Answer:
3,density
Explanation:
because it doesn't measure dirrectly
The balanced chemical equation would be as follows:
<span>
Mg + O2 → MgO2
</span>We are given the amounts of the reactants. We need to determine first which one is the limiting reactant. We do as follows:
62.0 g Mg (1 mol / <span>24.31 g ) = 2.55 mol Mg
</span>55.5 g O2 ( 1 mol / 32 g ) = 1.74 mol O2 -----> <span>consumed completely and therefore the limiting reactant
2.55 mol - 1.74 mol O2( 1 mol Mg / 1 mol O2 ) = 0.81 mol Mg excess</span>
Answer:
a variable (often denoted by x ) whose variation does not depend on that of another.
Explanation:
Answer:
Explanation:
The second best answer is likely well water. But it is possible that well water can be contaminated as well with soluble minerals.
See water would have salt in it which would make it hard to use.
River water could be containing dirt which would make washing hard to do.
Rain water is likely the best water to use.
One oxygen molecule is made of O2
