A radioactive nuclide is used to detect eye tumors. An atom of this radionuclide contains 15 protons, 15 electrons, and 17 neutrons. Which is symbol of this radionuclide?
Superscript 32 subscript 17 upper P
Superscript 17 subscript 15 upper P.
Superscript 30 subscript 15 upper P.
Superscript 32 subscript 15 upper P.
Answers
Answer:
D. superscript 32 subscript 15 upper P
Explanation:
took the test
An atom of this radionuclide contains 15 protons, 15 electrons, and 17 neutrons. Superscript 32 subscripts 15 upper P is a symbol of this radionuclide. Therefore, option D is correct.
What is a radionuclide?A radionuclide is a type of nuclide that is unstable and undergoes radioactive decay. This means that the nucleus of the radionuclide is not stable and will spontaneously emit energy in the form of particles or electromagnetic radiation to become more stable.
The symbol of an element is determined by the number of protons in the nucleus, which is also known as the atomic number. In this case, the radionuclide has 15 protons, so it is an atom of phosphorus, which has an atomic number of 15.
The total number of nucleons in the nucleus (protons + neutrons) is 15 + 17 = 32. Therefore, the correct symbol for this radionuclide is Superscript 32 subscript 15 upper P, which represents an isotope of phosphorus with a mass number of 32.
Thus, option D is correct.

which phrase describes air pressure O decreases with denser air O decreases as altitude decreases O equals mass divIded by Volume O decreases as a result of fewer air particles pushing down
Answers
Air pressure decreases as altitude decreases. This phenomenon occurs because the atmosphere's density diminishes with increasing height above the Earth's surface and the correct option is option 2
As one ascends to higher altitudes, there are fewer air particles above, leading to a decrease in air density. Consequently, the pressure exerted by the air decreases at higher elevations.
Conversely, at lower altitudes, the air is denser due to the larger number of air particles above, resulting in higher air pressure. This relationship between air pressure and altitude is crucial for understanding weather patterns, climate changes, and the functioning of various natural processes on Earth.
Thus, the ideal selection is option 2.

Nicole has 2 glasses on the counter: one of water and one of sugar-water. She is baking a cake and needs to use the sugar-water for the glaze. Both glasses look identical, but one contains a mixture and the other contains a compound.
Is sugar-water a mixture or a compound? Define mixtures and compounds, and explain how, without tasting it, Nicole can test to make sure she is using the sugar-water in the glaze.
Answers
Answer:
sugar-water is a mixture not a compound.(homogeneous mixture.)
Explanation:
Compounds are substances formed by the chemical combination of two or more elements. Mixtures are substances formed by physically mixing two or more substances together.
The solution of sugar in water is considered a mixture not a compound because the particles of sugar and water are not completely dissolve nor mixed in a fixed proportion or ratio. hope this helped :)
Answer: Nicole can take a small amount of sample from both of the glasses, she can place the samples in two separate containers and leave them out in the sun, so that the water gets evaporated. One of the two containers will contain a residue of sugar. The one containing the sugar residue, is the sugar-water solution.

Answers
The strength of the bond is based on electronegativity difference between atoms ,larger the difference stronger is the bond.The strongest bond is that of HF.
An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms combine as per their electronegativity which gives bond different strengths.The electronegativity is largest between hydrogen and fluorine .Thus, HF has the strongest bond.

2.)B
Explanation:
The total mass of products obtained in the reaction; CaCO3→CO2+CaO is 30 grams. Given the reaction; Fe+O2→Fe2O3, atoms of Fe and O2 are rearranged during the reaction. During a chemical reaction, mass is conserved. Given the reaction NaHCO3+HC2H3O2→NaC2H3O2+H2O+CO2, we can see that the atoms of the reactants are regrouped during the reaction. Given the reaction 2H2+O2→2H2O, there are four atoms of hydrogen before and after the reaction.
According to the law of conservation of mass, atoms are neither created nor destroyed in a chemical reaction. Similarly, mass is neither created nor destroyed.
This means that the number of atoms of each element before and after the reaction must remain the same. A chemical reaction only involves the rearrangement of atoms in reactants to form products.
The total mass of reactants must be equal to the total mass of products according to the law of conservation of mass.

Explanation:
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. Some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. Understanding chemical changes is a major part of the science of chemistry.

What happens to the atoms that make up hydrogen fuel as it burns?
Answers
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.
