hydrogen-2 is also known as deuterium as well as hydrogen-3 is known as tritium hydrogen-1 is our common hydrogen isotope a samp

UkoKoshka [18]

H-1 only has 1 proton and 1 electron, so its mass number is 1.
H-2 has one more neutron so its mass number is 2
H-3 has one more neutron than H-2 so its mass number will be 3.
average atomic mass = 1 x 99% + 2 x 0.8% + 3 x 0.2%
=1.012

How might a molecule with two strong bond dipoles have no molecular dipole at all?

Reil [10]

A molecule with two strong bond dipoles can have no molecular dipole if the bond dipoles cancel each other out by pointing in exactly opposite directions. For example, in carbon dioxide (a linear molecule), the carbon-oxygen bonds have a <span>large dipole moment. However, because one dipole points to the left and the other to the right the dipole is cancelled.</span>

Is h2so4 a Arrhenius acid

MAVERICK [17]

Answer : Yes , H2SO4 is an arrhenius acid

<h2>Explanations : </h2>

• An ,Arrhenius acid ,is a substance that ,dissociates, in water to form ,hydrogen ions (H+).

• In other words, an arrhenius acid increases the H+ ion concentration in aqueous solution.

• This can be represented by the equation :

$H_SO_4^{-\text{ }}\rightleftarrows H^{+\text{ }}+SO_4^{2-}$

• Therefore, H2SO4 is a strong arrhenius acid.

How many grams of solid NaOH are required to prepare a 400ml of a 5N solution? show your work!

Nuetrik [128]

<u>Answer:</u> The mass of solid NaOH required is 80 g

<u>Explanation:</u>

Equivalent weight is calculated by dividing the molecular weight by n factor. The equation used is:

$\text{Equivalent weight}=\frac{\text{Molecular weight}}{n}$
