A hockey puck is hit with a large force. The puck moves at a high speed as it slides over the ice.

What happens according to Newton’s first law of motion?

A) The puck does not lose any speed because ice is a very slippery surface.

B) The puck gradually slows down because mass makes objects slow down.

C) The puck gradually slows down because friction would be acting on it.

D) The puck does not lose any speed because once an object starts moving, the force of friction would no longer apply to it.

I NEED HELP PLZZ THX &lt;3 Question 16A Hockey Puck Is Hit With A Large Force. The Puck Moves At A High

Answers

Answer 1

Answer:

C) The puck gradually slows down because friction would be acting on it.

Explanation:

It would be C because the puck would be scraping the ice and when it's scraping it slowly losses its speed because the ground is pushing it lightly

Sulfuric acid is an important chemical in industrial production of many products. In the “old” days, it was called oil of vitriol. It is commonly dyed brown now to alert people to its hazards because it is hugely corrosive. It is commonly found in car batteries. What is the molarity of 25.9 moles of sulfuric acid dissolved in 4.00 L of solution?

Answers

Answer:

6.475 M

Explanation:

Number of moles = 25.9 moles

Volume = 4.00 L

Molarity = ?

The relationship between the quantities is given as;

Molarity = Number of moles / Volume

Molarity = 25.9 / 4

Molarity = 6.475 M

3 gasses are mixed together (N2, O2, and He). The gauge of the N2 states a pressure of 1.23 atm. The gauge on the O2 tank shows 2.3 atm. The Helium gauge is broken. When the gasses are mixed, the total pressure of the tank is 6.50 atm. What is the pressure of the He?

a) 3.47 atm

b) 2.97 atm

c) 0.435 atm

d) 10.03 atm

Answers

Answer: The pressure of the He is 2.97 atm

Explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

[tex]p_{total}=p_{N_2}+p_{O_2}+p_{He}.[/tex]

Given : [tex]p_{total}[/tex] =total pressure of gases = 6.50 atm

[tex]p_{N_2}[/tex] = partial pressure of Nitrogen = 1.23 atm

[tex]p_{O_2}[/tex] = partial pressure of oxygen = 2.3 atm

[tex]p_{He}[/tex] = partial pressure of Helium = ?

putting in the values we get:

[tex]6.50atm=1.23atm+2.3atm+p_{He}[/tex]  

[tex]p_{He}=2.97atm[/tex]

The pressure of the He is 2.97 atm

To which of the three main chemical classes does Mercury (Hg) belong?
a) It's not an element in the periodic table
b) Metalloids
c) Non-metals
d) Metals

Answers

Answer:

Metals

Explanation:

It is a transition metal

The periodic table has a lot of different properties in how it is presented, one of these, is that the elements are separated in blocks by their properties.

From its position in the table, we can see that the correct option is d) metals.

The general way of knowing if an element is a metal or not, is to look if it is the D block in the periodic table.

This block contains all the transition metals (not all the metals) but every element in it is a metal. If we look for the mercury, we can see that it is in block D, just next to gold (Au).

Just from this, we can conclude that mercury is a metal, so the correct option is d.

Why can more sugar be dissolved in hot water than cold water (more solute be dissolved in hot solvent then cold solvent)

Answers

sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. when water is heated, the molecules gain energy and because of that, move faster. as they move faster, they come in contact with the sugar more often, causing it to dissolve faster.

(Help would be greatly appreciated, chemistry is not my strong suit) How many moles of NaCl are present in a solution with a molarity of 8.59M and 125mL of a solution?
1. 1.07g
2. 62.7mol
3. 1.07mol
4. 62.7g

Answers

Molarity is a unit of concentration defined as the number of moles of solute (the substance being dissolved) per volume of solution (the solvent in which all the solute is dissolved). Mathematically, molarity is expressed as

[tex]M = \frac{\text{ mol solute}}{\text{ L solution}}[/tex].

In this question, we are given the molarity and the volume of a solution of NaCl. We can use this information to calculate the number of moles of NaCl present in the solution. Rearranging the equation to solve for moles of solute, we multiply the molarity by the volume of the solution (the units for volume must be in liters, so 125 mL is expressed as the equivalent 0.125 L):

[tex](8.59 \text{ M})(0.125 \text{ L}) = 1.07 \text{ moles of NaCl}.[/tex]

The question asks for the number of moles of NaCl in this solution, so number 3 would be correct.

CI2

Answers

Answer: 1.12 Liters

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given molecules}}{\text {avogadro's number}}=\frac{3.24\times 10^{22}}{6.023\times 10^{23}}=0.05moles[/tex]

1 mol of [tex]Cl_2[/tex] occupy = 22.4 L

Thus 0.05 mol of [tex]Cl_2[/tex] will occupy = [tex]\frac{22.4}{1}\times 0.05=1.12 L[/tex]

The molar mass of two equally sized samples of unknown gaseous compounds is shown in the table. Molar Mass Comparison Gas Molar Mass A 17 g/mol B 36.5 g/mol Which statement describes the density and diffusion of both gases at STP? Gas A has a higher density and diffuses faster than Gas B. Gas A has a higher density and diffuses slower than Gas B. Gas A has a lower density and diffuses faster than Gas B Gas A has a lower density and diffuses slower than Gas B.

Answers

Answer:

Effusion  is the process of a gas being poured out through a hole diametrically smaller than the structural exit of the container.

A lighter gas effuses faster than a heavier gas.

Thus gas A has a lower density and effuses slower than Gas B.

Explanation:

The gas with a lower molar mass will have a lower density and diffuses at a slower rate. Thus gas A has a lower density than gas B and diffuses slower than gas B.

Three points should be noted here;

The density of any substance is related to the molar mass.[tex]D=M/V[/tex], where [tex]D[/tex] is the density, [tex]M[/tex] is the mass and [tex]V[/tex] is the volume of the substance.The density of the gas is directly proportional to the molar mass of the gas.

Hence the gas A has lower density and the gas B has higher density as the molar mass of A is [tex]17 g/mol[/tex] and of B is [tex]36.5 g/mol[/tex].

About Diffusion please note the below points;

Diffusion is the process of movement of a substance from the area of higher concentration to the area of lower concentration.The gas with a smaller mass will diffuse slower in rate than the gas with a higher mass.

Hence the gas A diffuses slower in rate than gas B.

Thus the correct answer is "Gas A has a lower density and diffuses slower than Gas B".
