Answer:

A) Iron B) All of these metals are magnetic ones. Iron is the most magnetic one. C) Nickel

Explanation:

Magnetism varies on metals and non metals elements. There are five classes of Magnetism, and this classification is based on the magnetic moments of the atoms of element.

In crescent order:  

  1. Diamagnetic: Carbon, Gold Magnetic Moment below ranging from   small and negative susceptibility to magnetic.
  2. Paramagnetic Aluminum (small and positive  magnetic susceptibility) (1
  3. Antiferromagnetic  (small and positive magnetic susceptibility)
  4. Ferrimagnetic (mid and positive magnetic susceptibility)
  5. Ferromagnetic Iron, Nickel, Cobalt (mid and huge positive susceptibility).

A certain compound is made up of one carbon (c) atom, two bromine (br) atoms, and one oxygen (o) atom. what is the chemical form
padilas [110]
Answer:
           Chemical Formula  =  COBr₂

           Structural Formula  =  Attached Below

           IUPAC Name  =  Carbonic Dibromide

           Common Name  =  Bromophosgene

As we know Carbon has the tendency to form four covalent bonds, Oxygen can form two covalent bonds and Bromine can form a single bond. Keeping this in mind we can say that in given compound carbon is forming two single bonds with two bromine atoms and a double bond with oxygen atom. Therefore, the valencies of all elements in the given compound are satisfied and completed.

What entropy change is associated with the reversible phase change from 1.0kg of ice to water at 0 ° C?
avanturin [10]

Answer:

1200 J/K  

Explanation:

The formula for the entropy associated with a reversible phase change is

\Delta S= \dfrac{q_{\text{rev}}}{T}

1. Calculate q

For a reversible phase change like melting,

q_{\text{rev}} = m\Delta_{\text{fus}}H = \text{1000 g} \times \dfrac{\text{334 J}}{\text{1 g}} = \text{334 000 J}

2. Calculate ΔS

\Delta S = \dfrac{q_{\text{rev}}}{T} =\dfrac{\text{334 000 J}}{\text{273.15 K}} = \textbf{1200 J/K}

It takes 24.56 mL of a sodium hydroxide solution to precisely neutralize 2.023 g of potassium hydrogen phthalate (F.W. = 204.22g
Alinara [238K]

Answer:

0.4033 M is the concentration of the sodium hydroxide solution.

Explanation:

Mass of potassium hydrogen phthalate = 2.023 g

Molar mass of potassium hydrogen phthalate = 204.22 g/mol

Moles of potassium hydrogen phthalate :

= \frac{2.023 g}{204.22 g/mol}=0.009906 mol

C_8H_5KO_4+NaOH\rightarrow C_8H_4KO_4Na+H_2O

According to reaction, 1 mole of potassium hydrogen phthalate reacts with 1mole of NaOH. Then 0.009906 moles of potassium hydrogen phthalate  will recat with:

\frac{1}{1}\times 0.009906 mol=0.009906 mol of NaOH

Moles of NaOH = 0.009906 mol

Volume of NaOH solution = 24.56 mL = 0.02456 L

Molarity=\frac{Moles}{Volume (L)}

[NaOH]=\frac{0.009906 mol}{0.02456 L}=0.4033 M

0.4033 M is the concentration of the sodium hydroxide solution.
