What is the hashing algorithm called used in Bitcoin?
Secure Hash Algorithm 256-Bit (SHA-256) -
Why is this hashing algorithm really hard (almost impossible) to brute-force?
As the target is a 256 alphanumeric value this turns out to have a ridiculously large number of possibilities for a single miner to find a block on their own (without needing an enormous amount of computing power already), adding to that it is essentially a lottery that requires more and more when a large amount of miners are already involved. In addition to that the ultimate hash output cannot be reversed to calculate the initial input data.

1- Secure Hash Algorithm SHA-256 is used in bitcoin.
2- No, it is not possible, for two reasons.
First, you would have to generate and hash an unimaginably large number of ECDSA keypairs to have a reasonable chance of finding a collision. With current computing power, that would take longer than the age of the universe.
Second, it is much more profitable to generate bitcoins if you have lots of computing power.

Secure Hash Algorithm (SHA). Namely SHA-256.
Why is this hashing algorithm really hard (almost impossible) to brute-force?
Because bitcoin uses a one-way hashing function. Meaning the beginning value cannot be identified even if the end value is known. Furthermore, the hashing algorithm is so sophisticated that even the slightest alteration to the value being encrypted gives totally different value of the hash, making it even more unpredictable to hackers.

SHA-256
The Hash rate increasese or decreases in levels of difficulty based on the proof of work algorithm to keep the network stable. The governing framework only allows the hash rate to change not more than 4x its previous value, keeping the network hash rate fluctuations within a considerate range

Mining has nothing to do with hash functions in itself. Mining utilizes hash functions in the PoW process and hashrate comes from the rate at how fast the network is solving hashes.
The reason why hash functions are hard to brute force is by the sheer number of possible outputs they can generate. 
SHA-256
The number of computational possibilities are so high with a 256 hash its astronomically difficult to match the hash.

ANS-secure hash algorithm (SHA-256) - Why is this hashing algorithm really hard (almost impossible) to brute-force?
ANS-because the whole bitcoin hash algorithm can only be resolved in a linear / uni-directional manner, it would be almost impossible to get those unique hash rates.

There are so many it would be incredibly hard. You have to try again and again.

SHA (Secure Hash Algorithm) -256. -
Why is this hashing algorithm really hard (almost impossible) to brute-force?
The “hash” process involves a sequence of numeric and alphabetic symbols (cryptography) as long as 256 symbols. It can only be delivered and solved in a one-way, linear direction, and once produced (like blending ingredients together) it can not be undone. Hash mash :}

- For each input you get one output, and reversing the process would need an immense amount of time and computational power.

1 - Bitcoin uses a Secure Hash Algorithm (SHA) named SHA-256.
2- Bitcoin hash algorithm produces unique hashes. Each hash provides a random number between zero and a maximum 256 digit value; therefore, it’s impossible to find a matching one. Also a hash function is a one-way function. You cannot go from an output to an input.

Secure Hashing Algorithm SHA-265
Invented by the NSA - Not Satoshi Nakamoto
- Why is this hashing algorithm really hard (almost impossible) to brute-force?
The SHA-265 algorithm goes one way only so it cannot be reversed. The only way would be to duplicate it by putting in exactly the same data.
2^256 is the number of possible SHA256 hashes so it would be very time consuming and electricity consuming process to try every possible combination.

The hashing algorithm used for bitcoin is call a Secure Hashing Algorithm (SHA-256).

The hashing algorithm is extremely difficult to brute force because it is a 256 character string with randomising inputs whereby there is seemingly no correlation between it’s inputs. For example, a single space added to the SHA function will change most of (if not all) of the output. Reverse-engineering the output of the function is near impossible.

- The algorithm turns input into output but not the other way around so it is impossible to derive the function. Simply guessing random uppercase and lowercase letters and numbers would take multiple lifetimes and more energy than is available to country let alone an individual.

it’s a one way function and I believe the prime number has 80 digits, so real hard to guess that number
