Answer:
A Neutron and a Hydrogen Atom
Explanation:
Hydrogen atom having an atomic mass of 1.008 amu consists of one proton and one electron. Hence, the +ve and -ve charges cancels out and makes the hydrogen atom a neutral specie.
Also, we know that neutron is neutral sub particle while, proton and electron are positively and negatively charged respectively. Therefore, a neutral neutron having no charge becomes equal to hydrogen atom having zero charge due to cancellation of both +ve and -ve charges.
Ammonium hydroxide aka ammonia is a colorless gas that smells awful.... ammonia contains nitrogen and hydrogen.... and also ammonia is used as a lifting gas, which means it cans be used to lift hot air balloons.... lol that was just a weird fact..... but have an amazing day/night and god bless u!
Answer:
-943J or 943J released
Explanation:
m=2.4 mol x 207.g/ mol=497.3g
c=.129 J/gC
T= T f-Ti=(22.5-37.2)=-14.7C
Q=?
Q=(49.3g)(.129 J/g C) (-14.7 C)
= -943 J or 943 J released
First put everything into the same measurements.
111 km = 111km
42mpg = 67.592kpg
1 U.K. Gallon = 4.546 liters
67.592/4.546 = 14.8684557853
42mpg = 14.87kpl (kilometers per liter)
1.10 euros/liter = 1.10 euros/liter
If you drive 111 km a day and go 14.87 km a liter, divide 111 by 14.87 to get about 7.46, which is how many liters you will use a day. Multiply the price, 1.10 euros, by the number of liters, 7.46, to get the daily price of gas, which is about 8.206 a day. Multiply by 7 (num of days in week) to get about 57.44
It cost about 57.44 euros for one week of gas.
I hope I'm not too late! And hopefully that is right! No guarantees lol
