So we have: 1 C2H5OH + _ O2 -> 2 CO2 + _ H2O Step 3: The only molecule on the right that is left is H2O. We start with 6 hydrogen atoms<span> on the left.</span>
Answer:
It is C
Explanation:
It is Cutting paper because cutting paper doesn't alter the chemical composition of paper
Ice is less dese than water
It is transferred by conduction when two objects at two different temps touch each other, and the one with the most heat will transfer its heat to the cooler object until they both have the same temperature..
At the point of touching the fast moving molecules of the warmer object will collide with the slower moving molecules of the cooler object.
Answer:
Explanation:
Force is equal to mass times acceleration.
By dividing both sides by m, we rearrange the formula for a (acceleration).
The force is 6.2 Newtons, but we can convert the units to make the problem easier later on.
- A Newton is equal to 1 kg*m/s², so 6.2 N is equal to 6.2 kg*m/s².
The mass is 2300 grams, but we need to convert it to kilograms.
- To convert grams to kilograms, divide by 1,000
- 2300 g/1000= 2.3 kg
Substitute the values into the formula.
Divide. Note that the kilograms or "kg" will cancel each other out (this is why we converted the units).
Round to the nearest tenth. The 9 in the hundredth place tells us to round up to 2.7
The acceleration is about <u>2.7 meters per second squared.</u>
