Answer:

Temperature

Explanation:

It's called temperature.

This is because, in any substance an increase in temperature means that the particles on the average will move with greater speeds, or that they have greater kinetic energy while a decrease in temperature means that the particles on the average will move with lesser speeds, or that they have lesser kinetic energy.

Answer:

Soap breaks up the oil into smaller drops, which can mix with the water.

Explanation:

This works because soap is made up of molecules with two different ends.

The soap molecules works as a surfactant for the water oil interphase. The hydrophobic head of the soap molecules trap the oil and dirt ad remove from the surface.

Surfactants are chemical substances used to reduce the interfacial tension between substance boundary. Soaps and detergents acts as surfactants which are used to remove the dirt and oil from material surface.

Soap has both polar and non-polar characteristics. The alkaline part  in the soap causes it to have a polar head, and because of the electric charge on this head, the soap is hydrophilic. A hydrophilic part of soap is drawn to water and will cling to it.

In this instance, the positive-charged hydrogen atoms of the water's hydrogen atoms match with the polar head of the soap molecule. The other part of soap is a fatty acid tail, which is hydrophobic and can bind with the oil and dirt. The trapped oil molecules are then be removed by water.

Answer:

helium

The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.

The correct answer is - Luster.

Explanation:

Luster is a property that explains how the light is reflected on the surface of a mineral. Luster can be categorized with the help of if an element or mineral is metallic or non-metallic.

Pyrite has a shiny, opaque metallic luster which is similar to other metals. There are different types of luster other than metallic also found like, silky, dusty, pearly, waxy, and a few more.

Answer:

B. Na

Explanation:

Once balanced you get 2Na + Cl₂ ⇒ 2NaCl. Sodium is the limiting reagent because it would produce the smallest amount of the product (NaCl)–while chlorine is the excess reagent. Based off of the Na in the balanced equation, it would produce 3 moles of NaCl, and for Cl₂ it would produce an excess of 6 moles of NaCl. [It'd be wise to utilize stoichiometric factors to get a good grasp of this]

The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.

Answer: B. To connect two electrodes

Explanation:

The salt bridge forms a connecting link between the two electrodes. The function of the salt bridge is not to supply electrons from one electrolyte to another but to maintain a constant balance of charge as the electrons move from one half of the cell to the another. The electrons from from negative electrode to positive electrode that is from anode to cathode.

Replacement  reaction.

Given

A chemical reaction

AB + C → CB + A

Required

reaction type

Solution

There are several types of reactions that can occur

synthesis: 2 elements combine to form a single product

polymerization: monomers combine to produce a polymer

decomposition: One compound breaks down into 2 components

oxidation : a change in oxidation number

replacement can be divided into 2

single replacement if one element replaces the other elements of a compound

double replacement if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds

AB + C → CB + A

If we look at this reaction, element C replaces element A to form a new compound CB. So it is single replacement. But this reaction can also be said to be an oxidation-reduction reaction because there is a change in oxidation number

element A undergoes a reduction reaction

element C undergoes an oxidation reaction

So types of redox reactions can be combination, decomposition, displacement, combustion, and disproportion.

We can no longer ignore the fact that the world's climate is becoming more unpredictable and more extreme. As water levels rise, the risk of flooding looms large. At the same time, periods of drought are becoming longer and more frequent. Yet, our most precious resource – our planet's biosphere – is not only under threat. It is also the source of many of our solutions. Green Climate Solutions is the Wageningen Environmental Research programme that applies our understanding of nature and natural processes to address the challenges of climate change.
