what ions are produced when salt is dissolved in water
Answer:
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.

Based on the results of this lab, write a short paragraph that summarizes how to distinguish physical changes from chemical changes. Physical changes occur when the properties of a substance are retained and/or the materials can be recovered after the change. Chemical changes involve the formation of a new substance.
Answer:
Physical changes occur when the properties of a substance are retained and/or the materials can be recovered after the change. Chemical changes involve the formation of a new substance. Formation of a gas, solid, light, or heat are possible evidence of chemical change.

Kendall has an empty graduated cylinder with markings and an identical graduated cylinder partway filled with water. She also has a balance and a marble
Answer:
She can measure the volume and mass of the marble, the volume and mass of the water, and the mass of the graduated cylinder.
Explanation:
Graduated cylinders are used to measure volume, hence she can be able to measure the volume of the marble from the volume of water displaced. The measuring cylinder is also used to measure the volume of the water. The balance is used to measure the mass of the water and mass of the marble.
Identify the control group and the independent and dependent variables in the following
scenario: 300 chickens are divided into three equal sized groups. Group A is injected weekly
with 10 mg of a growth hormone. Group B is injected weekly with 25 mg of the growth
hormone. Group C is not given any growth hormone. All 300 chickens are weighed after again
after 3 months.
The control group is II
The independent variable is
The dependent variable is
« Previous
Answer:
The controls group = group c
Independent variable = number of mg with respect of growth hormone
Dependent variable = Chicken growth
Explanation:
According to the given situation, the controls group represents the group C. The independent variable shows the number of mg of the hormone growth
And, the dependent variable depicts the growth of a chicken
Also, in the contract group, there is nothing for addition
And, the chicken growth would be depended upon the hormonal growth

In any pure sample of CO2, the ratio of the mass of carbon to the mass of
oxygen is always the same. You can justify this ratio by the fact that
compounds are composed of which of the following?
A. Identical molecules created from atoms combined in whole
number ratios
B. Atoms whose chemical properties do not change during a
chemical reaction
O C. Atoms whose masses do not change during a chemical reaction
D. Different molecules which together produce the observed
elemental ratios
Answer:A
Explanation:por q si bb
Identical molecules created from atoms combined in whole number ratios this is the best justification for In any pure sample of CO2, the ratio of the mass of carbon to the mass of oxygen is always the same.
What ratio of Mass of Oxygen and Carbon?Consider the elements carbon and oxygen. Combined in one way, they form the familiar compound carbon dioxide. In every sample of carbon dioxide, there are 32.0g of oxygen present for every 12.0g of carbon. By dividing 32.0 by 12.0, this simplifies to a mass ratio of oxygen to carbon of 2.66 to 1.Carbon has an atomic weight of 12, oxygen in diatomic form(O2) of 32 and CO2 of 44. This means that the mass of 6x1023 atoms of CARBON has a mass of 6 kilograms, the mass of 6x1023 diatomic oxygen molecules is 32 kg, and for CO2 it is 44kg. So carbon is the lightest and CO2 the heaviest.Identical molecules created from atoms combined in whole number ratios this is the best justification for In any pure sample of CO2, the ratio of the mass of carbon to the mass of oxygen is always the same.

The Rydberg constant is 3.3 x 10 15 Hz. this value is also
Answer:
Rydberg constant 3.3 x 10¹⁵ Hertz is equal to 1.090 x 10⁷ m⁻¹
Explanation:
Given;
Rydberg constant as 3.3 x 10¹⁵ Hz
1 Rydberg constant = 3.3 x 10¹⁵ Hz
1 Rydberg constant = 1.090 x 10⁷ m⁻¹
Therefore, Rydberg constant 3.3 x 10¹⁵ Hertz is equal to 1.090 x 10⁷ m⁻¹
Here, we are required to identify another value for the Rydberg constant part from 3.3 × 10¹⁵Hz.
This value is also R = 1.1 × 10⁷.
The Rydberg constant, R is a constant relating to the electromagnetic spectra of an atom.
The value of Rydberg constant is 3.3 x 10¹⁵Hz above and is in terms of the Frequency of the spectra lines.
However, another way to express Rydberg constant is by dividing its value above by the speed of light, c to yield;
R = R'/c where c = speed of light = 3 × 10⁸m/s.This Rydberg value is also, R = (3.3 × 10¹⁵)/3×10⁸.
Therefore, this value is also R = 1.1 × 10⁷.

What makes a question testable? Can someone help me on this pls it has to be either a 4-5 sentence! this is a science question.
Answer:
testable questions are answer through observation or an experiment that provides evidence that the questions connects to the scientific concepts rather the opinion feelings
therefore the question can be tested through observation or experiment
What does it mean for a hypothesis to be testable? APEX
Answer:
A Scientific hypothesis must be testable, for a hypothesis to be testable means that it is possible to make observations that agree or disagree with it. This statement may or may not be true, but it is not a scientific hypothesis. That's because it can't be tested.

Which is a postulate of the kinetic-molecular theory?
O Gas particles have a small volume relative to the spaces between them.
Gas particles have a large volume relative to the spaces between them.
Gas particles are very small in size and always move slowly.
O Gas particles are very large in size and always move slowly.
Answer:
Gas particles have a small volume relative to the spaces between them.
Explanation:
i just took the quiz.
Gas particles have a small volume relative to the spaces between them is the postulate of the kinetic molecular theory.
What is kinetic molecular theory?The kinetic molecular theory describes about the behaviour of ideal gases at the particle level.
The five main postulates of the kinetic molecular theory are as follows:
1) The particles in a gas are in constant and random motion
2) The combined volume of the particles is negligible.
3) The particles exert no forces on one another.
4) The collisions between the particles are completely elastic.
5) The average kinetic energy of the particles are proportional to the temperature in kelvin.
Hence, we can conclude that option 1 is the answer.

When an object has a definite
shape, how is it measured? Give an
example of an object and the tool
you would use to measure it.
Explanation:
Mass is the amount of matter in an object. Mass is measured in grams (1000 grams = 1 kilogram). 2. Solid- The particles of matter in a solid are tightly packed together and have a definite shape and take up a definite amount of space (volume).
for example and apple you can use a scale to find the mass. or a graduated cylinder to find the volume
