2. Describe the property of water that is indicated
by the data. How is this property explained by the
structure of water molecules and the bonds
between them?
Answers
Answer:
The correct answer is - high specific heat.
Explanation:
Water atoms are polar, so they structure hydrogen bonds. This gives water remarkable properties, for example, a moderately high specific heat, density, adhesion, and cohesion.
A water particle comprises of two hydrogen iotas clung to an oxygen molecule, and its general structure is bowed. Oxygen even bonding with hydrogen have two sets of unshared electrons. The entirety of the electron pair and unpaired repulse one another.
Water's high specific heat is a property brought about by hydrogen holding among water particles. At the point when warmth is assimilated, hydrogen bonds are broken and water atoms can move uninhibitedly. At the point when the temperature of water diminishes, the hydrogen bonds are shaped and discharge a lot of vitality.
Thus, the correct answer is - high specific heat.
The property of water described by the heating curve is high specific heat capacity.
The specific heat capacity of a substance refers to the quantity of heat required to raise the temperature of 1 Kg of the substance by 1°C. The higher the heat capacity of a body, the greater the quantity of heat required to raise the temperature of 1 Kg of the substance by 1°C.
Looking at the heating curve, we can see that water has a very high heat capacity because a large quantity of heat is required to raise its temperature by 1°C. This is because of strong intermolecular hydrogen bonding between the molecules of water which leads to molecular association and high boiling point.

What is the significance of the water loss?Water is the most important component of life because it is used in almost all processes, and animals and plants contain it for cellular structures, functions, and so on. When water is lost in a river or polluted, life forms suffer and water loss would lead to a shortage of water and a shortage of life forms as they become extinct, and that would lead to a disruption in the ecosystem.
Hence, when people fail to conserve water, the following will occur: increased sewage system failures, as in Option A, because water conservation should be done in order to get an equal amount of water everywhere.

What is the mass of an atom with seven protons seven neutrons and eight electrons
Answers
Answer:
The atom is a nitrogen atom and the mass of the atom is 14.0067 u.
An atom with seven protons, seven neutrons, and eight electrons has a mass of 14 g.
What is an atom?Atoms are made up of protons, neutrons, and electrons. Each element has an atomic number that corresponds to the number of protons in its nucleus.
Given that,
Number of protons is 7.Number of neutrons is 7.Number of electrons is 8.The mass number of an atom is the sum of its atomic number and neutron number.
Mass number = number of neutron + atomic number
As the atomic number of an element will be equal to the number of protons of such elements, so in this case,
Mass number = 7 + 7Mass number = 14 gThus, the mass of an atom with seven protons, seven neutrons, and eight electrons is 14 g

What are Volcanoes?A volcano is an opening or rupture in the earth's surface which allows magma (hot liquid and semi-liquid rock), volcanic ash and gases to come out from there. When the tectonic plates come together or separate, they will occur. It can also occur in the middle of plates due to volcanic hotspots.
There are three types of Volcanoes-
Cinder Cone VolcanoesComposite Volcanoes (Stratovolcanoes)Shield Volcanoes1. Cinder Cone Volcanoes are the simplest type of volcano which occur when particles and blobs of lava are ejected from a volcanic vent.
2. Composite Volcanoes (Stratovolcanoes) have conduit system inside which channels magma from deep within the Earth to the surface.
3. Shield Volcanoes pours out of shield volcanoes is thin and it can travel for great distances down the shallow slopes of the volcano.
