Answer:
1.56 g of water was involved in the reaction
Explanation:
From the stoichiometric equation
2Na + 2H2O = 2NaOH + H2
NB : Mm Na= 23, Mm H2O = ( 2+16)= 18
2(23) of Na requires 2(18) of water
Hence 1.99g of Na will require 1.99×2×18/2(23) of water = 1.56 g of water
The most accurate way to measure a dry ingredient like flour, sugar or chocolate chips is in terms of its weight, which is measured in regular ounces.
The answer is chloroplast
It's a surface current because it's driven by the winds near the equator.
Explanation:
The Gulf stream<span> System is </span>one of<span> the world's most intensely studied current systems. The </span>Gulf stream<span> begins upstream of </span>the promontory<span>, </span>wherever<span> the </span>Sunshine State<span> Current ceases to follow the </span>seabed<span>. The position of the Stream </span>because it<span> leaves the coast changes throughout the year. </span>within the<span> fall, it shifts north, </span>whereas within the<span> winter and early spring it shifts south.</span>
Two moles of SO2 means 1.204x10^24 molecules, since there are 3 atoms in one molecule, multiply 1.204 x10^24 by 3 and you get 3.612x10^24.
