Answer:

[KOH] = 0.10M in KOH

Explanation:

Molar Concentration [M] = moles solute/volume solution in liters

moles KOH = 0.56g/56g/mole = 0.01mole

Volume of solution = 100cm³ = 100ml = 0.10 liter

[KOH] = 0.01 mole KOH / 0.10 liter solution = 0.10M in KOH

Which is a correct comparison between the modern quantum model and John Dalton’s model of the atom?
Greeley [361]

Answer:

The modern model recognizes particles in the atom, whereas Dalton’s model does not.

Explanation:

The modern model considers the atom to consist of electrons, protons, and neutrons.

A is wrong. The modern model of the atom is widely accepted.

B is wrong. Dalton assumed that all atoms are identical. The modern model recognizes that there are isotopes of atoms.

D is wrong. The modern model explains emission spectra. Dalton's model does not.

A sample of water (88 grams) had a temperature change of 6.0 ℃. What was the heat change of this sample? (q = m c ΔT, c = 4.18 J
jeka94

Answer:

Q=2209J

Explanation:

Hello!

In this case, since the heat involved during a heating process is computed in terms of mass, specific heat and temperature change as shown below:

Q=mC\Delta T

Thus, since the heated mass of water was 88 g, the specific heat of water is 4.184 J/g°C and the temperature change is 6.0 °C, we can compute the heat as shown below:

Q=88g*4.184\frac{J}{g\°C}*6.0\°C \\\\Q=2209J

Best regards!
