Answer:
Atomic radius of Strontium is 27.38pm
Explanation:
In a face-centered cubic structure, the edge, a, could be obtained using pythagoras theorem knowing the hypotenuse of the unit cell, b, is equal to 4r:
a² + a² = b² = (4r)²
2a² = 16r²
a = √8 r
As edge length of Strontium is 77.43pm:
77.43pm / √8 = r
27.38pm = r
<h3>Atomic radius of Strontium is 27.38pm</h3>
Answer: If you run the suspension through a filter such as a filter paper or a sintered glass funnel, the solid particles will remain on the filter while the liquid passes through the filter, thus separating the two. ... Filtration is the act of separating a heterogeneous mixture of a solid and a liquid.
Explanation: hope this works
Answer:
A- observation
B- hypothesis
C,D,E- experiment
F- conclusion
Explanation:
Lucia has just carried out the scientific process. An observation refers to paying close attention to a particular phenomenon in nature. This leads to the proposition of an intelligent guess about the observed phenomenon. This intelligent guess is called a hypothesis.
The hypothesis now guides the design of an experiment designed to confirm or disprove the hypothesis. The results of the experiment now leads to the formulation of a conclusion as Lucia has just done.
Answer:
11.6 grams of MgO can be produced with 4.63 grams of oxygen.
Explanation:
Mass of oxygen gas = 4.63 g
Moles of oxygen gas =
According to reaction, 1 mole of oxygen gas gives 2 moles of magnesium oxide, then 0.1447 moles of oxygen gas will giv e:
of magnesium oxide
Mass of 0.2894 moles of magnesium oxide:
= 0.29 mol × 40 g/mol = 11.6 g
11.6 grams of MgO can be produced with 4.63 grams of oxygen.
