Answer:

When an element or substance is in a liquid state, the particles are joined by less attractive forces than in solids, for this reason the particles of a liquid can move freely.For this reason the particles of a liquid can move freely and need a recipient that contains them .

Liquids have a defined volume but with a variable shape, this means that liquids adopt the shape of the container but always occupy the same space

For example, if we have 4 L of water in a round container, its shape is round and now we put the water in a square container, its shape is now square but its volume is still 4 L (it continues to occupy the same space)

liquid is fluid in motion, needing to be contained. while a solid state of matter is as such and won't run down the cabinet

Answer: 1.14

Explanation:

$HCl+NaOH\rightarrow NaCl+H_2O$

To calculate the molarity of acid, 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 $HCl$

are the n-factor, molarity and volume of base which is NaOH.

We are given:

$n_1=1\\M_1=?\\V_1=10.0mL\\n_2=1\\M_2=0.1M\\V_2=7.2mL$

Putting values in above equation, we get:

$1\times M_1\times 10.0=1\times 0.1\times 7.2\\\\M_1=0.072M$

To calculate pH of gastric juice:

molarity of $H^+$ = 0.072

$pH=-log[H^+]$

$pH=-log(0.072)=1.14$

Thus the pH of the gastric juice is 1.14

If a buffer solution is 0.190 m in a weak acid (ka = 8.2 × 10-5) and 0.590 m in its conjugate base, what is the ph?\

Lubov Fominskaja [6]

<span>You use the Henderson - Hasselbalch equation pH = pKa + log ([salt]/[acid]) pKa = -log (8.2*10^-5) = 4.081 pH = 4.081 + (0.590/0.190) pH = 4.081 + log 3.105 pH = 4.081 + 0.49206 pH = 4.573</span>

Calculate the number of moles of gas in the following at STP: 45.6 L of H2 gas

zimovet [89]

Answer:

2.04 mol

Explanation:

At STP, 1 mole = 22.4 L

45.6 L of H2 * (1 mole of H2 / 22.4 L ) = 2.04 mol
