A mixture cannot be reversed back to it’s original properties (true or false)
Answers
Answer:
False
Explanation:
A mixture is composed of two or more substances that are combined through physical means. It has NOT undergo any changes in its chemical properties. So, even though its appearance change, it can be reverted back.
Answer:
That answer would be false.
Explanation:
Depending on the type of mixture, you can separate it and reverse it back to its original properties through filtration, evaporation, distillation, and chromatography.
colonel flanders makes boxes of chicken with various numbers of pieces. He charges $ 0.40 for each piece of chicken, plus a fixed charge of $ 0.55 for the box, the rolls, etc. If Iddy Ottic bought the $6.95 box, how many piecesof chicken should the box contain?
Answers
Subtract 0.55 from 6.95 and you get 6.40
The divide 6.40 by 0.40 and you get 16

new virus
Answers
Answer:
D. A federal government agency publishes an article in a professional scientific journal detailing technical details of a new virus.
Explanation:
Public scientific communication is a way used by scientists to make the audience able to understand the basics of science to communicate an informed decision. There are several skills under public scientific communication that include connect with the public, talk to journalists, make science understandable, and understand the audience.
The best way to connect with the audience is to publish an article in a professional scientific journal because mostly journals are peer-reviewed having standard of quality.
A federal government agency informing about a new virus through an article in a professional scientific journal is the best way of public scientific communication as it will be for a specific audience along with a standard of quality.
Hence, the correct answer is "D".

An echolocation refers to a method that relies on sound waves and is used by different animal species for navigation, communication, and finding food. Therefore, option A is correct.
What is an echolocation ?Echolocation is a method used by bats, dolphins, and other animals to locate objects using reflected sound. This enables the animals to move around in complete darkness, allowing them to navigate, hunt, recognize friends and enemies, and avoid obstacles.
(1) To hunt for prey, bats make high-frequency sounds. (2) Sound waves are used by dolphins and other toothed whales to locate prey and navigate their surroundings. (3) Nocturnal oil birds use echolocation to navigate their surroundings, particularly in low-light conditions.
Echolocation is used to help with orientation, obstacle avoidance, food acquisition, and social interactions.
Thus, option A is correct.

A sample contain 33.42g of metal pellets are poured on to a graduated cylinder initially containing 12.7ml of water, causing the water level to rise to 21.6ml. Calculate the density of the metal
Answers
Answer:
3. 76 g/ml^3
Explanation:
We are given the mass of the metal pellets which is 33.4 grams. To calculate the density of the metal, we need to divide the mass by the volume. The volume of the metal is not directly given so we need to find it ourselves. The water was initially 12.7 ml and then it rose to 21.6 ml after placing the metal pellets. This indicate that the volume of the metal pellets is 8.9 ml.
[tex]21.6 - 12.7 = 8.9[/tex]
We can now use the density formula.
[tex]p = \frac{m}{v} [/tex]
[tex]p = \frac{33.42}{8.9} [/tex]
[tex]p = 3.76[/tex]
The density of the metal is equal to 3.76 g/ml.
What is the density?The density of an object can be defined as the mass per unit volume. The average density is equal to the total mass of the object divided by the total volume of the object.
The mathematical formula for the density of the material is expressed as follows:
Density = Mass/Volume
The S.I. unit of the density is Kg/m³ and is an intrinsic property as it is independent of the size. If the size increases, the mass increases as well but the density of the material remains constant.
Given the mass of the metal, m = 33.42 g
Volume of the metal = Volume of water level with metal - volume of water
V = 21.6 -12.7 = 8.9 ml
The density of metal = 33.42/8.9 = 3.76 g/ml
Therefore, the density of the metal is 3.76 g/ml

(4.1357 x 10^-15) x (5.4 x 10^2) Answer must be in scientific notation
Answers
Answer:
22×10⁻¹³
Explanation:
Scientific notation:
Scientific notation is the way to express the large value in short form.
The number in scientific notation have two parts.
The digits (decimal point will place after first digit)
× 10 ( the power which put the decimal point where it should be)
for example the number 6324.4 in scientific notation will be written as = 6.3244 × 10³
When we multiply or divide the values the number of significant figures must be equal to the less number of significant figures in given value. Thus, in given value,
(4.1357× 10⁻¹⁵) × (5.4×10²)
22×10⁻¹³

An object has 15 grams of atoms and displaces 2.5 mL of water when dropped into a cylinder. What is the objects density... HELP IM IN CLASS RN AND I NEED ANSWERS ASAP, grades are due in couple hours
Answers
Answer:
6g/mL
Explanation:
The density, which is the mass per unit volume of an object, can be calculated using the formula;
D= m/v
Where; D = density (g/mL)
M = mass of substance (g)
V = volume (mL)
In this question, the object's mass = 15g, volume of water= 2.5 mL, d =?
Therefore,
Density = 15/2.5
Density = 6 g/mL
The object's density is 6g/mL

Answer:
Arsenic if I understood correctly
Explanation:
Ions can be made by single element or covalently bonded group of elements. The covalently bonded group of elements is called polyatomic ions or polyatomic atoms. Therefore, the element with atomic number 33 and -3 charge is Arsenic.
What is Ions?Any species that contain charge whether it is positive charge or negative charge is called ions. The example of polyatomic ions are sulfate, phosphate, nitrate etc.
Cation is the species that loose electron and attain positive charge while anion is a species which gain electron and attains negative charge so when anion and cation combine in fixed ration the the overall charge of the molecule is zero that is molecule is neutral, the charge over cation and anion is also called oxidation state. The element with atomic number 33 and -3 charge is Arsenic.
Therefore, the element with atomic number 33 and -3 charge is Arsenic.

Pioneer species like Lichens and Mosses inhabit an area after a major disturbance, such as a volcanic eruption. Over time, other species are found in the disturbed areas, and the number of pioneer species decreases. Why does the number of pioneer species get less?
Answers
Answer:
The number of pioneer species get less as the area has more soil to support complex plants and the competition decreases the role of pioneer species.
