Answers

Answer:

1:2

Explanation:

For every 4 moles of aluminum, there are 2 moles of aluminum oxide, so the mole ratio when converting from aluminum to alunmimum oxide is

2 moles aluminum oxide:4 moles aluminum. This can be simplified to 1:2.

Which of the following is a physical
change?
A iron rusting under water
B copper turning green in the air
C solid iodine subliming into a gas
D hydrogen and oxygen producing water

Answers

Answer:

C. solid iodine subliming into a gas

Explanation:

A physical change is a change that is reversible and can be reversed back into the original product. The atoms and molecules undergoes some rearrangement in the physical change. The process of change in the state of matters are placed under physical change. Solid iodine sublimes into purple gas on heating. The gas is then changed back to iodine crystals after being cooled. Hence, this is an example of a physical change.

is the study of matter and energy ,and the interactions between the two through forces and motion​

Answers

Physics is a study of matter, it’s motion and behavior and the related entities of energy and force.

The study of matter and energy ,and the interactions between the two  is through forces and motion​ which is a part of physics.

What is motion?

Motion is defined as a phenomenon which is described with respect to change in object's position with respect to time.It is given in terms of displacement,velocity,distance ,acceleration,speed.

Branch of physics which deals with motion of objects without any reference to it's cause is called kinematics while the branch which studies forces and their effects on motion is called as dynamics.

Motion applies to various systems like objects,bodies, matter particles ,radiation ,curvature.There are three laws of motion which are proposed by Newton.Classical mechanics is based on Newton's law of motion.Relativistic  mechanics is based on modern kinematics.

c. physical property.
b. extensive property.
d. chemical change.

Answers

Answer:

d

Explanation:

The measurement of boiling point is a physical property it involves only physical changes and not any chemical change. Hence, option c is correct.

What is physical properties?

Physical properties of a substance include properties such as boiling point, melting point, density, mass, solubility etc. These are all characterised with a change in physical state of the substance and not any chemical reactions.

Boiling point of a substance is the temperature at which the substance converts from its liquid state to vapor state where the vapor pressure of the gas phase above the liquid is equal to the atmospheric pressure.

Boiling of a substance does not involve any making or breaking of chemical bonds and not producing a new compound. Therefore, boiling point is a physical property.

Answer:

when the forest burns all the trees die and the ground becomes more fertile.

The mass of forest trees is due primarily due to the presence of carbon in them. When the forest burns the mass is not destroyed as burning does not cause changes in matter.

What is the law of conservation of mass?

Law of conservation of mass is a law which states that during a chemical reaction mass is neither created nor destroyed.Rather it is the only form of the matter which changes.

In chemistry, the law of conservation of mass can be  stated as during a chemical reaction the mass of products is always equal to the mass of the reactants.

This law is important in chemistry as it helped scientists to understand that during a chemical reaction substances do not disappear rather they are transformed to new substances of equal mass.

Law of conservation of mass was given in the year 1774 by French chemist Antoine Lavoisier and hence is also known as Lavoisier's law.

Extensive properties _______________ useful for identifying a substance because the substance may be present in any _______________. Some _______________ properties, such as _______________, aren't useful either.

Answers

Answer: Extensive properties such as the mass, volume and entropy of systems are additive for subsystems, useful for identifying a substance because the substance may be present in any physical properties. Some intensive properties, such as temperature, refractive index and density, aren't useful either.

Explanation: According to scientific studies, Physical properties of materials and systems can often be classified as being either intensive or extensive, according to how the property changes when the size (or extent) of the system changes. Based on IUPAC classification, an intensive quantity is one whose magnitude is independent of the size of the system whereas an extensive quantity is one whose magnitude is additive for subsystems. This explains the corresponding mathematical ideas of mean and measure, respectively.

Round 2.6765 to two significant figures

Answers

Answer:

2.7 Significant Figures

Explanation:

The two significant figure value is "2.7".

Significant figures:

Users were required to round up the given value, 2.6765, to two significant numbers in this challenge. Since the given number has no zeroes, all the digits are significant. Therefore, if we need and round the given number to 2 major digits, the number should only have two numbers.

Then we must select if the last digit to be preserved will be scaled up or down, and this will be determined either by digit following the last digit to be retained.Whereas if the digit after the last digit to be kept is greater than 5, the last digit should be rounded up.A digit following the last digit to be kept in the supplied number is 7, which is more than 5, hence using the aforementioned concept, So, the round figure value is "2.7".

Therefore, the round figure value is "2.7".

You are throwing a pizza party for 15 people and figure that each person will eat 4 slices. You call the pizza place and learn that each pizza will cost you $14.75 and it will be cut into 12 slices. How much is the pizza for this party going to cost you? Give the answer to the nearest cent.

Answers

Answer:

15 people x 4 slices so you’ll need 60 pieces

60/12(the amount of slices per pizza) =5

You need 5 pizzas. $14.78 x 5 = 73.90.

Explanation:

the answer is that one 73.90 is rounded nearest cent : ) took me a while to get it

Answer:

the cost of pizza for 15 people is $73.9

Explanation:

a pizza party for 15 and each person will eat 4 slices.

meaning the 15 people will eat 4 x 15 = 60 slices

Since each pizza will cost you $14.78 and will be cut into 12 slices.

`1 pizza = 12 slices = $ 14.78

60 slices = (14.78 x 60) / 12  = 886.8 /12 = $73.9the cost of pizza for 15 people is $73.9
