Answer:

Well 4 in H2SO4 would be called Sulfuric Acid

Explanation:

The Reason why its called by its name because the form lua is called this its because its a colorless Acid that burns it also has dissolving metals and other stuff inside of it. it has another name called oil of vitriol. hopefully this helps ^^!

Gastric acid pH can range from 1 to 4, and most of the acid is HCl.
erma4kov [3.2K]

Given the molarity of the solution is3.03*10^{-2}.

The volume of the solution is 10.9/1000 L

Number of moles of HCl = Molarity * volume of the solution in L

Number of moles of HCl =3.03*10^{-2}*\frac{1000}{10.9}

Number of moles of HCl = 2.7 moles.

Therefore number of moles of HCl in 10.9 ml of the stomach acid is 2.7 moles

A standard gold bar has a mass of 12.4 kg. When the gold bar is placed into a container of water the volume changes by 642 mL. W
AlekseyPX

Answer:

19.3 g/mL

Explanation:

The following data were obtained from the question:

Mass (m) = 12.4 kg

Volume (V) = 642 mL.

Density (D) =.?

Next, we shall convert 12.4 kg to grams. This can be obtained as follow:

1 kg = 1000 g

Therefore,

12.4 kg = 12.4 × 1000

12.4 kg = 12400 g

Therefore, 12.4 kg is equivalent to 12400 g.

Finally, we shall determine the density of the gold as follow:

Density is simply defined as the mass of the substance per unit volume of the substance. It can be represented mathematically as:

Density (D) = mass (m) / volume (V)

D = m/V

With the above formula, the density of gold can easily be obtained as follow:

Mass (m) = 12400 g

Volume (V) = 642 mL.

Density (D) =.?

D = m/V

D = 12400/642

D = 19.3 g/mL

Therefore, the density of hold is 19.3 g/mL

VLD [36.1K]
<h2>The required "option is b) potential energy".</h2>

Explanation:

  • The energy which is associated with the motion of the object is called kinetic energy.
  • The energy which is associated with the amount of heat released is known as thermal energy.
  • The energy which is released during a chemical reaction is known as chemical energy.

          Therefore, option (a), (c), and (d) are incorrect.

  • The energy which is possessed by a stationary object or associated with the position of an object is called as potential energy.
  • Hence, the correct option is potential energy.
