Flammable liquids are those that have a flashpoint of:.

Answers

Answer:

Flammable liquid is any liquid having a flashpoint at or below 199.4 °F (93 °C).

Explanation:

:)

Flashpoints for flammable liquids are at 100°F. Lower flash points allow for easier ignition of liquids. A liquid's flash point is the lowest temperature at which a concentrated enough layer of vapor accumulates on top of its surface to allow for ignition.

A liquid that is flammable has a flash point* below 37.8 ° C (100 ° F). A flammable liquid has a flash point that ranges from 37.8 to 93.3° C (100 to 200° F), which is above the standard working temperature. Flammable liquids emit a vapor that, at standard working temperatures, is easily ignitable.

The substance ignites more readily the lower the flash point. For instance, petrol is more flammable than ethylene glycol and has a flash point of about -40 degrees C (-40 °F).

The type of carbon fixation stores carbon dioxide in acid form is CAM i.e. crassulacean acid metabolism.

What are CAM?

CAM stands for crassulacean acid metabolism in this process photosynsthesis is occured at day time but the exchange of gases takes place at night itself only.

In this carbon fixation process, carbon dioxide is stored in the form of organic acid malic acid and losses carbon dioxide at the night time and by doing this it helps in the storage of water.

If 40mL of 2.50M HCl neutralizes 500ml. of KOH, what is the molarity of the KOH?

Answers

The molarity of the 500 mL KOH solution needed to neutralize the 40 mL of 2.50 M HCl is 0.2 M

Balanced equation

HCl + KOH —> KCl + H₂O

From the balanced equation above,

The mole ratio of the acid, HCl (nA) = 1

The mole ratio of the base, KOH (nB) = 1

How to determine the molarity of KOH Volume of acid, HCl (Va) = 40 mLMolarity of acid, HCl (Ma) = 2.5 MVolume of base, KOH (Vb) = 500 mL Molarity of base, KOH (Mb) =?

MaVa / MbVb = nA / nB

(2.5 × 40) / (0.15 × Vb) = 1

100 / (Mb × 500) = 1

Cross multiply

Mb × 500 = 100

Divide both side by 500

Mb = 100 / 500

Mb = 0.2 M

Thus, the molarity of the KOH solution needed is 0.2 M
