30 degrees from the mirror's surface
pretty sure It's correct and if it is then your welcome
Protons = +1
negatrons = -1
neutrons = 0
<span>electrons = -1
</span>
<span>negatrons are like positrons and they are subatomic particles and are not present in atoms
</span>
so electrons are negatively charged and are present in atoms
hope that helps
It is generally referred to as ‘Steam’
Hope this helps and have a happy Friday!
Answer:
moles
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to molecular mass , occupies 22.4 L at STP and contains avogadro's number
of particles.
To calculate the moles, we use the equation:
Given mass of ethanol = 0.2301
Molar mass of ethanol = 46.07 g/mol
Thus there are
moles of ethanol are present in the sample.
