How could you increase the atomic number?
Answer:
So the atomic number increases with each element. The atomic mass is the sum of the protons and neutrons. As the atomic number increases it causes an increase in the atomic mass. However sometimes there is not a corresponding increase in the number of neutrons...

How many atoms of oxygen are in a molecule of glucose (C6H12O6)?
Record your answer. Be sure to use the correct place value.
Answer:
There are 6 oxygen atoms.
Explanation:
Glucose has a chemical formula of: C6H12O6 That means glucose is made of 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms.
hope this helps
The molecular formula of glucose is C₆H₁₂O₆, therefore one molecule of glucose has six oxygen atoms.
What is the chemical formula?A chemical formula is a way of representing information about the chemical proportions of atoms of each element that are present in a molecule or chemical compound. The chemical formula can be written by using chemical symbols, numbers, and other symbols, such as commas, dashes, brackets, and plus (+) and minus (−) signs.
A chemical formula of a compound contains no words but can represent certain simple chemical structures. Chemical formulae are usually more limited in power than structural formulae and chemical names. There are two types of chemical formulas one empirical formula and another molecular formula.
In a molecular formula, more than one atom of the same element can be represented by subscripts. The given formula of glucose is C₆H₁₂O₆ and the total number of oxygen atoms in the formula is equal to six.

I need help with this
Answer: B
Explanation: All you have to do to find out if an equation is balanced is count the number of atoms on each side. To be balanced, they must be equal.
In case you didn’t know: The number in front of an element or compound means that you will multiply. For instance, 2AlBr3 would have 2 Al atoms and 6 Br atoms. The subscript number just means how many atoms there are in that compound.
why is it true that particles in a rock lying on the group have kinetic energy and energy
Answer:
Particles of objects have both kinetic and potential energy. Because particles are constantly in motion, they have kinetic energy. These particles are arranged in specific ways in different objects. Therefore, they also have potential energy.

What are they? GIVING BRIANLIEST TO WHOEVER IS RIGHT.
vascular and nonvascular
brown seeds and green seeds
nonflowering and flowering
fruits and vegetables
Answer: nonflowering and flowering
Explanation: i just did the quiz
Seed plants are divided into two groups, are nonflowering and flowering plants. Therefore, option C is correct.
What is flowering plant ?Flowering plants create blooms, which they then use as seeds to develop more of their kind or other plants. Nonflowering plants don't produce flowers; instead, they produce microscopic reproductive components called seeds or spores that can be used to create additional plants that look exactly like them.
Gymnosperms and angiosperms are frequently used as arbitrary divisions for the seed plants. The difference between the two is based on the fact that angiosperms produce blooms, whereas gymnosperms do not.
An ovary surrounds the angiosperm seed. A seed grows on the size of a cone in gymnosperms. Inside an ovary, only an angiosperm seed can grow.
Thus, option C is correct.

Which reason best explains why plasmas are good conductors of electricity? They have mobile charged particles. They are at extremely high temperatures. They are made up of particles in fixed positions. They have slow-moving nuclei that carry electricity.
Answer:
They have mobile charged particles.
Explanation:
Plasma refers to very hot matter such that the electrons in matter are ripped away from the atoms leading to the formation of an ionized gas.
We know that the carriers of electricity are charged particles. Any state of matter that has an abundance of charge carriers will definitely be a good conductor of electricity.
Therefore, plasmas are good conductors of electricity because they have a lot of mobile charged particles.
