Answer:
Heat transfer = Q = 62341.6 J
Explanation:
Given data:
Heat transfer = ?
Mass of water = 50.0 g
Initial temperature = 30.0°C
Final temperature = 55.0°C
Specific heat capacity of water = 4.184 J/g.K
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 55.0°C - 30.0°C
ΔT = 25°C (25+273= 298 K)
Q = 50.0 g × 4.184 J/g.K ×298 K
Q = 62341.6 J
<span>The Law of Conservation of Mass simply states
that the total amount of mass should not change in a chemical reaction that is
isolated (no other objects can enter the reaction). The total mass of the
reactants must be equal to the total mass of the products. Thus, t</span>he correct estimate of
the amount of oxygen used in the interaction is the difference between 133
g and 29 g.
I believe the answer is increases , decreases
Matter- Anything that occupies space and has mass is called matter.That is they have both mass and volume.
Apple is an example of matter because it occupies space and has mass and volume.
10,573.4
Explanation:
Given parameters:
Dosage per patient = 73ap/lbs
Weight of patient = 65.7kg
Unknown:
Amount of grams/ap to be given to the patient;
Solution:
Since our final answer should be expressed in grams, let us convert all units into grams.
1000g = 1kg
Converting 65.7kg to g = 65.7 x 1000 = 65700g
73ap/lbs;
1lb = 453.6g
73ap/lbs x 
= 0.161ap/g
Now,
For a 65700g person, the number of grains app required;
65700 x 0.161 = 10,573.4grains ap per dose
