The equation that shows the decomposition of silver carbonate are;

2Ag2CO3 ---------> 4Ag + 2CO2 + O2

From the periodic table:

Mass of silver = 107.8682 grams

Mass of carbon = 12 grams

Mass of oxygen = 16 grams

Molar mass of Ag2CO3 = 2(107.8682) + 12 + 3(16) = 275.7364 grams

From the balanced equation above:

2(275.7362) = 551.4728 grams of Ag2CO3 produces 4(107.8682) = 431.4728 grams of Ag

Thus, in order to know the mass of Ag produced from 2.76 grams of Ag2CO3, we'll use the cross multiplication method;

Mass of Ag produced = (2.76 × 431.4728) / (551.4728) = 2.16 grams

Based on the calculations demonstrated above, the law of conservation of mass is applied.

Which type of epithelium is composed of multiple layers, including an apical layer containing tall, slender cells?

Mademuasel [1]

The question is incomplete as it does not have the options which are:

Simple squamous
Simple columnar
Pseudostratified squamous
Stratified squamous
Stratified columnar

Answer:

Stratified columnar

Explanation:

Epithelial tissue is the tissue formed by the cells which form a layer of cell and lines the lumen of the organ and also covers the organs. The epithelial tissue can be classified based on the number of layer and shape of the cell.

In the given question, the shape of the cell is slender and are tall therefore are called columnar. The cells form more than one layer or multiple layers therefore form stratified layers.

Therefore, the epithelial tissue formed by these slender shaped multiple layers is known as the stratified columnar layer. The stratified columnar is present in the respiratory tract and the digestive tract.

Thus, Stratified columnar is the correct answer.

Which of the following terms are NOT used interchangeably? muscle tension - muscle force in vivo - in the body/ the living muscl

Karo-lina-s [1.5K]

Answer:

The correct answer is "motor unit - motor neuron".

Explanation:

Motor unit and motor neuron are related terms, however they could not be used interchangeably because a motor unit is not comprised only of a motor neuron. A motor unit is made of a motor neuron, skeletal muscle fibers and neuron's axonal terminals. Therefore motor unit is a more broadly term, and is referred to the units that coordinate the contractions of single muscles.

Name on ion that have entered the plant by diffusion. Explain your answer

Anna11 [10]

Answer:

Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.
