el nitrogeno es un gas que se utiliza para conservar embriones,su temperatura es de -195,8ºc calcula esta temperatura en K y ºF

kipiarov [429]

Answer:
-195.8 °C = 77.35 K = -320.44 °F

Explanation:

Temperature is commonly measured in following three scales;

1) Kelvin

2) Fahrenheit

3) Celsius

Other scales are Rankine, Romer, Newton, Delisle e.t.c

Temperature given is -195.8 °C. Degree Celsius is related to Kelvin and Fahrenheit as follow,

Celcius to Kelvin;

K = °C + 273.15
So,
K = -195.8 + 273.15

K = 77.35

Celcius to Fahrenheit;

°F = °C × 9/5 + 32
So,
°F = -195.8 × 9/5 + 32

°F = -320.44

Molecule A is a __________. Bonding of fatty acids and polar phosphate groups to glycerol. Molecule A is a __________. Bonding o

Elena L [17]

Answer:

The correct option is: c. phospholipid

Explanation:

Phospholipids, also known as glycerophospholipids, are the derivatives of fatty acids which is a major structural component of the cell membranes.

Phospholipid is the class of lipids that is composed of a glycerol molecule that forms ester bonds with the two long-chain fatty acids and one phosphate group.

Therefore, Molecule A is a phospholipid.

The iodine "clock reaction" involves the following sequence of reactions occurring in a reaction mixture in a single beaker. 1.

Mars2501 [29]

C: 0.012 mol.

<h3>Explanation</h3>

Start with 0.0020 moles of iodate ions ${\text{IO}_{3}}^{-}$ .

How many moles of iodine $\text{I}_2$ will be produced?

${\text{IO}_{3}}^{-}$ converts to $\text{I}_2$ in the first reaction. The coefficient in front of $\text{I}_2$ is three times the coefficient in front of ${\text{IO}_{3}}^{-}$ . In other words, each mole of ${\text{IO}_{3}}^{-}$ will produce three moles of $\text{I}_2$ . 0.0020 moles of ${\text{IO}_{3}}^{-}$ will convert to 0.0060 moles of $\text{I}_2$ .

How many moles of thiosulfate ions ${\text{S}_2\text{O}_3}^{2-}$ are required?

$\text{I}_2$ reacts with ${\text{S}_2\text{O}_3}^{2-}$ in the second reaction. The coefficient in front of $\text{I}_2$ is twice the coefficient in front of ${\text{S}_2\text{O}_3}^{2-}$ . How many moles of ${\text{S}_2\text{O}_3}^{2-}$ does each mole of $\text{I}_2$ consume? Two. 0.0060 moles of $\text{I}_2$ will be produced. As a result, $2 \times 0.0060 = 0.0120$ moles of ${\text{S}_2\text{O}_3}^{2-}$ will be needed.
