What else can I help you with?
Is it True or false that compounds and mixtures be synthetic or natural?
True. Compounds and mixtures can be either synthetic or natural. Synthetic compounds are created by humans in a laboratory while natural compounds are found in nature. Similarly, mixtures can also be either synthetic or natural based on their origin.
The main reason for learning to correctly pour fluids in a laboratory is to conserve costly chemicals. true or false?
True. Correctly pouring fluids in a laboratory helps to prevent spillage and waste of costly chemicals, thereby conserving resources and reducing costs.
The main reason for learning to correctly pour fluids in a laboratory is to conserve costly chemicals true or fasle?
False. The main reason for learning to correctly pour fluids in a laboratory is to ensure accurate measurements and reproducible results in experiments, not necessarily to conserve costly chemicals. Proper pouring techniques also help maintain a safe working environment by preventing spills or exposure to hazardous substances.
The gases on titan are all ionically bonded true or false?
False. The gases on Titan are primarily molecular gases such as nitrogen and methane, which are not ionically bonded.
Molecules never arrange themselves in the same way True or False?
False. Molecules can arrange themselves in the same way under specific conditions, resulting in the formation of structures with repeating patterns (e.g. crystals).
CFCs are the catalyst in the destruction of Ozone. true or false?
CFC's are catalysts. They fasten the rate of reaction.
Is this statement true or false Saliva contains chemicals that help kill pathogens?
true
True or false the analytic phase of Cubism was notable for the use of the collage method?
It is false. Collage is in synthetic Cubism.
The acidopore on a crazy ant is used to excrete chemicals for defense and attack. True or False?
true
True or false a main cause of the thinning of the ozone layer is global warming?
False. The main cause of the thinning of the ozone layer is the presence of halogen atoms in the stratosphere from man-madeHalocarbon refrigerants (CFCs, freons, halons).
Is it True or false that compounds and mixtures be synthetic or natural?
True. Compounds and mixtures can be either synthetic or natural. Synthetic compounds are created by humans in a laboratory while natural compounds are found in nature. Similarly, mixtures can also be either synthetic or natural based on their origin.
When two chemicals are mixed and the breaker gets warm it usually indicates that a chemical reaction has taken true or false?
true
when There is no requirement to take action to identify and discipline those responsible for the unauthorized disclosure of Controlled Unclassified Information?
False
What is the result of True AND False OR True?
True AND False OR True evaluates to True. IT seems like it does not matter which is evaluated first as: (True AND False) OR True = False OR True = True True AND (False OR True) = True AND True = True But, it does matter as with False AND False OR True: (False AND False) OR True = False OR True = True False AND (False OR True) = False AND True = False and True OR False AND False: (True OR False) AND False = True AND False = False True OR (False AND False) = True OR False = True Evaluated left to right gives a different answer if the operators are reversed (as can be seen above), so AND and OR need an order of evaluation. AND can be replaced by multiply, OR by add, and BODMAS says multiply is evaluated before add; thus AND should be evaluated before OR - the C programming language follows this convention. This makes the original question: True AND False OR True = (True AND False) OR True = False OR True = True
The cell mechanism of active transport involves the transport of insoluble chemicals across the membrane with protein acting as the carrier. true or false?
true
Is it true that ozone is not depleting but there is a false warning about it?
No, it is not true that ozone is not depleting. Ozone depletion is a well-established scientific fact caused by the release of certain chemicals, such as chlorofluorocarbons (CFCs), into the atmosphere. This depletion has led to the formation of the ozone hole in some regions, particularly over the poles. The warnings about ozone depletion are based on extensive scientific research and observations.
( true or false ) All chemicals in the lab are to be considereddangerous?
All chemicals in the lab are to be considered dangerous. ... Laboratory work can be started immediately upon entering the laboratory even if the instructor is not yet present.
