Answer:
Let's assume that the erosion rate is "X/hour". The total volume of sand on a beach after 24 hours would be,
= total sand volume - (erosion rate per hour * 24)
= 1,278m - (X/hour * day)
Explanation:
Now assume that the erosion rate is 1 m per hour. Therefore, in 24 hours would be,
= 1,278m - (1/hour * 24)
= 1,278 - 24
= 1254 m.
Answer:
That means an atom with a neutral charge is one where the number of electrons is equal to the atomic number. Ions are atoms with extra electrons or missing electrons. When you are missing an electron or two, you have a positive charge. When you have an extra electron or two, you have a negative charge.
Explanation:
We assume you are converting between grams ZnSO4 and mole. You can view more details on each measurement unit: molecular weight of ZnSO4 or mol This compound is also known as Zinc Sulfate. The SI base unit for amount of substance is the mole. 1 grams ZnSO4 is equal to 0.0061941519772353 mole.
Answer:
B. Aromatic
Explanation:
Functional groups are groups that differentiate a specific organic compound from others. A functional group determines the chemical property of the compound that possesses it.
For example, just like alkene and alcohol functional groups have characteristics double bond (=) and hydroxyl (OH) group respectively, the image in the attachment of this question has a BENZENE RING at the core of its structure, hence, the organic compound can be regarded to have an AROMATIC FUNCTIONAL GROUP.
Molecular weight it stands for molecular weight
