Isotopes have different <u>mass number</u> but same atomic number

mash [69]3 years ago

Answer:

Neutrons

Explanation:

Isotopes are atoms with same protons and different neutron number.  For eg: Hydrogen has 0 neutrons. But a stable isotope of hydrogen called Deuterium has 1 neutron but both still have 1 proton which makes them isotopes.

What does Gibbs free energy predict?
kicyunya [14]

Answer:

It predicts whether or not a reaction will be spontaneous.

Explanation:

The equation;

∆G= ∆H - T∆S enables us to obtain the Gibbs free energy of a chemical process.

The Gibbs free energy value tells us whether a chemical process will be spontaneous or not.

When;

∆G>0 the reaction is not spontaneous

∆G=0 the reaction is at equilibrium

∆G<0 the reaction is spontaneous

kodGreya [7K]
Dalton's Law of Partial Pressures, commonly applied to ideal gases, explains that the partial pressures of individual, non-reacting gases are equal to the total pressure exerted by the gas mixture. The given gas mixture composed of 90% argon and 10% carbon dioxide has the following partial pressures: 3.6 atm for argon and 0.4 atm for carbon dioxide (answer).

A 20g sample of iron at a temperature of 120oC is placed into a container of water. There are 300 milliliters of water in the co
galben [10]

Answer:

30.63 °C will be the final temperature of the water.

Explanation:

Heat lost by iron will be equal to heat gained by the water

-Q_1=Q_2

Mass of iron = m_1=20 g

Specific heat capacity of iron = c_1=0.444 J/g^oC

Initial temperature of the iron = T_1=120^oC

Final temperature = T_2=T

Q_1=m_1c_1\times (T-T_1)

Volume of water = 300 ml

Density of water = 1 g/mL

Mass of water= m_2=300 mL\times 1 g/mL = 300 g

Specific heat capacity of water= c_2=4.184 J/g^oC

Initial temperature of the water = T_3=30^oC

Final temperature of water = T_2=T

Q_2=m_2c_2\times (T-T_3)

-Q_1=Q_2

-(m_1c_1\times (T-T_1))=m_2c_2\times (T-T_3)

On substituting all values:

we get, T =  30.63°C

30.63 °C will be the final temperature of the water.
