what mining biodivirsity​

Answers

Answer 1

Answer:

how many atoms are there in 8.08 moles of carbon dioxide

Answers

Answer:

145.97×10²³ atoms

Explanation:

Given data:

Number of moles of CO₂ = 8.08 mol

Number of atoms of CO₂ = ?

Solution:

1 mole of CO₂ contain 1 mole C atom.

8.08 mole contain 8.08× 1 = 8.08 mole of C atom.

1 mole of CO₂ contain 2 moles of O atom.

8.08mole contain 8.08×2 = 16.16 mole of O atom.

Total number of moles of atoms = 8.08 mole + 16.16 mole

Total number of moles of atoms = 24.24 mol

Number of atoms of CO₂:

1 mole of any substance contain 6.022×10²³ atoms.

24.24 mol ×6.022×10²³ atoms / 1 mol

145.97×10²³ atoms

Consider the reaction
H,01) +energy > H2(g) +%02(g)
Which of the following phrases best describes this reaction?
A Endothermic, absorbing energy
B) Endothermic, releasing energy
C) Exothermic, absorbing energy
D) Exothermic, releasing energy

Answers

The following phrases best describe this reaction : A Endothermic, absorbing energy

Further explanation

Delta H reaction (ΔH) is the amount of heat change between the system and its environment  

(ΔH) can be positive (endothermic = requires heat) or negative (exothermic = releasing heat)  

∆H positive (endothermic): energy (heat) is absorbed from the environment to the system

∆H negative (exothermic): energy (heat) released from the system to the environment

Reaction

H₂O(g) + energy ⇒ H₂(g) + 1/2O₂(g)

In this reaction, it is shown that to break the bonds on the H₂O molecule to form H₂ and O₂ molecules will require energy (breaking the bonds requires energy)

This energy is usually called ∆H dissociation⁰

Is nuclear energy poised to be part of America’s future?

Answers

Answer:

Nuclear energy powers our businesses, homes and military. America’s 95 operating nuclear reactors generate approximately 20% of our nation’s electricity and provide over half of our carbon-free energy. They also create good-paying jobs at power plants and uranium mines. Wyoming produced 87% of America’s domestic uranium supply in 2018.

Today, nuclear energy faces serious hurdles. Regulatory costs and subsidies for renewable energy technologies are forcing America’s nuclear power plants to close at an alarming rate.

Russia and China are subsidizing their government-owned nuclear companies to assert their energy influence around the world. China is searching the globe for uranium reserves and investing heavily in the countries where it’s found. They want to secure more nuclear fuel for themselves and increase their control of the global supply.

Meanwhile, American nuclear power plants have come to rely on cheap Russian imports of uranium to meet their nuclear fuel needs. Right now, roughly 40% of the uranium coming into the United States originates in Russia or its satellite states of Kazakhstan and Uzbekistan. Russian-backed companies are developing fuel that can be placed directly in American reactors.

Explanation:

A mixture contains 21.7 g NaCI, 3.74 g KCI, and 9.76 g Lici. What is the mole fraction of NaCl in this mixture?

Molar mass
NaCl: 58.44g/mol
KCl: 74.55g/mol
LiCl: 42.39g/mol​

Answers

Answer:Mole Fraction of NaCl=0.5697

Explanation:

No OF Moles of NaCl=  Mass / Molar mass

=21.7 g/58.44g/mol

=0.371moles

No OF Moles of KCl=  Mass / Molar mass

=3.74g/74.55g/mol

=0.0502moles

No OF Moles of LiCl=  Mass / Molar mass

=9.76 g/42.39g/mol

=0.230moles

Mole Fraction of NaCL = Moles of NaCL/ Total number of moles of the mixture

=0.371/( 0.371+ 0.0502+0.230)

0.371/0.6512

=0.5697

Answer:

Mole fraction: 0.570

Explanation:

Mole fraction is defined as the ratio of moles of a compound in a mixture over the total moles of the mixture. To solve this problem, we need to find moles of the 3 salts:

Moles NaCl -Molar mass: 58.44g/mol-:

21.7g NaCl * (1mol / 58.44g) = 0.3713 moles

Moles KCl -Molar mass: 74.55g/mol-:

3.74g KCl * (1mol / 74.55g) = 0.0502 moles

Moles LiCl -Molar mass: 42.394g/mol-:

9.76g LiCl * (1mol / 42.394g) = 0.2302 moles

Mole fraction NaCl:

0.3713mol / (0.3713mol + 0.0502mol + 0.2302mol) =

0.570

(Science)The low pressure area near Earth’s equator is filled by cool air moving in from ________.

A

B

the North and South Pole
C

the Prime Meridian
D

the Atlantic and Pacific Ocean

Answers

Answer:

B . the North and South Pole

Explanation:

The equator is also called the doldrum or the region of calms here the winds are moving slowly and consist of warmth and moisture. Thus developing a low-pressure system.  Due to which the cool and dense winds that blow from the poles reach the equator and the warm winds move towards the poles balancing the temperatures in both the regions.  As these regions don't receive most of the sunlight they have high-pressure cells.

How are the cells of the bicep muscle similar to the cells of the heart muscle?
A. They digest food.
B. They make energy.
C. They use carbon dioxide.
D. They form tissue that moves.

Answers

Answer:

I believe it's D

Explanation:

they both are worked a lot and it makes the most sense.

The cells in both bicep muscle and heart muscle make energy for contraction and relaxation. Hence, option B is correct.

What is cardiac muscles ?

Cardiomyocytes have a rather rectangular form and are short and thin. They have a single nucleus, cell organelles that are identical to those seen in skeletal muscle cells, and many sarcosomes, which supply the energy needed for contraction.

Intercalated discs with gap junctions for diffusion and communication link cardiomyocytes structurally. Myofibrils, which in turn are composed of thick and thin myofilaments, make up the sarcoplasm.

Due to their high energy needs, skeletal muscle cells have many mitochondria that enable them to produce enough ATP. Therefore, the cells in the bicep muscles and cardiac muscles produce energy.

B. The moon
Tides are due to the gravitational forces of the Moon and the Sun. The tide is high when the moon or the sun or both are on the side of the sea and vice versa.
The effect of tides due to the moon is much greater than that of the sun, because the moon is much closer to the earth.
