Answer : The complete ionic equation in separated aqueous solution will be,

$Cu^{2+}(aq)+SO_4^{2-}(aq)+Zn^{2+}(aq)+2NO_3^{-}(aq)\rightarrow Cu^{2+}(aq)+2NO_3^{-}(aq)+ZnSO_4(s)$

Explanation :

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The balanced molecular equation will be,

$CuSO_4(aq)+Zn(NO_3)_2(aq)\rightarrow Cu(NO_3)_2(aq)+ZnSO_4(s)$

The complete ionic equation in separated aqueous solution will be,

$Cu^{2+}(aq)+SO_4^{2-}(aq)+Zn^{2+}(aq)+2NO_3^{-}(aq)\rightarrow Cu^{2+}(aq)+2NO_3^{-}(aq)+ZnSO_4(s)$

It would (probably) be:
CuSO4 + Zn(NO3)2 -> Cu(NO3)2 + ZnSO4

Given that the molar mass of carbon is 12 g/mol and the molar mass of oxygen is 16 g/mol, calculate the molar mass of carbon dio

nekit [7.7K]

Molar mass of oxygen is:
M(O)=16 g/mol
Molar mass of carbon is:
M(C)=12 g/mol
Molar mass of carbon dioxide is:
M(CO2)=M(C)+2*M(O)
M(CO2)=12 g/mol+2*16g/mol
M(CO2)=44 g/mol

Molar mass(M) is the mass of 1 mole of the substance (grams per mole of a compound).

HELP ME dm me on insta temi.awolola I need a lot of help

Georgia [21]

Protons:

- Have a mass

- Positively charged

- Found inside the nucleus of an atom

Electrons:

- Have a mass. (9.10938188×10−31 kilograms), though this can sometimes be considered negligible due to how small that actually is. Barely factored into atomic mass

- Negatively charged

- Found outside the nucleus in the electron shell

Neutrons:

- Have a mass

- Neutral (no charge)

- Found inside the nucleus of an atom

Atom A:

- 1 proton

- 0 Neutrons

- 1 electron

- Atomic mass of 1

- Atomic number of 1

Atom B:

- 8 Protons

- 10 Neutrons

- 8 electrons

- Atomic mass of 18

- Atomic number of 8

Atomic mass includes the number of protons and neutrons in the nucleus. Atomic number is the number of protons, as this is what defines what type of element the atom is.

onvert the value of Kc to a value of Kp for the following reaction: N2(g)+3H2(g)⇌2NH3(g) Kc = 0.50 at 400 °C.

ale4655 [162]

Answer:

$K_p= 0.00016$

Explanation:

The relation between Kp and Kc is given below:

$K_p= K_c\times (RT)^{\Delta n}$

Where,

Kp is the pressure equilibrium constant

Kc is the molar equilibrium constant

R is gas constant

T is the temperature in Kelvins

Δn = (No. of moles of gaseous products)-(No. of moles of gaseous reactants)

For the first equilibrium reaction:

$N_2_{(g)}+3H_2_{(g)}\rightleftharpoons2NH_3_{(g)}$

Given: Kc = 0.50

Temperature = $400^oC=[400+273]K=673K$

R = 0.082057 L atm.mol⁻¹K⁻¹

Δn = (2)-(3+1) = -2

Thus, Kp is:

$K_p= 0.50\times (0.082057\times 673)^{-2}$

$K_p= 0.00016$

Describe the appearance of the material. Include its color and state (solid or liquid). Pour ¼ cup of water into a small, clear

Alex777 [14]

Answer:

Here the given material is taken and mixed with water.

Explanation:

The amount of material and water taken are same. Hence if it is not soluble in water it should make a dense and flowy paste like material and if it is soluble in water it should this and thicker density of water should remain.

If the amount of water that we are taking is more than the material will float in water if it is not soluble and lighter than water or would sink if it is heavier than water.
