Answer:

Acids give off H+ (Hydrogen) ions in water; bases give off OH- (Hydroxide) ions in water. Acids generally taste sour due to the sour H+ ion; bases taste bitter due to the OH- ion; but they may have other tastes depending on the other part of the molecule. Bases are usually soapy in nature.

What is the energy of a 4.66 x 1014 Hz wave?

docker41 [41]

I attached the working and the answer to both questions below.

Please note that E = energy, ν = frequency, h = Plank's Constant

The energy of a 4.66 x 10¹⁴ Hz wave is 3.088 × 10⁻¹⁷ J

PLEASE HELP! WILL GIVE BRAINLIEST:

Ad libitum [116K]

2.45 °C

From the Ideal gas law (Combined gas law)

PV/T = P'V'/T' .....eq 1

Where:

P - initial pressure

V - initial volume

T - initial temperature

P' - final pressure

V' - final volume

T' - final temperature.

To proceed we have to make T the subject from eq.1

Which is, T = P'V'T/PV.......eq.2

We have been provided with;

Standard temperature and pressure (STP)

P = 760 mm Hg (SP - Standard Pressure)

T = 273.15 K (ST - Standard Temperature)

V = 62.65 L

P' = 612.0 mm Hg

V' = 78.31 L

T' = ? (what we require)

Therefore, we substitute the values into eq.2

T' =

T' = 275.60 K

T = (275.60 - 273.15) ......To °C

T = 2.45 °C

A chemist prepares a solution of iron chloride by measuring out 0.10 g of FeCl2 into a 50. mL volumetric flask and filling to th

Tanya [424]

Answer: The molarity of anions $(Cl^-)$ in the solution is 0.0316 M

Explanation:

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Given mass of iron (II) chloride = 0.10 g

Molar mass of iron (II) chloride = 126.75 g/mol

Volume of solution = 50 mL

Putting values in above equation, we get:

$\text{Molarity of iron (II) chloride}=\frac{0.10\times 1000}{126.75\times 50}\\\\\text{Molarity of iron (II) chloride}=0.0158M$

1 mole of iron (II) chloride produces 1 mole of $Fe^{2+}$ ions and 2 moles of $Cl^-$ ions

So, concentration of chloride ions (anions) in the solution = $(2\times 0.0158)=0.0316M$

Hence, the molarity of anions $(Cl^-)$ in the solution is 0.0316 M

In the energy diagram, which number represents the activation energy of the forward reaction?

nexus9112 [7]

You didn't send a picture. But the activation energy is always the difference between the starting point and the highest point in the graph
