Answer 1

Answer:

Matter can be classified according to physical and chemical properties. Matter is anything that occupies space and has mass. The three states of matter are solid, liquid, and gas. A physical change involves the conversion of a substance from one state of matter to another, without changing its chemical composition.

Please help! If a forensic chemist discovers evidence through examination which would prove a person guilty of a crime, why then might this person not be convicted?

Answers

Explanation: You cannot be convicted of a crime without evidence. You cannot be convicted of a state crime. You cannot be convicted of a federal crime. If there is no evidence against you, under the law, it simply is not possible for the prosecutor's office to obtain a conviction at trial. So, when you do have evidence it is really impossible to not get convicted unless the judge truly believes your side of the story and declares you not guilty.

Suppose 10 atoms of carbon (C) react with 20 atoms of oxygen (O). According to the Law of Conservation of Matter, how many atoms will there be in the product of this reaction?(1 point)
A) 20

B) 15

C) 10

D) 30

Answers

Answer:

D 30

Explanation:

whenever there is a reaction, the amount of atoms don't change, because matter can't be created or destroyed. Add the carbon and oxygen atoms together

According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.

LAW OF CONSERVATION OF MATTER:

The law of conservation of matter states that matter can neither be created nor produced in a chemical reaction.

This further means that the amount of matter in the reactant of a reaction must equate that of the products.

Hence, if 10 atoms of carbon (C) react with 20 atoms of oxygen (O), there will be 10 + 20 = 30 atoms of product in this reaction.

Therefore, According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.

What is the charge of a chromium ion that has lost 4 electrons?

Answers

Answer:

Explanation:

When an atom loses electron(s) it will lose some of its negative charge and so becomes positively charged. A positive ion is formed where an atom has more protons than electrons. In the opposite case when an atom gains electron(s) it becomes negatively charged (more electrons than protons)

and plzs do not hate

The charge of chromium after losing 4 electrons is +2.

What is the ionic charge?

Ions are two or more charged particles that make up ionic compounds. Electrostatic attraction keeps the ions together (in the solid phase) despite their opposing charges. Cations are positively charged ions, whereas anions are negatively charged ions. Many factors make ionic molecules significant.

They act as electrolytes for batteries and conduct electricity when dissolved in water. They could form a strong bond with other charged particles, such as those found in environmental samples or the human body. They find use in fireworks, flares, and lights because they are frequently multicolored when burned. The list is endless!

Studying the nomenclature used to give ionic compounds distinctive names is a good method to become familiar with and exposed to them. You will learn how to properly explain the identification of substances in language by converting from a chemical formula to a name—a highly essential problem as the diversity and complexity of known compounds keeps growing!

Therefore, the charge on chromium after losing 4 electrons is +2.

0.93 grams per milliliter

Explanation:

Density is the division of mass by volume. It is how "hefty" an object is; for example, wood isn't very "hefty" but metal is. The density is measured in mass over volume, so it is 9.3/10. After applying units, it is 0.93 grams per milliliter.

B. A physical change can separate its mixed components.
C. It is made up of millions of units of a single type of compound.
D. It is made up of millions of atoms of a single element

Answers

Answer:

B. A physical change can separate its mixed components.

Explanation:

Atoms and molecules of different elements can come together to form a substance known as MIXTURE. A mixture comprises of several units of different elements or compounds that are not chemically joined together. This is the case of hair gel, which is a mixture i.e. it contains several compounds mixed together in an uneven ratio.

Since the components of a mixture such as the hair gel, are not joined together chemically i.e no chemical bonding or altering of chemical structure occurs between the mixture constituents, they can be separated using physical means. Physical methods of separation such as boiling, chromatography, etc.

What is electrolysis?

Electrolysis is the process of conversion of electrical energy to chemical energy by applying an electric field. Electrolysis involves an electrolyte which can conduct by furnishing ions.

Generally electroanalytical cells involves two metallic electrodes which are immersed in a molten electrolyte containing the same metal ions.

