Why a mixture of ch3cooh and ch3coona can act as a buffer while a mixture of hcl and nacl can not?

Buffers are made out of what are called weak acids or weak bases. Mixtures of CH3COOH and CH3COONa can act as buffers because they don't break apart completely in solution like HCl and NaCl. As the CH3COOH and CH3COONa are in solution they keep the pH constant by either donating or accepting protons because they don't act like strong acids or bases.
HCl is known as a strong acid where the hydrogen disassociates completely from the chloride.
NaCl is not a buffer because it dissolves completely as welll

What is the Chemical equation for vinigar and salt for my project?
vinegar's chemical formula is CH3COOH, while salt is NaCl Now Na+ and Cl- are both specator ions. So if the mixture is in water then the equation will go as fallows. CH3COOH + NaCl + H2O ------ NaCH3COO + Cl- + H3O
Equal lengths of Mg ribbon are taken in test tubes A and B. HCl is added to test-tube A while CH3COOH is added to test-tube B. In which test tube will the fizzing occur more and why?
Fizzing will occur more in test tube A because: i) HCl is a strong acid while CH3COOH is a weak acid ii) HCl completely dissociates into H+ and Cl- ions while CH3COOH wont completely ionise!!!
Role of Cl in TE buffer solution?
TE buffer is a often used as a buffer solution in molecular biology, mainly in procedures involving DNA or RNA. The purpose of TE buffer is to solubilize DNA or RNA, while protecting it from degradation.
What is the difference between a mixture and a coumpound?
A mixture is physically mixed while a compound is chemically combined.
What is the difference between heterogeneous mixtures and homogeneous mixtures?
Homogeneous mixture is a mixture that you cannot identify any substances because it's components is uniform while heterogeneous mixture is a mixture that you can identify the substances because it's components is not uniform and it varies.

What is the full name for te buffer?
It is a buffer used in biology. "te" is derived from its components: t from tris, a common pH buffer, and e from the EDTA, a molecule. The purpose of TE buffer is to solubilize DNA or RNA, while protecting it from degradation.

Why acetate buffer is used while isolating casein from milk?
pH of sodium acetate buffer is 4.6 and most of the proteins have 4.8 isoelectric pH (pI), so buffer maintains the pI of casein in the casein estimation from milk
Why gets function gives a warning every time you compile a c program?
It is unsafe. In order to use gets() safely, you need to know how many characters you will be reading to ensure your character buffer is large enough: char buffer[10]; while (gets (buffer) != 0) { ...process buffer... } The above code has undefined behaviour when the number of characters read is 10 or more (you need one character for the null-terminator). This is because the character buffer, str, decays to a pointer (referencing &str[0]) and the function, gets(), cannot determine the number of characters in a buffer by its pointer alone. The gets() function was dropped from the C standard in 2011, however some implementations still include it. To avoid the warning, use the fgets() function instead. This allows you to specify the length of your buffer and (when used correctly) prevents buffer overflow. char buffer[10]; while (fgets (buffer, 10, stdin) != 0) { ...process buffer... }
You can tell whether a mixture is a solution or a suspension when you?
letting the mixture stand for a while
How can you tell whether a mixture is a solution or a suspension by 1 freezing it 2 evaporating off the liquid 3 stirring it 4 letting the mixture stand for a while?
Letting the mixture stand for a while. For sure.
