Answer:
D.+1°e symbol represents a type of radiation that has the same mass as an electron and a positive charge.
Answer:
4.10x10⁻³g.
4.10 mg.
Explanation:
Hello,
In this case, considering the given number, we can see it has two digits after the first nonzero digit that is four (4) which is also at the third decimal place, it means that the scientific notation has a negative power as it is at the left of the given zeros, therefore it is:
4.10x10⁻³g.
Moreover, since the proper prefix for the factor x10⁻³ is milli, the number with prefix is:
4.10 mg.
Best regards.
Answer:
3.79 grams
Explanation:
22.4= STP volume . Molar mass of NH3=17.031
5.00 NH3 × (1 mol/22.4 L) =0.223
convert to grams->
0.223× 17.031= 3.79
1. Gas particles can move past each other
2. Gas particles flow easier
A group of covalently bonded atoms that has an overall electrical charge is called a polyatomic ion.
<h3>
What is polyatomic ion?</h3>
A polyatomic ion, also known as a molecular ion, is a covalently bound set of two or more atoms or a metal complex that behaves as a single unit and has a net charge that is more than zero. Depending on the meaning, the term molecule may or may not be used to refer to a polyatomic ion. In Greek, the word poly- means "many," however even ions of two atoms are usually described as polyatomic.
