Which element is used as rat poison and is found in the title of the?
Explanation : Arsenic and old lace is used in rat poison and is found in the title of the murder mystery. Arsenic is a poisonous element.
What acid is in rat poison?
Today, strychnine is used primarily as a pesticide, particularly to kill rats. Uncommonly, strychnine is found mixed with “street” drugs such as LSD, heroin, and cocaine.
What element is used in poisons to kill rats and insects?
Metal phosphides have been used as a means of killing rodents and are considered single-dose fast acting rodenticides (death occurs commonly within 1–3 days after single bait ingestion). A bait consisting of food and a phosphide (usually zinc phosphide) is left where the rodents can eat it.
What element is used in flares?
As magnesium ignites easily in air and burns with a bright light, it’s used in flares, fireworks and sparklers.
Do flares stay lit underwater?
Do flares work underwater? Yes they do work underwater and they work under the principle of oxidation. As you might know, most Alkali metals react violently with water. There used to be a time where the thought of using sodium as the oxidizer was pondered upon.
Do flares burn underwater?
A: Sure, a signal flare will burn on the moon, but you have to make a special one. The flare has to have both the material that burns (usually magnesium, which burns very brightly), and oxygen. The underwater olympic torch was designed to burn for about 3 minutes underwater.
Does magnesium burn underwater?
In what way and in what form does magnesium react with water? Magnesium fires cannot be extinguished by water. Magnesium continues to burn after oxygen is depleted.
How does a flair stay lit underwater?
The oxidizer is the oxygen in the surrounding atmosphere. These two ingredients can sustain a candle flame. The combustible gas, which might be hydrogen or acetylene, depending on the application, can be combined with oxygen gas (the oxidizer) to produce an underwater flame at the tip of the torch.
Can magnesium burn underwater?
How do flares stay lit underwater?
When the oxidizer reacts with heat, it releases its own oxygen. This means that flares don’t have to pull in oxygen from the space around them. they use the oxygen released from the chain reaction of the solid fuel and oxidizer, keeping the flare lit on land or under water.
Does magnesium burn without oxygen?
Without oxygen, the fire triangle is broken and the fire will go out. Magnesium is above carbon in the reactivity series and so can remove oxygen from carbon dioxide and continue to burn.
