Answer:
Explanation:
C6H12O6 is the formula of simple sugar, glucose. The primary elements in the glucose are carbon, hydrogen and oxygen. Thus, glucose belongs to the group of carbohydrate.
Carbohydrates are group of bio molecules that comprises of carbon , hydrogen and oxygen as its constituents elements. Thus all the substances that contain all three element primarily C, H and O are considered as carbohydrates.
A statement from the laboratory report which best represents a conclusion for this investigation is that: D. students who spend less time studying after school get lower math grade.
<h3>What is a research?</h3>
A research is also referred to a study and it can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause), in order to determine or measure the dependent variable (the effect) and reach a logical conclusion with results.
<h3>What is an analytical research report?</h3>
An analytical research report can be defined as a well-crafted and written document that is typically used by a researcher to display a detailed analysis of the information which are obtained through a particular research method.
In this scenario, we can infer and logically deduce that a statement from the laboratory report which best represents a conclusion for this investigation is that the group of students who spend less time studying after school would get lower math grade.

Answer:
Scientists have been debating over light being a wave or particle since its recognition.
Sir Issac Newton discovered that light had frequency and other properties. Newton described light to be a particle because it created shadows which were sharp and very clear.
Francesco Maria Grimaldi, claimed that light was a wave. This was because this scientist observed the diffraction of light and hence, claimed light to be a type of wave.
The speed of light is 299 792 458 m / s. Nothing can travel faster than light.
True
Explanation:
Ionic compounds are chemical compounds that dissociates into positive and negative ions and are globally neutral due to the charge balance. They are made up of metals and non-metals.
- Ionic bonds are formed between two kinds of atoms having a large electronegativity difference.
- It is usually between metals and non-metals.
- The formation of this bond type involves the transfer of electrons from the less electronegative atom such that the two kinds of atoms now have completely filled outer shell like the noble gases.
- This transfer makes the metal positively charged while the non-metal becomes negatively charged.
- The atoms forms ions that are oppositely charged.
- The charges are balanced out leaving a net neutral compound.
- The electrostatic force of attraction between these ions is the ionic or electrovalent bond.
