Answer : The correct location on the periodic table of two elements have similar characteristics is, two elements present in the second column of the left side

Explanation :

The elements have similar characteristics when they are belong to the same family or group this means that when they are placed in the same column of the periodic table.

The elements of similar characteristics have same number of valence electrons.

In the given periodic table of the elements, the two elements present in the second column of the left side have similar characteristics because these two elements belong to the same family or group. While the other elements have different characteristics.

Explanation:

It is known that atoms that have same number of valence electrons will show similar chemical properties.

So, when we move from left to right across a period there occurs increase in number of valence electrons of each element. But when we move down a group then number of valence electrons remain the same.

Hence, elements of same group will show similar chemical properties.

Therefore, we can conclude that elements marked as 2 and 3 will have similar chemical properties.

Metals have a low electron affinity- a less likely chance to gain electrons because they want to give up their valence electrons rather than gain electrons, which require more energy than necessary.

How many moles of Fe2O3 are in 203 g of the compound?

ruslelena [56]

The equation is :
moles=mass/molar mass
so, the mass is 203 and molar mass is 159.69
You divide the 203 by 156.69 as the equation shows
so the moles is 1.27 mol.

The Coriolis effect influences _____. neither wind speed nor wind direction wind speed both wind speed and wind direction wind d

Alona [7]

Answer: The correct answer is "wind direction".

Explanation:

Coriolis effect: This is an apparent deflection of moving air or water caused by the rotation of the earth.

Currents are created by wind. Their directions are determined by Coriolis effect.

Currents are created by wind. The earth is in constant motion. It describes the rotation of the earth which steers winds and the surface current. The ocean surface currents are deflected by Coriolis effect.

The direction of the wind blows from north and south towards equator.

Therefore, the Coriolis effect influences wind direction.
