Usually, the more something ionizes, the better it conducts electricity. NH3 is molecular. CH3OH is an alcohol and doesn't ionize well. I'd say MgCl2 was more ionizable than H2O2, just because it's less likely to cause metathesis.

A sample may contain any or all of the following ions: Hg22+, Ba2+, Mn2+. No precipitate formed when an aqueous solution of NaCl
Bess [88]

Answer:

Only Mn⁺² is present.

Explanation:

  • When an aqueous solution of NaCl is added, the Cl⁻ species is introduced. In the presence of Cl⁻, Hg₂²⁺ would precipitate as Hg₂Cl₂.
  • When an aqueous solution of Na₂SO₄ is added, the SO₄⁻² species is introduced. In the presence of SO₄⁻², Ba⁺² would precipitate as BaSO₄.

No precipitate formed when either of these solutions were added, thus <u>the sample does not contain Hg₂⁺² nor Ba⁺²</u>.

  • Under basic conditions Mn⁺² would precipitate as Mn(OH)₂. A precipitate formed once the solution was made basic, so <u>the sample contains Mn⁺²</u>.

IRISSAK [1]

Answer:

\large \boxed{\text{1. Veins; 2. 600 W; 3. 45 N}}

Explanation:

1. Arteries are the tubes responsible for  the movement of blood from the heart to other parts of the body.

2. Power

(a) Work performed

w = mgh = 12 kg × 9.807 m·s⁻² × 15 m = 1800 J

(b) Power level

P = w/t = 1800 J/3 s = 600 W

3. Machine load

The formula for mechanical advantage (MA) is

MA = \dfrac{F_{o}}{ F_{e}}

where

Fₒ = the force of the object

Fₑ = the force exerted to overcome that of the object

\begin{array}{rcl}MA & = &\dfrac{F_{o}}{ F_{e}}\\\\6 & = &\dfrac{F_{o}}{ \text{7.5 N}}\\\\F_{o} & = & \text{45 N}\\\end{array}\\\text{The machine can carry a maximum load of $\large \boxed{\textbf{45 N}}$}

Fatty acid with only single covalent bonds is said to be
ohaa [14]
These are known to be saturated.  
The definition of a saturated fatty acid is that the carbon chain coming off of the acid group contains only single bonds.  An unsaturated fatty acid contains at least one double bond in the carbon chain coming off of the acid group.  Saturated fats are usually fats (solid at room temperature) while unsaturated fats can be oils (liquid at room temperature) this is because the single bonds in the saturated fats give the molecule a shape that can stack on another saturated fat molecule more easily which makes the melting points higher.  The double bonds (usually referring to cis double bonds since trans double bonds are in trans fats) in unsaturated fats give the molecule a shape that cannot stack on another unsaturated fat molecule easily which makes the melting point lower.

I hope this helps.  Please let me know if anything is unclear or if you want further explanation.
