Which one of the following Acids is most likely to hurt you? Acid A: 1.0 M; Acid B: 0.0001M

Chemistry

vaieri [72.5K]3 years ago
7 0
Acid A, assuming the two acids have the same pH. The M stands for molarity which is how concentrated a substance is (basically the higher the molarity the more concentrated the acid is). However, pH refers to how acidic a substance is. If the two acids have different levels of acidity, the answer may be different.

Consider the following voltaic cell:(b) In which half-cell does oxidation occur?
damaskus [11]

At the anode, half-cell oxidation occurs in a voltaic cell.

<h3>Voltaic Cell Principle</h3>

A voltaic cell generates electricity due to the Gibbs free energy of spontaneous redox processes occurring inside the cell, which is the basis for the voltaic cell's operating principle.

Two half-cells plus a salt bridge make up the voltaic cell. An electrolyte-immersed metallic electrode is present on each side of the cell. These two half-cells are wired together to form a connection to a voltmeter.

<h3>Voltaic Cell Parts</h3>
  • Copper makes comprises the cathode of a photovoltaic cell. This electrode serves as the cell's positive terminal, where reduction takes place.
  • Anode: Zink metal makes up this electrode. It creates the cell's negative electrode, where oxidation takes place.
  • Oxidation and reduction are divided into two discrete parts in two half-cells.
  • Salt Bridge: It contains the electrolytes needed to finish the circuit in the voltaic cell.
  • The flow of electrons between the electrodes occurs via the external circuit.

If the spin of one electron in an orbital is clockwise, what is the spin of the other electron in that orbital?
umka2103 [35]

Answer:

The other electron must have anticlockwise spin.

Explanation:

According to the pauli exclusion principle, the two elecrton present in same orbital must have opposite spin.

If the one electron is clockwise the other must be in anti clockwise direction. The clockwise direction is represented by the sign +1/2 while anti clockwise direction is represented by -1/2.

According the pauli principle, the two electrons must have different fourth electronic quantum number. The electron in same orbital have same first three quantum number i.e, n=1 l=0 and ml =0 in case of first subshell.

A chemical reaction takes place in which energy is absorbed. Arrange the characteristics of the reaction in order from start to
marshall27 [118]
Endothermic reactions, on the other hand, absorb heat and/or light from their surroundings. For example, decomposition reactions are usually endothermic. In endothermic reactions, the products have more enthalpy than the reactants. Thus, an endothermic reaction is said to have a positive<span> enthalpy of reaction. This means that the energy required to break the bonds in the reactants is more than the energy released when new bonds form in the products; in other words, the reaction requires energy to proceed.</span>

Assume that consumer spending increased by $4 billion while unsold business production aimed at consumers increased by $6 billio
Natali5045456 [20]

Answer:

The correct option is;

B. Increase by $4 billion

Explanation:

In Gross Domestic Product, (GDP) calculation based on the spending or expenditure approach, the spending components of the countries different economic groups are calculated

The formula for the GDP can be expressed as follows;

GDP = C + G + I + NX

Where;

C = Consumer spending or private sector consumption

G = Spending by the government

I = Economic investment

NX = Net export of goods by the economy.
