Answer:

IIron is the 26th element on the periodic table. It is located in period 4 and group 8. And for the properties, iron, like other metals, conducts heat and electricity, has a luster, and forms positive ions in its chemical reactions. Pure iron is fairly soft and can easily be shaped and formed when hot. Its color is silvery white. Iron is easily magnetized.

Classify the chemical equations as being balanced or not balanced. 2CO 2NO → 2CO2 N2 6CO2 6H2O → C6H12O6 O2 H2CO3 → H2O CO2 2Cu
marissa [1.9K]

Answer:

2CO 2NO → 2CO2 N2 : Balanced

6CO2 6H2O → C6H12O6 : Unbalanced

H2CO3 → H2O CO2 : Balanced

2Cu O2 → CuO : Unbalanced

Explanation:

1.) 2CO 2NO → 2CO2 N2

2 Carbon 2

4 Oxygen 4

2 Nitrogen 2

The amount of atoms of each element on each side of the equation are the same therefore the equation is balanced.

2.) 6CO2 6H2O → C6H12O6 O2

6 Carbon 6

12 Oxygen 8

12 Hydrogen 12

The amount of oxygen atoms is different on both sides of the equation therefore the equation is not balanced.

3.) H2CO3 → H2O CO2

2 Hydrogen 2

1 Carbon 1

3 Oxygen 3

The amount of atoms of each element is the same on both sides of the equation therefore the equation is balanced.

2Cu O2 → CuO.

2 Cu 2

2 O 1

The amount of oxygen atoms is different on both sides of the equation therefore the equation is not balanced.

A carbon forms one bond to an X atom plus three more bonds to three hydrogen atoms. If the hybridization to X has 81% p-characte
liraira [26]

Answer:

110 degree

Explanation:

This is because Hybridization of an s orbital with all three p orbitals (px , py, and pz) results in four sp3 hybrid orbitals. sp3 hybrid orbitals are oriented at bond angle of 109.5 degrees from each other. This 109.5 degrees gives an arrangement of tetrahedral geometry

What is the balanced NET ionic equation for the reaction when aqueous Cs₃PO₄ and aqueous AgNO₃ are mixed in solution to form sol
rusak2 [61]

Answer:

PO_4^{3-}(aq)+3Ag^+(aq)\rightarrow Ag_3PO_4(s)

Explanation:

Hello!

In this case, since the net ionic equation of a chemical reaction shows up the ionic species that result from the simplification of the spectator ions, which are those at both reactants and products sides, we take into account that aqueous species ionize into ions whereas liquid, solid and gas species remain unionized. In such a way, for the reaction of cesium phosphate and silver nitrate we can write the complete molecular equation:

Cs_3PO_4(aq)+3AgNO_3(aq)\rightarrow Ag_3PO_4(s)+3CsNO_3(aq)

Whereas the three aqueous salts are ionized in order to write the following complete ionic equation:

3Cs^+(aq)+PO_4^{3-}(aq)+3Ag^+(aq)+3NO_3^-(aq)\rightarrow Ag_3PO_4(s)+3Cs^+(aq)+3NO_3^-(aq)

In such a way, since the cesium and nitrate ions are the spectator ions because of the aforementioned, the net ionic equation turns out:

PO_4^{3-}(aq)+3Ag^+(aq)\rightarrow Ag_3PO_4(s)

Best regards!

Assuming that sea water is a 3.5 wt % solution of NaCl in water, calculate its osmotic pressure at 20°C. The density of a 3.5% N
olga nikolaevna [1]

Answer:

π = 14.824 atm

Explanation:

wt % = ( w NaCL / w sea water ) * 100 = 3.5 %

assuming w sea water = 100 g = 0.1 Kg

⇒ w NaCl = 3.5 g

osmotic pressure ( π ):

  • π = C NaCl * R * T

∴ T = 20 °C  + 273 = 293 K

∴ C ≡ mol/L

∴ density sea water = 1.03 Kg/L....from literature

⇒ volume sea water = 0.1 Kg * ( L / 1.03 Kg ) = 0.097 L sln

⇒ mol NaCl = 3.5 g NaCL * ( mol NaCL / 58.44 g ) = 0.06 mol

⇒ C NaCl = 0.06 mol / 0.097 L = 0.617 M

⇒ π = 0.617 mol/L * 0.082 atm L / K mol * 293 K

⇒ π = 14.824 atm
