Answer:
Explanation:
PV / RT = n , n is number of moles
Total pressure = 96400 Pa
vapour pressure = 23.8 mm of Hg
= .0238 x 13.6 x 10³ x 10 Pa = 3236.8 Pa
Pressure of hydrogen gas P = 96400 - 3236.8
= 93163.2 Pa
n = 93163.2 x .0251 / 8.31 x 298
= .944 moles of hydrogen gas is produced
moles of magnesium reacted = .944
grams of magnesium reacted = .944 x 24 = 22.66 grams .
Answer:
Option (D)
Explanation:
A stream is a narrow river that originates from a source area. These source areas are usually the high altitude mountains in which the high amount of snow is gathered in the winter season and subsequently melts during the summer season. As a result of which the streams and rivers flows and mix up with the seas and oceans. These source areas are commonly termed as the headwaters or the stream head.
The direction towards the headwaters of a stream or moving against the flow direction is generally known as the upstream direction.
Hence, the correct answer is option (D).

Answer :
Incorrect
Explanation : In the given solution set of Ax = b;
is set of all vectors to form w=
p +
here
is is any solution of the equation Ax = 0;
this stands to be incorrect, as the correct would only exists when some vector
p is found to be like this
Ap=b
