Answer:
a strong electrolyte
Explanation:
Let's look at the meaning of the following terms so we can obtain the right answer by means of elimination.
- Strong Electrolyte : A strong electrolyte is a solution/solute that completely, or almost completely, ionizes or dissociates in a solution. These ions are good conductors of electric current in the solution.
- Weak Electrolyte : A weak electrolyte is an electrolyte that does not completely dissociate in aqueous solution. The solution will contain both ions and molecules of the electrolyte. Weak electrolytes only partially ionize in water (usually 1% to 10%)
- Strong ion : Strong ions are cations and anions that exist as charged particles dissociated from their partner ions at physiologic pH. Thus, these ions are “strong” because their ionization state is independent of pH.
Strong Electrolye fits the condition and hence is the correct option.
Answer:
7.5 % of Ag
Explanation:
Total mass of sterling silver chain is:
Mass of silver + Mass of copper
33.3 g Ag + 2.70g of Cu = 36 g
% of Silver is (mass of silver / total mass) . 100 →
(2.70 g / 36 g) . 100 → 7.5%

<span>The answer is true that Group 1A elements (except for hydrogen) are the
alkali metals. Groups 2A are alkaline earth metals. Group 3B-12B are transition
metals. Group 3A to 4A except Boron, Carbon, Nitrogen, oxygen, silicon,
phosphorus, sulfur, germanium, astatine, selenium, antimony, tellurium, polonium
are basic metal. Carbon, nitrogen, oxygen, phosphorus, sulfur and selenium are
nonmetals. Boron, silicon, germanium, astatine, antimony, tellurium and polonium
are metalloids. Groups 7A are halogens. Groups 8A are noble gases. The lower
part of the periodic table are lanthanides and actinides.</span>
Answer: 6.0 g of silicon has more atoms
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 
of particles.
To calculate the moles, we use the equation:
a) 
1 mole of Si contains = atoms
0.21 moles of Si contains = 
atoms
b) 
1 mole of Fe contains = atoms
0.11 moles of Fe contains = 
atoms
Thus 6.0 g of silicon has more atoms
