which terms are used to identify pure substance

Answers

Answer:

Physical properties of a substance are characteristics that can be observed without altering the identity of the substance. Color, odor, density, melting temperature, boiling temperature, and solubility are examples of physical properties. Physical properties can be used to identify a pure substance.

Explanation:

Answers

Answer:

First change cm in m and mass is 38.6g. Volume. =200m

Explanation:

Now,

Density =mass /volume

38.6/200

0.193 density

If the value of volume doubles but the mass stays
the same, the value for density will be
1.double
2.the same
3.halved

Answers

Answer:

halved

Explanation:

density decreases when volume increases if mass is kept constant density is defined as mass divided by volume.

If the value of volume doubles, but the mass stays the same, the value for density will be halved. The correct option is 3.

What are volume, mass, and density?

Density is the mass per unit volume. Density is a scalar quantity. It is denoted by d and the symbol for density is given as rho, a Greek symbol. Density is calculated as mass divided by volume.

Mass is the quantity of matter in a physical body. The product of the molar mass of the compound and the moles of the substance are defined as mass.

Volume is the space occupied by a three-dimensional object. Volume is calculated by dividing mass by density.

These three factors are related to each other. If two variables are given, the third can be calculated.

Thus, the correct option is 3. Halved.

emelie is working on a science project. her task is to answer the question does rogooti a hair cream sold on tv affect the speed of hair growth in length her family is willing to volunteer for the experiment

Answers

Answer:

This question is incomplete and unclear; the complete question including the missing part is:

Emelie is working on a science project. Her task is to answer the question:

"Does Rogooti (a hair cream sold on TV) affect the speed of hair growth

(in length)". Her family is willing to volunteer for the experiment. Identify the control group (CG) and the independent and dependent variables.

ANSWER:

Independent variable: Rogooti hair cream

Dependent variable: Speed of hair growth/length

Control group: Family members that do not use the Rogooti hair cream

Explanation:

In an experiment, the independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable response. In this case, the ROGOOTI HAIR CREAM is the independent variable.

Dependent variable refers to the variable that is measured or the variable that responds to the change made to the independent variable. In this case, the dependent variable is SPEED AT WHICH HAIR GROWS (IN LENGTH).

Control group in an experiment is the group that does not receive the experimental treatment. In this case, the experimental treatment is the Rogooti hair cream, hence, the control group will be the VOLUNTEER FAMILY MEMBERS THAT DOES NOT RECEIVE THE ROGOOTI HAIR CREAM ON THEIR HAIR.

If you know the volume and the density of an iron rod, how would you calculate the mass of that iron rod? Show a formula.

Answers

Answer: for an example

volume can easily be calculated: pi*(d^2/4)*length -> pi*[(7x10^-2)/4]*70x10–2 = volume of iron rod {VOIR}

Density = mass / volume

Therefore

Mass = density x volume

However, weight is equals to ‘mass x g (free fall acceleration’

So mass is in kg but weight is a force so simple force equation to where ‘a (acceleration)’ in ‘F=ma’ is ‘g’.

Hence,

Weight = 9.81 ms^-2 (is ‘g’) x 7870 kgm^-3 x VOIR m^3 is *insert calculated answer* N.

Why is the reactivity of metal increase but that of non-metal decreases as we go down in a group of periodic table? (pls its important i need this question's ans for my exam so answer it fast thank you)

Answers

Answer:

Nonmetal reactivity decreases down a group because the nucleus' ability to gain more valence electrons weakens due to more nuclear shielding. For Metals: the most reactive metals are those that can lose their valence electrons the most easily. ... Francium is the most reactive metal

Explanation:

Answer:

While moving from top to bottom in a group of the periodic table, the reactivity of non- metals decreases. ... Thus, the tendency of gaining electron/s in the valence shell decreases as well as the chemical reactivity also decreases on moving from top to bottom in a group of non- metals.

B. 0.0288 in./s
C. 1.14 in./s
D. 2.64 in./s

Answers

Answer:

1.73 meters / minute = 1.14 inches / second

Explanation:

The number of inches present in 1.73 meters/minutes is equal to 1.14 inches/seconds.

What is conversion factor?

Conversion factor is a quantity which is get multiplied or divided with an any other given quantity to convert the given quantity into any other quantity.

Given quantity = 1.73 m/min

We know that, 1 meter = 39.37 inches

1.73 m/min = 1.73 × 39.37 = 68.11 inches/min

Also we know that, 1 min = 60 min to convert the above quantity into sec we should divide that by 60 as:

68.11 inches/min = 68.11 / 60 = 1.135 inches/sec (1.14)

Hence the required quantity is 1.14 in./s.

Draw the electric field lines between a proton and an electron. According to Coulomb's law, how would the electrical force between these particles change if the product of their electrical charge increased?

Answers

Explanation:

An electron has a negative charge and a proton is a positively charged particle. Electric field lines are used to express the direction of the electric field. For a positive charge, it is outwards while for a negative charge it is inwards. The attached figure shows the electric field lines between a proton and an electron. The field lines emerge from proton and terminate at electron.

The electrical force between charges is given by :

[tex]F=k\dfrac{q_1q_2}{r^2}[/tex]

r is the distance between charges

The force is directly proportional to the product of charges. It means that if the product of electrical charge increased, it means that the electrical force will increase proportionally.
