Tammy spent of her savings on a watch. She then spent-of
the remainder on a

bag. What fraction of her money did she have left?

Answers

Answer:

1 / 2 of her money would be left

Explanation:

Tammy spent 2/5 of her savings on a watch. She then spent 1/6 of the remainder on a bag. What fraction of her money did she have left?

Taking the question bits by bit;

Tammy spent 2/5 of her savings on a watch

Amount Spent = 2/5

Remainder = 1 - 2/5 = 3/5

She then spent 1/6 of the remainder on a bag

Amount Spent = 1/6  *  3/5 = 1/2  *  1/5  = 1 /10

Total amount spent = 2/5 + 1 /10 =   (4 + 1 ) / 10 = 5 / 10 = 1 / 2

Amount left = 1 - 1 /2 = 1 / 2

Explanation:

Answer:-
Medium in which the sound waves are travelling.

Explanation:-
To understand this first we need to know that there are 2 types of waves; Mechanical waves and Electromagnetic waves.
Sound waves are mechanical waves meaning they need a medium to propagate. So this clarifies that they will obviously depend on the properties of the medium.
As far as the topic of speed is concerned;
sound travels fastest in solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster.

Answer:

B.

Explanation:

Minerals are formed due to chemical composition by rocks are pressured into their formed from dirt and naturally hard things.

The statement that represents a distinguishing difference between rocks and minerals is as follows:

Minerals have specific chemical compositions, but rocks do not.

Thus, the correct option for this question is B.

What is the difference between rocks and minerals?

A mineral is a naturally occurring substance with distinctive chemical and physical properties, composition, and atomic structure. Rocks are generally made up of two or more minerals, mixed up through geological processes.

Minerals are definitely formed due to chemical composition by rocks being pressured into their formation from dirt and naturally hard things. A rock is an inorganic and a solid naturally-formed substance without any chemical composition or atomic structure.

A mineral is also a solid, inorganic, substance as that like a rock which has a definite crystalline structure as well as chemical composition. Rocks form, break down and move through the rock cycle.

Therefore, the correct option for this question is B.

6. El oxígeno gaseoso se calienta a presión constate de 50 °C a 300 K. Se conoce que inicialmente el volumen del sistema era de 1,3 litros. ¿Cuál es el volumen final del sistema?

Answers

Answer:

El volumen final del sistema es 1.2L

Explanation:

La ley de Charles establece que el incremento de la temperatura de un gas produce un incremento en el volumen directamente proporcional cuando la presión permanece constante. La ecuación es:

V₁/T₁ = V₂/T₂

Donde V es volumen y T temperatura absoluta de un gas en 1, el estado inicial y 2, su estado final.

Reemplazando:

V₁ = 1.3L

T₁ = 50°C + 273.15K = 323.15K

V₂ = Incógnita

T₂ = 300K

1.3L/323.15K = V₂/300K

1.2L = V₂

El volumen final del sistema es 1.2L

Answers

Answer:

Most atoms do not have eight electrons in their valence electron shell. Some atoms have only a few electrons in their outer shell, while some atoms lack only one or two electrons to have an octet. In cases where an atom has three or fewer valence electrons, the atom may lose those valence electrons quite easily until what remains is a lower shell that contains an octet. Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic

1. Describe an experiment to show the chemical effect of electric current.
2. State three conditions necessary for combustion
3. Describe all that you observe when a piece of iron is placed in copper sulphate solution for a
few minutes.​

Answers

Explanation:

STEP 1- Take two iron nails.

STEP 2- Clean it with sand paper.

STEP 3- Wrap copper wire around both the nails. And connect the other end to the battery terminal.

STEP 4- Take water in beaker and little amount of salt in it or a few drpos of sulphuric acid in it.

STEP 5- Immerse the nails in the solution.

STEP 6- Observe the nails carefully. You can see bubbles of gases coming out from water near nails.

When, electeric current is passed through water gases like hydrogen and oxygen are evolved.

2.Three things are required in proper combination before ignition and combustion can take place---Heat, Oxygen and Fuel. There must be Fuel to burn. There must be Air to supply oxygen. There must be Heat (ignition temperature) to start and continue the combustion process.

When iron is placed in Copper sulphate solution, the iron is coated with a brown coloured substance "copper" and CuSo4 solution changes from blue to light green. This is due to iron displaces copper as it is more reactive than copper.
