Answer:

B. convection

Explanation:

The sun heats the atmosphere and the surface of the Earth causing convection currents to develop in the atmosphere due to heated air that rise into the atmosphere.The ocean itself regulates temperatures at the lower parts of the atmosphere thus ensures the circulation of water in the ocean through currents and waves.At the equator, heated air loses its density, making it to rise, and when it reaches the troposphere it spreads towards the pole by convection.

a sample of sucrose was burned in a calorimeter, and 41,600 joules oh heat energy were released. which statement is true about t
Gala2k [10]

It absorbed 41,600 joules.

Explanation:

If the sample of sucrose burnt in the calorimeter releases 41600Joules of heat, then the water in the calorimeter will absorb 41600J.

 The heat lost by burning the sucrose in the calorimeter is also the heat gained by the water therein.

A calorimeter is a device by prevents heat loss to the environment in any form.

It is specially designed to minimize heat loss by conduction, convection radiation.

Therefore, since no heat is lost, the heat released by burning the sucrose is used in heating the water there.

On the periodic table, calcium and bromine are located in period 4. What is one difference between the two elements?
Dovator [93]

Answer:

D

Explanation:

Just look at the groups and their tendencies. Or look at their electron configurations. You will notice that calcium has 2 valence electrons and bromine has 7 valence electrons.

Halogens have the most valence electrons possible without completing a shell (8 would be needed for that)

Given the balanced equation:
Aliun [14]

Answer:

0.4

Explanation:

Given data:

Number of moles of SrCl₂ consumed = ?

Mass of ZnCl₂ produced = 54 g

Solution:

Chemical equation:

ZnSO₄ + SrCl₂    →    SrSO₄ +  ZnCl₂

Number of moles of ZnCl₂:

Number of moles = mass/ molar mass

Number of moles = 54 g/136.3 g/mol

Number of moles = 0.4 mol

Now we will compare the moles of  ZnCl₂ with SrCl₂  from balance chemical equation.

                          ZnCl₂              :             SrCl₂

                              1                  :                1

                           0.4                 :              0.4

Thus when 54 g of  ZnCl₂ produced 0.4 moles of SrCl₂ react.
