Find the density of an 8 gram rock if the water in a graduated cylinder rises from 25.0 mL to
29.0 mL when the rock is placed in to the graduated cylinder.

Answers

To measure the density of the stone placed in a graduated cylinder let us follow these steps bellow

Measure the volume of water poured into a graduated cylinderPlace the object in the water and remeasure the volume. The difference between the two volume measurements is the volume of the object. Divide the mass by the volume to calculate the density of the object.

We know that the formula for density is given as

Given data

Mass = 8gram

Initial Volume of water in cylinder = 25mL

Final Volume of water in cylinder  = 29mL

Hence the volume of the rock  = 29-25 = 4mL

Therefore the density of the rock = 8/4 = 2 g/mL

calculate the molarity of a 50.0 ml of a 0.150 m hcl solution when 30.0 ml of water is added.

Answers

Answer:

0.09375 M

Explanation:

You want to use the following equation:

M1*V1=M2*V2

Then plug in the 50ml to V1 and 0.15M to M1 and 80ml to V2 (add the 50 and 30). The next thing you want to do is change the mL to liters, since Molarity is moles/liter. Once that is done, solve algebraically for answer.

** Also don't forget to capitalize the M when you mean Molarity, because it is different than m.**

A ball rolls down a hill. It starts with velocity of 2 ms. After 2 seconds, the ball has a velocity of 12 ms. What is the acceleration of the ball? 2 ms2 4 ms2 5 ms2 7 ms2

Answers

Answer:

5 ms2

Explanation:

The acceleration of the ball is 5 ms2.

What is acceleration?

Acceleration is the rate at which an object's velocity with respect to time changes. It is a vector quantity to accelerate (in that they have magnitude and direction). The direction of the net force acting on an object determines the direction of its acceleration.

The acceleration of the car in its present direction of motion is referred to as a linear acceleration (or tangential acceleration in circular motions), and the passengers on board feel a force pressing them back into their seats as a result.

The acceleration that is used to change direction is referred to as radial acceleration (or centripetal acceleration in circular travels), and the reaction that the passengers feel is a centrifugal force.

Therefore, The acceleration of the ball is 5 ms2.

New research shows that a red food colouring with an R value of 0.62 (when a particular solvent and temperature are used) could be dangerous to certain people. Samples of food colouring from two different red sweets were collected and the chromatogram bolow was produced. For each of the sweets, state and explain whether or not you would recommend that the sweets are taken off the market based on this research, ​

Answers

It is recommended only for the second type of candy to be taken off the market.

Based on the background information, if a candy shows a 0,62 Rf value in the chromatography it is considered potentially dangerous, and therefore it should be taken off the market.

The Rf value is calculated using the following formula:

Rf =  Total distance traveled by a component/ Total distance from the pencil line to the solvent front

Now, let's find out if any of the components has an Rf equal to 0,62.

Note: To determine the distances I measured the image using a ruler and you can do the same, this will not alter the results.

Sample 1Total distance traveled by the component: 6cmTotal distance: 7 cmRf : 6 cm/ 7 cm = 0.85

     2. Sample 2

Total distance traveled by the component: 4.34cmTotal distance: 7 cmRf : 4.34 cm/ 7 cm = 0.62

This means sample 2 has the 0.62 Rf value and therefore it needs to be taken off the market.

Consider the substances quartz (SiOs), gold (Au), and nitrogen gas (N2). If possible, use the terms
molecule and compound to describe each substance. If one or more of the substances cannot be
described by the terms molecule and compound, explain why not.

Answers

Answer:

Silicon Dioxide is a compound usually referred to as Quartz, it's a crystalline sort of material that is commonly found and used for equipment and furniture (like tables for example). Their molecular geometry is of tetrahedral shape (how their bonds look like and such)

Gold is an element that is a transitional metal that is quite malleable (able to hammer it to sheets) and is ductile (can be made into wires). As you probably have guessed, gold is used a lot for jewelry due to its lustrous appearance, and the fact that it can't corrode as well as its rarity. Due to it not being able to corrode, it's pretty useful in circuitry as it requires less management unlike elements with higher electrical conductivity like copper or silver. However gold is pretty costly so it's not often relied on for technology and mostly just used for show instead.

N2 or nitrogen gas, may seem like a compound for people new to chemistry but is actually just a diatomic molecule, meaning they are composed of only 2 atoms. So elements that are diatomic are commonly found with only 2 atoms (Oxygen gas for example, or Hydrogen gas) Nitrogen is part of the "magnificent seven" (the elements which are diatomic".  Nitrogen is essential for a lot of living things (aside from us), and since they are the most abundant material in our air (78% of air is Nitrogen), there's plenty of life growing.

Compound and elements are differ from each other. Silicon dioxide ( SiO₂ ) is compound , gold ( Au ) is  element and nitrogen gas ( N₂ ) is compound.

What is difference between molecule and elements ?

Elements are always made-up of only one type of atom. Molecule is made up of more than one type of atom. Silicon dioxide is a compound, which is crystalline in nature. Their molecular geometry is of tetrahedral shape.

Gold is an element that is a transitional metal that is quite malleable and is ductile.  Gold ( Au ) is used a lot for jewelry. Nitrogen gas is  compound . It is diatomic in nature, So elements that are diatomic are commonly found with only 2 atoms.

Hence, silicon dioxide is compound, gold is element, and nitrogen gas is also compound.

B. A solution may have more than one solute.
C. Not all solutions are liquid.
D. A solution is a homogeneous mixture of two or more substances.
E. The solute is the substance present in the largest quantity.

Answers

Answer:

B, D, C

Explanation:

the solution may have more than one solute, a solution is a homogenous mixture of 2 or more substances and not all solutions are liquid

A solution is formed by the mixture of substances dissolved in water. There may have more than one solute. Not all solutions are liquid but there exists solid solutions too. Hence, options A, B, C are correct.

What are solutions?

A solution is a combination of a solvent and a solid solute. The solute can be completely dissolved in the solvent and can have a partial solubility.

Water is a good solvent which dissolve majority of compounds. But there are other solvents too forming solution with suitable solutes. Solutions can be homogenous or heterogenous. Homogenous solutions are forming one phase and the solute particles are uniformly arranged.

Heterogeneous solutions are those where the solute particles are arranged in a non-uniformity and they form a different phase from the solvent.

There can be more than one solute in a solution provided that the solute can be of miscibility with each other.
