Answer:
c. 2
Explanation:
The alkaline earth family is the second most reactive group, and it's elements can't be found free in nature. They are called "alkaline" earth metals because they form "alkaline" solutions, hydroxides, when they react with water
An atom has 15 electrons. How many are on each shell? *
0 2,8,7
0 2,8,5
8,7
15
Answer:
So... for the element of PHOSPHORUS, you already know that the atomic number tells you the number of electrons. That means there are 15 electrons in a Phosphorus atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and five in shell three.

Explanation:
Maria walked on a beach made mostly of sand. She walked barefoot
on the beach early in the morning, and the sand was cool. When she
walked in the same area in the afternoon, the sand was hot.
Which statement best describes why the temperature of the sand
increased?
The statement that the atoms in the sand were moving more quickly best describes why the temperature of the sand is increased. The relationship between kinetic energy and temperature is explained here.
What is the relationship between kinetic energy and temperature?The temperature of a body is directly proportional to the kinetic energy. The energy acquired by those molecules which are in motion is called the kinetic energy.
The radiation of the sun falls on a number of objects on our surroundings. The objects absorb this energy till afternoon due to which they become hot.
When Maria walked in afternoon, the sand was hot as its particles have gained the kinetic energy due to which they move rapidly from one place to another. So that the sand feels more hot in the afternoon.
Thus the atoms in the sand were moving more quickly best describes the increase in temperature of the sand.

In carbon dioxide, London dispersion forces are the only intermolecular forces of
attraction.
a. TRUE
b. FALSE
Answer:
true
Explanation:
CO has two C-O bonds. The dipoles point in opposite directions, so they cancel each other out. Thus, although CO₂ has polar bonds, it is a nonpolar molecule. Therefore, the only intermolecular forces are London dispersion forces.
The statue of Liberty is made out of copper metal. When it was first constructed, the color of the copper metal was bright burnt orange.
Over time, however, it slowly developed a green color as it was exposed to air. What happened to the statue of liberty?
Explanation:

A class investigated the reactivity of four metals by dropping little pieces of the
metals into solutions of their salts.
When there was a reaction they recorded a `Y’, when there was no reaction they
recorded an `N’.
Here is their table of results.From their results, which is the least reactive metal?
The least reactive metal is lead, since it reacted with none of the salt solutions.

Magnetic force is referred to as the force/phenomenon which is exerted by a magnet when they attract or repel each other through the poles. It's produced by an electric charge.There are 2 poles ⇨ i) North Pole & ii) South Pole.The like pole repel each other while the different poles attract each other. Magnetism is also known as magnetism or magnetic attraction.Which organelle captures sunlight and helps in food synthesis?

The diagram below shows four altitude locations on a mountain.
Which of these locations is most likely to experience the least amount of snow?
Location D
Location C
Location A
Location B
According to the diagram shown, location A will receive least amount of snow in the form of precipitation.
What is precipitation?
Precipitation is defined as any liquid or frozen water which forms in the atmosphere and then gets received on Earth.It is one of the most important steps of the water cycle.
Precipitation takes place in form of clouds when water vapor gets accumulated in clouds and they get bigger and heavy, when the clouds become heavy enough they fall to the land in the form of rain.If a cloud is present at higher altitudes , the water present in the clouds freezes and fall to the ground in form of snow,hail.
Precipitation occurs always in case of fresh water because the sea salt does not evaporate with the water.The different types of precipitation are rain, drizzle,snow,snow hail,etc.

What effects do winds patterns have on climate
Prevailing winds bring air from one type of climate to another. For example, warm winds that travel over water tend to collect moisture as they travel; the water vapor in the air will condense as it moves into colder climates, which is why temperate coastal areas often receive heavy rainfall.
