To completely balance the equation, we do elemental balance. First for C, the C in the left side is 5 so there must be 5 CO2. Balancing the H, H20 must be 9/2 to balance the left side. The total O on the right is 29/2. In the left side, O2 must be 27/4. Multiplying by 4 to get whole number stoich.coeff, we get 4 C5H9O + 27O2 = 20 CO2 + 18 H2O.
Answer:
Explanation:
All compounds are molecules, but not all molecules are compounds. That is because a molecule can be made up of two atoms of the same kind, as when two oxygen atoms bind together to make an oxygen molecule. However, all compounds are made up of two or more different types of atoms.
Answer:
10 kilowatts or 10,000 kw
Explanation:
Power = Force × Velocity
Given that:
Velocity of car is 50 m/s
The force is 200N
The power would be:
P = 200 × 50
P = 10,000 W
Notice that it only reaches watts because of the unit of the velocity is m/s. Standard unit to make Kw is km.
Since:
1 kw = 1000 w
10 kw = 10000 w

Answer:
Explanation:
El hielo encierra la primavera antes de espolvorear la sal.
Cuando se rocía sal sobre el hielo, disminuye el punto de fusión del hielo 32 ° F a un poco por debajo de 32 °, por lo tanto, se acumula.
A medida que el hielo se vuelve a congelar, encierra la primavera
The ball travels 10m/s
Speed = distance/time
