Answer:

B. CO + H₂O → H₂ + CO₂

Explanation:

Redox reaction -

It is the type of reaction , where the process of oxidation and reduction takes place simultaneously , is known as a redox reaction .

Oxidation refers to the addition of oxygen atom or the removal of hydrogen atom .

And ,

Reduction refers to the addition of hydrogen atom or the removal of the oxygen atom .

From the options given in the question , the only reaction , which have both the process of oxidation as well as reduction , is -

CO + H₂O → H₂ + CO₂

In the above reaction ,

Oxidation process - CO → CO₂ ,

The addition of oxygen atom .

Reduction process - H₂O → H₂ ,

The removal of oxygen atom .

Calculate the ratio of the mass ratio of SS to OO in SOSO to the mass ratio of SS to OO in SO2SO2. Consider a sample of SOSO in

Veronika [31]

Answer:

The ratio of the mass ratio of S to O; in SO, to the mass ratio of S to O; in SO₂, is 2:1

Explanation:

According to the consideration, let us first find the ratio of S and O in both the compounds

For SO:

$\frac{m_{S} }{m_{O} }= \frac{32}{16}\\\\ \frac{m_{S} }{m_{O} }= 2$

Let us express it as

$SO_{\frac{m_{S} }{m_{O} }} = 2$

For SO₂,

Due to two oxygen atoms in the molecule, the mass of oxygen will be taken two times

$\frac{m_{S} }{m_{O} }= \frac{32}{(2)(16)}\\\\ \frac{m_{S} }{m_{O} }= 1$

Let us express it as

$SO_2_{\frac{m_{S} }{m_{O} }}= 1$

Now, for the ratio of both the above-calculated ratios,

$\frac{SO_{\frac{m_{S} }{m_{O} }}}{SO_2_{\frac{m_{S} }{m_{O} }}}=\frac{2}{1}$

The required ratio is 2:1

Science is based primarily on peoples opinions and views of the subject matter.

kvv77 [185]

Answer:

False

Explanation:

Science is not based on primarily on peoples opinions and views of the subject matter whereas science is based on empirical observations and research for its validity.

Science aims to find answers to human questions related to the natural world through their research observation and experiments. Scientists and researchers provide valid proof of human questions so that people can trust them.

Science can change people's opinions regarding the natural world with valid proof and observational theories but science is not based on people's opinion.

Hence, the given statement is "false".
