Answer:Thermal energy comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature. Heat energy is another name for thermal energy. Kinetic energy is the energy of a moving object. As thermal energy comes from moving particles, it is a form of kinetic energy
Explanation:
The awnser is D beacuse the lower in group one you get the more reactive with water
Answer:
you were correct from my point of view but you could add a few zero's
Explanation:
i don't see how the was wrong
33000 Grams/Milliliters (g/mL) = 33,000,000 Milligrams/Milliliter (mg/mL)
1 g/mL = 1,000 mg/mL
1 mg/mL = 0.001000 g/mL
Answer:
Lone pairs and bonding pairs
Explanation:
The electron domain around the central atom includes
- All lone pairs on the central atom
- All bonding pairs between the central atom and the atoms directly attached to it
Double and triple bonds count as single domains.
Thus, the nitrite ion has three electron domains:
- A lone pair
- An N-O single bond
- An N-O double bond
It will take 25 days for this substance to become 1gram from 32 grams.
<h3><u>Explanation</u>:</h3>
Radioactivity or radioactive decay is the process of formation of different element from one Radioactive element due to decay of the radioactive nucleus. The radioactive decay is a first order kinetic reaction. This reaction has a straight log C vs T graph.
Here in this particular reaction, the half life of the radioactive substance is 5 days. So within 5 days, the concentration of the substance becomes halved.
Now, in the sample the amount of substance present = 32 grams
The final amount of this sample = 1 grams.
So number of half lives needed for this decay = 5 half lives.
So number of days required for this decay =
=25.
So within 25 days, 32 grams of the substance becomes 1grams.
