Answer: Option (B)

Explanation: Wind pattern in the earth shows the same convection current mechanism like the one that takes place in case of plate tectonic movement.

            In the equatorial region, the air becomes warm, less denser and eventually rises up to the atmosphere and falls at the tropics (30° N and S latitude) of both the hemisphere.

               Similarly at 60° latitude in both the hemisphere, the warm air rises up and converges at the poles of the two end.

 Thus, the wind pattern in earth is comprised of convection current mechanism.

What type of reaction is shown below: Br2 + Kl 12 + KBr​
bonufazy [111]

Answer:Chemical reaction

Explanation:

The main concept that must be applied to determine the coefficients (amount of each item) is that there must be equal amounts of each element on each side of the equation. We are not destroying or creating new atoms. In this case, the unbalanced reaction formula is:

B

r

2

+

K

I

=

K

B

r

+

I

2

There are a two problems we need to solve before it will be balanced:

There are two moles of Iodine atoms (

I

) on the right side of the equation, while there is only one mole on the right side.

There are two moles of bromine (

B

r

) atoms on the left side, while there is only one on the right.

Since there are two moles of bromine atoms on the left side, we need two moles on the right as well. We can do this by adding a coefficient of two to the

'

K

B

r

'

term in the equation. Our now modified equation looks like this:

B

r

2

+

K

I

=

2

K

B

r

+

I

2

There is one mole of Iodine atoms on the left, and two on the right. To fix this, we add a coefficient of two to the

'

K

I

'

term. The resulting equation is below.

B

r

2

+

2

K

I

=

2

K

B

r

+

I

2

Bonus step: We can also put ones in front of the coefficient-less species. This is like changing a phrase from "an apple" to "1 apple". It is the exact same thing, but makes it a little more clear sometimes. This would like like this:

1

B

r

2

+

2

K

I

=

2

K

B

r

+

1

I

2

Can you see that there is now an equal amount of each element on each side of the equation? That means that it is balanced.

How many moles of butane gas, C4H10, react to produce 2.50 moles of H2O? How many moles of oxygen gas reacts? Given the balanced
viva [34]
The moles  of  butane gas  and  oxygen gas reacted  if  2.50  moles  of H2O is produced  is  calculated  as below

the  equation  for  reaction
2C4H10  +13 O2 = 8CO2 +10 H2O

the moles  of  butane (C4H10) reacted calculation

by  use  of mole ratio between  C4H10: H2O  which  is  2  : 10 the  moles of  C4H10=     2.50  x2/10 = 0.5 moles  of  C4H10  reacted

The  moles of  O2  reacted calculation

by  use of mole  ratio  between   O2 : H2O  which  is  13:10 the moles of O2

=   2.50  x 13/10=  3.25  moles of O2  reacted