When an electric current is passed through water, it will undergo electrolysis and produce hydrogen and oxygen in gaseous state. These gases bubbles out from the water and therefore, there occurs a mass loss for water.

Coyotes are multicellular organisms.

Trees are multicellular organisms. They are made up of eukaryotic cells, which are complex cells full of organelles.

Coyotes and oak trees are not unicellular organisms but are multicellular organisms.

Unicellular organisms are living organisms that consist of only one cell. These organisms are complete and functional in their single-cell structure, carrying out all essential life processes, such as respiration, nutrition, reproduction, and growth, within that one cell. Examples of unicellular organisms include bacteria, archaea, protozoa, certain algae, and some fungi.

Coyotes and oak trees are multicellular organisms made up of many cells. Coyotes are mammals, and oak trees are plants, both of which are complex organisms with specialized tissues and organs.

Include evidence from the article to support your answer. Do you think this author has an agenda? If so, what is it? If not, what is the purpose of her article? Does she achieve her purpose? Whats for Lunch?Marcia Amidon LustedZachary Maxwell was tired of trying to explain to his parents why he wanted to bring lunch to school instead of eating hot lunch. They couldnt understand why he didnt want to eat the gourmet food described on the schools online menu, which sounded both nutritious and interesting. Zachary just couldnt convince them that the food wasnt as great as it sounded. So in the fall of 2011, he began sneaking a small video camera into the cafeteria at his school, to show his parents what the lunches were really like. Six months and 75 school lunches later, Zachary made a documentary film about his lunch called Yuck: A 4th Graders Short Documentary About School Lunch.Truth in Advertising?"The citys Department of Education says that its committed to providing delicious and nutritious meals through their food service program. But the lunch being served at my school was nothing like what they were advertising on their web site," Zachary, now 11, says in the documentarys trailer. "I told [my parents] thats not what they were actually serving me," he said. "But I dont think they believed me." For example, an "oven-baked pizza bagel with tricolor salad" was really nothing more than a slice of pizza and a wisp of lettuce. Sometimes there was no connection between the menu and what Zachary actually got. "Cheesy lasagna rolls with tomato basil sauce, roasted spinach with garlic and herbs" was, in reality, just a plastic-wrapped grilled cheese sandwich, all alone on a foam plate."When I came back home and showed them the footage, they were like, ugh!" Zachary said. His dad, an amateur filmmaker, started helping Zachary transform his video footage into a film. It won several awards, and Zachary also made appearances on television shows like Good Morning America.Not Perfect, But BetterLets face it: many times school lunches just arent going to taste as good as they sound. Students also complain that with lunches that follow the new school lunch guidelines, there just isnt enough food. Smaller portions, more fruits and veggies, and fewer calories leave some kids, especially teenagers, still hungry after eating their lunch. A group of students in Kansas even wrote a music video called "We Are Hungry," where they sing about their stomachs growling after lunch and how theyre collapsing on the sports field because they havent eaten enough.However, the new federal lunch guidelines do mandate meals that are better for students, with less sodium, more whole grains, fewer calories, and more fruits and vegetables, as well as skim or 1 percent milk. These are a definite improvement over school lunches of not that many years ago, which once stuck with fare like burgers, French fries, and chicken nuggets. Some schools even allowed fast food outlets like McDonalds and Pizza Hut to operate mini-restaurants in their cafeterias, or supply their products for students. Many schools have also reconsidered vending machines filled with sugary sodas, candy, and chips, replacing them with water and healthy snacks.The Lunch ForecastThe new school lunches are designed to help students eat better, and combat health problems like obesity in kids. Ideally, a healthy school lunch should also taste good ... or at least as good as the description on the menu. It should also keep students from taking a trip to the vending machine or a nearby convenience store as soon as lunch is over, because theyre still hungry. But will the lunches served in your cafeteria ever taste as good as a fast food burger or a gourmet meal cooked at home? You be the judge.
