Q=heat and Q=m*c*dekta(temp)
So we have
Q= 100g*4.184*50=20920J of heat energy
Q= 100g * 0.397* 50= 1985J of heat energy
So the water requires more energy and this is due to the higher heat capacity value of water than the metal sample
Please help me out and rate Brainliest if my answer helped you understand the concept and how to solve!! Any questions please just ask! Thank you so much!!
Answer:
The chemical symbol will be "
".
Explanation:
The given values are:
Current,
I = 2.50 amps
Time,
t = 2 hr
or,
= 7200 sec
Metal deposited,
W = 5.93 gm
As we know,
⇒ 
or,
⇒ 
On putting the given values, we get
⇒ 
⇒ 
hence,
⇒ 
⇒ 
⇒ 
Thus the above is the right answer.
The heart has 2 chambers: The UPPER CHAMBERS are called the <u>atrium</u> and the LOWER CHAMBERS are called the <u>ventricles</u>
Therefore , answer is c
Answer:
The correct answer is c add more HCO3- by adding NaHCO3.
Explanation:
The reaction mentioned in the question is carried out by bicarbonate buffer system of our body to maintain the normal acid base balance.
Now concentration of the reactant (H2C03) is decreased then NaHCO3 should be added which undergo breakdown to release bicarbonate ions(HCO3-).
The released bicarbonate ions then reacts with H+ to form Carbonic acid(H2CO3).Thus homeostasis of H2CO3 is maintained.
Answer:
The answer is the first option 0.37 moles
Explanation:
the ideal gas law is PV = nRT, so in the terms of n,
n = PV/RT (divide both sides by RT to let n stand alone)
given: P = 700 kpa, V = 2L, T = 450 K , R = 8.31
n = (700 * 2) / (8.31 * 450)
= 1400/3739.5
= 0.34
