Answer:

The oxidation number of sulphur in is +2

Explanation:

<em>S</em><em>2</em><em>O</em><em>3</em><em> </em><em>2</em><em>-</em>

<em>2</em><em> </em><em>(</em><em>S</em><em>)</em><em> </em><em>+</em><em> </em><em>3</em><em>(</em><em>O</em><em>)</em><em>=</em><em>-</em><em>2</em>

<em>2</em><em> </em><em>(</em><em>S</em><em>)</em><em> </em><em>+</em><em> </em><em>3</em><em>(</em><em>-</em><em>2</em><em>)</em><em>=</em><em>-</em><em>2</em>

<em>2</em><em> </em><em>(</em><em>S</em><em>)</em><em> </em><em>+</em><em> </em><em>(</em><em>-</em><em>6</em><em>)</em><em> </em><em>=</em><em>-</em><em>2</em>

<em>2</em><em> </em><em>S</em><em> </em><em>=</em><em> </em><em>+</em><em>4</em>

<em>S</em><em>=</em><em> </em><em>+</em><em /><em>2</em><em />

You find a ring with a mass of 107g . You fill a graduated cylinder up with 10ml of water and put the ring into the cylinder . T
Korvikt [17]

Answer:

5 mL

Explanation:

Given data:

mass of ring = 107 g

volume of water = 10 mL

increase in volume = 15 mL

How much water displace = ?

Solution:

V (ring) = V (water + ring) - V (water)

V (ring) = 15 mL -  10 mL

V (ring) = 5 mL

when the ring is put into cylinder, volume is increased by 15 mL. The volume of water was 10 mL so water is displaced by 5 mL and the volume 5mL is the voulme of ring.

The balanced chemical equation for the reaction of copper (Cu) and silver nitrate (AgNO3) is shown below.
lesantik [10]
Remark
The balance numbers in front of Ag and AgNO3 are both 2. That number is in moles.

Rule: if the moles are the same in the equation, then whatever you are given for one, will be the same for the other. So you have 0.854 moles of Ag. You will also have 0.854 moles of AgNO3 

Answer: 0.854 <<<<<

13) Find the mass, in grams, of 5.75 liters of N2.
faltersainse [42]
Molecular weight of N2
gram Atomic weight of N is 14 g.
gram Molecular weight = 14 g×2
= 28 g
Liter concepts
1 liter of gas always occupies 1 gram molecular weight .
Application of the concept
5.75 liter gives 0.257g


1 mole will occupy 28 g

0.257 will occupy 28 g × 0.257
= 7.196 g

The mass of the gas is 7.196 g.

Hope it helps you
