3. A gold ring has a mass of 67.0 grams. When
placed in a graduated cylinder containing 10 ml of
water, the water rises to 13.47 ml. Calculate the
density of the ring.
I

Answers

Answer 1

Answer:

The answer is

19.3 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]Density = \frac{mass}{volume} [/tex]

From the question

mass = 67 g

Volume of ring = new volume of water - original volume of water

Volume = 13.47 - 10 = 3.47 mL

Substitute the values into the above formula and solve

That's

[tex]Density = \frac{67}{3.47} \\ = 19.308357[/tex]

We have the final answer as

19.3 g/mL

What must occur in order for a chemical reaction to be specifically classified as endothermic instead of
exothermic?

Atoms are rearranged.

Chemical bonds are formed.

Energy is released in the form of heat.

Energy is absorbed in the form of heat.

Answers

Answer:

A

Explanation:

What must happen in order for a chemical reaction to be specifically classified as endothermic instead of exothermic is that energy is absorbed in the form of heat.

Chemical reactions can be exothermic or endothermic depending on whether it gives off or absorb energy (in the form of heat).

When energy is given off by a reaction, the temperature of the reaction vessel becomes warmer than the initial temperature before the reaction. Such a reaction is said to be exothermic.

For endothermic reactions, heat energy is absorbed from the surrounding. Thus, the reaction vessel appears colder when compared to the initial temperature before the reaction.

MACROMOLECULES:

Macromolecules are large or complex molecules made up of monomers. The macromolecules in nature are as follows: proteins, carbohydrates, lipids and nucleic acids.

Each macromolecule performs specific functions in the body and hence, are very important.

Carbohydrates and lipids are used as energy storage, however, lipids store energy in the body for a long term than carbohydrates.

Carbohydrates store energy for a short term because they are readily used by the body.

Therefore, both macromolecules are used for energy storage, but only carbohydrates are used for short-term energy storage.

The answer is

0.32 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} [/tex]

From the question

mass = 6.05 g

volume = 19 mL

The density of the substance is

water is 11.19% hydrogen and 88.1% oxygen by mass. Lake superior contains about 1.2x10 kg of water. what mass of hydrogen is contained in lake superior

Answers

Answer:

mass of hydrogen in lake = 11.19% of 12

                                          = 1.3428

check if question is correct or not

Explanation:

Water is 11.19% hydrogen and 88.1% oxygen by mass. Lake superior contains about 1.2x10 kg of water the mass of hydrogen is 1.32 kg

What is mass?

Mass is defined as a unit of measurement that describes the amount of matter that makeup an object.

It can also be defined as quantitative measures of inertia, fundamental properties of all matter. It is a dimensionless quantity.

As given 11.19% hydrogen is present in 1.2 x 10 kg

So, the mass of hydrogen = 11.198 % of 1.2 x 10 kg

                                           = 11.19 / 100 x 12

                                           = 1.32 kg

Thus, water is 11.19% hydrogen and 88.1% oxygen by mass. Lake superior contains about 1.2x10 kg of water the mass of hydrogen is 1.32 kg.

Molding a shape from soft, malleable material (clay or plaster) or constructing a shape from harder material (such as metal or paper). Molding is what a child does with Play-Doh or origami.

Answers

Complete question is;

Molding a shape from soft, malleable material (clay or plaster) or constructing a shape from harder material (such as metal or paper) is called what?

Molding is what a child does with Play-Doh or origami

Answer:

Modeling

Explanation:

In chemistry, we have a branch called modeling chemistry. In modeling, we organize together a series of models instead of a collection of topics. In this approach, we will begin with a phenomena that can be readily observed and are gradually develop the simplest model of matter that helps us make sense of our observations.

Now in the question, we are Molding a shape from soft, malleable materials like clay/plaster or constructing from harder materials like metal/paper. This means that we are organizing a series of models from either soft & malleable or harder materials to produce a simple model shape.

Thus, this is simply modeling.

What happens when a Bose-Einstein condensate forms?
A. A large atom is split into many smaller atoms temporarily.
B. The atoms of the solid condense into one large superatom.
C. It causes all matter touching it to condense into a liquid.
D. The electrons separate from the nuclei forming a mass of unbound positive and negative charges.

Answers

Answer:

the answer would be B

Explanation:

The atoms of the solid condense into one large superatom. Hence, option B is correct.

What are atoms?

An atom contains a central nucleus surrounded by one or more electrons.

Bose-Einstein condensation occurs at a temperature very close to absolute zero i.e 273.15 degrees centigrade. Under such conditions, a large quantity of Boson occupies the lowest quantum state, at which point microscopic quantum phenomena become apparent macroscopically.  A BEC is formed by cooling a gas of extremely low density about one hundred thousandth the density of normal air, to ultra-low temperature.

Hence, option B is correct.

Answer:

Explanation:

took the test

Water exhibits strong adhesion and cohesion, which allows capillary action to occur.

What property of water allows it to move through a plant?

The cohesive properties of water (hydrogen bonding between adjacent water molecules) allow the column of water to be 'pulled' up through the plant as water molecules are evaporating at the surfaces of leaf cells. This process has been termed the Cohesion Theory of Sap Ascent in plants.

What are adhesion and cohesion?

Cohesion and adhesion are two water properties that describe how water molecules interact with each other. and how water molecules interact with other things like leaves or even you. Cohesion means that water likes to stick to itself and adhesion means that water likes to stick to other things.
