Answer:

Explanation:

a) Zinc has a charge of plus 2 and hydrogen gas is H₂ so HCl would have a two in front to balance the equation

b) All have charges of plus one

c) Copper has a charge of plus two (given) and it needs two chlorine atoms to become stable and hence to balance the whole equation, you would need two moles of sodium hydroxide and sodium chloride

Answer:

1 mol SO2 contains 6.0213*10^23 molecules

6.023*10^24 molecules = 10 mol SO2

Equation

S(s) + O2(g) → SO2(g)

1 mol S reacts with 1 mol O2 to prepare 1 mol SO2

To prepare 10 mol SO2 you require : 10 mol S plus 10 mol O2

And that is the answer to the question

If you want a mass :

Molar mass S = 32 g/mol You require 10 mol = 320 g

Molar mass O2 = 32 g/mol :You require 10 mol = 320 g

What is the connection between Archimedes and the Mass-Volume lab
Usimov [2.4K]

Answer:

Explanation:

This question is not very clear, however, going by the key words in the question, Archimedes' principle shows a relationship between mass and volume.

Archemedes' principle states that when a body is fully or partially immersed in fluid, it is acted upon by an upward force which is equal to the weight of the fluid displaced by the body.

The volume displaced here can be determined using the formula

Density of liquid = mass displaced ÷ volume

Hence, volume = mass displaced ÷ density of liquid

An isotope of yttrium has 39 protons and 59 neutrons. what is the atomic mass of that isotope?
Charra [1.4K]
We can define atomic mass the total of number of protons and number of neutrons in an atom or isotope.
<span>So when an isotope of yttrium has 39 protons and 59 neutrons, its atomic mass is equal to;
number of protons + number of neutrons = 39 + 59 = 98</span>
