Answer:
the molarity of NaOH is 1.10. And the molarity of HCl is 1.10. And the initial Temp=0.50(°c). and The final Temp= 1.10(°c)
Birds use the magnetic fields and some fish i believe as well and maybe butterflies im not entirely sure <span />
Answer:
0.86 g/mL
Explanation:
In order to solve the problem, you have to know the formula for "Density." Density refers to<em> </em><em>"mass per unit volume." </em><em>It's formula is:</em>
- <em>Density (ρ) = </em>
<em />
Next, we have to convert the units of measurement in accordance to what is being asked in the problem. It is asking for "g/mL," which means we have to convert 1.25 quarts<em> (qt.) </em>to mL and 2.25 pounds<em> (lbs.)</em> to grams.
Let's solve.
1.25 qt. x
=<em> 1,182.94 mL</em>
2.25 pounds x
= <em>1,020.58 grams</em>
Now that we converted them to their appropriate units of measurement, we can now solve for density.
- <em>ρ = </em>
<em />
- <em>ρ = </em>
<em />
<em>The density of the motor oil is 0.86 g/mL</em>
Protons: <span>The mass of the proton is about 1,840 times the mass of the electron and slightly less than the mass of the neutron.
Electrons: </span><span>Electrons are arranged around the nucleus of atoms in regions called electron clouds or electron orbits.
Neutrons: </span><span>A neutron is one of two particles found inside the nucleus (central part) of an atom. The other particle is called a proton. Electrons are particles that move around an atom outside the nucleus.</span>
