A.) true
Because the rocks are formed near lava so the texture would be smooth
Answer:
0.0634 M HCl
Explanation:
Since HCl and NaOH react in a one-to-one mole ratio, we can just use M1V1 = M2V2 to solve for M1 (the concentration of HCl)
M1 = ? M HCl
V1 = 24.30 mL HCl
M2 = 0.120 M NaOH
V2 = 12.84 mL NaOH
M1(24.30 mL HCl) = (0.120 M NaOH)(12.84 mL NaOH)
M1 = 0.0634 M HCl
The answer is, 699g
The idea here is that you need to use the mole ratio<span> tha exists between </span>ferric oxide<span>, </span><span><span>Fe2</span><span>O3</span></span><span>, and iron metal, </span>Fe<span>, to determine how many moles of the latter will be produced when </span>all the given mass<span> of the ferric oxide reacts...

Answer: M = 0.01 M C12H22O16
Explanation: First convert the mass of C12H22O16 into moles using the molar mass of the compound.
5 g C12H22O16 x 1 mole C12H22O16 / 342 g C12H22O16
= 0.01 mole C12H22O16
To calculate the molarity we will use the following formula.
M = n / L
= 0.01 mole / 1 L
= 0.01 M C12H22O16
