O D. The ductility allows heat to move along an edge quickly.

Answer:

rainfall/water

Explanation:

The possession of drip tips by the leaves of plants in the rainforest is a form of adaptation against high rainfall. Without the drip tips on leaves, water will persist on the surface of leaves, and in conjunction with the warm climate, promotes the growth of pathogens such as fungi and bacteria.

Hence, the possession of drip tips on leaves is an indication of the prevalence of water in the rainforest region.

Answer:

Diagram B is a mixture of compounds

Explanation:

The false statement about any of the diagram is that diagram B is a mixture of compounds.

Diagram is not a mixture of compounds. It is a single compound in gaseous state .

3)6 electrons and neon

In an atom there are levels of energy in the shell and sub shell  

This energy level is expressed in the form of electron configurations.  

The electron configuration Oxygen (atomic number = 8) :

1s²2s²2p⁴

Oxygen will try to achieve stability (according to the octet rule) by binding 2 electrons so that the 2p orbits are filled with 6 electrons, so that the configuration is stable like the noble gases Neon

₁₀Ne = 1s² 2s² 2p⁶

The balanced equation :

2KOH+CO₂⇒K₂CO₃+H₂O

Equalization of chemical reaction equations can be done using variables. Steps in equalizing the reaction equation:

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c etc.

2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index between reactant and product

3. Select the coefficient of the substance with the most complex chemical formula equal to 1

Reaction

KOH+CO₂⇒K₂CO₃+H₂O

aKOH+bCO₂⇒K₂CO₃+cH₂O

K, left=a, right=2⇒a=2

H, left=a, right=2c⇒a=2c⇒2=2c⇒c=1

O, left=a+2b, right=3+c⇒a+2b=3+c⇒2+2b=3+1⇒2b=2⇒b=1

the equation becomes :

2KOH+CO₂⇒K₂CO₃+H₂O

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.

Answer:

Direct

Explanation:

Edge

When the temperature increases with an increase in pressure, it is a direct relationship.

Gay-Lussac's law can be described as when the volume of the gas remains constant then the pressure of a gas is directly proportional to the absolute temperature of the gas.

The mathematical equation of Gay Lussca's law is written as follows:

P/T = k

It can be represented as the pressure is directly proportional to the absolute temperature.

P ∝ T               (where 'V' volume of gas is constant)

or

[tex]\frac{P_1}{T_1} =\frac{P_2}{T_2}[/tex]

Where P₁ and T₁ are the initial temperature and pressure while P₂ and T₂ are the final pressure and temperature of the gas.

The sample of gas has a fixed volume of gas and on increasing the temperature the gas molecules acquire more and more kinetic energy. So the pressure of the gas will also increase.

Therefore, there will be a direct relationship between temperature and pressure of gas.

Answer:

Explanation:

The nucleus of an atom contains neutrons and protons bonded tightly together. The same chemical element can have a different number of neutrons and still be the same element.

Answer:

The particles move faster and are far apart

Explanation:

A substance may exist in three states of matter; solid, liquid and gas.

In the solid state, there is very strong intermolecular forces between the particles of the substance. They can only vibrate or rotate about their mean positions but can not translate.

In the liquid state, the particles of the substance have a greater degree of freedom than in the solid. The magnitude of intermolecular forces is lower than in solids, the molecules can move at low speeds.

In a gas, the molecules are separated from each other with negligible intermolecular interaction hence they move at very high speed.

Therefore, for the water gas particles in the air above the cup; the particles move faster and are far apart.

Answer:

six

Explanation:

Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.

Valence electrons are the electrons in the outermost shell of an atom.

Answer:

The flash of green light may give off some type of energy that only emits from green light which probably energizes the Flubber

Explanation:

A flubber is a rubber like polymer that absorbs and amplifies energy. A flubber absorbs energy from a light source and electrons present in it are excited in order to emit light of higher wavelength. The green light absorbed by the flubber to emit longer wavelength of light emitting more energy.

Answer:

preservation of raw materials

Explanation:

Reusing and recycling is the process by which the used products are used again or recycled in different form to use it again. Excessive use of the raw materials can lead to their extinction. Recycling the materials helps in decreasing the pollution in the environment. It also helps in reduction in the emission of the harmful gases. When municipal wastes are reused or recycled, the raw materials are preserved. These are the process involved in sustainable use of resources.

Answer:

0.272 mol AgOH

Explanation:

Figure out the amount of AgOH in mass, and to find the amount of moles–you just divide the given amount (34g) by the molar mass of AgOH (125g) to figure out the amount of moles. 34/125 = 0.272 mol AgOH.

Answer:
