A microorganism is an organism (living thing) that can't be seen with just your eyes. It can only be seen when viewed through a microscope. Some examples are: bacteria, viruses, and archaea.
The prefix "poly-" means "many," and "atomic" refers to atoms, so a polyatomic ion is made of 2+ atoms covalently bonded together. These ions are charged, which is why they can never stand alone.
Answer:
two
Explanation:
When two distinct elements are chemically combined, chemical bonds form between their atoms. the result is called a chemical compound
Answer:
39.1 °C
Explanation:
Recall the equation for specific heat:

Where q is the heat, m is the mass, c is the specific heat of the substance (in this case water), and delta T is the change in temperature.
You should know that the specific heat of water is 1 cal/g/C.
Using the information in the question:

The final temperature is about 39.1 °C.
