When Lead (II) acetate and Hydrogen sulfide react, they form Lead sulfide and Acetic acid. The reaction is a reduction-oxidation (redox) reaction.
The balanced chemical reaction is this:
Pb(C2H3O2)2 + H2S --> PbS + 2C2H4O2
And the net ionic reaction is this:
Pb2+ + S2- --> PbS
Answer:
Diabetes is a group of diseases that affect how your body uses blood sugar (glucose). Glucose is vital to your health because it's an important source of energy for the cells. Cells are everywhere including the blood, bones and muscles. When you have diabetes, you don’t have enough insulin in your blood (an organ in your body called the pancreas makes insulin). Insulin controls the movement of blood sugar into the cells of the body.
Explanation:
Answer:
λ = 6.25 × 10⁻¹⁰ m
x-ray
General Formulas and Concepts:
Speed of Light = Wavelength times Frequency
Explanation:
<u>Step 1: Define</u>
C = 3.0 × 10⁸ m/s
ν = 4.80 × 10¹⁷ Hz (s⁻¹)
λ = unknown
<u>Step 2: Solve for wavelength</u>
3.0 × 10⁸ m/s = λ(4.80 × 10¹⁷ Hz)
λ = 6.25 × 10⁻¹⁰ m
<u>Step 3: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules.</em>
6.25 has 3 sig figs. No changes necessary.
<u>Step 4: Identify</u>
6.25 × 10⁻¹⁰ m is in the x-ray spectrum according the the Electromagnetic Spectrum
No, this number is the result of the natural mixture of Cl-35 and Cl-37, which produces the observed <span>value.
</span><span>The mass of Cl on the periodic table is 35.45 atomic mass units. This is an average mass of the isotopes (different Cl atoms in nature). Most Cl atoms in nature have a relative mass of about 35 atomic mass units. Most of the remaining Cl isotopes have a relative mass of 37 atomic mass units. </span>
Answer:
salt
Explanation:
When acid and base solutions react, they produce water and a neutral ionic compound called a salt.
