Phosphoric acid is a weak acid, while rubidium hydroxide is a strong acid.
H₃PO₄ + RbOH --> Rb₃PO₄ + H₂O
We get Rb₃PO₄ because PO₄ has a charge of 3-, that is PO₄³⁻. Rb has a charge of 1+. You give the subscript of one the charge of the other as this is an ionic compound. So you end up with Rb₃PO₄, a neutral compound.
Now let's balance the equation:
H₃PO₄ + 3RbOH --> Rb₃PO₄ + 3H₂O
Answer:
The answer is
<h2>184.54 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density of iron = 7.92 g/mL
volume = final volume of water - initial volume of water
volume = 49.10 - 25.80
Volume = 23.3 mL
It's mass is
mass = 7.92 × 23.3 = 184.536
We have the final answer as
<h3>184.54 g</h3>
Hope this helps you
Answer:
the answer is 0.45 kilograms.
Rigor mortis is the stiffening of the body after death. After death, the body begins to get cold. From about two to six hours after death, the muscles start to stiffen, probably because the actin and myosin filaments of the muscle slide into each other. The rigor mortis starts at the eyelids, jaw and neck and then slowly spreads to all parts of the body within six hours.
Contrary to popular belief, rigor mortis will occur more quickly in high ambient temperatures than in cold conditions. This is because the underlying chemical reaction occurs faster at higher temperatures.
