Hey there!

Your question states: <span>You dissolve 0.005 mol of potassium chloride (KCI) in0.50 L of water. What is the molarity of the solution? So, basically in this question here, this would be just like converting the cup's to gallons. It would be the </span>exact same thing.

The, when doing this problem, we would do the following . . .

$\left \{\boxed{\boxed{0.005}} \ divided \ by \ \boxed{\boxed{0.50}} \ { \atop {}} \right.\}$

$and \ from \ doing \ this, \ we \ get \ for \ your \ and . . .$

$\boxed{\boxed{ .01m}}$

Hope this helps.

For each molecule of glucose processed during glycolysis, the net yield is ____. 1. two molecules of NADH, two of ATP, and two o

Lana71 [14]

Answer: 1. two molecules of NADH, two of ATP, and two of pyruvate

Explanation:

During glycolysis 4 molecules of ATP are synthesized by two substrate level phosphorylation (first in step 6 conversion of 1,3-Bisphospho glycerate to 3-Bisphospho glycerate by 1,3-Bisphospho glycerate kinase produces 2 molecules of ATP . Secondly 2 molecules of ATP is produced in step 9 by pyruvate kinase). But 2 molecules of ATP are used in step 1 and 3 by hexokinase and phospho fructo kinase respectively, hence a net yield of only two ATP.

2 molecules of NADH is produced in step 5 by Glyceraldehyde-3-phosphate dehydrogenase.

The end product of glycolysis is 2 molecules of pyruvate.

A 312 g sample of a metal is heated to 257.128 °C and plunged into 200 g of water at a temperature of 41.933 °C. The final tempe

DENIUS [597]

<h3>Answer:</h3>

0.362 J/g °C

<h3>Explanation:</h3>

We are given:

Mass of metal = 312 g

Initial temperature of the metal = 257.128 °C

Mass of water = 200 g

Initial temperature = 41.933 °C

Final temperature of water = 67.555 °C

Specific heat capacity of water = 4.184 J/g °C

We are required to calculate the specific heat capacity of the metal;

Step 1: Heat gained by water

Quantity of heat = mass × specific heat × change in temperature

Q=m × c × Δt

Change in temperature, Δt = 25.622 °C

Therefore,

Heat gained by water = 200 g × 4.184 J/g °C × 25.622 °C

= 21,440.49 Joules

<h3>Step 2: Heat released by the metal </h3>

Change in temperature of the metal, Δt =(257.128 °C-67.555 °C)

= 189.573 °C

Q = mcΔt

Assuming the specific heat capacity of the metal is c

Q= 312 g × 189.573 °C × c

= 59,146.776c Joules

<h3>Step 3: Calculate the specific heat capacity of the metal</h3>

The heat released by the metal is equivalent to heat gained by water.

Therefore;

59,146.776c J = 21,440.49 J

c = 21,440.49 J ÷ 59,146.776

= 0.362 J/g °C

Thus, the specific heat capacity of the metal is 0.362 J/g °C
