Answer:
Proton and neutrons
Explanation:
they both have a mass of 1 amu or 1 atomic mass
1) convert Celsius to Kelvin
24 + 273 = 297
2) convert kPa to atm
62.2 / 101.3 = 0.614
3) plug numbers into the ideal gas law formula
Answer: 0.088 mols
When a metal reacts with a salt, it displaces the metal present in the salt only if the metal has higher relative reactivity.
in this case , the displacing metal is same as the metal present in salt. both (being same metal)have same relative reactivity. hence, no displacement . NO reaction.
4. It is an endothermic process. The body of someone taking a shower would be absorbing heat from the environment, another example of this would be cooking an egg
5. Ice melting is endothermic. The ice is absorbing heat from the environment, water freezing would be an exothermic reaction as it is transferring heat into the environment
6 however i do not have an answer for. I may just be a little dense but I'm not entirely sure what it is asking when it asks what the system is.
When an iron object is left in damp air for a considerable time, it gets covered with a reddish- brown flaky substance called rust. ... Rusting of iron is a chemical change because a new substance iron oxide is formed. The presence of oxygen and water or water vapour is essential for rusting.
