Question options:

less/slower


less/faster


more/slower

Answers

Answer:

More and Faster

Particles in a warmer block will have more kinetic energy and move faster than the particles in the colder block.

What is kinetic energy?

Kinetic energy is defined as a form of energy that an object or particle has by the reason of its movement.

It is also defined as the measure of the work that an object does by the virtue of its motion.

Kinetic energy can be expressed as

KE = 1/2mv²

Kinetic energy is produced when potential energy is released, triggered into motion by gravity, or chemical reaction among other crystals.

Thus, particles in a warmer block will have more kinetic energy and move faster than the particles in the colder block.

A system initially has a pressure of 12 atm and a volume of 9 L. What is the volume if the pressure is decreased to 6 atm?

Answers

Answer:

The answer is 18 L

Explanation:

In order to find the volume , we use the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we are finding the final volume

[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]

From the question

P1 = 12 atm

V1 = 9 L

P2 = 6 atm

We have

[tex]V_2 = \frac{12 \times 9}{6} = \frac{108}{6} \\ [/tex]

We have the final answer as

18 L

An example of the buoyant force on a piece of bread is the piece of bread floats on the surface of body water such as a lake.

What is the buoyant force?

This is a force experienced by objects when they are in a body of water. This force implies objects have an upward force, which in many cases causes them to float.

What are some examples of this force?

Any object that is submerged in water but floats or shows to have an upward force is an example of this force. Based on this, the option that clearly shows the buoyant force is a bread floating on a lake.

Answers

The formatting of the question is a bit scrambled: I'm not sure if there are separate steps that have been unintentionally consolidated into a seemingly discrete step, nor am I sure which letters actually correspond with which step(s). So, for clarity's sake, I treated every sentence as its own step and arranged all of them accordingly. Hopefully, you can then reorganize them according to the labeled steps as you have been provided.

Suspend a separatory funnel using an iron ring and ring stand. Make sure the stopcock is closed. Transfer the organic (dichloromethane) layer to the funnel. Add an equivalent volume of aqueous acid to the dichloromethane layer in the separatory funnel. Cap the separatory funnel with a glass or Teflon stopper. Remove the funnel from the iron ring and shake vigorously to mix the layers, periodically venting to release pressure.  Place the separatory funnel back in the Iron ring. Allow the layers to physically separate in the funnel. Remove the cap.Drain the bottom layer into a labeled beaker. Label the beaker "Organic Layer". Drain the remaining liquid into a labeled beaker.  Label this beaker "Aqueous Layer". Transfer the "Organic Layer" back to the empty separatory funnel. Repeat all steps.

Notes:

The letters have been replaced with numbers only to clarify the order of the steps. No changes were made to the steps themselves, including any stylistic errors.A very few set of sequential steps might be interchangeable, but the steps as separated and organized above is in accordance with standard liquid-liquid extraction protocol.Determining which layers are the "organic" and "aqueous" layers (i.e., whether the organic/aqueous layer, or vice-versa, is on the bottom/top ) is a nontrivial step; for this reason, when actually doing such extractions, the beakers (or whatever vessel) into which the layers are drained at any step are sometimes labeled "top layer" and "bottom layer" in case you misidentify which layers are, in fact, the organic and aqueous layers. Oftentimes, the organic layer is on top of the aqueous layer as many common organic solvents are less dense than water. Halogenated organic solvents, like dichloromethane, are one of the exceptions, and so will generally comprise the bottom layer.

What is the end
result of a chemical reaction?

Answers

Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.

The end of a chemical reaction is the product.

What is a chemical reaction?

A chemical reaction contains a reactant that reacts to form products. The reactant can be more than two, and the product can be two or more.

Food spoiling is a chemical reaction because it has an unpleasant odor, taste, and color change. Fruits undergo a chemical shift as they ripen. For instance, both the texture and color may change.

When we balance a chemical process, the number of moles or atoms on the left must match the amount on the right. Thus, the atoms participating in such a chemical process are discovered to have mass.

Chemical elements are uncontaminated by impurities or other elements and are pure substances made up of just one type of atom. They are found in the crust of the earth. Carbon, hydrogen, and oxygen are some examples.

Therefore, the end is the product.

Answers

Answer:

Empirical formula is Cr₂O₃.

Explanation:

Given data:

Percentage of Cr = 68.4%

Percentage of O = 31.6%

Empirical formula = ?

Solution:

Number of gram atoms of Cr = 68.4 / 52 = 1.3 2

Number of gram atoms of O = 31.6 / 16 = 1.98

Atomic ratio:

                            Cr               :         O

                           1.32/1.32     :       1.98/1.32

Which statement best describes the nuclear model of the atom. A) negative charges dispersed in a positively charged cloud B) positive charges dispersed in a negatively charged cloud C) small, dense positive nucleus surrounded by a diffuse negatively charged cloud D) small, dense negative nucleus surrounded by a diffuse positively charged cloud

Answers

Answer:

D.) small, dense negative nucleus surrounded by a diffuse positively charged cloud

Explanation:

I am not 100% sure but the reason I think this is the answer is because Protons and Neutrons are in the nucleus. Protons being positively charged and neutrons being negatively charged. Again, I do not know for sure, but I think D is the answer.

The statement that best describes the nuclear model of the atom is C) small, dense positive nucleus surrounded by a diffuse negatively charged cloud.

The atom is made up of 3 kinds of particles: protons, neutrons and electrons.

Protons (positive charge) and neutrons (zero charge) are in the nucleus, which concentrates 99% of the mass of the atom in 1% of the space. This is why is it positive and very dense.

Electrons (negative charges) are orbiting the nucleus in diffuse negatively charged clouds known as orbitals.

How many moles of Nitrogen in 40.0 g of N2O?
.14 g
25.5 g
14.5 g

Answers

Answer:

To do this question. we first have to find the mass% of nitrogen in N2O and then, using that percentage, we can simply find the number of moles of N from the number of moles of N2O

Mass % of Nitrogen:

Mass% of nitrogen = (Molar mass of N2 / Molar mass of N2O)*100

Mass% nitrogen = (28 / 44)*100

Mass% of Nitrogen = 0.63 * 100

Mass% nitrogen = 63%

Mass of Nitrogen:

So, now we can say that in any given mass of N2O. 63% of the total mass is the mass of Nitrogen

Hence, total mass * 63/100 = Mass of Nitrogen

Replacing the variables

40 * 0.63 = Mass of Nitrogen

Mass of Nitrogen = 25.2 grams
