I believe the closest possible answer to this question are:Gas A effuses faster than gas B.The molar mass is directly proportional to the rate of effusion.Thank you for your question. Please don't hesitate to ask in Brainly your queries
Air molecules are spaced far apart is the answer. Since air is a gas, it’s safe to say its particles are separated in random ranges and fits the statement well.
The answer would be non-polar covalent.
Bromine is a non-metal, making the bond covalent.
The bond is non-polar because there is no unequal sharing between electrons because both elements in the bond are the same; they have the sane electro negativities.
The molarity of the base ( ammonium hydroxide) is calculated as follows
find the moles of Nitric acid =molarity x volume
=29.5 x 0.175 =5.163 moles of nitric acid
write the equation for reaction
HNO3+ NH4OH =NH4NO3 +H2O
by use of mole ratio between HNO3 to NH4NO3 which is 1:1 the moles of NH4OH is also 5.163 moles
molarity =moles/volume
= 5.163 /50=0.103 M is the molarity of the base
Answer:
687.5 m
Explanation:
as the given speed (or velocity) is given as 12.5 m/s and time is 55 sec...
then total distance to be travelled in 55 secs= (12.5× 55) m = 687.5 m
