Answer:

The pressure is 16, 9 atm

Explanation:

We use the formula PV=nRT. The temperature in Kelvis is: 273 + 25 = 298K

PV=nRT  P =(nRT)/V

P= (0, 450 mol x 0,082 l atm/K mol x 298)/0,650 l= 16, 91723077atm

Gekata [30.6K]

Answer: Scientific reasoning

Explanation:

A scientific reasoning can be defined as the justification which connects the evidence with that of the claim and it rules out all those claims that are not supported by any evidence. It explains the fact that how evidence can support a claim and scientifically acceptable conclusion can be drawn. An argument is always based on one or more claims which can either be true or evidentially proved.

Part A
den301095 [7]

Answer:

n_{Cl_2}=0.3molCl_2

Explanation:

Hello there!

In this case, according to the given chemical reaction whereas the sodium chloride is in a 2:1 mole ratio with chlorine, the required moles of the later are computed as shown below:

n_{Cl_2}=0.6molNaCl*\frac{1molCl_2}{2molNaCl}

So we cancel out the moles of NaCl to obtain:

n_{Cl_2}=0.3molCl_2

Best regards!

When aqueous solutions of AgNO 3 and KI are mixed, AgI precipitates. The balanced net ionic equation is ________. Ag (aq) I- (aq
dimulka [17.4K]

Answer:

Ag⁺(aq) + Cl⁻(aq) ==> AgCl(s)

Explanation:

The net ionic equation can be described as the equation that contains only those species which would be participated in the chemical reaction. The spectator ions are the type of the ions that are present in both sides of the chemical equation these ions could not be present in the net ionic equation

First, it is easiest if you write the compete molecular equation:

AgNO₃(aq) + KCl(aq) ⇔ AgCl(s) + KNO₃(aq)

we look up which compounds are soluble (aq) and which are not (s). In this case, silver chloride (AgCl) is not soluble.  Thus, the net ionic equation is...  

Ag⁺(aq) + Cl⁻(aq) ==> AgCl(s)
