Answer:

Different compounds react with oxygen differently – some contain lots of heat energy while others produce a smaller amount. The reaction with the oxygen may happen very quickly or more slowly. Amount: The amount of fuel available to burn is known as the fuel load.

Which wind blows cool air toward the sea at night ?
alexira [117]

Answer:

Land breeze is the wind that blows cool air from land towards sea at night.

Explanation:

Land breeze is a type of wind which is cool and blows towards sea. It occurs due to the difference in the temperature of water and land. At night, the lands cool quickly due to the removal of heat from it. So the air that is present on land is cool down and this air moves towards sea. So this breez is called land breeze because it moves from land.

A student made the Lewis dot diagram of a compound as shown. Mg is written with two dots shown on its top. Cl is written on the
blsea [12.9K]

Answer:

The dots were not properly located and arrows are not used in Lewis structures

Explanation:

If we intend to write a Lewis structure for a compound, that lewis structure must consist of only dots. These dots actually show the valence electrons on the outermost shell of the molecule.

We do not involve arrows when writing dot electron structures for compounds. The valence electrons of magnesium ought not to be written together because they are not a lone pair, rather they are two unpaired electrons. The use of an arrow suggests a coordinate covalent bond which is not the case here.

The correct lewis structure for MgCl2 is shown in the image attached to this answer.

Convert the following into balanced equations:
sesenic [268]

Gallium metal is heated in oxygen gas, it melts and forms solid gallium(III) oxide.

             Ga + O₂⇒   Ga O₂

Balance the atoms with simple - whole coefficients.

4 Ga + 3 O₂   2 Ga₂O₃.

Specify the states of matter.

4 Ga(s)  + 3 O₂ (g) ⇒   2 Ga₂O₃.(s)

Therefore, balanced equation is----- 4 Ga(s)  + 3 O₂ (g)  ⇒ 2 Ga₂O₃.(s)

What is the balanced formula equation?

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.

Why are equations balanced?

A balanced equation obeys the Law of Conservation of Mass. This is an important guiding principal in science. Finally, a balanced equation lets up predict the amount of reactants needed and the amount of products formed.
