3 0

Answer:

Yes! That is correct.

Explanation:

0°C = 273.15 K, so in order to convert from Celsius degrees (°C) to Kelvin (K) you have to add 273.15 to the value in Celsius degrees.

You will have a 500mL solution of salt water. From this you will take 10.0mL and place it on a balance. You find that the 10.0mL
anastassius [24]
<h2>Answer:</h2>

Given data:

Volume of solution: 500 ml

Mass of 10 ml solution: 10.7 g

Density of whole solution: ?

<h3>Solution:</h3>

Mass of 500 ml solution : 10.7/10 * 500 =  535 g

Density = Mass/ volume

<u>Putting values in formula :</u>

D = 535/500 = 1.07 g/ml

                                         Hence    Density = 1.07 g/ml

whats the specific heat of an unknown substance if the addition of 800 joules of heat energy caused a 30 gram sample to warm fro
Troyanec [42]

 The specific heat capacity of unknown  substance  is 1.333 g/j/°c


  <u><em> calculation</em></u>

 Specific heat capacity is calculated using  Q= MCΔT  formula

where;

Q(heat)= 800 j

M(mass) = 30 g

C(specific heat  capacity) =?

ΔT( change in temperature)  = 40°c - 20°c = 20°c

make C  the subject of the formula  by diving both side of the formula by MΔT

C  is therefore = Q/MΔT

800j / 30 g x  20°c = 1.333 j/g/°c

Why in anaerobic conditions is nadh oxidized by lactate dehydrogenase.
stiv31 [10]

Answer:

It is in the oxidation of NADH to NAD + that lactate dehydrogenase (LDH) plays an important role. LDH catalyzes the following reaction The lactate then diffuses out of the cell and the NAD + is used to continue glycolysis.It is in this manner that the cell continues to produce energy under anerobic conditions.
