<u>Answer:</u>
<em>We know water can exist in all three states be it solid or liquid or gas the only difference between the three states is the temperature at which they exist. </em>
<u>Explanation:</u>
When the temperature moves towards colder region the state of water changes to solid while when the temperature moves to water region the state of water changes to gas.
This little experiment can be done with the help of ice at room temperature. The more ice is applied to water it will turn to ice but removal of eyes in room temperature. And will make it turn to water and complete removal of eyes with application of heat would make it into vapour.

<h2>The symbiotic relationship that occurs between an orchid and a tree would be classified as commensalism. Most orchids are epiphytes, which mean that that they grow on other plants. This benefits the orchids because they can grow on top of the canopy, which prevents the orchids from being walked on or eaten by ground-dwelling organisms.</h2><h3 /><h3>I HOPE TO IT'S HELP YOU:)</h3>
Answer:
1. 2+ ().
2. 0 ().
Explanation:
Hello,
In this case, the described chemical reaction is a redox reaction in fact, since the oxidation states of both magnesium and copper change as shown due to the displacement:
Therefore:
1. Since copper is the cation in the copper (II) nitrate, the (II) means that its charge is 2+ ().
2. Since copper is alone, it means no electrons are being neither shared not given, its charge is 0 ().
Best regards.
1. An ion is a charged atom. A molecule is a neutrally-charged combination of atoms.
2. A molecule is a combination of atoms. It can consist of atoms from one or more elements. For example, an oxygen molecule comprises two oxygen atoms. A compound is a substance made up of a combination of atoms of different elements. For example, water is a compound of hydrogen and oxygen.
3. An electron dot diagram is a simple way of representing the bond and electronic structure of molecules. A formula is a written representation of the types and numbers of atoms in a molecule.
4. As above...a formula denotes which atoms are in a molecule and how many. For example, H2SO4 tells us there are two hydrogen atoms, one sulfur atom and four oxygen atoms in each molecule of sulfuric acid.
5. An ionic bond is a type of chemical bond that stems from electrostatic attraction between ions with opposite charges. A covalent bond is another type of chemical bond that involves sharing of electrons between atoms in order to achieve a stable electronic structure for the molecule as a whole.
Answer:
11,000 cm
Explanation:
Step 1: Given data
Width of the field (w): 17 meters
Length of the field (l): 38 meters
Step 2: Calculate the perimeter of the field
The field is a rectangle. We can find its perimeter (P) by adding its sides.
P = 2 × w + 2 × l = 2 × 17 m + 2 × 38 m = 110 m
Step 3: Convert the perimeter to centimeters
We will use the relationship 1 m = 100 cm.
110 m × (100 cm/1 m) = 11,000 cm
