Calculate The Number Of Sucrose Molecules In A 75.0 Gram Sample.

Answers

Answer 1

Answer:

1.32*10^23 molecules

Explanation:

sucrose formula: C12H22O11

molar mass: 12(12.01)+22(1.01)+11(16.00)=342.34g/mol

75.0 g C12H22O11 * (1 mol C12H22O11)/(342.34g C12H22O11)=0.219 mol C12H22O11

0.219 mol * (6.022*10^23)/mol = 1.32*10^23 molecules (three sig. figures)

A 13.9 - g piece of metal ( specific heat capacity is 0.449 /g^ C)who whose temperature is 54.2 degrees * C was added to a sample of water at 13.4 degrees * C in a constant - pressure calorimeter of negligible heat capacity . If the final temperature of the water is 15.6 °C, calculate the mass of the water in the calorimeter .​

Answers

Answer:

26.2g = Mass of water in the calorimeter

Explanation:

The heat absorbed for the water is equal to the heat released for the metal. Based on the equation:

Q = m*C*ΔT

Where Q is heat, m is the mass of the sample, C is specific heat of the material and ΔT is change in temperature

Replacing we can write:

[tex]m_{metal}*C_{metal}*dT_{metal}=m_{water}*C_{water}*dT_{water}[/tex]

13.9g * 0.449J/g°C * (54.2°C-15.6°C) = m(H₂O) * 4.184J/g°C * (15.6°C-13.4°C)

240.9J = m(H₂O) * 9.2J/g

26.2g = Mass of water in the calorimeter

what do igneous rocks become when they break down and settle into layers?

Answers

Answer:

Sedimentary rocks

Explanation:

Igneous rocks will become sedimentary rocks when they break down and settle into layers .

Igneous rocks are rocks that are formed by the cooling and solidification of magma within or on the earth crust.

When agents of weathering and denudation forces acts on a rock body, they break them down producing sediments in the process.

Sediments are transported into depositional basins where they are laid down and cemented together. This in turn forms sedimentary rocks. The break down and settling of sediments leads to the formation of sedimentary rocks.

A. It disrupts the balance between predators and prey
B. It decreases the amount of producers
C. It directly increases the population of decomposers
D. It decreases competition for food among carnivores

Answers

Answer:

A. It disrupts the balance between predators and prey

Explanation:

The effect on the ecosystem when populations of white  - tailed deer are overhunted is that it disrupts the balance between predators and prey within the ecosystem.

The whited - tailed deer is the usually the prey. The carnivores are the cats and other flesh eating animals. When the deer is over-hunted, there are more predators compared to prey. This leads to a serious imbalance and a high level of competition for the scarce prey.

For species that reproduce asexually, all their offspring are
A. genetically identical
B. genetically different
C. almost identical
D. slightly different​

Answers

Answer:

A. genetically identical

Explanation:

Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. A single individual can produce offspring asexually and large numbers of offspring can be produced quickly

All the offspring that are produced in the process are genetically identical.

When we talk about this mode of reproduction, we talk about a mode of reproduction in which an organism reproduces without the fusion of gametes. This occurs essentially by cell division.

When this occur, there is no crossing of genetic material as such, all the offspring that are produced in the process are genetically identical.

The unknown alcohol

Solution

Density of sample :

= 39.4 g : 50 ml

= 0.788 g/ml

The unknown alcohol at room temperature = liquid, so the unknown alcohol is 2-propanol because it has temperature range between -90 to 82 for liquid and the density = 0.788 g/ml

Osmium metal, the densest element, has a density of 22.6 g/mL, while hydrogen, the least dense element, has a density of 8.99 e-5 g/mL. Calculate the volume occupied by 1.00 g of each element. How many times more dense is osmium than hydrogen?

Answers

Answer:

1. Volume of osmium = 0.044 mL

2. Volume of Hydrogen = 11123.47 mL

3. Osmium is 251390 times denser than hydrogen

Explanation:

From the question given above, the following data were obtained:

Density of osmium = 22.6 g/mL

Density of Hydrogen = 8.99×10¯⁵ g/mL

Mass of osmium = 1 g

Mass of Hydrogen = 1 g

1. Determination of the Volume of osmium.

Density of osmium = 22.6 g/mL

Mass of osmium = 1 g

Volume of osmium =?

Density = mass /volume

22.6 = 1 / volume

Cross multiply

22.6 × volume = 1

Divide both side by 22.6

Volume = 1 / 22.6

Volume of osmium = 0.044 mL

2. Determination of the Volume of Hydrogen.

Density of osmium = 8.99×10¯⁵ g/mL

Mass of osmium = 1 g

Volume of osmium =?

Density = mass /volume

8.99×10¯⁵ = 1 / volume

Cross multiply

8.99×10¯⁵ × volume = 1

Divide both side by 8.99×10¯⁵

Volume = 1 / 8.99×10¯⁵

Volume of Hydrogen = 11123.47 mL

3. Determination of the number of times osmium is denser than hydrogen.

Density of osmium (Dₒ) = 22.6 g/mL

Density of Hydrogen (Dₕ) = 8.99×10¯⁵ g/mL

Dₒ / Dₕ = 22.6 / 8.99×10¯⁵

Dₒ / Dₕ = 251390

Cross multiply

Dₒ = 251390 × Dₕ

Thus, osmium is 251390 times denser than hydrogen.

Calculate the volume, at STP, of a 0.950 g sample of Carbon Monoxide gas, CO.

Answers

Answer:

0.76L is the pressure of CO at STP

Explanation:

To solve this question we must use combined gas law:

PV = nRT

Where P is the pressure of the gas (1atm at STP)

V is volume (Our incognite)

n are moles of the gas (0.950g * (1mol/28g) = 0.034 moles

R is gas constant (0.082atmL/molK)

T is absolute temperature (273.15K at STP)

V = nRT/P

V = 0.034mol*0.082atmL/molK*273.15K / 1atm

V = 0.76L is the pressure of CO at STP
