The answer is rubidium -91 because it takes a shorter time of 58.4 seconds to become stable.
Answer:
electrons
Explanation:
protons and neutrons are found in the nucleus while electrons are outside the nucleus
- By changing three atom bond angle , we can change molecular polarity. if bond angle is 120° and all atom has same electronegativity, the resultant polarity ( dipole moment ) become zero. we can change bond anngle either less than or greater than 120°, but not exactly 120
- Replacing one or more atom with different atoms having electro negativity values also make molecular poles.
- By placing molecules under external electric field or magnetic field also causes to the molecule.
The correct option is D.
Mole is a measurement used in chemistry which allows us to measure out the same quantity of matter in different substances. Mole allows scientist to measure two substances, for instance, magnesium and sodium, which have equal amount of atoms. Thus, a mole of magnesium contains the same number of atoms as a mole of sodium.
Answer:
is a combustion reaction
Explanation:
The reaction is a combustion since you have a hydrocarbon reacting with oxygen to form water and carbon dioxide.
The balanced equation is:
