0.1 mol/L
. The concentration of the HCl is 0.1 mol/L
a) Write the <em>balanced chemical equation
</em>
HCl + NaOH → NaCl + H2O
b) Calculate the <em>moles of NaOH
</em>
Moles of NaOH = 0.050 L NaOH x (0.1 mol NaOH/1 L NaOH)
= 0.0050 mol NaOH
c) Calculate the <em>moles of HCl
</em>
Moles of HCl = 0.0050 mol NaOH x (1 mol HCl/1 mol NaOH)
= 0.0050 mol HCl
d) Calculate the <em>molar concentration</em> of the HCl
<em>c</em> = moles/litres = 0.0050 mol/0.050 L = 0.1 mol/L
Scratch Test is your answer
A scratch test is when one rubs a mineral on a piece of white tile, and sees what color is left behind. Also, the mineral that has the scratches is weaker than the material that leaves the scratch mark.
hope this helps
Moles of copper nitrate:-
- 1mol of Copper nitrate reacts with 2mol NaOH
- 0.001mol will react with 0.002mol NaOH
Madd of NaOH
Lovely song just asking is there a question so I don't get hate for not knowing rather there's a question or not
Answer:
o Surface Type- Because the atmosphere is heated by the Earth's surface, the surface type plays an important role in the surface air temperature. o Elevation and Aspect- Higher altitude generally has colder temps b/c the air is less dense and there are fewer molecules to absorb incoming solar radiation.
The Earth's surface is actually what heats the air above it.
Explanation:
The energy from the sun is "short-wave", and as such air is transparent to it. The sunlight goes right through the air without heating it at all. This "short-wave" radiation is absorbed by the Earth which then heats up. The heated Earth then emits it's own radiation but it is in the infrared part of the spectrum or "long-wave" radiation. This heat is what warms the atmosphere.
