Answer:

Unit conversion between Rankine and Kelvin is linear.

Unit conversion between degree Celsius and degree Fahrenheit is linear.

Explanation:

Relation between rankine and Kelvin is

$R\ =\ \dfrac{9}{5}\ K$

So, the plot between Rankine and Kelvin is a straight line with zero intercept and has a slope having value $\dfrac{9}{5}$ .

Relation between degrees Celsius and degrees Fahrenheit is given by

$^{\circ}C\ =\ \dfrac{5}{9}\ (^{\circ}F\ -\ 32)$

So, the plot between degrees Celsius and degrees Fahrenheit is a straight line with slope $\dfrac{5}{9}$ and negative intercept of $\dfrac{160}{9}$ .

Which feature of four different marine fossils makes the fossil organism most similar to the present-day organism with four limb

zvonat [6]

I found the rest of the exercise on the internet and these are the options.
"-Undifferentiated vertebrae throughout the body.
-One neck vertebra allowing up and down movement.
-Many neck vertebrae that allow for greater mobility.
<span>-Two neck vertebrae allowing up and down and sideways movement."

The correct answer would be the third. - "</span>Many neck vertebrae that allow for greater mobility." The <span>present-day organism with four limbs has a neck with several vertebrae that allow movements of rotation (mostly because of only two vertebrae at the top of the neck), and side way movements, as well as back and forth movements.</span>

How many magnesium ions are present in 5.36 x 10-4 mol of magnesium iodide?

WARRIOR [948]

Magnesium iodide = MgI₂
mass of Mg = 24.3g
mass of I = 126.9g
mass of MgI₂ = 24.3 + 2*126.9 = 278.1g = 1 mole

in 5.36x10⁻⁴ mole of MgI₂ ---------------- x g of Mg
in 1 mole of MgI₂ ------------------------------ 1 mole of Mg
x = 5.36x10⁻⁴ moles of Mg = 0.000536 moles of Mg

answer: we've 0.000536 moles of Mg (magnesium ions) in 5.36x10⁻⁴ moles of MgI₂
