Develop a relationship (in the form of a single sentence or equation) that can predict the charge based on the number and types of particle.
Answers
Answer:
The charge of an atom is determined by the ratio of protons to electrons
Explanation:
I hope this helps!!
A relationship showing the charge on an atom can be expressed as ;
Types of particle are protons and electrons Charge on atom = ( Number of protons - Number of electrons )The charge an atom posses depends on the particles/components of the atom which are protons and electrons. The protons are positively charged ions that are present in the nucleus of an atom while electrons are negatively charge ions present in the outer shell of an atom.
To predict the charge on an atom we will determine the difference between the number of protons and the number of electrons present in an atom.
Hence we can conclude that the relationship can be expressed as Types of particle are protons and electrons , Charge on atom = ( Number of protons - Number of electrons )

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 explanationDelta 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

a. The Earth’s revolution b. The Moon c. asteroids d. comets
Answers
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.

OH⁻
The electron dot notation shows only the chemical symbol of the element surrounded by dots to represent the valence electrons. The chemical symbol denotes the nucleus and all electrons except the valence electrons.
The dots are arranged on the four sides in pairs.
Oxygen is made up of 6 valence electrons, and since the ion has a net negative charge, the hydrogen and oxygen achieved their stable configuration this way.

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.What does a salt bridge do?

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
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.

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

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.
