Answer: fuel cells have a higher efficiency than diesel or gas engines. Most fuel cells operate silently, compared to internal combustion engines.
Explanation:
The brain communicates with the rest of your body by sending signals throughout your body and then the body sends signals up to the brain asking what to do and then the brain sends a signal with directions on what to do.
Hope this helps!
Answer:
122.5 Joule, or 122.5 j
Explanation:
Given,
mass of the object (m) = 5 kg
velocity of the object (v) = 7 m/s
Kinetic energy = × m × v²
Applying the formula:
Kinetic energy = × 5 × 7²
⇒ × 5 × 7 × 7
⇒
⇒ 122.5 Joule, or 122.5 j
Kinetic energy is the energy that an object gains as the result of the motion. It also depends on the mass of the object and force with which the motion is applied. In the given question, the mass of the object is 5 kg and the force of the velocity by which it is moving is 7 m/s.
Answer:
A. Perchloric acid and potassium hydroxide
B. Trioxonitrate V acid and Cesium hydroxide
C. Hydroiodic acid and calcium hydroxide
Explanation:
An acid reacts with a base to form salt and water. The acid and the base that reacted for each of the compounds have been written in the answer above. The reaction equations are given below:
A. HClO4 (aq) + KOH (aq) ———> KClO4 (aq) + H2O (l)
B. HNO3 (aq) + CsOH (aq) ———-> CsNO3 (aq) + H2O (l)
C. 2HI (aq) + Ca(OH)2 (aq) ———> CaI2 (aq) + 2H2O (l)
Answer:
Let's do it like this...
The question says write a balanced equation for the reaction between aqueous lead(II) nitrite and aqueous potassium chloride to form solid lead(II) chloride and aqueous potassium nitrite...
Analysising
________________________________________________________
Aqueous Lead(II) Nitrate written as a Formula is Pb(NO3)2 and Aqueous potassium written as a Formula is KOH.......and.......here the statement says they form Solid lead(ll) chloride which is PbCl₂ and aqueous potassium nitrite which is KNOH3
so The unbalanced equation will be
Pb(NO3)2 + KCL ====> PbCl2 + KNOH3
________________________________________________________
New Balanced Equation
________________________________________________________
Pb(NO3)2 + 2KCL ====> PbCl2 + 2KNOH3
(Balanced) RHS = LHS
Explanation:
Balancing The Equation
Lead (Pb) Has a coefficient of 1 both side.(Balanced)
Nitrate (NO3) has 2 as their coefficient both sides. (balanced)
Potassium (K) has a coefficient of 2 in the left so in the right. (balanced)
Chlorine (Cl) has also a coefficient of 2 in the right so in the left. (balanced)
Therefore the equation is balance the LHS equals to the RHS
NB : There's no any balanced equation than this
