MgCl₂(aq) + 2LiOH(aq) = Mg(OH)₂(s) + 2LiCl(aq)

Mg²⁺ + 2Cl⁻ + 2Li⁺ + 2OH⁻ = Mg(OH)₂ + 2Li⁺ + 2Cl⁻

Mg²⁺ + 2OH⁻ = Mg(OH)₂         <span>the net ionic equation</span>

You have the same two resistors on a 10 volt series circuit. Will the voltage going into the second resistor be more, less, or t
Keith_Richards [23]

both resistance will have same voltage across it which is equal to 5 volt.

if resistance value is different then voltage drop across them will be different.

current in both resistance would be same.

let's say resistance is 5 ohm of each one.

total current = total voltage / total resistance

= 10 /(5+5) = 10/10 = 1 amp

now voltage across 5 Ohm resistance = current × resistance = 1× 5 = 5 volt

A 5.00g piece of metal is heated to 100.0°C, then placed in a beaker containing 20.0 of water at 10.0°C. The temperature of the
Ahat [919]
Answer:

This metal has a specific heat of 0.9845J/ g °C

Explanation:
Step 1: Given data
q = m*ΔT *Cp
⇒with m = mass of the substance
⇒with ΔT = change in temp = final temperature T2 - initial temperature T1
⇒with Cp = specific heat (Cpwater = 4.184J/g °C) (Cpmetam = TO BE DETERMINED)

Step 2: Calculate specific heat
For this situation : we get for q = m*ΔT *Cp
q(lost, metal) = q(gained, water)

- mass of metal(ΔT)(Cpmetal) = mass of water (ΔT) (Cpwater)
-5 * (15-100)(Cpmetal) = 20* (15-10) * (4.184J/g °C =
-5 * (-85)(Cpmetal) = 418.4

Cpmetal = 418.4 / (-5*-85) = 0.9845 J/g °C

This metal has a specific heat of 0.9845J/ g °C

Which is the Net Ionic Equation for:
arlik [135]

Answer: 2Fe^{3+}(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+2Fe(s)

Explanation:

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

Net ionic equation : In the net ionic equations, we do not 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 complete balanced ionic equation will be:

2Fe^{3+}(aq)+6Cl^-(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+6Cl^-(aq)+2Fe(s)

 In this equation, Cl^- are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be:

2Fe^{3+}(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+2Fe(s)
