The concentration of an acid IS A MEASURE OF THE QUANTITY OF ACID DISSOLVED IN WATER THAT IS DESIGNATED BY MOLARITY.

Acids are always aqueous solutions, that is they are always dissolved in water. The concentration of an acid refers to the quantity of hydrogen ions that are present in the acid. If an acid contain a large quantity of hydrogen ion, it will be described as concentrated acid and if it contains a little quantity of hydrogen ion it will be described as diluted acid. The quantity of hydrogen ion [pH] in acids ranges from 1 to 6; 1 is very acid acidic and 6 is the least acidic.

What is the fraction of the hydrogen atom's mass (11h) that is in the nucleus? the mass of proton is 1.007276 u, and the mass of

ololo11 [35]

Hello there!

To determine the fraction of the hydrogen atom's mass that is in the nucleus, we have to keep in mind that a Hydrogen atom has 1 proton and 1 electron. Protons are in the nucleus while electrons are in electron shells surrounding the nucleus. The mass of the nucleus will be equal to the mass of 1 proton and we can express the fraction as follows:

$Mass Fraction= \frac{mass 1 Proton}{mass H atom} = \frac{1,007276 u}{1,007825}=0,9995$

So, the fraction of the hydrogen atom's mass that is in the nucleus is 0,9995. That means that almost all the mass of this atom is at the nucleus.

Have a nice day!

What is the change in energy of a gas at a pressure of 105 kPa, if 245 J of energy is added causing a change in volume from 25.3

Ahat [919]

Answer:

-1151.5 J

Explanation:

Given that:

The supplies energy = 245 L

The energy used in the expansion of gas = Pressure ×ΔV (change in volume)

At standard conditions;

Pressure = 105 × 10³ Pa

energy used in the expansion = 105 × 10³ Pa × (38.6 - 25.3)L

= 1396.5 J

Thus, the change in the energy of gas = 245 - 1396.5 J

= -1151.5 J

Hence, we can conclude that the gas has lost its own energy in the process of expansion.

How many moles of water are produced from 13.35 mol of oxygen?

drek231 [11]

2 H2 + O2 = 2 H2O

1 mole O2 --------------- 2 moles H2O
13.35 moles O2 -------- ( moles H2O)

moles H2O = 13.35 x 2 / 1

= 26.7 moles of H2O

hope this helps!
