So i found out that the apollo 11’s guidance computer had 2k memory but like of what? 2,000 terabytes? basically i would like to know the units

1 K = 1024 bytes; 1 TB ≈ 10^12 bytes

A byte is a unit of computer storage that can hold a single character (e.g. the letter "a" or the nymber "2").

The symbol K stands for kilobytes.  

A kilobyte (K or KB) is 2^10 bytes = 1024 bytes ≈ 1000 bytes.

Thus, the Apollo computer had 2048 bytes (about 2000 bytes) of memory.

A terabyte (TB) is 2^40 bytes = 1.099 511 627 776 × 10^12 bytes ≈ 10^12 bytes

chemical properties are the characteristic of matter which can only be observed by changing the chemical identity of a sample like flammability reactivity and toxicity.

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
