Microwaves are one type of electromagnetic radiation. compared to all other types of electromagnetic radiation, radio waves have the lowest frequency.<span> Radiant energy is energy that travels by radiation. an example of this is light. Yes microwaves are a type of infrared rays .</span>
acid
when a metal hydroxide reacts with acid it forms a salt and water, for example:
lithium hydroxide + hydrochloric acid → lithium chloride (the salt) + water
Answer:
2.1
Explanation:
Calculation of moles of 
Mass of copper = 5.3 g
Molar mass of copper = 315.46 g/mol
The formula for the calculation of moles is shown below:
Thus,
Moles of = 0.0168 moles
According to the reaction,
1 mole of react with 1 mole of 
0.0168 moles of react with 0.0168 moles of
Moles of = 0.0168 moles
Molar mass of = 126.07 g/mol
Thus,
<u>Mass = Moles * Molar mass = 0.0168 moles * 126.07 g/mol = 2.1 g</u>
<u>Answer - 2.1</u>
The answer is (3) 0.193M. To find the molarity of HNO3, you just need to use the M1V1=M2V2 equation (no need to worry about ionization constants because HNO3 is monoprotic and KOH dissociates 1:1). Since the molarity you are looking for is M1, you get M1=M2V2/V1=(0.150)(32.1)/25.0= 0.193M
