Answer:
Answer: Boiling water has a lot more heat than the oven's air (even though the air has a higher temperature). ... The iceberg has more heat than the match because it is SO MUCH LARGER, so all of its slow moving molecules have more total kinetic energy than the match's molecules.
Explanation: I got this from google, and hope it helps, if not, comment below please!!!
Explanation:
Percentage composition tells you the percentage of each element present in a compound or molecule. This allows you to work out the number of atoms of each element present in the molecule. Percent composition is important because it allows us to determine the percentage of each element that makes up a specific compound. Percent composition is important because it allows us to determine the percentage of each element that makes up a specific compound.
Answer:
It tells you what the substance is made of.

Answer:
See below.
Explanation:
The mass of octane in the sample of gasoline is 0.02851 * 482.6 = 13.759 g of octane.
The balanced equation is:
2C8H18(l) + 25O2(g) ----> 16CO2(g) + 18H2O(g)
From the equation, using atomic masses:
228.29 g of octane forms 704 g of CO2 and 324.3 g of H2O
So the mass of CO2 formed from the combustion of 13.759 g of octane = (704 * 13.759) / 228.29
= 42.43 g of CO2.
Amount of water = 324.3 * 13.759) / 228.29
= 19.55 g of H2O.

The initial ___________ energy is equal to zero because the starting point is set at zero height to make things easier.
kinetic
potential
3.
In the example, the final kinetic energy is determined to be ___________ because at the peak height, the ball instantaneously stops.
positive
zero
negative
4.
In this system, potential and kinetic energy are ________________ proportional.
inversely
directly
The system has an energy that can be conserved in the system, and when work is performed, the energy has been converted to working energy.
The following sentences can be completed as:
Total energy = Potential energy + Kinetic energy

Answer:
1)total, 2)potential, 3)zero, 4)inversely.
Explanation:
1) The total energy in a mechanical system is determined by adding the potential and kinetic energy together.
2) The initial potential energy is equal to zero because the starting point is set at zero height to make things easier.
3) In the example, the final kinetic energy is determined to be zero because at the peak height, the ball instantaneously stops.
4) In this system, potential and kinetic energy are inversely proportional.
Answer:
Mass, m = 30 grams
Explanation:
It is given that,
Density of an object,
Volume occupies by the silver,
We need to find the mass of a piece of silver. The mathematical formula for the density is given by :
m = 30 grams
So, the mass of the piece of the silver is 30 grams. Hence, this is the required solution.
The density of a Material
The density of a material is defined as the mass per unit volume
it formula is given as
Density = Mass/Volume
and the unit is g/cm^3
Explanation:
Given data
Mass = ???
Volume = 10mL
Density = 3g/ml
Hence the mass is expressed as
Mass= density /Volume
Mass= 3/10
Mass= 0.3g
Therefore the Mass is 0.3g
