Which balanced equation represents an oxidation-reduction reaction?(1) BaCl2 + Na2SO4==>BaSO4 + 2NaCl
(2) C+H2O ==>CO + H2
(3) CaCO3==>CaO + CO2
(4) Mg(OH)2 + 2HNO3==>Mg(NO3)2 + 2H2O

Answers

Correct Answer: option 2 i.e. (2) C+H2O ==>CO + H2

Reason:
Reaction is said to be oxidation-reduction (redox) type, when one species undergoes oxidation, while other species undergoes reduction. In present case, during the course of reaction, carbon is oxidized from '0' to '+2'. On other hand, hydrogen is reduced from '+1' to '0'.

The answer is (2). The oxidation-reduction reaction means that there is electrons transfer in the reaction. So there is valence change of at least two elements evolving in the reaction.

A pain-relieving pill has a mass of 0.005 g. Express the pill’s mass in grams using scientific notation or in milligrams.

Answers

Answer : The mass represented in scientific notation as $5.0* 10^(-3)g$ and the mass in milligram is, 5 mg

Explanation :

Scientific notation : It is the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.

For example :

5000 is written as $5.0* 10^3$

889.9 is written as $8.899* 10^(-2)$

In this examples, 5000 and 889.9 are written in the standard notation and $5.0* 10^3$ and $8.899* 10^(-2)$ are written in the scientific notation.

If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.

As we are given the 0.005 g in standard notation.

Now converting this into scientific notation, we get:

$\Rightarrow 0.005g=5.0* 10^(-3)g$

As, the decimal point is shifting to right side, thus the power of 10 is negative.

Thus, the mass represented in scientific notation as $5.0* 10^(-3)g$

Now we have to determine the mass in milligram.

The conversion used from gram to kilogram is:

1 gram = 1000 milligram

or,

1 g = 1000 mg

As we are given the mass 0.005 grams.

As, 1 gram mass = 1000 mg

So, 0.005 gram mass = $(1000g)/(1g)* 0.005mg=5mg$

The mass in milligram is, 5 mg

$\boxed{ \ 5.0 * 10^(-3) \ grams \rightarrow 5.0 \ milligrams \ }$

Further explanation

Scientific notation represents the precise way scientists handle exceptionally abundant digits or extremely inadequate numbers in the product of a decimal form of number and powers of ten.

Put differently, such numbers can be rewritten as a simple number multiplied by 10 raised to a certain exponent or power. It is a system for expressing extremely broad or exceedingly narrow digits compactly.

Scientific notation should be in the form of

$\boxed{ \ a * 10^n \ }$

where

$\boxed{ \ 1 \leq a \ < 10 \ }$

The number "a" is called "mantissa" and the exponent "n" the order of magnitude.

The exponent tells about the size of the number.

A positive exponent indicates a number greater than or equal to 1.
A negatifive exponent indicates a number between 0 and 1.

From the key questions asked, we face the standard form of 0.005 grams which will be converted into scientific notation.

$0.005 = (5)/(1,000)$

The coefficient (or mantissa) is 5, which has fulfilled the interval 1 ≤ a < 10.
The denominator consists precisely of three zero digits.

Hence, 0.005 grams is written in scientific notation as $\boxed{ \ 5.0 * 10^(-3) \ grams \ }$

Because 1 milligrams is equal to 10⁻³ grams, then

$5.0 * 10^(-3) \ grams * (1 \ milligrams)/(10^(-3) \ grams)$

Hence, 0,005 grams is 5.0 milligrams.

In science, we frequently must deal with extremely small or incredibly large quantities. For a typical example, one of the recognized limitations of the microwave frequency is 300,000,000 Hz with a photon energy of 0.00000124 eV. They with many zeros can be impractical to work with, so scientists properly implement scientific notation.

The inverse of scientific notation is the standard form. To promptly change scientific notation into standard form, we reverse the process, move the decimal point to the right or left. This expanded form is called the standard form.

$\boxed{ \ 3.0 * 10^(8) \ Hz \ \rightarrow 300,000,000 \ Hz \ or \ 300 \ MHz \ }$

$\boxed{ \ 0.00000124 \ eV \ \rightarrow 1.24 * 10^(-6) \ eV \ or \ 1.24 \ \mu eV \ }$

Explain how the scientific definition of work is different from the everyday meaning

Answers

In every day life work is a job while in scientific terms the work is a change in energy due to applied force and displacement.

Work(Job) -

In every day life, work means an specific job that is assigned to people.

For example: I work as account assistant in the company.

Work:

In scientific terms the work is a product of applied force and displacement. It is measured in Joule.

For example- the engine did the 10 J of work.

Therefore, in every day life work is a job while in scientific terms the work is a change in energy due to applied force and displacement.

43 Which temperature change indicates an increase in the average kinetic energy of the molecules in a sample?(1) 15°C to 298 K (3) 305 K to 0°C(2) 37°C to 273 K (4) 355 K to 25°C

Answers

The temperature change indicates an increase in the average kinetic energy of the molecules in a sample is 15°C to 298 K. Thus option 1 is correct.

What is kinetic energy?

Kinetic energy is defined as a form of energy that an object or particle has by the reason of its movement.

It can also be defined as the measure of the work that an object does by virtue of its motion.

Average kinetic energy is defined as a product of half of the mass of each molecule and the square of RMS speed.

The kinetic energy id directly proportional to temperature, with increase in temperature kinetic energy increases.

Thus, the temperature change indicates an increase in the average kinetic energy of the molecules in a sample is 15°C to 298 K. Thus option 1 is correct.

Describe what happens to a hydrogen bond between two water molecules

Answers

Explanation:

Hydrogen atoms of one water molecule are attracted towards the oxygen atom of a neighboring water molecule can be termed as an intramolecular bond.

Generally, the oxygen atom is partially negatively charged, and the hydrogen atom is partially positively charged, so an arttraction occurs which forms this hydrogen bond. The attraction of the O-H bonding electrons towards the oxygen atom leaves a deficiency on the far side of the hydrogen atom relative to the oxygen atom. The result is that the attractive force between the O-H hydrogen and the O-atom of a nearby water molecule is strong.
