Answer:
brittle is not a characteristic of metals
Answer:
Fluorine-21 has a half-life of approximately 5 seconds. How much of a 200 gram sample would remain after 1 minute.
1/4096
We have that the original pressure of this gas is mathematically given as
P2=17.854 kPa
<h3>
Boyle's law</h3>
Question Parameters:
AT constant temperature, a gas is compressed from 5.5 L to 1 L.
At 1 L, the pressure of the gas is 98.2 kPa
Generally the equation for Boyle's law is mathematically given as
P1V1=P2V2
Therefore
P2=17.854 kPa

Answer:
The relative number of products and reactants
Explanation:
- The numerical coefficients in chemical equations show the ratio of the molecules of each substance involved in a chemical reaction that is both reactants and products.
- The coefficients in a balanced chemical equation indicate the relative number of moles of reactants and products.
- Additionally, coefficients are important to prove the law of conservation of mass.
