Answer:
I believe
Explanation:
I believe that the answer is B, but I could be wrong. I think it's How much work can be done in a given time, because, In physics, power is the amount of energy transferred or converted per unit time.
Answer:
from the 1st equation:
4NH3 4NO
4 *(68) 4*30
1216 X mass of NO = 536.5 g
from the 2nd Equation
2NO 2NO2
2*30 2* 46
536.5 x mass of NO2 = 822.6 grams
from the 3rd Equation
3NO2 2HNO3
3*(46) 2* (63)
822.6 X mass of nitric acid = 751.06 gram
b) % yields = ( 96.2%* 91.3% *91.4%)= 80.3%
The answer for the following problem is mentioned below.
Explanation:
Given:
mass of iron (m) = 15.75 grams
heat (q) = 1097 J
initial temperature (
) = 25°C
final temperature (
) = 177°C
To find:
specific heat (c)
We know;
c = q ÷ mΔT
where;
c represents the specific heat
q represents the heat
m represents the mass
t represents the temperature
c = 
c = 0.45 J/kg°C
<u><em>Therefore the specific heat capacity of iron is 0.45 J/kg°C.</em></u>
Explanation:
The grey powder of silver ( I ) oxide i.e. Ag₂O breaks down to give a metal called the silver metal and an odorless , colorless gas , which is the oxygen gas .
The balanced chemical reaction is as follows -
Silver oxide -----> Silver + oxygen
Ag₂O ------> Ag (s) + O₂ (g)
The balanced reaction is -
2 Ag₂O (s) ------> 4 Ag (s) + O₂ (g)
Neutron or neutral and electran are positive
