The solid is not completely submerged in the water. Will this technique error increase, decrease, or have no effect on the repor

This technique error will increase the reported density of the solid.

Since the solid isn't completely submerged in the water, the volume will be reported as less than it actually is. Since volume is inversely proportional to density (if one goes up the other goes down), the density will increase and be reported as more than it actually is.

What is the name of the molecular compound SF 5? sulfur pentafluoride sulfur hexafluoride sulfur heptafluoride monosulfur tetraf
romanna [79]

Answer: sulfur pentafluoride

Explanation:

The rules for naming of binary molecular compound :

In the given formula, the lower group number element is written first in the name and keep its element name and the higher group number is written second.

First element i.e. sulphur in the formula is named first and keep its element name.

1) Gets a prefix if there is a subscript on it such as mono for 1, di for 2, tri for 3 and so on.

Second element i.e. fluorine is named second.

1) Use the root of the element name, if it is an anion then use suffix (-ide).

2) Always use a prefix on the second element such as mono for 1, di for 2, tri for 3 and so on.

Therefore, the chemical name of compound SF_5 is sulfur pentafluoride

One method used commercially to peel potatoes is to soak them in a solution of NaOH for a short time and then remove them from t
sergij07 [2.7K]

Answer:

b. 2.28 M

Explanation:

The reaction of neutralization of NaOH with H2SO4 is:

2NaOH + H2SO4 → Na2SO4 + 2H2O

<em>Where 2 moles of NaOH react per mole of H2SO4</em>

<em />

To solve the concentration of NaOH we need to find the moles of H2SO4. Using the chemical equation we can find the moles of NaOH that react and with the volume the molar concentration as follows:

<em>Moles H2SO4:</em>

45.7mL = 0.0457L * (0.500mol/L) = 0.02285 moles H2SO4

<em>Moles NaOH:</em>

0.02285 moles H2SO4 * (2moles NaOH / 1 mol H2SO4) = 0.0457moles NaOH

<em>Molarity NaOH:</em>

0.0457moles NaOH / 0.020L =

2.28M

Right option:

<h3>b. 2.28 M</h3>
