A piece of copper alloy with a mass of 85.0 g is heated from 30. °C to 45 °C. In the process, it absorbs 523 J of energy as heat
Ne4ueva [31]

Answer:

410.196 J/[kg*°C].

Explanation:

1) the equation of the energy is: E=c*m*(t₂-t₁), where E - energy (523 J), c - unknown specific heat of copper, m - mass of this copper [kg], t₂ - the final temperature, t₁ - initial temerature;

2) the specific heat of copper is:

c=\frac{E}{m*(t_2-t_1)}; \ => \ c=\frac{523}{0.085*(45-30)}=\frac{523}{1.275}=410.196[\frac{J}{kg*C}].

How many moles of water are formed when 22 mol of methane combusts?
icang [17]
Methane is a hydrocarbon which when burns in air (combustion) produces carbon dioxide and water. The equation for the reaction;
CH4 +2O2 = CO2 +2H2O
When one mole of methane combusts 2 moles of water are formed
Therefore; when 22 moles of methane combusts 44 moles of water are formed (22 ×2)

Which of dalton's postulates about atoms are inconsistent with later observations? do these inconsistencies mean that dalton was
Neporo4naja [7]

1)  Dalton stated that atom is matter that can not be divided, but it is proved that the atom can be divided into subatomic particles  (electrons, protons and neutrons).

2) He stated that atoms of one element can not be changed into atoms of other  elements, but now that is possible by nuclear reactions.

Today we still use his postulate: Atoms combine in the ratio of small whole numbers to form stable compounds, for example H₂O.
