Answer:
protons
Explanation:
An element, by definition, always has the same number of protons. Sodium, element 11, has 11 protons. Anything with 11 protons is a sodium atom, regardless of the number of neutrons, electrons, or politicians.
Answer:
<h2>251 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 0.251 × 1000
We have the final answer as
<h3>251 g</h3>
Hope this helps you
4 x 
in dL will be 4 x 
<h3>Conversion from dL to cm^3</h3>
Recall that:
Deci =
Centi = 
Thus, 1 dl = 100 ml
This means that converting from dl to requires multiplying by 
.
Applying this principle, 4 x in dL to will be:
4 x x = 4 x
Therefore, 4 x dl will be 4 x

The answer would be 0.8 mol of x left over....
AND THATS IS WHY...refer to the pic below...

Answer:
As explained
Explanation:
My reaction will be positive and I will feel elated that a new elements has been discovered as this will be a modification of the earlier claim by berzelius and the likes that there are over 106 known elements ; Metal, Non Metals and Metalloids.
However, fitting the new discovered element in between Tin and antimony may be an issue, as the physical properties of the new elements has to be known, its melting point, metals or non metals as this is paramount to be able to classify the elements. if the elements fits in between tin and antimony, it is an indication that the elements is mot likely a metal or non-mental and may belong to group IVB or VB. Another issue is, the discoverer will have to create his own periodic table to be able to stand in with the discovery of Dimitriy Mendelev.
