True I believe since every person has a different temperature and sound waves.
Pretty sure its asteroids but double check to make sure.... hope this helps!
Answer:
The answer to your question is pH = 1.45
Explanation:
Data
pH = ?
Volume 1 = 200 ml
[HCl] 1 = 0.025 M
Volume 2 = 150 ml
[HCl] 2 = 0.050 M
Process
1.- Calculate the number of moles of each solution
Solution 1
Molarity = moles / volume
-Solve for moles
moles = 0.025 x 0.2
result
moles = 0.005
Solution 2
moles = 0.050 x 0.15
-result
moles = 0.0075
2.- Sum up the number of moles
Total moles = 0.005 + 0.0075
= 0.0125
3.- Sum up the volume
total volume = 200 + 150
350 ml or 0.35 l
4.- Calculate the final concentration
Molarity = 0.0125 / 0.35
= 0.0357
5.- Calculate the pH
pH = -log [H⁺]
-Substitution
pH = -log[0.0357]
-Result
pH = 1.45
Answer:
It can’t displace any more than its volume, assuming there is no external force pushing downwards.
The type of energies or the words in this item
are matched with the given descriptions. The lists below are as follow.<span>
<span>a. The word that best match this description is MECHANICAL
energy. In most sources, mechanical energy is described to be that
energy that is possessed by an object with respect to its motion and position. </span>
<span>b. The answer to this item is LIGHT energy. This type
of energy can be created through different means (i.e. radiation, chemical, and
mechanical). This is the energy emitted by hot objects such as the sun, lasers,
and bulbs.</span>
<span>c. The type of energy that is transferred by the movement of
the electrons through a conductor is ELECTRICAL energy. The movement of
the electrons along the line is commonly called as the current. Moreover, this
is also a type of kinetic energy because of the movement of the electrons.
Thus, the faster the movement of the electron the higher is the energy. </span>
<span>d. The type of energy that is stored in batteries or food is
CHEMICAL energy. This type of energy is that which is stored in the
bonds of the different chemical compounds. This is also most commonly released
when reaction between elements/compounds happen.</span>
<span>e. The energy that travels through vibrations and waves is
SOUND energy. As given above, this is associated with the movement or
vibrations of the matter. This is also a type of mechanical energy because of
the waves produced through to the vibrations.</span>
<span>f. The type of energy that is found in the nucleus and atoms
is the NUCLEAR energy. Nuclear
reactions most often released this type of energy simultaneous with the
generation of heat. </span>
<span>g. The stored energy is called the POTENTIAL energy. The
equation for this energy is mgh where h is the height, pertaining to the
position of the object. Once the object is released, it will be converted to
other forms of energy. </span>
<span>h. The answer to this item is THERMAL energy. This type of
energy can be transferred in three different ways: (1) conduction, (2)
convection, and (3) radiation.</span></span>
