Answer:
The answer is<u> NH3.
</u>
Explanation:
The N2H2 (O hydrazine) is formed when from the synthesis of ammonia and hydrogen peroxide.
Or also formed when a 1,000g sample of nitrogen is combined with a 7.2 x10∧-2 sample of hydrogen.
0.2160 of hydrogen is 3 times 7.2 x10∧-2.
It means that the compound would look like:
N2H6.
But in chemistry, if there are divisible numbers in a compound, they must be divided:
NH3.
4.) True:
Since
P(E) = 1 - P(Ec)
P(E)+P(Ec)=1
If you think of it as the chances of you getting e or not getting e, then it's a 100% chance of either one happening.
Answer:c
Explanation: it states that the atom is neutral, meaning the number of electrons and protons are the same. so if there are 13 electrons, there are 13 protons. And the mass number is neutrons plus protons. So 13+15 is 28
Answer: Option D is correct.
Explanation: Equation given by de Broglie is:
where, = wavelength of the particle
h = Planck's constant
m = mass of the particle
v = velocity of the particle
In option A, football will have some mass and is moving with a velocity of 25 m/s, hence it will have some wavelength.
In Option B, unladen swallow also have some mass and is moving with a velocity of 38 km/hr, hence it will also have some wavelength.
In Option C, a person has some mass and is running with a velocity of 7 m/hr, hence it will also have some wavelength.
As, the momentum of these particles are large, therefore the wavelength will be of small magnitude and hence, is not observable.
From the above, it is clearly visible that all the options are having some wavelength, so option D is correct.
