Answer:

A. A. it will shrink.

A. slow down .

Explanation:

Hello there!

In this case, according to the gas laws, it is possible to answer to this questions:

1. Here, it is required to study a volume-temperature relationship by means of the Charles' law which states that the volume decreases as temperature does; for that reason, when dunking  the balloon into the cold water, one can notice A. it will shrink.

2. Here, according to the kinetic molecular theory, which states that higher temperatures provide higher amounts of energy to the molecules to move faster as they gain thermal energy; it is possible to infer that when a sample of gas is cooled, the particles of A. slow down  as they lose thermal energy.

Best regards!

I think its A. Low pressure indicates rising air, Which allows clouds to from.

Answer: c6h12o6+6o2→6co2+6h2o= C6H12O6 + 6O2 -> 6CO2 + 6H2O Yields 2755 kJ/mole of glucose. The reverse of this reaction – combing carbon dioxide and water to make sugar is known as photosynthesis. Photosynthesis is the process responsible for storing all the energy we extract from fossil fuels, crops, and all of our food. We will also see that it is part of a globally important cycle affected by our consumption of fossil fuels. Photosynthesis How is photosynthesis able to run the reaction above in the reverse direction? Somehow it must come up with 2755 kJ of energy to make each mole of glucose. Where does that energy come from? The short answer: photons of sunlight. The long answer: When the pigment chlorophyll inside the chloroplasts of a photosynthetic organism (phytoplankton, trees, other plants) absorbs sunlight, it becomes energetically ‘excited’ and grabs the hydrogen atoms away from a water molecule, leaving the oxygen atoms to escape as O2 gas. This is called ‘splitting water.’ The hydrogen atoms are then split into their component protons and electrons. The electrons are used to reduce carbon dioxide, in a series of many steps requiring more absorption of sunlight by chlorophyll, to glucose. When carbon dioxide receives those electrons, the extra negative charge attracts protons from elsewhere, creating hydrogen atoms attached to the carbon atom. This process is called reduction. When those reduced carbon dioxide molecules are combined together in a larger molecule, the result is glucose. This ‘combing together’ of small molecules requires an input of energy, which is provided by the ATP molecules made by the protons diffusing through the membrane of the chloroplast. The ATP molecule is simply a molecule that biology uses to store energy for later use. In this case, the mechanical energy created by the protons diffusing across the membrane turns a sort of molecular turbine that smashes together its precursors.

Answer:

One mole of CO2 has mass of 44 g and 32 g of O2. So 16 g of O2 have 22 g of CO2 or 0.5 moles of it.

The molecular formula for Nickel (IV) Chloride will be NiCl₂. Nickel reacts with chloride to form a salt. The salt is yellow in color and anhydrous.

A molecular formula is a way of presentation of chemical formula of a compound. It gives the information related to the type of atoms, number of atoms which constitutes the compound and the chemical properties.

Molecular formula of a chemical compound can be derived by the valency of element. In this question, molecular formula of the compound can be derived by:

Valency of Nickel = 2

Valency of Chlorine = 1

By the cross-multiplication of valency:

element 1(valency of element 2). element 2 (valency of element 1)

= Ni (1). Cl(2)

= NiCl₂

Therefore, the molecular formula of Nickel (IV) chloride will be NiCl₂.

Explanation:

metallic bonds occur among the metal atoms where iconic bonds join metal and nonmetals metallic bonding joins a bolt of metal atoms a sheet of aluminum foil and a copper wire are both place where you can see metallic bonding in action the Sea of electrons that is free to flow about the crystal of positive metal ions

Metallic bonding occurs between metal atoms. Among the given copper is example of metal in which copper atoms are strongly held by metallic bonds.

Metals are electropositive elements. Metals contains a pool of mobile electrons among the sea of positive ions. Metals exhibit some peculiar features such as conductivity, hardness, malleability, ductility, luster etc.

Metals atoms form well orders crystalline structure in which particles are held together by strong metallic bonds. In periodic table, the first two groups and all the d-block elements are metals.

Copper is a transition metal in d-block. Copper is a very important metal in our lives and in industries since it is used in constructions, electronics, house hold items etc., because of its hardness and conductivity. Hence, option 2 is correct.

The pairs of chemical elements that will combine to produce a covalent bond is: 1. Hydrogen and chlorine.

In Chemistry, the three (3) main types of chemical bonds include:

A covalent bond can be defined as a type of bond that typically involves the sharing of electrons between the atoms of a chemical element.

For example, the type of bond that is produced (formed) between hydrogen atoms and a chlorine atom is a covalent bond.

The hydrogen atom shares it single electron with a chlorine atom that is having seven (7) valence electrons to produce an inert gas such as hydrochloric acid (HCL).

In conclusion, the pairs of chemical elements that will combine to produce a covalent bond is hydrogen and chlorine.

Explanation:

Crystallography. an arrangement in space of isolated points (lattice points ) in a regular pattern, showing the positions of atoms, molecules, or ions in the structure of a crystal.

If an atom experiences sufficient thermal activation, it can move to a neighboring lattice position.4 If the vibration frequency of the atom is v and the atom has Z nearest neighbors, the total number of jump attempts is vZ. However, only a small fraction of the attempts will be successful, with a probability depending on the ratio between the necessary activation energy for a single jump QD and the thermal activation kBT. The effective jump frequency ΓD is then

(5.6)

With each successful jump, the atom travels one atomic distance λ and the total traveling distance in unit time is thus ΓDλ. Substituting the jump frequency ΓD into the expression for the root mean square displacement of a random walker [equation (5.5)] and using the spatial coordinate r leads to
