Example: 
<span>CH4 + 2 O2 → CO2 + 2 H2O </span>

<span>In the balanced equation above, 1 mole of CH4 will react with 2 moles of O2 to produce 1 mole of CO2 and 1 mole of H2O. </span>
<span>The mass of 1 mole of CH4 = 12 + (4 * 1) = 16 grams </span>
<span>The mass of 2 moles of O2 = 2 * 32 = 64 grams </span>
<span>Total mass of reactants = 16 + 64 = 80 grams </span>

<span>The mass of 1 mole of CO2 = 12 + (2 * 16) = 44 grams </span>
<span>The mass of 2 moles of H2O = 2 * 18 = 36 grams </span>
<span>Total mass of products = 44 + 36 = 80 grams </span>

<span>Before the reaction, there was 80 grams of matter, and after the reaction there is 80 grams of matter! </span>
<span>Matter is conserved!

</span>

Determine the image distance and image height for a 5.00 cm tall object placed 30.0 cm from a double convex lens with a focal le
vlabodo [156]

Answer:

The image distance is 30 cm

image height = - 5 cm

Explanation:

The formula for calculating the image distance is expressed as

1/f = 1/u + 1/v

where

f is the focal length

u is the object distance

v is the image distance

From the information given,

u = 30

f = 15

By substituting these values into the formula,

1/15 = 1/30 + 1/v

1/v = 1/15 - 1/30 = (2 - 1)/30 = 1/30

Taking the reciprocal of both sides,

v = 30

The image distance is 30 cm

magnification = image height/object height = - v/u

Given that object height = 5 cm, then

image height/5 = - 30/30 = - 1

image height = - 5 * 1

image height = - 5 cm
