<h3>Answer:</h3>

Different mass, same atomic number

<h3>Explanation:</h3>
  • Elements are made of similar atoms, however the atoms may have different number of neutrons but the same number of protons in their nucleus.
  • Such atoms that have equal number of protons but different number of neutrons are known as isotopes.
  • Difference in the number of neutrons makes isotopes to have different mass numbers.
  • Atomic number is the number of protons in the nucleus of an atom, therefore, isotopes have the same atomic number.

How many moles of water are produced if 5.43 mol PbO2 are consumed
Mariana [72]
It has to be understood that 2 moles of oxygen are there in each mole of PbO2. Then it has to be calculated for 2 moles of oxygen.

Amount of oxygen = 2 * 5.43 moles
                              = 10.86 moles
Now it is also a fact that each mole of H2O contains 1 mole of oxygen. Then it can be easily concluded that 10.86 moles of water will be produced. I hope the procedure is clear enough for you to understand.

You have a 15.0 gram sample of gold at 20.0°C. How much heat does it take to raise the temperature to 100.0°C?
Nadusha1986 [10]

Answer:

=154.8 J

Explanation:

The rise in temperature is contributed by the change in temperature.

Change in enthalpy = MC∅,  where M is the mass of the substance, C is the specific heat capacity and ∅ is the change in temperature.

Change in temperature = 100.0°C-20.0°C=80°C

ΔH=MC∅

The specific heat capacity of gold= 0.129 J/g°C

ΔH= 15.0g×0.129J/g°C×80°C

=154.8 J
