You want to make a bracelet and have two materials: gold and silver. The bracelet needs to be eight inches long. You want to use
Misha Larkins [42]

Answer:

I'm going to call the length of the bracelet the number of times you have to add to get back to the first bead. This is the same as the number of beads, except in one case:

The shortest bracelet has length 1 and starts with (0,0). If you add one time, you get back to the first 0. But the bracelet has two beads. (Every bracelet has to have at least two beads to start.) The next shortest bracelet starts with (0,5), and has length 3: 0 5 5.

There is a bracelet of length 4 that starts with (2,6) (the first example on the main page):

2 6 8 4

There is a bracelet of length 12 that starts with (1,3) (the second example on the main page):

1 3 4 7 1 8 9 7 6 3 9 2

There is a bracelet of length 20 that starts with (0,4)

0 4 4 8 2 0 2 2 4 6 0 6 6 2 8 0 8 8 6 4

There is a bracelet of length 60 that starts with (0,1)

There are islands in the ocean that grow larger the Hawaiian islands are good examples of this the reason that the islands were
vredina [299]

Explanation:

The reasons that islands formed are still growing is simply because newer materials are being added to them.

  • A growing earth is as a result of addition of more materials arising from the mantle.
  • Generally, Volcanic islands forms as a result of magma that reaches the surface or ocean floor from deeper part of the earth.
  • This usually occurs in places around a plate boundary where materials upwells from the asthenosphere or shallow crustal melting.
  • As more materials are being melted, more also reaches the surface and continues to make the Island grow.

The law of conversion states that mass is never created or destroyed. Explain how this law requires all chemical equations to be
ikadub [295]

Answer:

See Explanation

Explanation:

The Law of Conservation of Matter as applied to chemical reactions says that matter is neither created nor distroyed, only changed in form. This implies that the mass of substances going into a reaction process must equal the mass of products generated during the reaction process.

Empirically,

∑ mass reactants = ∑ mass products

One can test this idea after balancing a chemical equation by determining the sum of formula weights of reactants and products; then compare. If reaction was properly balanced, the total mass reactants = total mass of products.

Example:

Combustion of Methane =>  CH₄(g) + 2O₂(g)   =>  CO₂(g) + 2H₂O(l)

Equation Weights =>             16amu + 64amu <=> 44amu +  36amu

Mass Reactants = Mass Products  => 80amu <=> 80amu.

*amu = atomic mass units => sum of atomic weights of elements
