Answer:

298.15 K.

Explanation:

Room temperature is generally taken to be 25 °C (around 77 °F). 0 °C is equivalent to 273.15 K, so we add 273.15 to 25 to find that room temperature is around 298.15 K

A solution is made by dissolving 10.7 g of magnesium sulfate, MgSO4, in enough water to make exactly 100 mL of solution. Calcula
adell [148]

Answer:

[MgSO₄] = 890 mM/L

Explanation:

In order to determine molarity we need to determine the moles of solute that are in 1L of solution.

Solute: MgSO₄ (10.7 g)

Solvent: water

Solution: 100 mL as volume. (100 mL . 1L / 1000mL) = 0.1L

We convert the solute's mass  to moles → 10.7 g / 120.36 g/mol = 0.089 moles

Molarity (mol/L) → 0.089 mol/0.1L = 0.89 M

In order to calculate M to mM/L, we make this conversion:

0.89 mol . 1000 mmoles/ 1 mol = 890 mmoles

Name the following compound: CH3 – CH2 – CH = CH – CH3<br><br> Fill In The "___"<br><br> 2-Pen ___
swat32

Answer: 2-Pentene

Explanation:

The longest continuous carbon chain that contains the double bond is identified to be Pentene, since it has five carbon atoms.The presence of the double bond makes it an Alkene, hence the -ane ending of the parent Alkane is changed to -ene.

We then do our numbering in the direction that gives the position of the double bond a lower number. Numbering from right to left, the position of the double bond is at carbon atom 2 going to 3, which is lower compared to the other direction.

Hence the name of the compound is 2-Pentene.
