Answer:

chemical cells that produce an electrical current

Explanation:

lead acid battery is a type of chemical cell, that discharges to produce electrical current.

lead acid battery uses lead peroxide for the conversion of the chemical energy into electrical power when it is discharging. It is also rechargeable, that is, it can convert electrical energy back to chemical energy during charging.

Thus, a discharging lead acid battery is best described as a chemical cells that produce an electrical current

Answer:

The correct option is;

2.) Chemical cells that produce an electric current

Explanation:

A discharging lead-acid battery is an electrochemical cell that produces electrical energy through the chemical reaction taking place at the battery electrodes which have lead as the anode and lead oxide as the cathode which result in the flow of an electric current, thereby converting chemical energy of the lead, lead oxide and aqueous sulfuric acid system into electrical energy, therefore, it is a chemical cell that produces an electric current.

A sample of an ionic compound that is often used as a dough conditioner is analyzed and found to contain 4.628 g of potassium, 9

Roman55 [17]

Answer:

The empirical formula of the compound is = $KBrO_3$

The name of the compound is potassium bromate.

Explanation:

Mass of potassium = 4.628 g

Moles of potassium = $\frac{4.628 g}{39 g/mol}=0.1187 mol$

Mass of bromine = 9.457 g

Moles of bromine = $\frac{9.457 g}{80 g/mol}=0.1182 mol$

Mass of oxygen = 5.681 g

Moles of oxygen = $\frac{5.681 g}{16 g/mol}0.3551$

For empirical formula of the compound, divide the least number of moles from all the moles of elements present in the compound:

Potassium :

$\frac{0.1187 mol}{0.1182 mol}=1.0$

Bromine;

$\frac{0.1182 mol}{0.1182 mol}=1.0$

Oxygen ;

$\frac{0.3551 mol}{0.1182 mol}=3.0$

The empirical formula of the compound is = $KBrO_3$

The name of the compound is potassium bromate.

The immediate source of energy that powers a cell’s activities is

Alja [10]

<span>1. The correct option is ADENOSINE TRIPHOSPHATE, ATP. ATP is the basic unit of energy transfer in the living cells. ATP is the principal energy source for metabolic functions, in the cells, ATP are consumed by endothermic metabolic reactions and they are produced by exothermic metabolic reactions.

2. To form ATP, A THIRD PHOSPHATE GROUP HAS TO BE ADDED TO ADP. ADP has two phosphate groups while ATP has three phosphate group. ADP is usulally converted to ATP by the addition of a single phosphate group.

3. ADP and ATP work together and the two can be interconverted. ATP can be hydrolysed to ADP and ADP can be converted to ATP by the addition of a single phosphate group. When energy is needed inside a cell, the ATP will split off one of its phosphate group and become ADP. This split off process produce a high qunatity of energy which is then available for the cell to use.</span>
