Answer:
1. it is symbolized as 4/2 He
: Alpha rays
2. it has the weakest penetrating power
: Alpha rays
3. It is a high-speed electron
: beta rays
4. It possesses neither mass nor charge
: gamma rays
5. it has the strongest penetrating power
: beta rays
6. its is symbolized as 0/-1e
: beta rays
7. it is the most massive of all the components: alpha rays
Explanation:
Let us consider the characteristics of each of the given rays.
α rays: These are helium nucleus so are symbolized by 
Due to two protons and two neutrons unlike beta and gamma rays these are the most massive and thus have least penetrating power among the three given rays.
β rays: These are actually high speed electrons and are symbolized as 
. Due to lesser mass than alpha rays they are more penetrating than them however less penetrating than gamma rays.
γ rays : They carry no charge or mass. Due to least massive among the three rays they have highest penetrating power.
Machines that are fairly simple and make working easier
Carbon monoxide is a colorless, odorless, tasteless gas produced by burning gasoline, wood, propane, charcoal or other fuel. Improperly ventilated appliances and engines, particularly in a tightly sealed or enclosed space, may allow carbon monoxide to accumulate to dangerous levels.
TMS has 12 protons which are all equivalent and four carbons, which are also all equivalent. This means that it gives a single, strong signal in the spectrum, which turns out to be outside the range of most other signals, especially from organic compounds.
Answer:
A
Explanation:
Chemical compound
Lead(II) chloride is an inorganic compound which is a white solid under ambient conditions. It is poorly soluble in water. Lead(II) chloride is one of the most important lead-based reagents. It also occurs naturally in the form of the mineral cotunnite.
