Answer:
The mass
Explanation:
the mass grams of 3.75 × 10 21 atoms of Li is
40. 21 atom of Li
Answer:
25.0g is the mass of sulfur
Explanation:
The sulfur and the oxygen are 50:50. That means there is 1 mole of S per mole of O.
To solve this question we need to convert the mass of O to moles, as moles of O = Moles of S, we can find the moles of S and its mass:
<em>Moles O = Moles S:</em>
12.5g O * (1mol / 16g) = 0.781 moles
<em>Mass S:</em>
0.781 moles * (32g / mol) =
<h3>25.0g is the mass of sulfur</h3>
How does the law of conservation of mass apply to this reaction: C2H4 + O2 → H2O + CO2?
Answer:
<h3>The answer is 3754.33 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 21.7 kg = 21700 g
volume = 5.78 cm³
We have
We have the final answer as
<h3>3754.33 g/cm³</h3>

Answer: -
B: it can be flattened and bent
Explanation: -
Metals are malleable and can be flattened. Metals are ductile and can be deformed and bent.
Metals are bonded together by metallic bonds.
Hence a substance that is composed of atoms that are held together by metallic bonds can be flattened and bent.
