Molarity
a. Na2CO3
Molar mass = 106 g/mol
n= 109 g / (106 g/mol) = 1.028 mol
b. 6.00L
c. M=n/V
M = 1.028 mol / 6.00 L
M= 0.1713 mol / L
Answer: The molarity of the sodium carbonate solution is 0.1713 mol/L
H2O I THINK THATS THE ANSWER IT SHOULD FORM WATER IF THATS WHAT YOUR ASKING ? 2 HYDROGENS 1 OXYGEN .
Answer:
As per the general rule for finding oxidation number, When H is bonded with non-metal it has oxidation number as 1. As in the given ion, hydrogen is bonded with non-metal oxygen and there are three hydrogen atom, the oxidation number of hydrogen atom is 3.
The answer is:
Sedimentary rock, metamorphic rock, and igneous rock.
<u>If you'd like to know why:</u>
Any type of rock can be a metamorphic rock. Metamorphic rocks are formed when a rock (any kind of rock) undergoes immense heat and pressure. If melting does not occur, it will become a metamorphic rock. If it melts, it becomes magma and from there, the magma, could eventually become an igneous rock and the rock cycle will start again.
