What is 5.1821 x 10^-4 in standard format

jin has four colorful glass bottles on his windowsill. one is red, one is violet, one is green, and one is yellow. the light tha

Over [174]

The red bottle would have the lowest frequency because red light has the longest wavelengths. The light passing through the violet would have the highest frequency because its wavelengths are the shortest.

Part A Which of the following statements about chemical formulas is FALSE? Which of the following statements about chemical form

statuscvo [17]

Answer: Option (a) is the correct answer.

Explanation:

Subscript present in chemical formula of a compound represents the number of atoms of the element actually present in it.

For example, in $C_{7}H_{7}NO_{2}$ the subscripts present in it are 7, 7, 1, and 2.

A subscript is not responsible for determining the relative mass of each type of an atom because a subscript simply represents the number of atoms of each type of an element participating or combining with other atoms of a compound.

Thus, we can conclude that the statement subscripts represent the relative mass of each type of atom in the compound, is false.

A binary ionic compound is known to contain a cation with 51 protons and 48 electrons. The anion contains one-third the number o

7nadin3 [17]

Answer:

$SbCl_3$

Explanation:

The cation contains 51 protons and 48 electrons. The electrons are only lost not protons, so the element which corresponds to atomic number 51 is the cation which is Antimony (Sb).

Also, the charge on the cation is 51 - 48 = 3

This is because neutral atom contains the same number of electrons as protons.

Given the anion has one-third protons as cation which means thta:

Number of protons in anion = $\frac {51}{3}=17$

This corresponds to chlorine atom. The electrons are 1 greater than protons means that it has gain 1 electron.

So,

Sb Cl

3 1

Cross multiply the valency.

So, formula is $SbCl_3$
