Spontaneity.... 
There are two components which together decide whether a procedure is unconstrained or not: enthalpy change (ΔH) and entropy change (ΔS). Procedures which are unconstrained move from a higher vitality to a lower vitality and hinted at by the Gibbs free vitality. 
ΔG = ΔH - TΔS 
A negative ΔG shows an unconstrained procedure. Regardless of whether the enthalpy change is certain the entropy change can likewise be sure, which influence the estimation of ΔG to negative, demonstrating an unconstrained procedure. This makes sense since in the broke down state, where a substance is part separated into particles, the quantity of microstates will be more prominent (expanding entropy).

What volume of 3.00 M HCl will form a solution with an acidic pH when mixed with 100 mL of 3.00 M NaOH
Maksim231197 [3]

<u>Answer:</u> The volume of acid should be less than 100 mL for a solution to have acidic pH

<u>Explanation:</u>

To calculate the volume of acid needed to neutralize, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid which is HCl

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base which is NaOH

We are given:

n_1=1\\M_1=3.00M\\V_1=?mL\\n_2=1\\M_2=3.00M\\V_2=100mL

Putting values in above equation, we get:

1\times 3.00\times V_1=1\times 3.00\times 100\\\\V_1=\frac{1\times 3.00\times 100}{1\times 3.00}=100mL

For a solution to be acidic in nature, the pH should be less than the volume of acid needed to neutralize.

Hence, the volume of acid should be less than 100 mL for a solution to have acidic pH

How much heat energy is required to raise the temperature of 0.367 kg of copper from 23.0 C to 60.0 C ? The specific heat of cop
mojhsa [17]
Note: We must keep the units we use consistent. The Cp is given in cal/gC so we will use cal for energy, grams for mass and C for temperature.
1)
Heat supplied can be calculated using:
Q = mCpΔT; where m is the mass, Cp is the specific heat capacity and ΔT is the temperature change.
Q = 367 x 0.092 x (60 - 23)
Q = 125 Cal

2)
Using the same equation:
125 = 60 x 0.092 x (T - 23)
T = 45.6 C

What does it mean for a element of a group to have a order?
lisabon 2012 [21]

In group theory, a branch of mathematics, the term order is used in two unrelated senses:

<span><span>The order of a group is its cardinality, i.e., the number of elements in its set. Also, the order, sometimes period, of an element a of a group is the smallest positive integer m such that <span>am = e</span> (where e denotes the identity element of the group, and am denotes the product of m copies of a). If no such m exists, a is said to have infinite order.</span><span>The ordering relation of a partially or totally ordered group.</span></span>

This article is about the first sense of order.

The order of a group G is denoted by ord(G) or | G | and the order of an element a is denoted by ord(a) or | a |.
