The answer is D only metals are shiny and highly malleable

Answer: Option (D) is the correct answer.

Explanation:

Metals are the substances which donate electrons to complete their octet. They are malleable and ductile in nature. They are able to conduct heat and electricity. Metals have shiny surface and sonorous in nature.

Metals are placed at the left and middle of periodic table.

Whereas non-metals are the substances which accept electrons to complete their octet. They are poor conductors of heat and electricity. They are brittle and non-sonorous in nature.

Non-metals are placed at the right of periodic table.

Hence, we can conclude that right or middle of the table because it is a metal best explains the probable position of the substance in the periodic table.

Calculate the pH of a solution with an H+ ion concentration of 9.36 x 10-3 M ?
mel-nik [20]

Answer:

The answer is 2.03

Explanation:

The pH of a solution can be found by using the formula

pH = - log [ {H}^{+} ]

where H+ is the Hydrogen ion concentration

From the question we have

pH =  -  log(9.36 \times  {10}^{ - 3} )  \\  = 2.02872415...

We have the final answer as

<h3>2.03 </h3>

Hope this helps you

How does a greenhouse keep radiant energy from escaping?
Rina8888 [55]
Greenhouse effect is the process of trapping sun radiation in the earth surface, so as to make the planet warm. It is a natural phenomenon in which sun rays that enters the earth surface are re-radiated into the earth surface causing the heat trap in the earth.
In similar manner, green house also trap radiation inside the glass house. The sun rays once reach inside the glass house, strike on plants and objects and reflected back. For entire radiation to escape from the green house, the heat flow between the two points must be proportional to the temperature difference and thermal conductivity. The glass of which the green house are made up, have low thermal conductivity. So, temperature must rise inside glass house so to maintain the heat flow rate of incoming and outgoing radiation.
The green house glass are insulated and they trap the infrared emitted by the objects inside the green house from escaping outside. Since the infrared have longer wave lengths, it is released slowly. 

Also, the thermal energy inside the glass house are transferred by convection process. But the glass walls and roof act as insulator, keeping the radiant energy from escaping outside the green house.<span />

If the valency of oxygen is 2, derive the valencies of the other elements present in the following oxides. Na2O, ZnO , Al2O3 , M
11Alexandr11 [23.1K]

Answer:

1)Na2O

let the valency of Na is x

2(x)+(2)=0

2x+2=0

2x=-2

x=-1

2)ZnO

let the valency of Zn is x

x+2=0

x=-2

3)Al2O3

let the valency of Al is x

2(x)+3(2)=0

2x+6=0

2x=-6

x=-3

4)MgO

let the valency of Mg is x

x+2=0

x=-2
