What is the mass of 42.0 mL of a liquid with a density of 1.65 g/mL?

Answers

Answer 1

Answer:

The answer is

69.30 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume = 42 mL

density = 1.65 g/mL

The mass is

mass = 1.65 × 42

We have the final answer as

69.3 g

Potassium/Atomic number

This tells you that potassium has 19 protons and - since the number of protons is the same as the number of electrons- also 19 electrons. To find out the number of neutrons you have to look at the atomic mass or weight of the element. This can also be found in the periodic table.

29.4 mL of an CH3COOH solution were titrated with 18.5 mL of a 0.0175 m LiOH solution to reach the equivalence point. What is the molarity of the CH3COOH solution

Answers

Answer:

0.11 M

Explanation:

The computation of molarity of the CH3COOH solution is shown below:-

[tex]M_2 = \frac{M_1V_1}{V_2}[/tex]

Where,

[tex]M_1[/tex] = Molarity of LioH = 0.0175

[tex]V_1[/tex] = Volume of LioH = 18.5 ml

[tex]V_2[/tex] = Volume of CH3COOH = 29.4 ml

Now, we will put the values into the formula

[tex]= \frac{0.0175\times 18.5}{29.4}\\\\ = \frac{0.32375}{29.4}[/tex]

Which gives result

= 0.011 M

Therefore for computing the molarity of the CH3COOH solution we simply applied the above formula.

Which substance is composed of only one type of atom? A: water B: sugar C: salt D: gold

Answers

Answer:

Gold

Explanation:

water = H2O(3 atoms)

Sugar = C12H22O11 (45 atoms)

Salt = NaCl ( 2 atoms)

Gold = Au ( 1 atom)

A substance that is composed of only one type of atom is gold. Thus, the correct option for this question is D.

What is an atom?

An atom may be defined as the smallest unit of any matter that has the ability to form a chemical element. An atom may also be characterized as a particle of matter that uniquely illustrates a chemical element.

Water is composed of two atoms which are hydrogen and oxygen. Its chemical formula is [tex]H_20.[/tex] Sugar is a complex compound that consists of atoms of Carbon, hydrogen, and oxygen. Its chemical formula is [tex]C_6H_1_2O_6.[/tex] Salt typically consists of atoms of sodium and chlorine. Its chemical formula is NaCl.

Therefore, gold is a substance that is composed of only one type of atom. Thus, the correct option for this question is D.

The forces between water molecules are stronger than the forces between ethanol molecules. Which liquid would probably be most difficult for an insect to walk on?

Answers

An insect would have a harder time walking on ethanol than it would water. Water has stronger intermolecular forces which leads to higher surface tension. The higher surface tension allows for the insect to be easily supported

Answer:
An insect would have an easier time walking on the surface of water than on the surface of ethanol.
Water’s stronger intermolecular forces lead to higher surface tension.
Higher surface tension allows water to support the insect.

tony ate 3/4 of the pizza. mike ate 7/16 of the pizza. how much more did tony eat than mike

Answers

Answer:

3/4 needs to be times by 4

so it's

12/16 then you minus 7/16

the answer is

5/16

Answer: 5/16

Explanation:

Multiply tonys 3/4 by 4 in order to get the same denominator as mike's 7/16. You should get 12/16 since 4x3=12, and now you can subtract the smaller fraction 7/16 from the bigger one 12/16, you should get a difference of 5/16.

If one end of an iron bar is heated, what causes thermal energy to transfer to the other end? a radiation b conduction c heat of fusion d convection

Answers

Answer:

Option B:

Conduction

Explanation:

Conduction is the transfer of heat from one molecule to another between two solids that are in direct contact with each other. For the conduction of heat to occur, the medium involved must be solid. This is because the molecules of solids are closely packed together and they cannot freely move about. The heat flowing through them can easily be passed on from one molecule to the other until it reaches all the parts of the object. This is exactly what will happen to the iron bar. Thermal energy from one end of the bar will get transferred between the molecules of the iron bar until it reaches the other end.

Convection on the other hand involves the transfer of heat through a liquid medium.

Radiation involves teh transfer of heat in a vacuum.

Answer:

b) conduction

In a heterogeneous mixture, the different components can be easily distinguished and separated. The composition and properties of the mixture can vary at different locations within the mixture.

In a heterogeneous mixture, the substances do not blend together at the molecular level, unlike in a homogeneous mixture where the components are uniformly distributed.

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.
