Answer:

Hello, your answer here is D - the apple still in the tree. Potential energy is the energy possessed by an object by virtue of its position. As height increases, so does the potential energy of an object. The apple at the highest position has the greatest potential energy.

Select the more electronegative element in each pair.a.Cl or Fb.Se or Oc.N or Asd.Na or Mg

liubo4ka [24]

Answer:

The answer to your question is below

Explanation:

Electronegativity is a measure of how strongly atoms attract electrons to themselves.

Process

Look for the electronegativity of each element and compare.

a) Cl = 3.16 F = 3.98 Fluorine has a higher electronegativity

b) Se = 2.55 O = 3.44 Oxygen has a higher electronegativity

c) N = 3.04 As = 2.18 Nitrogen has a higher electronegativity

d) Na = 0.93 Mg = 1.31 Magnesium has a higher electronegativity

In a hospital laboratory, a 10.0 mL sample of gastric juice (predominantly HCl), obtained several hours after a meal, was titrat

LiRa [457]

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
