Answer:
Knowing that boron has an atomic mass of 10,811 means that all boron isotopes on average weigh 10,811 u.
Explanation:
The atomic mass of an atom is the mass of the atom measured in u (unified atomic mass unit), although we can also express it as Da (Dalton's unit)
Atomic mass refers to the average mass that all isotopes of that element have.
When we speak of isotopes we are referring to the element itself but with a different number of neutrons, which makes it modify its mass number.
Answer:
<h3>The answer is 2 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 48 g
volume = 24 cm³
We have
We have the final answer as
<h3>2 g/cm³</h3>
Hope this helps you
It’s is a!!!!! Also can I Have Brainlyest please :)
Answer:
Reactants are transformed into products
Explanation:
Chemical reactions are happening everywhere, it may be represented by the following equation:
A(aq) + B(s) ⇒ C(g) + D(l)
The left side represent the reactants that interact to get the products.
In the parenthetycal note is the state of the compound, in this case, aquose solution (aq), solid (s), gas (g), liquid (l)
7. Neutralisation. Which would (obviously) appear GREEN on the chart.
