A common dry-cell battery is the zinc-carbon battery, which uses a cell that is sometimes called the Leclanché cell. The cell is made up of an outer zinc container, which acts as the anode.

Answer:

Graphite

Explanation:

An electrode is a solid electric conductor (usually metallic) used in electrolytic cells for carrying electric current. An electrolytic cell is made up of electrodes and electrolytes. There are two types of electrodes

  • Anode - attracts negatively charged ions (anions)
  • Cathode - attracts positively charged ions (cations)

The common dry cell is the transistor battery. The cylindrical coating of this cell is made up of zinc which serves as the anode while the center electrode which is the graphite is the cathode. Graphite is one of the allotropes of carbon and it is a good conductor of electricity.

An electrolyte is a liquid/aqueous solution that allows the passage of electric current. The electrolyte in this cell is usually made up of manganese dioxide (MnO₂),  carbon powder and ammonium chloride (NH₄Cl).

A chemical reaction is at equilibrium. what will be the effect if more of the product is added? question 10 options: the reactio
VashaNatasha [74]

The answer is <span>the reaction will shift to the left (toward the reactants).

Reaction is at equilibrium can be expressed as,
      Reactants </span>⇄ products<span>

<span>After coming to the equilibrium, if one condition is changed, then according to the </span>Le chatelier's Principal,<span> the system will act to maintain the equilibrium by reducing the effect. As an example, if we reduce the pressure, then system acts to increase the pressure to maintain the equilibrium.</span>

<span>Likewise, if we add products into the reaction which is in equilibrium, the system acts to reduce the effect by promoting the backward reaction to produce reactants.</span></span>

An aqueous solution containing 100.0 g of nacl and 100.0 g of cacl2 has a volume of 1.00 l and a density of 1.15 g/ml. the vapor
Lemur [1.5K]
Missing question: What is the vapor pressure of the solution at 25°<span>C?
n(NaCl) = 100 g </span>÷ 58,4 g/mol.
n(NaCl) = 1,71 mol. 
NaCl → Na⁺ + Cl⁻, amount of ions are 2 · 1,71 mol = 3,42 mol.
n(CaCl₂) = 100 g ÷ 111 g/mol = 0,9 mol.
CaCl₂ → Ca²⁺ + 2Cl⁻, amount of ions 3 · 0,9 mol = 2,7 mol.
m(solution) = 1000 ml (1,00 L) · 1,15 g/ml = 1150 g.
m(H₂O) = 1150 g - 100 g - 100 g = 950 g.
n(H₂O) = 950 g ÷ 18 g/mol = 118,75 mol.
<span>water's mole fraction = 118,75 mol </span>÷ (118,75 mol + 2,7 mol + 3,42 mol).
water's mole fraction = 0,95.
p(solution) = 0,95 · 23 mmHg = 21,85 mmHg.

What do I write? Please hurry
scoundrel [369]

Answer:

Plants wilt when the turgor turns to zero. From diminished water in cells. The rate of water being lost is greater then the water being absorbed.

Something like this. NOT EXACTLY THIS this is just an example.

I didn't know anything about this topic but I looked it up. For the other words I would look up the other words and see what they have to do with plants withering.

Write the net ionic equation for the reaction of sodium phosphate with iron (III) chloride. Include the complete ionic equation
Xelga [282]

Hi There!

Question - Write the net ionic equation for the reaction of sodium phosphate with iron (III) chloride. Include the complete ionic equation and label the spectator ions. Also be sure to label the reactants as products as solid, liquid, gas, or aqueous solutions

Answer: Fe3(+) + PO43(-) = FePO4

P.S. The + and - are in parentheses because they are below the number.

Hope This Helps :)
