volume, moles and temperature of 9040 mL, 0.447 moles and -35.50 oC, respectively. What is the pressure in atm?
babymother [125]

Answer : The pressure of the gas is, 0.964 atm

Solution : Given,

Volume of gas = 9040 ml = 9.040 L        (1 L = 1000 ml)

Moles of gas = 0.447 moles

Temperature of gas = -35.50^oC=237.5K       (0^oC=273K)

Using ideal gas equation,

PV=nRT

where,

P = pressure of the gas

V = volume of the gas

T = temperature of the gas

n = number of moles of gas

R = gas constant = 0.0821Latm/moleK

Now put all the given values in this formula, we get the pressure of the gas.

P(9.040L)=(0.447moles)\times (0.0821Latm/moleK)\times (237.5K)

By rearranging the terms, we get

P=0.964atm

Therefore, the pressure of the gas is, 0.964 atm
