Answer:

number of moles of H_2=4.16mol

Explanation:

experiment data:

temperature= 22^{\circ}C=273+22 k=295k

pressure=1.007 atm

volume is missing so assuming volume-=100L

using ideal law relationship

ideal gas means gas which occupies negligible space and there is no interaction between the molecules of gases.

PV=nRT

put all the experimental data, we get

n=4.15 mol

number of moles of H_2=4.16mol

Answer:

U A G C C A U C G G A U C C G A U

Explanation:

In DNA, A=T, C=G, and vice versa. RNA has U instead of T. So dna to rna: adenine = uracil, thymine = adenine, cytosine = guanine, and guanine = cytosine.

John has to hit a bottle with a ball to win a prize. He throws a 0.4 kg ball with a velocity of 18 m/s. It hits a 0.2 kg bottle,
enot [183]

One can solve the problem by using the law of conservation of momentum. The total momentum prior to the collision must be equivalent to the total momentum after the collision, so we have:

m1v1 + m2v2 = m1v1 + m2v2

Here, m1 is 0.4 Kg that is the mass of the ball, u1 is 18 m/s that is the initial velocity of the ball, m2 is 0.2 Kg that is the mass of the bottle, and u2 is 0 that is the initial velocity of the bottle.

v1 is the final velocity of the ball, which is to be determined, and v2 is 25 m/s that is the final velocity of the bottle.

Substituting and rearranging the equation, one can find the final velocity of the ball:

v1 = m1u1 - m2v2 / m1 = (0.4 kg) (18 m/s) - (0.2 Kg) (25 m/s) / 0.4 Kg = 5.5 m/s.
