<u>Answer:</u> The mass of water reacted is 36 grams

<u>Explanation:</u>

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

This also means that total mass on the reactant side must be equal to the total mass on the product side.

The chemical equation for the reaction of sulfur dioxide with bromine and water follows:

SO_2+Br_2+2H_2O\rightarrow 2HBr+H_2SO_4

Let the mass of water be 'x' grams

We are given:

Mass of sulfur dioxide = 64.1 grams

Mass of bromine = 159.9 grams

Mass of hydrogen bromide = 161.9 grams

Mass of sulfuric acid = 98.1 grams

Total mass on reactant side = 64.1 + 159.9 + x  = 224 + x

Total mass on product side = 161.9 + 98.1 = 260 g

So, by applying law of conservation of mass, we get:

224+x=260\\\\x=(260-224)=36g

Hence, the mass of water reacted is 36 grams.

Answer:

The answer to your question is:

a) 36 g of water

Explanation:

MW SO₂ = 32 + 32 = 64 g

MW Br = 80 g

MW H₂O = 18 g

MW HBr = 81 g

MW H₂SO₄ = 98

Balanced reaction:

                      SO₂   +   2Br   +   2H₂O    ⇒    2HBr   +   H₂SO₄

                     64g       2(80)        2(18)             2(81)            98

                     64.1       159.9                           161.9             98.1

Rule of three with Br and H2O

                              160 g ----------------   36 g

                              160 -------------------    x

           x = 160(36)/160 = 36 g oh water

Isotopes of an element will contain the same number of protons and electrons but will differ in the number of neutrons they contain. In other words, isotopes have the same atomic number because they are the same element but have a different atomic mass because they contain a different number of neutrons.

kumpel [21]

Answer:

modular

Explanation:

<em>The addition of extra liquid protein supplement to the tube feeding formula of Alice is an example of modular formula.</em>

<u>A modular formula consists of a deficient food supplements that is specifically rich in a particular macronutrient such as protein, carbohydrate, etc. </u>

The supplements in modular formula are usually in liquid from and are introduced into the tube feeding formula of a patient undergoing tube feeding.

In this case, the macronutrient in the liquid food supplement being given to Alice is protein.

Q1: Erosion and weathering are often confused. How is erosion different from weathering? Give an example of each.
stepan [7]

Explanation:

1.

Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils whereas erosion is the movement of weathered materials from one area to the other.

Erosion moves weathered materials and it causes them to change position. For example loose chips of rocks broken down as the rock weakens through alternate wetting and drying in tropical regions will remain in-situ until the agents of erosion comes to carry them away. The breaking is weathering and the carrying is erosion.

2.

Examples of mechanical weathering:

  •   Frost action
  •   Pressure release

Examples of chemical weathering:

  • Oxidation
  • Carbonation

There are two types of weathering:

  • In mechanical weathering, a rock disintegrates into smaller chunks by the action of wind, water and glacier. For example in temperate and polar regions, water within rocks freezes. When water freezes it expands and causes tension within the rock. When temperature drops, water melts and the tension is relieved. This process causes a rock to crack. The crack will eventually become wider with time.
  • In chemical weathering, a rock decomposes by the action of chemicals formed in the rock. In karst regions where limestone forms, combination of rain water and carbon dioxide forms weak carbonic acid that reacts with calcite in limestone.
