What is a glass rod used for in chemistry and biology laboratory?
Answers
Final answer:
A glass rod is used in chemistry and biology laboratories for transferring liquids, stirring solutions, and manipulating microscopic organisms.
Explanation:
A glass rod is commonly used in chemistry and biology laboratories for various purposes. In chemistry, it can be used to transfer small amounts of liquids from one container to another without contamination. It is also used for stirring solutions and facilitating chemical reactions. In biology, a glass rod can be used for extracting small samples or manipulating microscopic organisms in a controlled manner.

0.5 MOLES of sodium chloride is dissolved to make 0.05 liters of solution?
please help me with the grams. thank you (: first time using this!
Answers
=> 0.5 grams of Sodium chloride dissolved in 0.05 liters solution
=> 0.5 moles of sodium chloride dissolved in 0.05 liters solution
The answer is NO. They are not equal because 0.5 grams of sodium chloride is equivalent to 10 moles of sodium chloride which makes 0.5 grams of sodium chloride mixed with 0.05 liters of solution more concentrated than 0.5 moles of sodium chloride dissolved in 0.05 liters of solution.

P is pressure (in atm or bar)
V is volume (in L)
n is the number of moles (in mol)
R is an experimentally determined ratio of about 0.82
T is the temperature (in Kelvin)
Note: For all gases, you need to convert Celsius or Fahrenheit to Kelvin.
Get V alone.
Plug in the values you have.

What is glucose ?
A basic sugar, glucose has the chemical formula C6H12O6. The most prevalent monosaccharide, a type of carbohydrate, is glucose.
The primary form of sugar in the blood, glucose serves as the body's cells' main source of energy. Glucose can be produced by the body from other chemicals, or it can be obtained from the meals we eat. The bloodstream carries glucose to the cells. Insulin is one of many hormones that regulate blood glucose levels.
The brain is the most energy-hungry organ in the body and uses half of the body's sugar energy due to its abundance of nerve cells, or neurons. Thinking, memory, and learning are all tightly correlated with blood glucose levels and how effectively the brain uses this substance.
Thus, a homopoloymer of glucose is corn starch.

Answer:
B) 88.6%
Explanation:
Percent yield equals actual yield divided by theoretical yield
actual yield is 31.0g
theoretical yield is 35g

Answer: K only has 1 valence electron. It will leave with only a little effort, leaving behind a positively charged K^+1 atom.
Explanation: A neutral potassium atom has 19 total electrons. But only 1 of them is in potassium's valence shell. Valence shell means the outermost s and p orbitals. Potasium's electron configuration is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1. The 4s orbital is the only orbital in the 4th energy level. So it has a valency of 1. This means this electron will be the most likely to leave, since it is the lone electron in the oyutermost energy level (4). When that electron leaves, the charge on the atom go up by 1. The atom now has a full valence shell of 3s^2 3p^6, the same as argon, Ar.
