The daughter isotope (a decay product)of O-15 = N-15(Nitrogen 15)
<h3>Further explanation
</h3>
Radioactivity is the process of unstable isotopes to stable isotopes by decay, by emitting certain particles,
- alpha α particles ₂He⁴
- beta β ₋₁e⁰ particles
- gamma particles γ
- positron particles ₁e⁰
O-15 emits positron particles ₁e⁰, so the atomic number decreases by 1, the mass number is the same
Reaction
The mass number of the daughter isotope = 15, atomic number = 7
If we look at the periodic system, the element with atomic number 7 is Nitrogen (N)
°C = (°F - 32)/1.8
°C = (-143-32)/1.8
°C = -97.22
hope this helps :) (please mark brainliest if correct!)
yes I doso u need to find the amount of grams total and the individual amount of grams.so 40+40+52+16+16+16+16=196g (I got the numbers from the periodic table)K- 80gCr-52gO-64gsince you are solving for oxygen, you would only use the oxygen part so...64g/196g=32.9%32.9% is the answer hope this helps! if it doesn't, let me know in the comments! have a blessed day!
Explanation:
- Polar molecule are soluble in polar solvents
- Non polar molecules are soluble in non polar solvents.
Stearic acid is an organic acid composed of seventeen carbons with one carboxylic acid group in the end. Its chemical formula is . The hydrophobic part is this chain is made up of 17 carbon atom and hydrophilic part is only of made up of carboxylic group due to which it won't get dissolve in water.Which means that stearic acid will get dissolve in non polar solvent that is hexane. Hence, stearic acid is non polar molecule.
Where as sucrose an organic molecule with molecular formula of .Due to presence of polar hydroxyl(-OH) groups in molecule , molecule will get easily dissolve in polar solvent that is water. Since,the hydrophobic part in the molecules are covered by the hydrophilic part due to which it gets easily dissolve in water. Hence, the sucrose in polar molecule.
