So yield = actual/predicted*100
You need to find the theoretical yield. CONVERT INTO MOLES. this is the 1st step you do in most calculation questions.
I got 15.92%
M = 4.79 kg = 4790 g
d = 7.86 g/cm3
density = mass/volume
v = m/d
v = 4790/7.86
v = 609.4 cm3
1 cm3 = 10^-2 dL
v = 609.4 x 0.01 = 6.09 dL
Answer:
1.Write the balanced chemical equation.
2.Convert the units of the given substance (A) to moles.
3.Use the mole ratio to calculate the moles of wanted substance (B).
4.Convert moles of the wanted substance to the desired units.
Explanation:
D. Being cold temperatures can result in a cold nose. With prolonged exposure The body will start to lose heat faster than it can generate it, this is the result of hypothermia.
Explanation:
Knowing the number of valence electrons in one of the alien elements helps in identifying it because the number of valence electrons can help categorize the alien element. Similar elements have the same valence electrons and knowing the category of the element can help further analyze the element.
