Answer:

10.0 g of AgI will produce 5.28 g of Ag₂S

Explanation:

The balanced equation of the reaction is given below:

2AgI + Na₂S ----> Ag₂S + 2NaI

From the equation of reaction, 2 moles of AgI produces 1 mole of Ag₂S

The moles of a substance is related to its mass by a quantity known as molar mass which is defined as the mass of one mole of that substance.

Molar mass of AgI = (108 + 127) g = 235 g

Molar mass of Ag₂S = (108 × 2 + 32) g= 248 g

Mass of 2 moles of AgI = 2 × 235 g = 470 g

470 g of AgI produces 248 g of Ag₂S

10 g of AgI will produce 248 /470 × 10 g of Ag₂S = 5.28 g

Therefore, mass of Ag₂S produced = 5.28 g

Answer: (3) silicon

Explanation:

Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions.Example: Silicon (Si)

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: ethane $(C_2H_6)$ , propanone $(CH_3COCH_3)$ and water $(H_2O)$

assuming that each human being has 60 trillion body cells in that the earths population is 6 billion calculate the total number

sesenic [268]

3.6 x 10²³

Explanation:

Given parameters:

Number of cell per body = 60 trillion body cells

Population of the earth = 6 billion

Unknown:

Total number of living human body cells = ?

Solution:

To solve this problem, simply find the product:

Total number of living human body cells = number of cell per body x population of the earth

1 trillion = 1 x 10¹²

60 trillion = 6 x 10¹³

1 billion = 1 x 10⁹

6 billion = 6 x 10⁹

Total number of living human body cells = 6 x 10¹³ x 6 x 10⁹

= 6 x 6 x 10⁽¹³⁺⁹⁾

= 36 x 10²² or 3.6 x 10²³
