"an acid is a substance that forms hydrogen ions when dissolved in water." this is an example of —
LenaWriter [7]

Answer is: this is an example of an Arrhenius acid.

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

For example hydrochloric acid: HCl(aq) → H⁺(aq) + Cl⁻(aq).

An Arrhenius base is a substance that dissociates in water to form hydroxide ions (OH⁻<span>). 
In this example lithium hydroxide is an Arrhenius base:</span>

LiOH(aq) → Li⁺(aq) + OH⁻(aq).

What is happening to the protons in the nucleus and the number of orbits as you move across the periodic table from left to righ
baherus [9]

Explanation:

As you move across the periodic table, the number of protons and neutrons increases but the number of orbital levels of the period remains the same. The atomic radii therefore decrease, across the period, because the increase in proton number causes an increased pull of the orbital electrons bringing them closer to the nucleus.

As you move down a group in a periodic table, the number of orbital levels increase.  The effective nuclear charge of the nucleus of the atoms decreases due to the increased number of orbital levels that shield the valence electrons from the attractive force nucleus.

How many moles are in 63 g of NH4 (molar mass= 18g)?
sdas [7]

To answer this question, all you to do is to divide the mass by the molar mass and that should get you your moles.

=63g\ NH_{4}\ x\ \frac{1\ mol\ NH_{4}}{18g\ NH_{4}}

<em>= 3.5 mol NH₄</em>

Hydrazine is a great chemical propellant because it creates a lot of gaseous products that need to expand and escape from their
Burka [1]

We have to look for safe and non - hazardous characterstics when trying to find new propellants.

<h3>What are propellants ?</h3>

Propellants are any gas, liquid, or solid the expansion of which can be used to impart motion to another substance or object.

The Desirable properties for propellant combinations are ;

  • low molecular mass and high temperature of reaction products (for high exhaust velocity),
  • high density (to minimize tank weight),
  • low hazard factor (e.g., corrosivity and toxicity),
  • low environmental impact,
  • low cost.
