Protons-33
neutrons-42
electrons-33
As per the International System of Units is a form of metric system in which distance is expressed in meters.
The given distance is 45.2 cm
Convert centimeter (cm) to SI base unit (meter)
One hundred centimeters is equivalent to one meter
I.e. 100 cm = 1 m
Therefore, the given distance of 45.2 cm =
= 45.2 cm * 1 m/100 cm = 0.452 m
Thus, the correct SI base unit for 45.2 cm = 0.452 m
Answer:
lol there's no question girly but lmk if ya need help with anything.
Explanation:
The grams of N2 that are required to produce 100.0 l of NH3 at STP
At stp 1moles = 22.4 l. what about 100.0 L of NH3
= 100 / 22.4 lx1 moles = 4.46 moles of NH3
write the reacting equation
N2+3H2 =2NH3
by use of mole ratio between N2 to NH3 which is 1:2 the moles of N2 =4.46/2 =2.23 moles of N2
mass = moles x molar mass
= 2.23moles x 28 g/mol = 62.4 grams
