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 )

How many moles of H2 are produced when 2.54 moles of H2O reacted?
Answers
Answer:
2.54mole of H₂
Explanation:
The reaction expression is given as:
2H₂O → 2H₂ + O₂
Given;
Number of moles of H₂O = 2.54moles
Unknown:
Number of moles of H₂ produced = ?
Solution:
To solve this problem, we use the concept of mole comparison. Now from the reaction expression, we know that;
2 mole of H₂O will produce 2 mole of H₂
2.54 mole of H₂O will then produce 2.54mole of H₂

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.

Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, the electronic configuration of vanadium is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d³.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.
The systematic distribution of electrons in the various atomic orbitals is called its electronic configuration. The atomic number of vanadium is 23. The electronic configuration of vanadium is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d³. The noble gas electronic configuration of vanadium is [Ar]3d³4s². 1,2,3 represents the number of shells and s and represents the orbitals. The superscripts represents the number of electrons in each orbitals.

The main difference between SPECT and PET scans is the type of radiotracers used. While SPECT scans measure gamma rays, the decay of the radiotracers used with PET scans produce small particles called positrons. A positron is a particle with roughly the same mass as an electron but oppositely charged.
Explanation:
a2
While imaging tests such as X-rays can show what the structures inside your body look like, a SPECT scan produces images that show how your organs work. For instance, a SPECT scan can show how blood flows to your heart or what areas of your brain are more active or less active.
a3
PET and SPECT have been extensively evaluated as diagnostic procedures for dementia. Substantial progress has been made in developing radioligands that bind to amyloid deposits in the brain, which should provide new opportunities for early diagnosis and treatment monitoring in Alzheimer's disease
a4
What are the disadvantages of spect as compared to pet?
However, SPECT has issues, including long scan times and low-resolution images prone to artifacts and attenuation. Some artifacts can easily be misidentified as perfusion defects. SPECT also does not provide a quantifiable estimate of the blood flow, whereas PET does, experts say.
