Answer:
One can of cola contain 0.16 kcal of carbohydrates.
Explanation:
Given data:
mass of cola can = 40 g
kilocalories of carbohydrates = ?
Solution:
we know that there are 4 cal of carbohydrates per gram.
40 g × 4 cal/g = 160 cal
Now we will convert calories into kilocalories. There are 1000 calories in one kilocalories so,
160/1000 = 0.16 kcal
so, one can of cola contain 0.16 kcal of carbohydrates.
The chemical reaction of magnesium and sodium hydroxide would yield magnesium hydroxide and sodium. The chemical reaction is expressed as:
Mg(s)+ 2NaOH(aq)→Mg(OH)2(s)+2Na
In ionic form,
Mg(s) + 2Na+ + 2OH−(aq)→Mg(OH)2(s) + 2Na
False it's composed of 3 phosphate groups not phenol
The number of boxes is calculated by dividing the
total mass of hardware boxes by 1.00 kg
<h3>What is a hardware?</h3>
A hardware is a physical component of a system that can be touched and felt.
Because hardware are physical components, they always have a given mass.
Assuming, several hardware each of mass 1.00 kg is available to be chosen from.
Also, assuming that the sum total of the mass of all the hardware is known.
The number of boxes can be calculated as follows:
- total mass of hardware/1.00 kg
Therefore, the number of boxes is obtained by dividing the sum of the mass of the boxes by 1.00 kg.
