In carbon monoxide, CO, the mass ratio is 1.00 g of carbon for every 1.33 g of oxygen. How many grams of oxygen will be combined
notsponge [240]

Answer : The mass of oxygen combined with 1.00 g of carbon in carbon dioxide will be, 2.66 grams.

Explanation :

Law of multiple proportion : It states that when two elements can combine to form two or more different compounds then the mass of one element compared to fixed mass of the other will always be in a ratio of small whole numbers.

As we are given that the mass of ratio of carbon and oxygen in CO is 1 gram and 1.33 gram.

Ratio of C and O in CO = 1 : 1

Ratio of C and O in CO₂ = 1 : 2

So, the mass of ratio of carbon and oxygen in CO₂ will be 1 gram and (2×1.33) 2.66 gram.

Thus, the mass of oxygen combined with 1.00 g of carbon in carbon dioxide will be, 2.66 grams.

What force is necessary to accelerate a 1,200 kg car at a rate of 35 m/s2?
Zarrin [17]

Explanation:

Given that,

Mass of a car, m = 1200 kg

Acceleration of the car, a = 35 m/s²

The force acting on the car is given by :

F = ma

F = 1200 kg × 35 m/s²

= 42000  N

If the force is 30,600 N, then acecleration is given by :

a=\dfrac{F}{m}\\\\a=\dfrac{30600}{1200}\\\\a=25.5\ m/s^2

Hence, this is the required solution.
