Answer:

1.76 g/mL

Explanation:

You need to find the volume.  You can do this by subtracting the volume of the water and the rock by the volume of the water.

72.7 mL  -  50 mL  =  22.7 mL

Now that you have volume, divide the mass by the volume to find the density.

39.943 g/22.7 mL = 1.76 g/mL

Answer:

1. A claim

2. B evidence

Answer:

The rapid motion and collisions of molecules with the walls of the container causes pressure (force on a unit area). Pressure is proportional to the number of molecular collisions and the force of the collisions in a particular area. The more collisions of gas molecules with the walls, the higher the pressure

Explanation:

Answer:

Explanation:

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

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

From the question

mass = 57.6 g

volume = 40.25 cm³

We have

[tex]density = \frac{57.6}{40.25} \\ = 1.431055900...[/tex]

We have the final answer as

Answer:

Over ninety percent of all the atoms in the Universe are hydrogen atoms.

Explanation:

Over ninety percent of all the atoms in the Universe are hydrogen atoms. By mass, hydrogen makes up about 75% of all matter in the Universe. Hydrogen atoms are also the smallest and lightest of all the atoms with only one electron and one proton in a common single hydrogen atom (called protium).

Answer:

The salinity would decrease, which can lead to a huge change in the ecosystem. The brine shrimp and flies may for off, because there isn't enough salt for them. This would cause the bird population to decrease, because they wouldn't have the shrimp and flies as a food source.

Answer:

The heating of the Earth's surface and atmosphere by the sun drives convection within the atmosphere and ocean. This convection produces winds and ocean currents. The greater the pressure differences between a low-pressure area and a high-pressure area, the stronger the winds. I hope this helps

The sun heats the air near the equator of the earth, it becomes less dense and rises upward. As warm air rises, it cools and gets less dense than the air around it.

Convection can be d defined as the transfer of heat from one place to another due to the movement of heat or fluid. Convective heat transfer involves the processes of conduction as well as advection.

Gases and liquids can not be good conductors of heat under normal conditions, but they can easily transfer heat.

Convection occurs through diffusion or advection but does not take place in solids, as there is no movement of its constituent particles happens. The diffusion of heat in solids is known as thermal conduction.

The heat transfer that occurs between a surface and a liquid that is in contact with the surface is convection heat transfer.  

The Sun provides the energy for the convection in the ocean and produces ocean currents. There are two kinds of ocean currents: one is surface currents and the other deep currents.

Answer:

The procedure is Filtration

Explanation:

Filtration is a process that is use to separate insoluble solid from liquid for example Salt and water.

This process uses filter paper which is placed inside a funnel and then placed inside a beaker.

The mixture of sand and water is poured into the the filter paper and water then drains out down to the funnel and the beaker.

The solid part remain at the filter paper and it is called the residue and the water is the filtrate.

Answer:

water

Explanation:

Because it does not have more than one component.

Purview is the word that best replaces reach without changing the meaning of the sentence. Therefore, the correct option is option B.

A sentence is indeed a collection of words used to express a thought. A sentence always begins with such a capital letter then concludes with a period, punctuation mark, and exclamation point. Ideal sentence construction has a verb and a subject. Declarative sentences make a declaration, express an opinion, or make an emotion known.

Declarative sentences have a period at the end. Questions are asked in sentences known as interrogatives. These phrases are followed by a question mark. This kind of phrase is used to give instructions or make a request. There is typically a period at the end, but occasionally there is also an exclamation point. Univocal means having only one possible meaning. Purview is the word that best replaces reach without changing the meaning of the sentence.

Therefore, the correct option is option B.

Answer:

92gm

Explanation:

Atomic mass of Mg=24g=1 mole of Mg

∴  24g =1 mole of Mg contain 6.022×10^23 atom 

∴  6gm contains 246.022×1023×6

                            =4×6.022×10^23 atoms

Now according to question, there are 6.022×1023 atoms of Na 

23gm of Na contains 6.022×10^23 atoms

∴6.022×4×10^23 atoms of Na weighs 23×6.022×10^23×4/6.022×10^23⇒92gm

Answer:

40 C atoms

Explanation:

Step 1: Write organic compound

10C₄H₁₀

We see here that in 1 mol of C₄H₁₀, we would have 4 atoms of C.

We are given that we have 10 moles of C₄H₁₀.

Therefore, we have 4 · 10 = 40 atoms C
