Answer:

The mount of heat required is 249.690 kJ.

Explanation:

Mass of the water,m =337 g

Specific heat capacity of the water,c = 4.186 J/g °C

Change in temperature =\Delta T=177^oC-0^oC=177^oC

Q = Heat required

Q=mc\Delta T=337 g\times 4.186 J/g ^oC\times 177^oC=249,690.7 J=249.690 kJ

1 kilo Joule = 1000 joules

The mount of heat required is 249.690 kJ.

Find the ph of of 100 ml of an aqueous 0.43m baoh2 solution
denpristay [2]
Answer is: pH of barium hydroxide is 13.935.
Chemical dissociation of barium hydroxide in water:
Ba(OH)₂(aq) → Ba²⁺(aq) + 2OH⁻(aq).
c(Ba(OH)₂) = 0.43 M.
V(Ba(OH)₂) = 100 mL ÷ 1000 mL/L = 0.1 L.
n(Ba(OH)₂) = 0.43 mol/L · 0.1 L.
n(Ba(OH)₂) = 0.043 mol.
From chemical reaction: n(Ba(OH)₂) : n(OH⁻) = 1 : 2.
n(OH⁻) = 0.086 mol.
c(OH⁻) = 0.86 mol/L.
pOH = -logc(OH⁻).
pOH = 0.065.
pH = 14 - 0.065 = 13.935.

Why wouldn't two cations form a covalent bond?
Allushta [10]

Answer:

Covalent bonding is the sharing of electrons between atoms. In addition, the ionization energy of the atom is too large and the electron affinity of the atom is too small for ionic bonding to occur.

For example: carbon does not form ionic bonds because it has 4 valence electrons, half of an octet.

Evaluate the following conversion. Will the answer be correct? Explain. If incorrect, how could you adjust one of the factors to
elena55 [62]

Given :

Rate = 75 m 1 s×60 s 1 min×1 h 60 m.

To Find :

Correct answer after conversion.

Solution :

We know, 1 min = 60 sec.

1 hour = 60 min = 60×60 sec = 3600 sec.

Putting value of min and hour in seconds , we get :

R=((75\times 60) + 1 )\times ( (60 + 1)\times 60 ) \times ( 3600+3600)\ s^3\\\\R=1.186\times 10^{11} \ s^3

Hence, this is the required solution.
