<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

_____ might be able to detect tumors based on its use of X-rays and ability to produce cross-sectional images of the brain.
MatroZZZ [7]

Answer: CAT (computerized axial tomography) scan

Explanation:

Computerized Axial Tomography (CAT) scan is an X-ray examination in which a computer generates images showing cross-section views of a patient's internal parts (brain, blood vessels and etc.)

CAT scan can identify normality and detect abnormalities (such as tumor and degenerated cells) in the internal organs and structures and hence, this information are used to guide other medical processes.

I NEED HELP ASAP!!! THIS IS A 30 POINT QUESTION!!!
bekas [8.4K]

Answer:

4

Explanation:

Protein synthesis involves two major steps:

  1. <em>Transcription of the DNA to mRNA (a form of RNA)</em>
  2. <em>Translation of the mRNA molecule into a protein.</em>

<em></em>

Transcription involves the formation of a nucleotide sequence complementary to the DNA molecule, with the pairing of a different base, Uracil, with Guanine instead of the usual Thymine base. This occurs in the nucleus of the cell, and the resulting molecule is known as the mRNA.

This mRNA is transported into the cytoplasm through the nuclear pore for the next step, translation. This is primarily accomplished by ribosomes and tRNA molecules which are present in the cytoplasm of the cell. The result of this step is the generation of a protein molecule.
