8 0

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.

Note the mass of copper(1) oxide formula unit 143.091 what is the mass of 8.250 moles of Cu2O
baherus [9]

Answer:

The mass of 8.250 moles of Cu2O is 1180.5g

Explanation:

HOW TO CALCULATE MASS OF A SUBSTANCE:

  • The mass of a substance can be calculated by multiplying the number of moles in the substance by its molar mass as follows:

Mass (g) = no. of moles (mol) × molar mass (g/mol)

  • Molar mass of copper (I) oxide (Cu2O) = 63.5(2) + 16 = 143.09 g/mol

Mass of Cu2O = 8.250 mol × 143.09 g/mol

Mass of Cu2O = 1180.5 g

Therefore, the mass of 8.250 moles of Cu2O is 1180.5 g.

A medicine is given 73 grains ap/lbs. of patient per dose. The patient weighs 65.7 kilograms. how many drams ap should the apoth
erastova [34]

10,573.4

Explanation:

Given parameters:

Dosage per patient = 73ap/lbs

Weight of patient = 65.7kg

Unknown:

Amount of grams/ap to be given to the patient;

 

Solution:

Since our final answer should be expressed in grams, let us convert all units into grams.

   1000g = 1kg

 Converting 65.7kg to g = 65.7 x 1000 = 65700g

73ap/lbs;

      1lb = 453.6g

 73ap/lbs x \frac{1lb}{453.6g} = 0.161ap/g

Now,

 For a 65700g person, the number of grains app required;

      65700 x 0.161 = 10,573.4grains ap per dose

Alkali metals are found in many common substances but are rarely found in pure form. Explain why this is in the case
Evgesh-ka [11]

Alkali metals are rarely found in pure form because they are so reactive.

Alkali metals are in Group 1 of the Periodic Table.

They need to lose only one valence electron to reach a filled valence shell

Thus, they readily react wirh water and other chemicals in the earth to form compounds.
