Answer : The correct option is, (B) 175 g

Explanation : Given,

Mass of mixture = 225 g

Mass of baking soda = 50 g

Now we have to calculate the mass of water.

Mass of mixture = Mass of baking soda + Mass of water

Mass of water = Mass of mixture - Mass of baking soda

Now put all the given values in this expression, we get the mass of water.

Mass of water = Mass of mixture - Mass of baking soda

Mass of water = 225 g - 50 g

Mass of water = 175 g

Therefore, the original mass of water added was 175 grams.

All you have to do is subtract

225g - 50g = 175g

Is wine a homogenous mixure
Fiesta28 [93]

Tap water and rain water are both homogeneous, even though they may have different levels of dissolved minerals and gases. A bottle of alcohol is a man-made homogeneous mixture, from a fine Italian wine to a glass of Scotch whisky. In the human body, blood plasma is an example of a homogeneous mixture.

If you had excess chlorine, how many moles of of aluminum chloride could be produced from 19.0 g of aluminum?
SIZIF [17.4K]
The chemical reaction would be written as follows:

2Al + 3Cl2 = 2AlCl3

We are given the amount of aluminum to be used in the reaction. This will be the starting point of the calculations. We do as follows:

19.0 g Al ( 1 mol / 29.98 g ) ( 2 mol AlCl3 / 2 mol Al ) = 0.63 mol AlCl3
