A pot of water at 25°C is placed over a flame until it has boiled away. Which way is energy being transferred between the system
Hatshy [7]

Answer:

See explanation

Explanation:

According to the law of conservation of energy; energy is neither created nor destroyed but is converted from one form to another.

This means that energy can not be lost, we can trace the transfer of energy between a system and its surroundings.

When a pot of water at 25°C is placed over a flame until it has boiled away, energy is transferred from the pot (the system) to the surroundings hence the temperature of the surroundings rises accordingly.

How many mL of 0.013 M potassium hydroxide are required to reach the equivalence point in the titration of 75 mL 0.166 M hydrocy
umka21 [38]

Answer:

957.7mL

Explanation:

Using the formula below;

CaVa = CbVb

Where;

Ca = concentration of acid (M)

Va = volume of acid (mL)

Cb = concentration of base (M)

Vb = volume of base (mL)

According to the information provided in this question:

Ca = 0.166 M

Cb = 0.013 M

Va = 75mL

Vb = ?

Using CaVa = CbVb

0.166 × 75 = 0.013 × Vb

12.45 = 0.013Vb

Vb =12.45/0.013

Vb = 957.7mL

Explain how to write the chemical formula for sodium (Na +) and the polyatomic ion carbonate (Co2).
Lorico [155]

Explanation:

sodium (Na +)

Carbonate ion (CO₃²⁻)

Ionic compounds are formed between ions (Anions and Cations).

For a neutral compound to be formed, the charges of the ions must cancel each other out.

Sodium ion has a charge of +1

Carbonate ion has  a charge of -2

The only way to make sure both ions have similar charges is to multiply each ion by the coefficient of the other.

Thus we have;

Sodium ion = +1 * 2 = +2

Carbonate ion = -2 * 1 = -2

From this, the chemical formular of the product formed between both ions must contain 2 sodium ions and one carbonate ion.

This is given by;

Na₂CO3
