Ionic bonds is formed between a metal and a nonmetal because the metal transfers it's valence electrons to the nonmetal. Electrons doesn't transfer between two nonmetal because both are negatively charged.
There are several process in the nature, which keeps water cycling between them. By Precipitation, Earth's sphere gets water which we use in several ways, and by evaporation & sublimation, it goes back to upper spheres of the Earth's atmosphere and cycle happens again & again.
Hope this helps!
Answer:
Process manufacturing.
Explanation:
Process manufacturing, a class of manufacturing which is associated with the formulas and the manufacturing of recipes. This type of manufacturing is different from discrete manufacturing as it deals with discrete units and assembly of the components.
<u>
This type of manufacturing is common in food, chemical, beverage, nutraceutical, pharmaceutical, cannabis, and mostly biotechnology industries. In this manufacturing, the relevant factors are the ingredients and the bulk materials rather than the individual units. </u>
<u>Thus, formation of ice is an example of process manufacturing in which different ingredients are added and using recipe of freezing.</u>
Answer:
The amount of sodium in this sample = 32.4 grams
Explanation:
Mass of Sodium = 23 g/mol
Mass of Chlorine = 35.5 g/mol
Mass of NaCl = 35.5 g/mol
Fraction of Na in NaCl = 
=0.648
We are given a sample of 50 grams of sodium chloride.
The amount of sodium in this sample = 
The amount of sodium in this sample = 
The amount of sodium in this sample = 32.4 grams
Answer:
Actual yield = 86.5g
Explanation:
Percent yield = 82.38%
Theoretical yield = 105g
Actual yield = x
Equation of reaction,
CaCO₃ + HCl → CaCl₂ + CO₂ + H₂O
Percentage yield = (actual yield / theoretical yield) * 100
82.38% = actual yield / theoretical yield
82.38 / 100 = x / 105
Cross multiply and make x the subject of formula
X = (105 * 82.38) / 100
X = 86.499g
X = 86.5g
Actual yield of CaCl₂ is 86.5g
