<u>Given data:</u>

Volume of solution measured = 0.0067 L

<u>To determine:</u>

The number of significant figures

<u>Explanation:</u>

Significant figures are the number of digits that accurately describe a measured value.

As per the rules:

All non-zero digits are significant

Leading zero's i.e. the zero's after a decimal which comes before a non-zero digit are not significant

Hence in the given value 0.0067, there are 2 significant figures (6 &7)

Answer:

Digits in the measurement are significant figures are '6' and '7'.

Explanation:

Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

Rules for significant figures:

Digits from 1 to 9 are always significant and have infinite number of significant figures.

All non-zero numbers are always significant. For example: 604, 6.49 and 65.4 all have three significant figures.

All zero’s between integers are always significant. For example: 5005, 4.805 and 50.06 all have four significant figures.

All zero’s preceding the first integers are never significant. For example: 0.0058 has two significant figures.

All zero’s after the decimal point are always significant. For example: 4.500, 47.00 and 550.0 all have four significant figures.

Significant figures in measurement 0.0067 liter = 2

Digits in the measurement are significant figures are '6' and '7'.

Assuming 1 mol of Fe3+ and 2 mol of SCN- were allowed to react and reach equilibrium. 0.5 mol of product was formed. The total v
zaharov [31]

Answer:

a. 0.5 mol

b. 1.5 mol

c. 0.67

Explanation:

Fe3+ + SCN- -----> [FeSCN]2+

a. The ratio of the product to Fe3+ is 1:1. Meaning that if 0.5 mol of product was produced up then 0.5 mol of Fe3+ was used. Leaving 0.5 mol remaining at equilibrium

b. The ratio of the product to SCN= is 1:1. Meaning that if 0.5 mol of product was produced up then 0.5 mol of SCN- was used. Leaving 1.5 mol remaining at equilibrium

c. KC =  0.5/(0.5*1.5) =  0.67

Which option defines kinetic energy?(1 point)
MAVERICK [17]

The option which accurately defines kinetic energy from the choices above is:

the energy an object has because of its motion

The correct answer choice is option c

In order words, kinetic energy is that type of energy which a body or an object posess due to its relative motion.

<h3>What is energy?</h3>

Energy can simply be defined as the capacity of doing work.

Energy is a derived quantity; meaning that it is obtained from the combination of fundamental quantities.

The unit of energy joules.

Other examples of derived quantities just like energy too are:

  • Volume
  • Speed
  • Acceleration
  • Density.
  • Upthrust
  • Momentum
  • Momentum
  • Power
  • Pressure
  • Force

Below are some few forms of energy; these are:

  • Kinetic energy
  • Potential energy
  • Mechanical energy
  • Solar energy
  • Light energy
  • Chemical energy

So therefore, the option which accurately defines kinetic energy from the choices above is:

the energy an object has because of its motion

zhannawk [14.2K]
Since they both have the same momentum, the object with the larger mass has a small velocity. (Remember that mass and velocity are inversely proportional with
p=mv.) Therefore, the smaller object will have the larger KE. (KE = 1/2 ^2)
