What else can I help you with?
What are two types of evidence that suggest that evolution has occurred?
The two types are Dna, and fossils
Why is a possible explanation for a set of observations called a hypothesis?
A hypothesis is your first guess at how something/ your experiment is going to turn out. If the results you get match your hypothesis you can declare that it provides evidence to suggest that your hypothesis is true.
What can you conclude from your observations?
Based on my observations, it appears that certain patterns or trends are emerging that indicate a significant relationship between the variables in question. These insights suggest potential areas for further investigation or analysis. Additionally, the consistency of the data points supports the reliability of the conclusions drawn. Overall, the findings highlight key implications that could inform future decisions or strategies.
How does helium impact human life?
Helium is a chemical if you breath that chemical through a balloon or anything that involves helium will shut your body off.Helium can be a very dangerous chemical Helium is an inert gas, and despite the fact that some inhale it to change their voice temporally, I don't suggest inhaling. You need gas exchange to live.
What are five qualities that scientist are good at?
The qualities of a good scientist vary according to their specialisation, but in general they need: - to be able to make observations on the things that they are studying - to be able to ask meaningful questions about the item they are studying - to be able to suggest answers to the questions that they ask - to be able to test their answers by making more observations. Good scientists should be able to be passionate about their ideas, but objective in how they view them. In other words, they should be willing to work hard to develop and test their ideas, but they have to be willing to let those ideas go if they are proven to be incorrect.
How do we know a chemical reaction has occurred?
A chemical reaction can be identified by several observable signs: the formation of a gas (bubbles), a change in color, the production of heat or light, and the formation of a precipitate (solid) from a liquid solution. Additionally, changes in properties such as odor or taste may indicate a reaction. These indicators suggest that the original substances have transformed into new substances with different chemical compositions.
What are the four ways to tell if a reaction has ofurred?
A reaction has occurred if there are observable changes such as a color change, the formation of a precipitate, the evolution of gas (bubbles), or a temperature change (either an increase or decrease). These indicators suggest that new substances have formed as a result of the chemical reaction. It's important to consider the context, as not all changes necessarily indicate a chemical reaction.
If new products are made in a chemical reaction what does that suggest about the reaction?
No new products can be made in a chemical reaction. Only the reactants exchange or react with another element.
What are clues that a chemical reaction has taken place A Formation of a gas B Constant temperature C Steam D Change in color?
A) Formation of a gas: Bubbles or fizzing can indicate the release of a gas during a chemical reaction. C) Steam: The presence of steam may indicate that water is being formed as a product of the reaction. D) Change in color: A noticeable change in color of the substances involved can suggest a chemical reaction has occurred.
Suggest 2 observations when Ca reacts with water?
The reaction is:Ca + 2 H2O = Ca(OH)2 + H2- hydrogen gas is released- the reaction occur at room temperature
A compound is added to a solution of hydrochloric acid and the solution is observed to see if a reaction takes place Chemical is being tested?
The reaction may indicate the presence of a metal compound that can react with hydrochloric acid to form a metal chloride and hydrogen gas. The observation of bubbling or fizzing would suggest a chemical reaction has occurred. Additional tests may be needed to identify the specific metal present in the compound.
Experimental observations suggest a gas is being released?
steam
Can you use a permanent marker as makeup?
Wouldn't suggest it. Permanent marker often contains chemical that aren't safe for the skin and may cause a reaction.
Suggest a chemical test(s) to distinguish ethanol and phenol. Include the reagents reaction conditions and observations. And the equation?
Phenol solution, or phenol directly from the manufacturer?If the phenol is in the form it comes in from the factory, no chemical test is necessary. Phenol is a white crystalline solid.If it's dissolved in water, the easiest test is pH. Phenol solution is more acidic than ethanol. So...whatever you use for a pH test will do ya.
Observations that are collected and which support or suggest a conclusion are known as?

How do recent observations suggest the universe will end?
