Answer:
Relative atomic mass and it is expressed in atomic mass unit (amu)
Explanation:
AMU:
Atomic mass unit is define as the 1/12 the mass of an atom of carbon-12.
C12 has six neutron and six protons in the nucleus.
This unit is used to express the masses of atoms. We know that masses of atoms are very small and we do not have any such type of balance that can measure very small quantity. So that is way we use this scale to measure small quantity. For example, according to this scale
relative atomic mass of hydrogen is 1.008 amu
relative atomic mass of oxygen is 15.999 amu
relative atomic mass of uranium is 238.0289 amu
relative atomic mass of chlorine is 35.453 amu
Answer:
B, liquid to solid.
Explanation: Since heat is being released, the particles for H2O would clump up. Heat is basically being taken out.
Answer: 1 part is sulfuric acid is a catalyst
2 part is vanadium (V) oxide is a catalyst
Explanation:
Nitrogen gas consists of a diatomic nitrogen atom. So, the correct answer is B.
The answer to this question would be: <span> 10 °K
Kelvin and Celcius scales are different by 273</span> degrees but their ratio is the same. One degree in Kelvin is equal to one degree in Celcius. That mean, 10 °C change in Celcius would be same as <span> 10 °K changes in Kelvin too. </span>
