Answer:Temperature affects storage time and food deteriorates faster at higher temperatures. Microorganisms grow rapidly at room temperature . Thus to slow microbial growth, enzymatic and oxidative processes, food must be stored at room temperature.
Due to decomposition reactions with oxygen or carbon dioxide in the air, meat begins to feel slimy and smell spoiled. ... Because of its smaller surface area, the unsliced meat would have less collisions and therefore, a slower reaction rate.
Explanation:
Answer:
Isotopes
Explanation:
Isotopes are the same element with different masses because of the different number of neutrons. Also, the element doesn't change. If we change the protons, the element will change and then it won't be an isotope. Hope it helps!
I would say your answer is C, or the last one. Hope it helps
Explanation:
A property which causes change in chemical composition of a substance is known as a chemical property. For example, reactivity, toxicity, combustion etc.
Whereas a property which causes no change in chemical composition of a substance is known as a physical property. For example, mass, volume, density etc.
Sodium is a very reactive metal and it reacts readily with oxygen, water etc. So, when sodium is added to water then occurrence of an orange flame represents its reactivity.
Thus, based on given observation it can be concluded that chemical reaction takes place when sodium is added to water.
