Answer:
Saliva, which contains assorted enzymes that begin digestion; an example is amylase, which begins digestion of carbohydrates by digestion into simpler sugars
Explanation:
Answer:
No, these sample could no be same
Explanation:
Percentage of copper in both sample are different means both are taken from different sample because if we says both are from same sample then its violates the law of definite proportion
according to this law a given compound always contains same proportion of element by mass and it does not depend on the source
eg: water from sea and drainage both have same composition means same amount of oxygen and hydrogen by mass is present
Hence given samples are not same
I think the correct answer is C. Neutrons do not affect how atoms bond due to their neutral charge which makes it so that they don't affect the movement of electrons at all (chemical reactions occur when electrons are transferred/shared). Neutrons due however have a mass similar to that of a proton which means they contribute to the mass of the atom. Neutrons also effect the stability of the nucleas as shown in atoms that have radioactive isotopes. I hope this helps. Let me know if anything is unclear.
Answer:
<h3>Exothermic Process</h3>
Explanation:
<h3><u>Answer;</u></h3>
= 3032.15 kPa
<h3><u>Explanation;</u></h3>
Using the equation;
PV = nRT , where P is the pressure,. V is the volume, n is the number of moles and T is the temperature and R is the gas constant, 0.08206 L. atm. mol−1.
Volume = 7.5 L, T = 274 +273 = 547 K, N = 5 moles
Therefore;
Pressure = nRT/V
= (5 × 0.08206 × 547)/7.5 L
= 29.925 atm
But; 1 atm = 101325 pascals
Hence; Pressure = 3032150.63 pascals
<u>= 3032.15 kPa</u>
