The balanced equation for the reaction is
HCl + NaOH = H2O + NaCl
So for every mole of NaOH used, one mole of HCl is neutralized. So let's determine how many moles of NaOH we used. That will simply be the volume (in liters) of solution multiplied by the molarity. So
0.0493 L * 0.151 mol/L = 0.0074443 mol
Because of that 1:1 ratio, we now know that 0.0074443 moles of HCl was in the sample. Since molarity is moles per liter, a little division will give us the molarity of the HCl solution. So
0.0074443 mol / 0.025 L = 0.297772 mol/M = 0.297772 M
Rounding to 3 significant figures gives 0.298 M.</span>
The answer is D all of the above because I just got done with this question
Answer:
the strongest is fluoroantimonic acid and the weakest is hydrocyanic acid
The grand canyon is 884 m deep
<h3>Formula for velocity of echo</h3>
The velocity of an echo can be obtained by using the following formula
v = 2x / t
Where
- v is the velocity
- x is the distance
- t is the time
With the above formula, we can determine how depth the grand canyon. Details below:
<h3>How to determine the depth of the grand canyaon</h3>
- Velocity (v) = 340 m/s
- Time (t) = 5.2 s
- Depth (x) =?
v = 2x / t
340 = 2x / 5.2
Cross multiply
2x = 340 × 5.2
2x = 1768
Divide both sides by 2
x = 1768 / 2
x = 884 m
Thus, the grand canyon is 884 m deep

Answer:
Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area.
