The mass of the sample of the material is 0.1664 g.
<h3 /><h3>What is specific heat?</h3>
The amount of energy needed to raise the temperature of one gram of a substance by one degree Celsius.
By the formula of specific heat
Given, that the specific heat (c) of material is 0.416 J/gC
The difference in temperatures is 30°C to 50°C
The mass=?
Q = heat, 50 J
Putting the values in the equation
Thus, the mass of the samples is 0.166 g.

If the food is in smaller chunks its easier for your stomach acids to break down then bigger pieces of food.
Answer:
Three halogens:
Fluorine, chlorine, bromine.
Explanation:
Halogens are present in group seventeen of periodic table.
Their are five elements in this group fluorine, chlorine, bromine, iodine, astatine.
Three halogens:
Fluorine, chlorine, bromine.
All these share common properties such as,
All of these have seven valance electrons.
When combine with hydrogen they form acids.
H₂ + Cl₂ → 2HCl
All of these are toxic in nature.
They are highly electronegative and most reactive elements.
When combine with metals they form salts such as sodium chloride, magnesium bromide.
2Na + Cl₂ → 2NaCl
2Na + Br₂ → 2NaBr
Mg + Br₂ → MgBr₂
Mg + Cl₂ → MgCl₂
