What else can I help you with?
Do chiral centers have to be carbon atoms?
Yes, chiral centers do not have to be carbon atoms. Any atom that is bonded to four different groups can be a chiral center.
When water changes to ice the link up of atoms does or does not change?
The bonds between hydrogen and oxygen atoms of individual water molecules do not change when liquid water changes to ice. This is a physical change called freezing, and does not cause any chemical changes to occur. Only chemical changes can cause changes in chemical bonds.
What atoms vibrate around a fixed point but do not change positions?
Atoms in a solid can vibrate around fixed points but do not change positions. This movement is known as thermal vibration, where atoms oscillate around their equilibrium positions without any net displacement. This phenomenon contributes to the thermal energy of the solid.
When chlorine atoms are bonded together what are they called?
When two chlorine atoms bonded together, the molecule is simply called chlorine since Cl2 is the way that chlorine occurs naturally.
Is wax solidifying a physical or chemical change?
Yes becasue when the atoms inside the wax start to change, they all form and become a solid. this is what is now called replacement.
Which atoms do not have any protons?
Atoms that do not have any protons are called neutrons.
When matter undergoes a physical or change are any atoms created ordestroyed?
in a nuclear reaction, matter (atoms) will be converted to energy. Other than that, no. That is called the conservation of mass.
Can a circle be drawn with any center and any radius?
The center of a circle is the same for all circles but the length of the radius can change
Do chiral centers have to be carbon atoms?
Yes, chiral centers do not have to be carbon atoms. Any atom that is bonded to four different groups can be a chiral center.
Two atoms linked together is called?
Any number of atoms joined together by means of chemical bonds is called a molecule. The number of atoms in a particular molecule varies.
When ice changes to water the link up of atoms does or does not change?
The bonds between hydrogen and oxygen atoms of individual water molecules do not change when liquid water changes to ice. This is a physical change called freezing, and does not cause any chemical changes to occur. Only chemical changes can cause changes in chemical bonds.
Is it true that an anion is any atom or group of atoms with a positive change?
false
What Circle on Earth's surface has the center of Earth as its center?
Any circle on the Earth's surface whose center is at the center of the Earth is called a "great circle". Any circle with its center anywhere else is called a "small circle". Spiritually, many consider the kaaba (Mecca) to be the center of the Earth's surface.
A chemical change is any change that?
In a macrscopic scale: alters colour, scent, texture.In a microscopic scale: Break bonds between atoms in a molecule and/or forms new bonds between atoms.
What is the force that holds any 2 atoms in a molecule called?
intermolecular force
What is a line segment from the center of a circle called?
A line from the center of a circle to any point on the circle is called a radius.
What is the distance from the center to any point on the circle called?
radius
