Food contamination is classified into three types: 1) Physical 2) Chemical Biological.
Physical contamination occurs if a paint chip falls into soup
It must be noted that, physical<span> contamination get into food through</span><span> poor procedural practices such as</span><span> dirt, hair, nail polish flakes, broken glass, nails, staples, plastic fragments, bones, bits of packaging, etc.</span>
We know that Zinc (Zn) has a molar mass of 65.39
g/mol. Hence the remaining is:
136.28 - 65.39=70.89
While molar mass of Chlorine (Cl) is 35.453 g/mol .
70.89 / 35.453 =2 => Cl
<span>So the formula is ZnCl2</span>
Humans.
Humans have mass and take up space. :)

Answer:
1. The physical states of the reactants and products.
2. The concentration of the reactants and products.
3. The conditions such as temperature, pressure or catalyst etc which affect the reaction.
4. The heat changes accompanying the reaction i.e. whether heat is evolved or absorbed during the reaction.

Answer:
25.157 cm³
Explanation:
Data Given:
Mass of Sugar (m) = 40g
Density of sugar given in literature = 1.59 g/cm³
Volume of Sugar = ?
The formula will be used is
d = m/v ........................................... (1)
where
D is density
m is the mass
v is the volume
So
Rearrange the Equation (1)
d x v = m
v = m/ d ................................................ (2)
put the given values in Equation (2)
v = 40g / 1.59 g/cm³
v = 25.157 cm³
volume of 40 g of sugar = 25.157 cm³
