Explanation:
Answer:
780 watts
Explanation:
formula to find power when given amps and voltage
P = A x V
=6.50a x 120V
= 780 W (watts)
Answer:
2.765 × × 10³ moles of O₂
Explanation:
The chemical equation to produce water from oxygen and hydrogen is;
2H₂ (g) + O₂ (g) = 2H₂O (l)
From the equation above, we see that;
2 moles of H₂O is produced from 1 mole of O₂
Thus; 5.53 × 10³ moles of H₂O will require;
(5.53 x 10³ moles of H₂O × 1 mole of O₂)/2 moles of H₂O = 2.765 × × 10³ moles of O₂
Answer:
1.2029 J/g.°C
Explanation:
Given data:
Specific heat capacity of titanium = 0.523 J/g.°C
Specific heat capacity of 2.3 gram of titanium = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
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
1 g of titanium have 0.523 J/g.°C specific heat capacity
2.3 × 0.523 J/g.°C
1.2029 J/g.°C
