Answer:

∆o

Explanation:

Usually, the d level consists of a set of five degenerate d orbitals. These orbitals rema degenerate until the approach of ligands.

When ligands approach, the d orbitals are split into higher energy eg and lower energy t2g orbitals.

There exists an energy difference between this t2g and eg levels. This energy difference is called the octahedral crystal field splitting denoted as ∆o.

a 150 g sample of water (initially at 45 C) is mixed with an unknown mass of water (initially at 84 C). the final temperature of

Evgesh-ka [11]

Answer : The unknown mass of water is, 200.3 grams.

Explanation :

In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.

$q_1=-q_2$

$m_1\times c_1\times (T_f-T_1)=-m_2\times c_2\times (T_f-T_2)$

As,

$c_1=c_2$ = specific heat water

So,

$m_1\times (T_f-T_1)=-m_2\times (T_f-T_2)$

where,

$m_1$ = mass of water = 150 g

$m_2$ = mass of unknown water = ?

$T_f$ = final temperature of mixture = $67.3^oC$

$T_1$ = initial temperature of water = $45^oC$

$T_2$ = initial temperature of unknown water = $84^oC$

Now put all the given values in the above formula, we get

$150g\times (67.3-45)^oC=-m_2\times (67.3-84)^oC$

$m_2=200.3g$

Therefore, the unknown mass of water is, 200.3 grams.

0.632 mole of carbon dioxide is produced in a chemical reaction at STP. What

levacccp [35]

Answer:

V = 14.2 L

Explanation:

Given data:

Moles of CO₂ = 0.632 mol

Temperature = standard = 273 K

Pressure = standard = 1 atm

Volume of gas = ?

Solution;

Formula:

PV = nRT

R = general gas constant = 0.0821 atm.L/ mol.K

Now we will put the values in formula.

V = nRT/P

V = 0.632 mol ×0.0821 atm.L/ mol.K × 273 K / 1 atm

V = 14.2 L/ 1

V = 14.2 L
