- Determining Chemical Compounds
Explanation:
<u>Step 1: Define</u>
Scandium (II)
Cl
<u>Step 2: Determine Charges</u>
Sc²⁺
Cl⁻
<u>Step 3: Predict Compound</u>
<em>We need to balance out the charges so the overall charge is 0.</em>
ScCl₂
<u>Step 4: Reaction</u>
RxN: Sc²⁺ + Cl₂ → ScCl₂
0.05 liters of 0.40 M calcium chloride solution
Explanation:
We have the following chemical reaction:
Na₂CO₃ + CaCl₂= 2 NaCl + CaCO₃
Chalk is calcium carbonate CaCO₃.
number of moles = mass / molecular weight
number of moles of CaCO₃ = 2 / 100 = 0.02 moles
From the chemical reaction we see that 1 mole of calcium chloride (CaCl₂) produces 1 mole of calcium carbonate (CaCO₃), so to produce 0.02 moles of calcium carbonate (CaCO₃) we need 0.02 moles of calcium chloride (CaCl₂).
molar concentration = number of moles / volume (L)
volume = number of moles / molar concentration
volume of calcium chloride solution = 0.02 / 0.4 = 0.05 liters

<em>A conductor allows current to flow easily through it. An Insulator doesn't allow current to flow through it. Electric charge exists on the surface of conductors. Electric charges are absent in insulators.</em>
Answer:
yes it can be attracted without touching The electric force is a non-contact force. Any charged object can exert this force upon other objects - both charged and uncharged objects.
Explanation:
Answer:
it's a mixture
Explanation:
I literally just went on Google google and type that in. if you're in highschool I got some links for you I got some alot of helpful websites with math, science, social science, and highschool year of course, biology, geometry, Algerbra, and any other class you're taking. if you don't want them just type no.
