It will melt
This is because the molecules in the metal begin to move faster and faster turning from solid to liquid
Answer:
Venus has a very small axial tilt -- 3 degrees versus Earth's 23.5 degrees. Its dense, acidic atmosphere produces a runaway greenhouse effect that keeps the surface at around 865 degrees F year-round, which is hot enough to melt lead.When the solar system settled into its current layout about 4.5 billion years ago, Venus formed when gravity pulled swirling gas and dust together to form the second planet from the Sun. Like its fellow terrestrial planets, Venus has a central core, a rocky mantle and a solid crust.

He would hv concluded that the ratio of the masses of nitrogen to sulphur is in the ratio 1 :3
Answer:
.54 mol
Explanation:
Using the ΔH given for the balanced reaction, convert kilojoules to moles of CO2 using the stoichiometric ratio:
250 kJ×(6 moles CO22803 kJ)=0.5351 moles CO2
The answer should have two significant figures, so round to 0.54 moles CO2.
Notice that coefficients in stoichiometric equations (indicating numbers of moles) are exact, so they do not constrain the number of significant figures.
(NH4)2CO3(aq)+ZnCl2 (aq)-----> ZnCO3(s)+2NH4Cl(aq)
Zn²⁺ +CO3²⁻-----> ZnCO3
