What type of tide would this arrangement of earth-moon-sun create?*
Advocard [28]

Answer:

neap tide

Explanation:

There are two different types of tides, which are the spring tide and the neap tide.

Neap tides are weak tides which occur when the gravitational forces of the sun and the moon are at right angles to each other with respect to the earth. Since the sun and moon are at right angles, it causes a difference between the low and high tide.

The spring tide are strong tides which occur when the moon, sun and earth are in straight line. The spring tide occur during full moon and new moon.

water is considered as a compound of hydrogen and oxygen and not a mixture of hydrogen and oxygen and comment on it
HACTEHA [7]
Wat is considered a compound of hydrogen and oxygen and not a mixture because hydrogen and oxygen have gone through a chemical process to form the compound h2O. A mixture can generally be easily separated whereas a compound must undergo another chemical process to separate its elements. Therefore to separate oxygen and hydrogen from water a chemical process is necessary.

The Earth's surface is colder than the air above it, what will happen to the air?
Nitella [24]

Answer:

If the earth's surface is cold, warm air above it will lose heat energy to the cold surface below and the now cool air will remain close to the surface. If a damp surface is warmer than the air above it, some water will evaporate, and the air above the surface will be heated.

9) A certain atom has 10 electrons, 14 neutrons, and 11 protons. Write the name of this element in isotope notation.​
Dimas [21]

Answer:

²⁵₁₁Na⁺

Explanation:

Details about the atom:

          Number of electrons  = 10 electrons

          Number of neutrons  = 14 neutrons

          Number of protons  = 11 protons

The atomic number of an atom is a good indicator of the type of atom we have been given.

From the subatomic particles, the number of protons is the same as the atomic number.

 Since the number of protons is 11, its atomic number will be 11.

The element with atomic number 11 is sodium, Na.

  To write a complete notation, we also need the mass number;

  Mass number  = number of protons + number of neutrons

  Mass number  = 11 + 14  = 25

 The charge on the atom:

     Charge  = Number of protons  - number of electrons  = 11  - 10  = 1+

The element in isotopic notation is given as;

                  ²⁵₁₁Na⁺
