A sample of nitrogen gas is stored in a 489.6 mL flask at 108 kPa and 10.0°C. The gas is transferred to a 750.0 mL flask at 28.7

Wewaii [24]

Answer:

P2= 125.26 Kpa

Explanation:

V1= 489.6 ml=0.4896L

V2= 750 ml= 0.750L

V1= 180 KPa= 180000 Pa

P2= ?

T1= 10 = 10 + 273.15 = 283.15K

T2= 28.7+273.15= 301.85K

180000Pa* 0.4896L/ 283.15K * 301.85K/0.75L

P2= 12526.28553

P2= 125.26 KPa

Consider the reaction between no and cl2 to form nocl: 2no(g)+cl2(g)⇌2nocl(g) a reaction mixture at a certain temperature initia

AlladinOne [14]

Answer:

Kc = 0.402.

Explanation:

We can calculate Kc from the relation: Kc = [NOCl]² / [NO]²[Cl₂].

[NOCl] = 0.30 M, [NO] = 0.65 M, and [Cl₂] = 0.53 M.

Now, we can get Kc:

Kc = [NOCl]² / [NO]²[Cl₂] = (0.30 M)² / [(0.65 M)².(0.53 M)] = 0.402.

Sort these elements into pairs that would most likely exhibit similar chemical properties. It doesn't matter which pair goes in

nikklg [1K]

<em>Answer:</em>

Na = Rb
Ne = Kr
O = Se

<em>Explanation:</em>

According to modern periodic table, the elements present in same group have same chemical properties , because they same valence shell electrons.

As these both elements are present in group one, so these are called Alkali metals. Almost all alkali metal have same chemical properties.

Both these elements are present in group 18, called as noble gases.
They have same chemical properties like both are stable and are inert.

Both elements are present in group 16.
Both have same chemical properties.
Both have same valence shell electrons.

1.1.2 Differentiate between a micro and macro mineral element,<br>

nekit [7.7K]

Explanation:

<h3>Macro minerals are present at larger level in the animal body or required in large amount in the diet. Such as calcium, chlorine, magnesium, potassium, sulphur, and sulfur.</h3><h3>Micro minerals are often referred to as trace minerals i.e; they are present at low levels in the body and required in smaller amounts in the animal diet. Such as zinc, iron, iodine, cobalt, copper, flurion, etc.</h3>
