If aluminum loses 3 electrons how do you write the ion

Answers

Answer 1

Answer: Since it has lost 3 electrons that means it now has excess protons of 3 protons.

So it is positive. You write it as:

Al³+.

The plus sign should be on the same line with the 3.

How might human activities change to compensate for a decrease in water supplies?Humans might build a factory.
Humans might build drainage systems.
Humans might extract more water from the ground.
Human behavior does not change because of the water cycle.

Answers

Answer: Humans might extract more water from the ground.

Explanation:

Humans may face the situations of unavailability of water supply. Majority of the human population is dependent upon the source of water like oceans, lakes, rivers, ponds and wells for their water supply.

But in the scarcity of water from the drainage supply by the water body human population should search for a relevant alternative such as groundwater. Groundwater is the underground reservoir of water. The water in the groundwater reservoir accumulates from the sources such as rainfall, snow melting, river and oceanic water.

Humans should search for groundwater reservoir for compensating the scarcity of water.

You have been given an orange liquid and told to describe its properties. What methods would you use to observe, measure, and describe the physical properties of this orange liquid without changing it?

Answers

From observing the liquid you can get the following information: the color, the state of matter, the smell and the fluidity [that is, does it flow freely or it is viscous in nature].
By measuring, you can get the volume of the liquid using measuring cylinder. You can also determine the temperature of the liquid at the room temperature using thermometer.

How does ur body maintain constant tempature on a hot day?

Answers

It knows that when water evaporates, it carries heat energy away with it.
So your body puts some water out on your skin, and hopes that it will
evaporate. We call that "perspiring" or "sweating".

Answer:

your skin opens up

Explanation:

the pores i your skin opens up and let the water (sweat) out to help cool down your body.

Which statement best defines a universal law

The law of attraction in physics Newton's gravitational pull means to lie close to each other. In the field of physics of each object with mass m1 always have attractive forces with another object (with mass m2). For example, a particle with other particles will always mutual attraction. Examples put forward by Sir Isaac Newton in the field of classicalmechanics that anything on the atmosphere will be pulled by the earth,which was then known as the phenomenon of falling objects.

Attractive force of gravity is expressed by Isaac Newton viaWriting in the journal Philosophiæ Naturalis Principia Mathematica onJuly 5, 1687 in the form of the following formula:

    F = G \ frac {M_1 m_2} {r ^ 2},

Where:

    F is the force of gravity between the two masses,
    G is the gravitational konstante,
    m1 is the mass of the first object
    m2 is the mass of the object, and
    r is the distance between the two masses.

Thistheory is then developed further that any celestial body will be mutualattraction, and this could explain why the earth should revolve aroundthe sun to offset the attractive force of gravity of the earth-sun. Byusing the gravitational pull of this phenomenon as well, meteors closerto the Earth in its journey in space will be attracted fall to earth.
