Answer:

Conserved.

Explanation:

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

Momentum = Mass * Velocity

The law of conservation of momentum states that the total linear momentum of any closed system would always remain constant with respect to time.

This ultimately implies that, the law of conservation of momentum states that if objects exert forces only on each other, their total momentum is conserved.

Which element has the highest first electron affinity? which element has the highest first electron affinity? te ba xe cs?
Savatey [412]
Electron affinity is the energy released when an electron is added to the gaseous atom or ion.
Electron affinity increases by moving from left to right in periodic table and decreases by moving from up to down.
So the correct answer is Te
Xe: being as noble gas it is unacceptable to gain an electron
The values of electron affinity for these elements:
Ba (13.9 kJ/mol) - Te (190.1 kJ/mol) - Xe (-80 kJ/mol) - Cs (45.5 kJ/mol)

In the lab you weigh out 76.02 g of Iron (Fe). How many moles of Iron do you have in the sample. (Your answer must have a unit..
son4ous [18]

Answer:

We have 1.361 moles in the sample

Explanation:

Mass of iron = 76.02g

Molar mass of iron = 55.845 g/ mole ( This we can find in the periodic table, and menas that 1 mole of iron has a mass of 55.845 g).

To calculate the number of moles we will use following formula:

moles (n) = mass / molar mass

moles iron = 76.02g / 55.845 g/ mole

moles iron = 1.36127 moles

To use the correct number of significant digits we use the following rule for multiplication and division :

⇒ the number with the least number of significant figures decides the number of significant digits.

⇒76.02 has 4 digits ( 2 after the comma) and 55.845 has 5 digits (3 after the comma).

⇒ this means 1.361 moles

We have 1.361 moles in the sample
