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:
B. The data were reproduced by other scientists using the same experimental methods.
Explanation:
One of the features of reliable experimental results is their reproducibility — other scientists must be able to produce them.
A. is wrong. An experiment that is designed to prove a hypothesis is biased.
C. is wrong. A conclusion based on a single experiment is suggestive but not conclusive. It takes a number of experiments to provide a strong statistical relation between the variables.
D. is wrong. The data may support a conclusion that the they reached using logic and critical thinking, but there may still be a flaw in the thinking, which other scientists can point out.
Opposite charges on positive and negative ions attract each other.
Answer:
2 M
Explanation:
The equation for molarity is "M = moles/liters"
Potassium chloride's atomic mass is 74.55, meaning one mole of KCl is equal to 74.55g. In the equation, 298g of KCl is being used. To find out how many moles this is, multiply 298g of KCl by (1 mol/74.55g of KCl) to get 4.0 moles. Now you can use the equation for molarity.
M = 4.0 moles/2 Liters
Answer: 1s²2s²2p³ or it can also be 3s²2p³
