Why does spring tides occur

Chemistry
1 answer:
g100num [7]3 years ago
8 0

Answer:

Because the Moon and the Sun are along the same line with the Earth

Explanation:

Tides are phenomenon that occur periodically on Earth. The term "tides" refer to the increase/decrease in the sea level in oceans and seas due to the combined effect of the gravitational force of the Moon and of the Sun on the water on Earth. In fact, the Moon (and the Sun also) exerts an attractive gravitational force on the water in the oceans, causing the sea level to rise when the Moon is facing that portion of water.

In particular, two types of tides are possible:

- Spring tides: these occurs when the Moon and the Sun are along the same line. In this situation, the gravitational forces exerted by the Moon and the Sun on the water act along the same line, so the combined effect is to increase the amount of tide, so the sea level rises more.

- Neap tides: these occurs when the Moon and the Sun are at 90 degrees from each other, with respect to the Earth. As a result, the gravitational force exerted by the Moon and the Sun on the water act perpendicular to each other, so the combined effect of the tide on the water is less than the spring tides, so the sea level is lower than the spring tides.

The number main-group elements'valance electrons can be determined by____ on the periodic table​
Zanzabum
<h2>Answer:</h2>

Valance electrons can be determined by <u>Group</u> on the periodic table​

<h2>Explanation:</h2>
  • Valence electrons are the electrons present in the outermost shell of an atom. We can determine the total number of valence electrons present in an atom by checking at its Group in which it is placed in the periodic table. For example, atoms in Groups 1 the number of valence electron is one and for group 2 the number of valence electrons is 2.
  • The groups have number of valance electrons as follow:

Group 1 - 1 valence electron.

Group 2 - 2 valance electrons.

Group 13 - 3 valence electrons.

Group 14 - 4 valance electrons.

Group 15 - 5 valence electrons.

Group 16 - 6 valence electrons.

Group 17 - 7 valence electrons.

Group 18 - 8 valence electrons.

Result: No of valence electron can be determined by the group no. of the element.

??? Ipc helppp pllzz
Umnica [9.8K]
The correct answers are
-formation of a precipitate
-bubble formation
-color change
-temperature change
-odor formation

The only one that isn’t correct is change in state of matter. A change in a state of matter does not mean it’s a chemical change. For example, water boiling so it turns into gas is not a chemical change, and is a physical one. Also, water can freeze and turn into ice, which is also still a physical change. If something changes state of matter, it does not necessarily mean it’s a chemical change.

suter [353]

Answer: The possible molecular formula will be CO_2

Explanation:

Mass of C= 27.3 g

Mass of O = 72.7 g

Step 1 : convert given masses into moles.

Moles of C =\frac{\text{ given mass of C}}{\text{ molar mass of C}}= \frac{27.3g}{12g/mole}=2.275moles

Moles of O =\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{72.7g}{16g/mole}=4.544moles

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For C = \frac{2.275}{2.275}=1

For O =\frac{4.544}{2.275}=2

The ratio of C : O = 1: 2

Hence the empirical formula is CO_2

The possible molecular formula will be=n\times CO_2
