Answer:
a.labeling food with an ingredient list to inform consumers
Explanation:
Explanation:
Given that,
Mass number, A = 302
Atomic number, Z = 119
We know that, atomic number = no of protons
Protons = 119
Mass no. = No. of neutrons + No. of protons
302 = No. of neutrons + 119
No. of neutrons = 302 - 119
= 183
No. of electrons = No. of protons
= 119
The mass would be same because of the law of conservation which states that the mass of the reactants must equal to the mass of products
Answer:
Zinc
The element was probably named by the alchemist Paracelsus after the German word Zinke (prong, tooth).
Explanation:
Answer: D) 
g
Explanation: The question asks to convert formula unit to grams. It is a unit conversion problem.
1 mole equals to Avogadro number of formula units. So, to convert the given number of formula units to moles, we need to divide by the Avogadro number. After this, we do moles to grams conversion and for this the moles are multiplied by the molar mass of the compound. Molar mass of AgCl is 143.32 gram per mol.
= g
So, the correct option is D) g
